Alexa ranking authority and algorithm elements

Despite a lot of controversy, the Alexa ranking is still an important indicator for us to measure the website traffic status and influence without better tools, the most talked about by friends around me is Alexa's authority and algorithm elements.

Alexa ranking authority

There is not much authority to discuss. According to the sampling algorithm, if the installation rate of Alexa Toolbar is certain, it is relatively fair for any website.

Assume that the installation rate of Alexa Toolbar in China is 1.5%, Portal A's traffic is 100, Portal B's traffic is 300, in this case, the visitor access rate of Alexa generally fluctuates between 1% and 2.5%. In this way, the ranking is correct, and according to the statistical algorithm, the more samples are sampled, the statistical results tend to be closer to the real ones. Therefore, websites with higher rankings generally have a higher degree of authenticity, in other words, the difficulty of upgrading the rank from 100 to is not the same level.

There has been a huge controversy over the authority of Alexa rankings in China, and some people even call to abandon Alexa rankings, because Alexa rankings in the gray area are cheating, as long as you calculate the ranking based on the data sent by Alexa Toolbar, ranking cheating becomes possible. Although Alexa will filter junk data based on relevant needs, it is inevitable that there will be net leaks. Even Sina and Sohu, the two major Internet portals, once fell victim to Alexa ranking fraud. Such a phenomenon cannot be completely eliminated, but it is completely possible to adjust the algorithm for optimization to obtain a relatively real ranking. This is the problem to be discussed below.

Improvement of the Alexa ranking algorithm

Alexa.com launched the new version on the day of November April 1, which is no longer news. However, compared with the improvement of the interface, I personally pay more attention to the substantial changes in the algorithm part, after two months of observation, we can share some things with you.

Before the release of the new version, Alexa experienced a big gap in rankings. It is not too much to describe the "heaven and hell" overnight. This is Alexa's new algorithm, when the new version of Alexa was officially launched, another alarm was triggered. Here are some specific personal ideas.

In the new version of Alexa, more ranking elements are introduced in order to obtain more real influence rankings. Please note that I am not talking about traffic ranking but influence ranking, this can explain why many novel sites with amazing traffic may not be able to obtain a ranking that matches the traffic.

These elements may include social bookmarks, search engines, external links, traffic sources, and exported traffic. It is worth noting that although some data still comes from Alexa Toolbar, however, it is not ruled out that Alexa purchases or exchanges data from a third party. These third parties may include traffic statistics and some social websites. In contrast, they can fairly reflect the popularity of a website.

My blog's Alexa ranking is 30 W, and the recent average ranking is 20 W. Can you tell me what traffic is on my blog? The result is certainly unexpected. My blog traffic only fluctuates between and IP addresses.

The reason why I can get such a high ranking: 1. original articles can get more attention and external links; 2. blog content focuses on IT. IT personnel's Alexa Toolbar installation rate will be higher than ordinary users; 3. the article has been recommended to some well-known websites. It can be understood that websites recommended for the big site should also be good websites and can be given more ranking weights.
