Inside story of Alexa
On the Google the manhunt" Alexa", the simplified Chinese character as a result has more than 70,000s.Now," the Alexa rank" is already single phrase that the station-masters  mouth side of the local website often hangs most .So, is this Alexa why?It with what make local website look askance at?The Alexa have which fresh behaviors the secret that know?The origin reports the reporter to pass to inquire into and gather news, the effort restores one  Alexa that is true for the reader, among them, a lot of informations are first times to publish on the medium.

  Betray the Alexa

  Write down this topic, the reporter still fears the not satisfactory place, careful remember the recent inquisition to gather news, give reporter constitution fan the website of the 障 , toward the friend who the reporter provides the help, still have the reporter the oneself, all threw in to the Alexa biggest hot liver, say up from a certain meaning, we also are in common" betray the Alexa".

  The first some day, some weekly magazine in Peking just released" Chinese business website 100 strong" ranking, certainly, this ranking is for the flavor of necessary" business", but among them do the introduction to some websites, that medium quotes from the another to rank the data again unexpectedly to explain the value of these websites, this was quote from by" Chinese business website 100 strong" ranking of rank is the global website of" 著 of world the third square measures the organization of 评 - American Alexa" to rank.Certainly, that medium to the adduction that this Alexa rank, nothing but for explaining the authority that its" Chinese business website 100 strong" rank.But set up own" authority" with another" authority", explained that medium exactly to another" authority"- the approbation that Alexa rank.

  Who is the Alexa?

  In April 1996, the Alexa establishes in the United States, the that time is just a small website, mainly doing the classification to navigate.At that time, a lot of websites are all the Fans of the Yahoo, the Alexa just is just numerous heels breeze a member within.But the oneself of Alexa also has some techniques, is to carry on statisticsing and analyzing towards visitting the discharge of a certain Web  station point.Afterwards, the Alexa returns the manhunt engine service that provides the oneself with the development toward netizen.

  In July 1997, the Alexa released a software, is the Alexa Toolbar( the Alexa tool) of the 著 of now, this is an imbed the browser of Microsoft IE of tool, it at the customer visit each page of Web all send back a string of code toward Alexa, will that the related information for browse tell the Alexa.But customer would at the tool's up see it browse of the website is in global ll websiteses of rank the information, certainly, this be just the Alexa give of website rank.

  In 1999, the Alexa were procure by the American electronic commerce  flagship business enterprise" Amazon", becoming the subsidiary of whole 资 of the latter.

  In the spring of 2002, the Alexa gave up own manhunt engine, turning but cooperating with Google.The Google  Web of the all over world crawled along the procedure to construct a huge page  information database, this enriched the Web address database of URL of the oneself of Alexa biggest.At the same time, the Alexa also lets out stealthily to crawl along the procedure ownly, searching the unknown Web address on the Internet.Through many backlog of years, the Alexa the URL Web address database has already saved 40,000,000,000  Web address informations, exceeding the Google etc. manhunt engine, become the Internet up the most whole Web address information database.Everyday of the database of Alexa increases the quantity to be up to the 1 TB equally, carrying on to renew completely every two months can to database.

  Now, the Alexa tool in the world of" pack the amount of machine" already up ten million, but main work of Alexa be according to an information for return of tool of the all over global computer  customer table's top, browse to the global netizen to carry on the monitor habitually, and develop and sell various related product.Among them, there is the global website ranking of the most long 100,000 Web addresses, there is seniority analysis of aim at the some and particular profession website, aiming at the website discharge  monitor report that individual website make to order.The Alexa still provided a lot of free and basic informations, for example" global website 500 strong", still have" the simplified Chinese character website 100 strong", the netizens can look into the concerning a certain website to rank the history variety diagram alone on the Alexa, even can still at the same time to most 5 discharge of website and rank etc. the data carries on horizontal contrast that keeps the view.

  Though the Alexa provided the quite a few and worthy information on its website, it is real to depend on to become famous still that to is quoted from to combine the quilt medium to fried to make and caused the global website of the huge controversy to rank for many times everywhere.According to" the authorities declare" of the website of Alexa, public that global website of Alexa is total to rank is pass to collect all Alexas  tool return of information, through the calculation synthesizes to rank.From in this" the authorities declare", we are not difficult to see, the factor that affects the Alexa to rank is two, on is the information that the Alexa collect, two is an Alexa to carry on the deep processed calculation method to these informations.

  On the website of Alexa, the people can search the interview number of the website that it belong to to a certain and particular Web address, the Alexa provides a data that is called the Reach per  million users( each million customers interview person-time, brief name Reach) to mean to visit the number, what this data point is average number that everyday visit some one website in the each customer of 1,000,000 Alexas tool.For example, November 3 in 2004, the google.com Reach is worth to 178,500, is to say, this day in, there are near 18 myriad peoples in the each customer of 1,000,000 Alexas tool visitted the google.com.Have the interview number only, return the shortage to reflect a website circumstance browse by netizen, the Alexa still provided another data to the netizen that reflect to visit to the utilization rate of the particular website, this is the PageViews per user.( the each customer browses the page number, brief name PV)The PV value of the some website is the average value of the total number of pages that a customer of the Alexa tool of that website of all interviews of everyday browses on that website, but same person browses to the same page again to account to make only once on everyday.Return to take the interview data of the google.com of November 3 in 2004 as an example, this day, google.com PV value is 4.0, also is to say, the netizens that come to visits were equally to browse 4 pages on the website of google.com.

