Expanding the formula X - index of the quality of the site Yandex

On August 31, Yandex replaced the accustomed CY (thematic citation index) with an incomprehensible X - site quality index.

Justifying the name of the new indicator, Yandex does not disclose the formulas for its calculation, limiting itself only to general phrases that, in determining the quality index, all information available from Yandex is used, obtained from its various services.

What do we have to do? That's right, do research and get to the bottom of the truth!

The study was based on data from 705 largest forums of Runet, Uanet and Bynet. Information about the forums was obtained from the ForumRate.ru forums rating .

X and TCI

To begin with, the most logical would be to compare the values ​​of the X with its predecessor TCI.



As can be seen from the graph, no connection between these indicators is observed. So, Yandex was right: the era of SEO links is over, you need to focus on other indicators. But which ones?

IKS and Alexa

Alexa.com with the help of the toolbar determines the most visited Internet sites and builds them into the ranking. Thus, Alexa ranking is the position of the site in terms of traffic throughout the Internet. The lower the number, the more popular the site.



And here we see a correlation between IKS and Alexa! Thus, we can conclude that the rating of the X depends on the attendance of the site.

To test a guess, let's turn to statistics LiveInternet.ru ...

X and LiveInternet

One of the LiveInternet.ru services is the attendance counter. Of the 705 forums participating in the study, 311 (44%) have an installed and running counter LiveInternet.ru.



The above diagram confirms our guesses: X is directly dependent on site traffic.
