How sites end up in Yandex.Radar's Top Online Projects

Yandex.Radar automatically selects about 10,000 of the biggest online projects by the number of users from Russia. Any site with a top-level domain can end up in Yandex.Radar's Top Online Projects, not just .ru or .рф domains.

A single online project encompasses all the sites and apps using the same name. Data for app audiences is only included for projects that enabled sending data from AppMetrica

Where we get online project traffic data from

The rating is formed based on aggregated anonymized data from Yandex Browser, Yandex Elements, Visual Bookmarks, as well as from browser extensions and other Yandex products. By default, data from Yandex analytics services are not taken into account.

Various online projects have a different percentage of Yandex users in their audiences. This is why we create an individual statistical model for each project to calculate traffic using machine learning. It defines a range that is highly likely to include the actual number of resource users for the selected report period.

Next to the online project in the rating is its minimum traffic rating and by hovering the mouse cursor over this value shows you the upper limit of this range. The minimum and maximum amount of traffic are estimates. Therefore, their values are rounded to three significant figures. Online projects are ranked according to the lower end of the traffic range.

For a number of large projects, the most likely traffic value is shown instead of a range because there is enough data to make a more accurate calculation. Such projects include, VKontakte, Odnoklassniki, Facebook, Instagram, Google and YouTube.

VK, Odnoklassniki, YouTube and Instagram are rated separately from the internet companies they belong to (, Google and Facebook, respectively). This is because the domain names of these projects are different from the domain name of their owner companies. Similarly, the portal's traffic is not counted for the projects, and

For those online projects that don't have the Approximation label, exact traffic values are shown instead of approximate values. These projects have given permission for use of data from Yandex's analytical products in Top Online Projects, which is why their traffic is not calculated according to a statistical model, but according to data from Yandex.Metrica and AppMetrica.

You can connect to Yandex.Radar's Top Online Projects statistics from analytics systems via the link opposite the online project. This data will be used in the rating within about two days after connecting. If the online project disables the transfer of data, the data will also stop being transferred to Yandex.Radar after two days, and the figures for the past months will not be recalculated.

Yandex.Metrica data allows you to not only calculate accurate traffic indicators of an online project, but also to add new indicators to its statistics in Top Online Projects. For projects that have enabled transmitting data from Yandex.Metrica, the "Average time" and "Daily audience" columns are filled. In addition, such projects appear in the rankings by audience characteristics — Russian region, device type, income level, gender and age.

Using data from AppMetrica can more precisely calculate the traffic indicators, because they will take into account mobile app users who do not visit the resource. In addition, the percentage of app users in the total audience is shown for online projects with AppMetrica data connected.

What traffic indicators are

The traffic of any online project is determined in two ways: the classic method (via anonymous browser identifiers) and through cross-device matching.

In classical calculations, the number of unique users is equal to the number of unique browsers which opened the site. This is the most widespread method of calculating an online audience. For example, if the same user opened a site in Opera and Chrome from their desktop and then Chrome on their smartphone, three different users are counted in statistics.

Cross-device matching allows you to "recognize" the user on all of their browsers and devices. In the example above, Yandex.Radar will take into account one user regardless of whether modelled data or exact statistics are used. Therefore, when using cross-device matching, the number of site users is not overestimated. Crypta technology provides the ability to match anonymous identifiers of browsers and devices belonging to the same user.

The data from Yandex.Metrica tags that is used for calculating project traffic in Top Online Projects is standardized, so that sites are on equal footing for comparison. As a result, standardized traffic data in Top Online Projects may differ from data in Yandex.Metrica reports. The main causes of differences are:

— Yandex.Metrica saves data for site sessions from any regions, but only Russian traffic is taken into account when calculating the positions of Top Online Projects.
— Regardless of the settings of a specific Yandex.Metrica tag, filtering robots are applied to the data to calculate the ranking according to strict rules and behavior, while the session time-out is set at 30 minutes.
— If one and the same tag is installed on different sites, only the data for the project's domain will be used to calculate the position of that project.
— If the resource sends statistics from AppMetrica, the traffic indicators in the rating will also include data for mobile app users who did not visit the site.

