Yandex.Radar shows you how people use the internet in Russia and other countries

Reports on search engines and internet technologies

To calculate the market share of search engines, browsers, device types and operating systems, we track what percentage of site sessions they have provided in the total traffic in the region. To do this we analyze summary data for Yandex.Metrica tags. Reports on technologies and search engines are available for four countries — Russia, Belarus, Kazakhstan and Turkey.

Statistics for the share of search engines and browsers can be seen broken down by operating system and device type. For example, you can compare the share of Chrome Mobile browser on iOS and Android or on tablets and smartphones.

Data source

Yandex.Radar uses the aggregated statistics from all sites with Yandex.Metrica tag installed. Yandex.Metrica is the leading web analytics system in Russia, launched in 2009. As of August 2018 the system registered 78.88%* of the overall .ru domain traffic. According to W3Techs, Yandex.Metrica is the third most-used traffic analysis tool for websites in the world.

In order to provide accurate measurements, we exclude sessions from all Yandex sites from all Yandex.Radar reports. The data may also be adjusted for inaccuracies that appear as a result of various technological changes. For example, during global transition to the https encryption we introduced a correction to compensate for some older browsers losing referrers of the traffic from HTTPS to HTTP.

Traffic is measured in sessions. The geographical origin for a session is determined by the site user’s IP address, while the session time and date is provided by the tag’s set time zone. Meanwhile, the user’s browser, operating system and device type is found via the User Agent string. The search engine is determined by using the same principles as the “Search engines” report in Yandex.Metrica.

What is a session?
A session is a sequence of actions performed by a single user on a site that has Yandex.Metrica’s tag installed. Page views, clicks on external links, file downloads and other types of site interactions are factored into a session. A session begins with the user’s transition to the site and ends when the user is inactive for a certain amount of time (30 minutes by default). However, tag owners can set their own inactivity time limit. Learn more about sessions in the Yandex.Metrica help center.

Yandex.Radar reports for search engines and browsers contain statistics starting from January 1, 2015, while reports for operating systems and device types start from April 1, 2015. You can choose any date range for analysis up to the last seven days.

Top Yandex Projects

Projects included in Top Yandex Projects

The Top includes Yandex projects that are ad sites. The project site and app (if any) are treated as one project.

What traffic indicators are

We use cross-device matching to measure the monthly and daily audience of a web project. This lets us "recognize" the user on any browser or device. For example, if the same user first uses Opera and Chrome from a desktop, and then Chrome on a smartphone to open a site, one cross-device user is added to the statistics. That's why with cross-device matching, we don't overstate the site audience, unlike counting unique browser IDs accessing the site. We use Crypta to match the anonymous browser IDs and device IDs of the same user.

"Average time" shows the average time that a cross-device user spends on a project per month. "Daily audience" means the average number of cross-device users per day over the current month.

"Percentage of app users" shows the percentage of app users in the total cross-device audience of the project.

How often we update Top Yandex Projects

The monthly report is published on the 10th day of the following month. For example, the July report is published on August 10.