  Had these two pieces of Reach and PVses according to, the Alexa can press comprehensive discharge for global website to carry on to rank, it website of this rank to call the Traffic Rank( the discharge rank, calling the Rank), according to the Alexa on its website of hermeneutic, decide this Rank is Reach and PV several numbers with averageses, is also the square root of your product.Obviously, a Reach of website and the PV values are more high, its Rank is also more high.Still to take google.com as an example, it 4.0 of PV value say at the general website not on the whole high, but, because the Google searches the customer of the engine quite a few, its Reach value is far high in general website, make google.com Rank attain 3, also is to say, it is the third that the world of that very day of google.com rank.But the world rank the tallest website is a yahoo.com, the its Reach and the PV values are all opposite and very high in global website.

  Make use of and doubt

  The each hour engraves each time, global each one installed calculator terminals of the Alexa tool and will make collective report that terminal toward Alexa in the interview circumstance on the Internet.According to these informations, the Alexa will rank to do the re-count to the global website everyday, also is to say, it is everyday that Alexa rank renew of.This ranking renew everyday seems to be too to keep the view again because almost global ll websites are within the scope of Alexa monitor,, add the data that it is public and at any time can check again, make Alexa rank seem to be very in a lot of situations sensitive.

  Since 2003, the local Internet profession heats completely in the beginning, the website  CEOs that had been are heartless by the capitals to fling offs found back again in former days of felling, but the risk investment  houses really compare the last time.The COM foam is period smart many, the website wants to draw on the investment, must cancel the worry of the capital first, be regarded as to have already ascended the website of the city, also need the value that expresses the oneself to some explicit datas of the shareholders.At this time, the Alexa rank to be introduced domestic, although this website had never cause everyone's attention before, this ranking that it provide very quickly display the huge business value.

  Some website at the time of delivering to the business proposal toward investor, start have intention to lift not intentionally own once of Alexa rank, according to the logic that a certain everyone recognize tacitly, row at 300  websites of in the world always compare the row in the world 1000 the website of ares even have the value.Finally, in the an of" insider" it is rumored, the Alexa ranks on the Chinese Internet the big 噪 of fame, but at this time, far in the Alexa of the ocean the other shore but know not a thing to its Chinese Fanses.

  When the Alexa ranks the widespread approbation of get the industry in the beginning, finally someone starts make use of the Alexa to rank to create" value".Personal station-masters of website of large quantity starts study the Alexa to rank the rule, starting spread on the net various cheat the tool to Alexa, start publish to introduce the article that the Alexa cheats the method on a lot of websites, start appear the discussion that ranks to the Alexa in various forum.At that time, the Chinese Internet industry blew" tornado of Alexa".

  At the end of 2003, aim at this Alexa hot, some industry insiders start query the credibility that Alexa rank again, and reveal" inside story" that a lot of website cheat.In fact, have very many netizens to all ranked to mean the doubt to the Alexa, because of in big and parts of time of 2003, the Alexa rank up of world the website of the fourth in Sha-ho is two Korean websites, the Alexa is hermeneutic to this is, install the comparison of the Alexa tool in the Internet customer of Korea higher, so Alexa the sample data get in Korean netizen is higher, this cause Korea of two a website of families entered global ex- five.

  However, Alexa of hermeneutic seem to copy more more black, because the Alexa tool onlies have the English version always, since have no Chinese version, even have no Korean version, if to say the universality rate of the tool high, Euro-American nation should first hit.Have the net friend to think on these grounds, the Korean website is to depended to cheat to promote the website to rank, more someone think, since the Alexa did not release the tool of the localization edition toward nation of Asia at all, the nation of Asia should boycott the Alexa to rank determinedly.

  Anyway, from make track for to hold the stick to kill, the industry is some to Alexa concern and did not reduce.Enter since 2004, have a lot of  station-masters of website as usual at engage in mental drudgery the ground to want to rank" do up" to the Alexa of oneself's website, and made public the Alexa the gunnerses to also continued to keep in mind various purpose of 揣 to bombard with artillery the Alexa equally before.11 long leaves of this year are later on, the local website is on the Alexa of ranked to experience a large-scale collective slippery 坡 suddenly, various rumor beginning spreads in the netizen midstream, a kind of  parlance that relatively spread is, the Alexa start adjust the calculate way finally to counter-attack more and more China to cheat the website, people this" proper defend" that sees do is an Alexa, after all, a take ranking as what biggest point seller's website rely for existence is fair sex that it rank.

  Various hearsay can't solve to see the doubt of the guests to credibility of Alexa, in introduction of underneath because the local and essential medium have never carry on the thorough analysis and the report ways to Alexa technique,, the reader can see, probably the Korean website ranks high have another reason, and the so-called Alexa cheats the means also be much more than only this, ex- some medium  report way breaks for many times so and in brief, and, the Alexa also has the oneself to defend to cheat the means very brilliantly.However, in this text mention of cheat the means and nets up everywhere it is thus clear that of" cheat the treasure 典 " have the hypostatic dissimilarity, so, the Alexa can resist this kind of on many big degrees not to cheated the way to also hard to say familiarly.

