Alexa rankings despite a lot of controversy, but in the absence of better tools, is still our measure of a Web site traffic status and influence of an important indicator, the most friends around the issue is the Alexa authority and algorithm elements.

Alexa rankings authoritative

On the issue of authority, in fact, there is not much to discuss, according to the sampling algorithm, if the Alexa toolbar installation rate is certain, then no matter for any site is relatively fair.

If the Chinese region of the Alexa toolbar installation rate of 1.5%, portal a traffic of 100W, Portal B traffic is 300W, then their Alexa visitor rate is generally in the 1%-2.5% between the fluctuation, so the comparison out of the ranking is correct, And according to the statistical algorithm, the number of sample samples, the more the statistical results are closer to the real, so the general ranking of the former site relative to the real higher, popular point is that the ranking of 100W to 1W and ranked 1W to 100 of the difficulty is not a level.

On the Alexa ranking authority has been a huge controversy, and even someone Chenge to abandon Alexa rankings, the reason lies in the gray area of the Alexa rankings cheating, as long as you are based on the Alexa toolbar sent data ranking calculation, then ranking cheating becomes possible. Although the Alexa will be based on the relevant needs of the filtering of garbage data, but there are inevitably slip through the cracks. Even the internet two major portals Sina, Sohu has been trapped in Alexa rankings cheating door events. This phenomenon cannot be completely eliminated, but can be adjusted to optimize the algorithm to obtain a relatively real ranking, which is the following issues to be addressed.

The algorithm improvement of Alexa ranking

Alexa.com on April Fool's Day (April 1) The new version of the line is not what news, but relative to the interface of the improvement I personally pay more attention to the algorithm part of the substantive changes, after two months of observation to have some things to share.

Alexa before the release of the new version of the change in the ranking changes too large, even one night heaven not too much to describe, this is the Alexa test it's new algorithm, when the next Alexa new version of the official online when another exclamation, the following said some specific personal ideas.

Alexa new version began to introduce more ranking elements in order to achieve a more authentic impact ranking, please note that I am not talking about traffic rankings but impact ranking, which can explain why a lot of traffic amazing novel station is not necessarily able to get and traffic matching rankings.

These elements may include social bookmarking, search engines, external links, traffic sources, export traffic, it is noteworthy that although some of the data is still from the Alexa Toolbar, but does not exclude Alexa from the third party to buy or exchange data, these third parties may include traffic statistics and some social sites, Relatively speaking, they can show the popularity of a website fairly.

Now I blog Alexa comprehensive Ranking is 30W, the recent average ranking in 20W up and down, you can guess to my blog traffic is how much? The results will certainly surprise you, my blog traffic is only floating between the 100-300IP.

To be able to get such a high ranking I personally summarize the reasons: 1. Original articles can get more attention and external links; 2. The content of the blog to it,it People's Alexa toolbar installation rate will be higher than the average user; 3. The article is recommended to some well-known websites, Can be understood as a site recommended sites should also be a good site, you can give more rankings weight.

Mouchangqing once wrote an article "Why Webmaster category site Alexa rankings all red?", the discussion is also about the ALEXA4 month algorithm change topic, I quote his article of that form.

From the table can be seen, there are some of the rankings of the site has not been able to change the size of the Webmaster Alexa toolbar installation rate of high to explain, these sites almost everyone is very familiar with, this can also prove that Alexa is more inclined to show the real influence ranking, but not only the flow so simple.