  The DNA of the Alexa tool

  To want to make the clear Alexa to rank thoroughly whether can believe, must carry on the overall dissection to the Alexa global website the discharge monitor from the technique, certainly, the Alexa did not announce own technique detail from the beginning, reporter the decision" with that it way, return SHI BI3 JUAN ", since the Alexa declare its data source be that tool, the reporter decide to be first from break to solve the tool to commence.

  Be subjected to the reporter entrust, the expert's little wood of the Web technique of the inside of circle 著 , used evening, to the Alexa tool and it carried on the meticulous analysis toward the data that Alexa return, getting a lot of precious and all alone data.The little wood that many year agos did the research to the Alexa think that analyzed to announce to public some technique details with more hidden Alexa this time recently.

  The little wood tells the reporter, the operation mechanism of the Alexa tool of the latest edition in now with former have no too big change, whenever the customer opens the new page with the browser of IE that have the Alexa tool, the data that a set of the Alexa servers( data.alexa.com) will receive to encrypt wrap, this data wrap in of core information is more than ten parameters, these parameters includes the current web page address, page to open time, customer to carry to show resolution, the Alexa tool an edition number, that customer whether for the customer of" Amazon" etc., among them have an important and implicit parameter, through the little wood analysis, think is Alexa for each have already install of an automatically born number of ID of tool, this number should be a world only one.Alexa can the one who pass this ID wraps to each feedback data of send out carry on the only one marking, this is an important means that resolves the PV repetition  calculation problem and prevent°froms same customer to break to cheat for many times.

  The little wood tells the reporter, seeing from the result study currently, whichever edit collected materials superior can very easily control the Alexa tool return of data wraps the medium secret, if this person is a network  plait distance also superior, want so to cheat to Alexa more easy.Cheated the superior to gather news to an Alexa of Shanghai afterwards from the reporter to see, the little wood's analytical complete exactitude.Should cheat exactly an experienced Web of to develop the engineer, the means that it adopt is also basic with the little wood's analysis to fit together- the plait writes an Alexa  tool to return the born machine of code, the code string that the batch quantity creation Alexa can recognize, then sends back the data.alexa.com with the way of the virtual multiuser, can cheat the Alexa server thus, let it mistake these datas for the different customers to deliver of.( advertise for should cheat oneself approval, this special subject is in the end public reporter with should cheat net up chat factual records)

  The little wood think that this kind of imitates the multiuser to visit with the plait  distance method of cheat the way of realization, the most important link lie in to that Alexa uses to come to the only one marking  customer body of the born calculate way of the ID number break the solution, this need the calculate way analysis to enough many Alexas the tool carries on smell to explore, grabbing at its data to wrap to carry on the fixed amount.But the little wood also points out, these work for a plait distance superior to say, really not consider as what, just end the realization that cheat still needs to imitate a procedure with born enough quick ID number, this may be more difficult, however estimate according to the little wood, the domestic cans make the person of these affairs not in the minority, just this  superiors in the sons of Internet just seldom BE.

  See from above technique analysis, the Alexa the work server do everyday is to receive the data that global customer send back to wrap continuously, those more than ten parameters withdraw among them also write in the specialized database, then carry on the analytical calculation to these datas that that very day collect at a certain and particular time, and renew the website of that day to rank with the new calculation result.Observe according to the reporter, the analytical result of this database will keep long three years at least, because rank to change most datas varieties that can provide three in the last yearses in the trend diagram to the Rank of each website on the website of Alexa.

  After breaking to solve the DNA of the tool, the reporter returned to inquiry into the Alexa tool with some friends at the world of distribute the circumstance.According to the Alexa parlance, the tool is its only one information to obtain the source, so the tool is in global customer of distribute and also becoming the another can affect important factor that Alexa rank.If the tool is really the only one source of the data of Alexa, can imagine, the in the middle country netizenses did not install the time of the Alexa tool, the new wave search such gate website of fox to all can not see the shadow in Alexa rank perhaps, but this year is since second half year, new wave and search the position that the fox have already closed on the heels of the Google row in global fourth and the fifth, this explained that the Alexa tool has already had the higher universality rate in China apparently, otherwise, new wave, search the fox and close on the heels of to capture the Alexa afterward global 500 strong in near 1/3  Chinese websites of the quotas the suspicion that all have already cheat.

  Happily the reporter's a friend the 曹政 provides to make the delighted data of person.Be the website discharge analyst, the 曹政 is on the www.tong123.com for amount to 2000 more local and each kind of websites to provide the long-term discharge monitor and covariances to analyze the service.The discharge analysis of the 曹政 and the dissimilarity of the Alexa, Alexa not at the website that was monitor up do anything, but the tong123.com carries on the method of 嵌 inside the page to the website the third square the discharge statistics.Be subjected to the reporter entrust, the 曹政 is in the monitor that it joined in the data sample  analysis machine to the Alexa tool at the time.Through a week of data covariance, the 曹政 get the conclusion of is:Visit in all customers of 2000 websites of the www.tong123.com system monitor, the gearing rate of the Alexa tool is or so in 1.5%.

  Before send report, the 曹政 returned to reporter the hair came to this result of complement explain, he think, because of the calculation method that the tong123 the system adoption total amount was worth equally, the actual gearing comparison of the Alexa tool should compare the data get now higher, because this monitor the item just adds into soon.

  Because the tong123.com monitor scope is 2000 each kind of websites, expeling basically because of the monitor object the customer that the less may result in choice tendency, its credibility is higher.Even with 1.5% this gearing rate that was underrate to measure the Alexa in local customer of influence, also already very astonishing, if local Internet customer with amount 90,000,000 calculations, then among them installed the customer of the Alexa tool may already over 1,300,000.According to 10,000,000  download total amount in a world of or so tools that Alexa declare to see, Chinese netizen to Alexa of bent on seem to be more outstanding apparently, this can also be probably this year local website whole in the ranking of Alexa rank an elevated explain.

  Now that the tool distribute the meeting from the very big degree is up the influence Alexa of monitor result, so the Alexa ranking is for the very big region relativity of possible emergence, if definite such, Alexa authority really worth it doubt.The affair has no far so simple, on the website of Alexa, the reporter sees the global website ex-100,000 offer of ranking is USD 499, obviously, at the ocean the other shore, still someone approves the Alexa to rank the data, even will spend money to buy that seniority data.

  Unnecessary technique privacy

  In the Alexa various public data or the net friend's discussion to its, all no one puts forward the Alexa definitely in addition to the tool whether still is other can obtain the monitor means of the male net discharge, but long-term for the little wood who a website of several 著s provides the technique support, pass the daily record analysis to these websites, think plenty more technique privacy of Alexa.Because can't get the Alexa official response, we have to say that the technique means that these possibilities is adopt is" unnecessary".

  For further exploring the Alexa privacy, we still want to see the process that Web browse first.When the customer opens the browser of IE, after address input a string of Web address and return to car in the column, some datas that included the http claim wrap disheveled hair send out to go to, similar to other discharges, these datas wrap to also want through the net passes of the net inside the customer place, drive road from go to the male net, through a telecommunication engine room, end deliver a certain provide the server of the resolution of DNS up, in acquiring the addresses of IP of the purpose Web address after was again put first can with end road from going to the purpose IP of path transmission in the past.Request from the http of sent out the process to see, if the Alexa analyzes the server to carry on smell to explore to global ll DNSses, will get probably a near to the factual global http  claim data very much, can delineate very clearly from here which websites drive which customers pay attention to.

  However, to smell the claim of http of explore the world, is almost an Arabian Nights to Alexa.Back 10,000, even the Alexa can grab at these datas, it also impossibly takes these datas as the foundation to carry on the calculating ability.But, the some" tremble to move" evidence that Alexa display when rank seem to at tell the people, in addition to the tool outside, the Alexa really has the suspicion of the usage other technique meanses.

  Summer in 2004, the little wood discovered that the website of Chinese Hong Kong ranks to appear the promote of abnormality, being like the thus small website of" Sun Daily News", incredibly can more than a lot of websites with big hinterland rank.Because the reason, hinterland and netizen of Hong Kong of the telecommunication net pass and Chien the traditional Chinese system generally not do" across the region to visit with each other of", and the netizen of Hong Kong installs the absolute number of the Alexa tool also not higher than the hinterland customer.Formerly the analysis of the text and calculation to see, the gearing of the Alexa tool measures in the hinterland netizen perhaps aller not low than the quantities of the netizen of whole Hong Kong, under such circumstance, the website of Hong Kong ranks widespread and significant to promote and then seem to be to make no sense in the Alexa.

  Through two months of high rank the period after, the website of Hong Kong ranks to drop gradually in the beginning, but up to now still have parts of websites to rank the high it is physically should the position of the place.The little wood think that the circumstance that this phenomenon and Korean websites appear in 2003 have likeness very, but a lot of websites of Korea still have to rank higherly currently.If this kind of phenomenon use it is unreasonable that the universality rate of the Alexa tool explain, but if increased the parlance of other sample machines with the Alexa to explain, say very easily.

  Predict according to the little wood, the Alexa possibility established some sample machines in the global different place, passing to carry on with some telecommunication organizations or clear or dark cooperation, even carry on network's smell to explore in the node of the close by telecommunication  net pass, get some sample datas of" make up sex".But look for the purpose of these samples data exactly is for the sake of the care Alexa think of the sampling result of" a low gearing rate of tool" region.Beat for instance, if the Alexa thinks that the Korean Internet is already very universal, but the Korean customer hases been didn't habit that install the Alexa tool, it may try to find job for some sample machines in Korea, to make up in the shortage that Korea use a sample of tool.The circumstance of the same, also may cause Hong Kong while just establishing to sample the machine the website ranked fierce to increase.But the investigation of the process a period of time, the Alexa will adjust the sample quantity in each region gradually, to get the most reasonable result that it think.

  Even the little wood also thinks, the website of the hinterland ranks large-scale to promote to also have the sample machine this year at play tricks, but great occasion of nation after the hinterland website ranks widespread to descend perhaps be because of Alexa at through a year of investigation, re- adjusted to sample the result of the specific weight in the Chinese hinterland.

  Certainly, the Alexa wants to support the authority and candors that it rank, not only wanting the sample process of the perfect discharge data, but also wanting to do in the aspects of prevent°froming cheat a huge effort, those techniques that defend to cheat are all also an Alexa not the 秘s of the 宣 .So Alexa exactly is to use what way prevent°from cheat?In fact, for ex- text the reporter speaks of with the plait distance to imitate the Alexa tool to return the data to wrap of cheat the way, the Alexa is almost the good way of nothing important to guard against, even wanting to probe in to cheat the meanses thus all more difficult.

  In fact, cheat the means familiarly to the net of now up, the Alexa all have already had the enough immunity dint.Generally speaking, can't handle the script of JS because of the most manhunt engines of now, so usually aim at to search the engine to cheat is all to use the JS script the plait writes the malice code to carry out, but the Alexa and Googles adopt of then crawl along the procedure only can identify this kind of procedure of the script of JS currently.

  The little wood is in to the discharge monitor of a few large websites detection, the Alexa was in use a robot procedure that is called the IA_Archiver, similar Google of this robot procedure etc. the spider procedure of the manhunt engine usage, crawl along on the Internet exclusively, detect the discharge information of each page of Web.While ising a discharge that is a certain website to exceed the 阈 value of the Alexa enactment particularly, the IA_Archiver will climb the server of that website right away, whether the discharge of analytical this website is normal or not, have to cheat the behavior.According to the little wood's monitor to the IA_Archiver, the robot's procedure hases already can identify the big part to cheat the behavior according to the discharge that the website server carry.But the industry of now inside to widespread shortage of IA_Archiver cognition, the reporter also just sees the simple introduction concerning the IA_Archiver robot procedure on a help page of the website of Alexa, but the domestic know that the person of this robot procedure is not much, even lacking the related technique research.

  Trust the Alexa?

  Aim at the credibility that Alexa rank, the different person has the different viewpoint, being engaged in the Web technique research and applied industry insiders to incline toward thus a parlance more:The Alexa rank is not necessarily absolutely accurate, but is opposite and authentic.Underneath some examples that reporter enumerate, will never together the aspect carries on the contrast to the credibility that Alexa rank.

  Must admit, though the Alexa uses the usefulness that a lot of technique meanses raised the website discharge  monitor data, because of its proper some minor faults on the techniqueses, difficult do not need to make a handful of websites rank the result to appear some problems, though these problems want to blame on to a large extent the website area is unsuited to the reasonableness structure.

  For example, the Alexa rank is to aim at the address of URL, have no factor of consider the address of IP, this lowers the Alexa to rank the calculating difficulty to a large extent, but also produced the deviation inevitably.Generally speaking, the Alexa is interested in the second class area only, but aim at the discharges of the x-rated area to all is brought into last one  covariance of the class area, for large website but speeches of the comparison norm, this is the complete right strategy, but toward the website that the different customer distribute the x-rated area for a say, its discharge statistics whether should add all discharges of sub- customer?This obviously the important cause circumstance but different, a very obviously this kind of example of not reasonable covariance is a cninfo.net, believing that local and old netizens all still remembers a suffix of this area, this is national and each city  public information harbor  in general use second class area, for example, the sh.cninfo.net and gd.cninfo.nets are two websites of Shanghai and Guangdong respectively, but the son area that Alexa then unifies it to do the www.cninfo.net on the whole.Hence, the www.cninfo.net becomes the simplified Chinese character website to rank the website of more than 40s, though it is not a website that can visit in fact and basically.

  Rank the credibility for the Alexa of another a kind of huge difference of the discharge characteristic that queries to come from the different type website.For example, the discharge of the gate website and professional website or professional forum almost have no and be able to compare sex, because the customer of different type when the not meantime different situation visits the website of different type, it browse the habit and there will be the tremendous difference.

  Even two websites get the comprehensive discharge of  valuation value according to the calculate way of Alexa complete homology, that also can't row the mark of equality to two influences of website.For example, a Reach is worth to 1000, the website that PV is worth to 1 is worth with a Reach to 100, the Rank of the website that PV is worth to 10 should be same, but under big and parts of circumstances, the contents of the latter will compare the former to even have the value.Because browse a customers of websites are all to see a page walk off only, explaining the possible nothing important attraction of that website;And then a customer of website wants to see ten pages would leave equally, these customers all approve the contents of that website very much.Certainly, the more extreme circumstance also will appear, for example the former onlies have a page, but the page's contents is very abundant, and then each page contentseses of are few, or established for customer a lot of otiose jump to turn, even the latter also may be a novel to serialize the station.

  The existence of these complicated circumstances can hardly let person believe that Alexa can only use the Reach and PVs these two be worth and then order all station on the Internets to divide the line 369 etc.s of.However, if we change an angle to see the Alexa, will discover that its existence also is to have the reason, even also likely to be definite worthy of netizen trust.

  If we consider as a discharge  analysis service tool to the Alexa only, its value was convex to appear.Provided to keep the discharge variety  trend statistical chart function of view very much on the website of Alexa, this wants to pay the service that then can acquire under the condition of many other, but Alexa be just be it free public service.

  Figure 1 is the Alexa provides up of account one in the last years of a life time net( ccw.com.cn) of discharge rank( Rank) the trend diagram, from the diagram can with see clearly, that website November 3 in 2003 ～ November 3 in 2004 rank from 7500 or so rise to 2000 in, but three among those timeses descend the curve very suddenly to should of date is the Chinese New Year,51 and 11 se three vice-ministers respectively false.Know to all, account the main concentration of the customer of a life time net in the profession of IT, these three vice-ministers are false to cause of descend the curve to minute down the then netizen to browse the circumstance very faithfully- because have a holiday, most customers travel or take a rest at home, get to the Internet the customer reduces consumedly, so the discharge lower, the website ranks to also lower immediately.But the long leave is later on, the IT person returns to the unit, the first day go to work total will thought of that the net goes up latest information of see the industry.So the long leave is after, the ccw.com.cn discharge all compares on the contrary before have a holiday had the different degree to promote, reflect on the curve of Rank, after is three big trough of waves curve height of instauration with increase continuously.

  In fact, if can the trend of the detailed analysis  website discharge variety, the people can also distinguish one those cheat of website, because usually cheat the variety of the website discharge the right and wrong is normal, it with the discharge variety curve of the normal website the affirmation contain different place.Figure 2 and figure 3 is a 265. coms and dsdiy.com half a year-old discharge to rank the trend variety diagram respectively, the 265. coms are the Web addresses of the local of 著s to navigate the station, the world of the recent half a year always rank stable at 70-120 in.Look back the dsdiy.com the Rank variety curve rather worthy of doubt, September the first week, that website rank from 100,000 of world outside on jumping to go to 200 or so, afterward of in a month, that website always rank at 100-400 ofs go back and forth, but in the great occasion of nation long leave the first day, that website rank unexpectedly the 蹿 rises to go to 30 or so, October the second week, that website rank again quickly drop to 100,000th open the outside, canned not see any further on the Rank curve diagram, the website that owns to is similar to rank the curve still has the sinapet.com and the haohz.com etc.s.

  Be the monitor tool of the Web interview circumstance, Alexa at the time of recording the true interview quantity of website, also recorded those the discharges variety circumstances that cheat the website equally.Say up from this meaning, the Alexa also is authentic obviously, the key is the angle of view that we choose must the ability just right ground develops the Alexa of function.

  Proceed from regardless what kind of purpose, the people betray the Alexa to always hope to get the benefits from it, to the Alexa research more thorough, have to be more deep to the Alexa worth comprehension, can benefit from it more.

  A:The core is my, still having a few friend helps, we are from 2002 meeting this.

  WANG2 YI4:You had to try, does the best result for can make is how?

  A:Now I can chase a website maintenance that have no discharge at probably 50 or so, this is the extreme limit.However general we will not make a mess of.And also a so high price to hire we do so high, we according to rank high and low to charge of.

  WANG2 YI4:Support these websites rank would more and more easy?Because do they go up hereafter, can the discharge really increase?

  A:The customer is all the advertisement generally to do with us together.

  WANG2 YI4:Your meaning is they at the time of pull highly rank, also do the website expansion?Still say that they take to rank to pull the advertisement by themselves?

  A:Is the former, persons who be the website all know, the light have a rank falsely dull.The customer's mindset is in fact easy, they did the advertisement, true person's spirit will go up, but not necessarily rank and will go up.

  WANG2 YI4:So, does the Alexa just promote another method of the brand?

  A:Their  money flower is on the advertisement, a money flower is in our body, thus two enters also, waiting the discharge to really come up some, ranked to also do up, they connect again the advertisement easy.Advertise once the company see, rank quite good, come up to try for the hurl, thus they by themselves of discharge again really not too difficult see, advertise the company more easy approve.

  Weave the distance breaks to solve the tool to rank how much whole can control

  WANG2 YI4:The work mechanism of the Alexa tool you should know very much?Yesterday I saw break the code of the solution there at a friend, it was each time at the customer browse return a string of code, probably had 9-10 parameters in these codes, include the Web address and browse way what of, even the net can monitor soon.Is the circumstance that you understand thus?

  A:Is thus about, but that is not the net soon, is time that adds to carry the page.For example same page, you are in the native interview, is the very fast, you visit abroad, is a slow, so I feel that the Alexa give the Speed of this is unfair.

  WANG2 YI4:Can you discuss the method 么 that you adopt in a specific way?The as I see it, two basic parameters that Alexa rank, is also Reach and PVs, aim at what they are all to cheat, but the way dissimilarity of the realization, another Alexa also have some meanses that defend to cheat, does how you are fix?

  A:Write the procedure.

  WANG2 YI4:Break to solve the tool of Alexa?

  A:To, all don't pack the Alexa tool on our machine, this trick is again slow again the memory leak, annoyed.We are emulators that writes with the language of C under the FreeBSD, can affect two values of Reach and PV at the same time.

  WANG2 YI4:This emulator is on one  pedestal machine imitate at the same time many person on-line visit the website?

  A:Can say so.Broke to solve its calculate way, can imitate many people.

  WANG2 YI4:A the pedestal machine that you do can imitate how many the persons' interviews?If want to be a website from did not have of attain 100, need to be use how many resourceses?How much time?

  A:Forgive and don't inform, anyway is to imitate many person's interviews.

  WANG2 YI4:Does the way of this kind of virtual multiuser interview has the memory very much?

  A:O.K., is mainly resources that wastes the CPU, however the FreeBSD is enough sturdy, if under the Windows can tired.

  WANG2 YI4:Is main to is compute by CPU a great deal of camouflage Alexa return the code, then have the enough bandwidth only to give send back to go to all right?

  A:To, but the bandwidth is not a problem, at least at I am here have not yet become interfering with, say the white the most important is still the calculate way of the emulator realization.

  WANG2 YI4:I saw there from the friend of seem each code string also 10010 come to a word stanza?

  A:To, so say that bandwidth is not a problem.The CPU is in fact general of also went, do not be very bad, run by the line distance.Have 23 customers to seek the affair that I talk over to buy the technique directly, however the price is too low I did not agree, they also despised this technique and its gold contents too.

  WANG2 YI4:You follow two years of Alexa since, the tool return of this code of calculate way rule, does the Alexa have to change the 么 ?

  A:Onlied have the pimping fluctuation.

  WANG2 YI4:Does the October of this year have to change once?Seem the local website is widespread to was subjected to spread to.

  A:It modified two powers of parameter heavy, increased the PageView power heavy.So those are pure to pull the discharge by beating the advertisement, but oneself stay again not the website of live the customer suffered a los, such website although the discharge may have the exaltation, the PageView is not high, the customer that is advertise to draw on to come over sees an eye feel dull, the possibility jumped to turn the another website right away.

  WANG2 YI4:So you know the calculate way formula 么 of the integrity that Alexa rank?

  A:Concrete how to calculate, only have the Alexa to know, but it affirms to hope that this calculate way is reasonable, so it also would according to some cheat the means familiarly to adjust its calculate way, this kind of way that we use breaks to solve the tool directly, unless it gives up a technique of tool of now, otherwise still taking we have no way.

  WANG2 YI4:In addition to the tool, does the Alexa rank to still have other basises?

  A:Now what people know be the tool, the Alexa seem and also did not say to still have the another way, so only the ability is the sampling data.Usually someone say, the independent IP of our website rise so many, why rank to decline on the contrary?I tell them, having two reason:1, the independent IP did not represent to pack the interview customer of the Alexa tool to increase much;2, calculate you much, the other people are perhaps more, ranking to relatively come out each other.

  Cheat to also have the principle to drink water and can't forget to dig a well

  WANG2 YI4:How many customers did you connect now?

  A:We generally can't the confusion BE of, still doing also now not over 5, very careful, but seek our person always quite a few.

  WANG2 YI4:Is all to request to attain 100 or so?

  A:Also is not, also have as long as beg more than 2000 of, such customer is very rational.

  WANG2 YI4:What is the principle that chooses these customers?Is rich and then go the 么 ?

  A:Is not, some small website, on come will we attain 100 for it, this kind of we do not connect.

  WANG2 YI4:Have too high request do you  not connect?

  A:Isn't a request too high, I want to want to do and can also attain, but say a truthful story, we are Alexa parasites, also would not like to once own" host" to made to die.

  WANG2 YI4:Also want to speak the strategy?

  A:Yes, have a customer last time were grieved by me.The 呵呵 , a MM, I said once to have to keep too at that time, saying that the garbage website want to be so high to rank why, she got angry.

  WANG2 YI4:Can say thus, the net had 5 Alexas of website to rank last now is you are support, and all at 100 following?

  A:Is, have to rise 100 websites of price few, basically what I do is 300-1000 or so.

  WANG2 YI4:How much are 300 prices?

  A:8000 of every month.If the object is 300, that is 300-400 in fact to float, WANG2 YI4:This price is to some small websites also not low.

  A:Small website with what arrive global 300?

  WANG2 YI4:Seek are you all a big website?

  A:Is qualified for at least.Some small website as long as beg 10,000 or so, this kind of business we are again lazy and have to connect, unworthy do.

  WANG2 YI4:Your request to them is what?

  A:Is this website to still be like an appearance at least, and have to rise this money.Also had a customer to do a month only, because the server was attackstoned by the black guest a burst of, rank to fall very miserably, seek me to do a month for them, save to come back from lose.

  WANG2 YI4:But you are a not to do after month, it not is to drop to return again a lot of?

  A:Not, that website because still have the good customer foundation, discharge also always at back up slowly.They just need me to rank to save back equally the degree of quarter that they lose.So I need to change strength for them everyday, the way that use to change gradually, thus the other people are also not easy to see out is someone at help them to cheat.

  WANG2 YI4:Your way can think that how to go up how to go up, even can control the rhythm, is a 么 ?

  A:Yes, before can't, improved afterwards, because customer's request also at raise continuously.

  WANG2 YI4:Whether thus, that month the function that you start rise is more and greatly, hereafter reduce your function gradually, and that website oneself the discharge of the instauration start to be gradual since the function, arriving the end of the month, even you do not do, did the discharge of their website oneself is also basic to recover about?

  A:To, such words, that website is in the curve of Rank on the Alexa in this month more even slow, the person who have no knowledge basically cans not see clearly, only can see they is attackstone that several days to rank to decline suddenly, then recovered right away, in fact that process that recover long month.My function be let that website of the degree of quarter is total to rank equally uninfluenced.This kind of website that has the real strenght, I am not to do, a still can recover to come over after month of, just because this month rank all lower, will cause continuous degree of three quarters of month total to rank equally not good-looking.

  WANG2 YI4:Does this kind of website that has the real strenght also care the Alexa to rank the 么 very much?

  A:Care very much.

  WANG2 YI4:Why?

  A:I raise an example, you do a website, following to advertise the company to say, my website spend the good 稻 good, the somebody else go to the Alexa up on check, originally your website rank so low, who still believe you?

  WANG2 YI4:However the Alexa the tool really pack in local customer actually and not much, seem to to the local website thus very disadvantageous.

  A:Already several came now, believe it or not.I controled this technique in 2002, but also just start open this kind of business of exhibition this year of, because the Alexa just start being subjected to the value in the domestic in the near future.

  WANG2 YI4:Does the local website that you know cheat what?

  A:Seek my person a lot of, local and a lot of websites all in dry this kind of matter, but the skills that cheats are all not high, understanding this person from the Alexa the history curve diagram in can analyze out

  The dear website  CEOs, hello, everyone!Today this stanza lesson, I want what to speak is, we how betray the Alexa.The way that betrays the Alexa have a lot of, be like me to spend time thus to study it an an an an an an an an an an an an a week, then write one ten thousand  speech books of with one more time of weekend, waiting for to see turn carry the rate after needing the newspaper publication, the end earns only some son spirit comforts the prize of old soil, still reach obviously not to arrive the purpose of betray the Alexa.

  But the more brilliant than me person have plenty of!Particularly on the Internet, is the this website CEO past that you can't know to sit at the same table an a dog, O.K., had the Alexa ever since that time, your a lot of went together to all gain both honor and riches.

  Go back to the subject, would not° what to release is teacher WANG2 to cross mountains the mountain to wade across water to turn over the mountain more 岭 studied the innumerable after cheat website tally up the precious experience of a little of below, also not the consciousness denies to sell some son  copyright fee.However for the sake of we this school clicks the quantity, also having to endure first!The website that waits the 咱 entered the global TOP10 of Alexa, cheating the US$ of the investor, tidy up the guy of this pirate edition slowly again!

  Long two years of observation and analysiseseses are after, I think, to betray the Alexa, as long as complete following three stepses in order all right.

  Square one, you want to be first friend of become the Alexa.Or say, you must let the Alexa become your friend, at the same time on the face of it you also have to express by yourself seem the Alexa friend.Then, have already become the friend of you must build up with Alexa mutually the trust of.Certainly, let oneself the trust Alexa want to compare to let the Alexa trust you to want far and have to have another easily, occasionally doing the once mental allusion to go, inviting everyone to recite below with me together and in mind:" Alexa!Alexa!Alexa …… "

  Let Alexa produce to you trust definite have a little troublesome, but I am through detailed research, still finding out a can believe but viable way.When you hope that another person trusts you, but you basically can't cause the time of the other party attention again, onlying have a way, is an outlet that build up a trust's deliver.Say the white, is to find out a the third square, this the third square is to trust your person, is also the person of the Alexa trust.Use this kind of way, can obtained the Alexa to trust with the indirectly.

  To this usage, the website  alliances are all superiors, original who also incognizant you, suddenly and one day, you was lead into a son, inside of person all know each other, you want ～only a person of understanding enough, after you join this son, very quick can obtain inside the trust of the owner.This sounds to have a little the son to be like black help, however when the discharge of your website start 100 meters sprint because join such alliance, you will not care this son to have many black.

  The second step, be you and Alexa after obtain mutual trust can prepare to betray the Alexa.Notice!This is just the phase zero, but this one step will decide you directly end betray the benefits that Alexa can acquire!

  At the time of this one step end, the result that you need to see is, the prestige of Alexa is very high, and it want to be enough high with the evaluation of your friends also to you.Say keep the view some, be you and should your friends become the Alexa of the Fans and the agent.If you are a website that has the real strenght, should consider the hurriedly means of usage, for example, put the breeze on the medium, aggrandize the Alexa everywhere, then suggest another information to medium in the fitting opportune moment:My website rank early in the TOP500!Best way that examines this one step to carry out the result be in the checking to seek the Alexa and your website at the same time in the news manhunt of Google of name, this result is more many, this one step complete more good.Who complete the deployment of this one step first, have confidence to give Alexa to pack to sell.

  Like, we say the key one step of the end now, exactly with what way betray the Alexa, this one step will test the performance ability that you be the website CEO well, if performance like, you can become the next D 磊 , if performance bad, you also can become a dog of the Internet only, making not to like to still fall into water the dog!

  For contacting with the theories betterly physically, underneath I want to adopt a teaching method of case.See the most successful example first-" escape the net", worth everyone's heart of this website past knows that the belly is clear, but the Alexa of now think that it is the eldest brother of the local C2C.It betrays the means more brilliant, find out a sole agent first, this sole agent underneath has a flock of small website to act for again, although the discharge of the each small agency is all not high, the total generation know the exploitation human wave tactics of warfare, and China make the planned parenthood night 10 years, this the total generation was light to become the global biggest discharge business agent loosely, the price code is very high!Escape the net back to still have a 阿 luckily in father, changed the other people, return the true 掏 and don't rise so many silvers!

  With escape the net to compare, the tapeworm net has a little the son depressed, the COO of this website was very not easy to think a way, launching underneath several thousand tapeworms to betray the Alexa at the same time.Regrettable, so many tapeworm, difficult do not need and there will be is dissatisfied to the boss, the result Alexa did not sell to go to, the boss of the tapeworm net is first drive own employee to sell!This hangs the case to still have another parlance, because there is 阿 in the letter of that tapeworm  net COO of the medium announcement in father's name, someone is for the guess, this is the 阿 in the persecution of household to the tapeworm household.Regrettable, have no proof!Be like to escape the net so, who all think it cheated, but who also could not take the proof!Who can thought of that rank at escape the net underneath of website alliance incredibly is escape the net of sole agent, but a flock of rank from 1,000-100,000 not the small websites that waits are all its underneaths of outlet?

  Good, is the here today, hope that each CEO  classmate lesson descend like to like to want, develop your intelligent wisdom and ability, study to betray the Alexa way more thoroughly.End again free send you a maxim:Betray when it's necessary to betray, do not take care of the discharge to is much bad, go forward an is a, never fear to stay to scold.