How online projects are ranked in Yandex.Radar's Top Online Projects

Cross-device audience data is used to determine the position in the rating. Online projects where the number of users is calculated by the statistical model are ranked according to the lower end of their traffic – except in the case of a number of large projects, for which the range is not specified, but rather the most likely traffic value. For more details, see Data sources

Several resources with the same approximate traffic can be in the rating. This is possible as the interval boundaries of traffic are rounded up meaning that they are estimates and not exact values. Resources that have the same minimum traffic are arranged alphabetically. For example, will be ranked higher than

The "up" and "down" arrows next to resource names reflect changes in position from the previous month.

What are categories and types

"Type" is the functional purpose of the resource while "Category" is what subject the resource concerns. A separate ranking is made for each type, category and combination of the two. For example, an online store selling cat food can be ranked in the following ratings: resources about pets, resources about cats, online stores, online stores with pet products, and online stores with products for cats. A resource may have multiple categories, but only one type.

Types and categories are determined automatically using machine learning. You can adjust the type or category of a resource on request. To do this you will need to fill out a feedback form by clicking on the link next to the online project in the ranking. You can reach the link via the Settings symbol — ⋮ (three vertical dots).

Type descriptions

This type relates to bulletin boards for various types of classified ads, such as job searches and buy/sell/trade for items, services, real estate, or autos. It includes sites where users post their own ads (like Avito), as well as sites that automatically aggregate offers (Yandex.Market, Booking.Com, AviaSales). This type also includes news aggregators that don't publish their own content, such as Yandex.News and MediaMetrics.
Resources for downloading or viewing video content, such as online movie theaters. Some sites with video content do not fit in this category: sites of TV channels are considered "company/organization sites", and sites with erotic or pornographic content are in a separate category.
Online stores
Resources for ordering or purchasing items. This does not include aggregators of store offers (like Yandex.Market) or classified ad platforms (like Avito) — these resources are categorized as "aggregators". Sites that offer "offline" services (travel packages, cleaning services, and so on) are also not considered online stores — they are "company/organization sites".
Content projects
Resources with content that is sorted chronologically or by section. Content can be in any format: articles, images, Wiki projects, and so on. This type does not include directories with links to materials on other sites (these are "aggregators"), sites with content that is quickly outdated (these are "news"), sites where any user can create content (these are "communities"), or sites with videos (these are the "video" type).
Content is considered news if it is sorted chronologically and is updated at least every few days. This type includes news sites without a particular theme, as well as sites with a specific focus (like politics or finance). However, sites with news about a highly specialized subject (such as a specific computer game) belong to other categories — "content projects" or "communities". The News type also does not apply to aggregators (like Yandex.News).
Online games
Sites where you can play one or more games online. This type also includes the official sites of games, where you can download the app and the game itself takes place online (for example, This type does not include the sites of game publishers. For example, belongs to "company/organization sites".
Pornography and erotica
Projects with any content of this type: videos, images, texts, and so on.
This type includes the global search engines: Yandex, Google, and others.
Company/organization sites
This type applies to resources where users can place an order for an offline service. For instance, this includes travel agencies, banks, and internet providers. It also includes sites that sell items that can only be purchased offline, such as automobiles or real estate, as well as sites devoted to brands or manufacturers and official sites of non-commercial organizations.
Resources that serve a specific purpose. For instance, this could be services for listening to music online, storing files, viewing maps and weather forecasts, or creating and editing images.
This type is for communities devoted to a specific topic. These might include social networks, forums, blogging platforms, Q&A platforms, sites with user reviews, and other similar resources. This type does not apply to sites that have most of their content created by site admins, professional writers, or a limited pool of authors rather than the users themselves — these are "content projects".
Social networks
Social networks without a specific topic of interest, such as VK and Facebook. This type does not include social media devoted to a well-defined subject (like anime or pets) — these are "communities".
Bookmaker resources for betting on sports outcomes or any other events.

How often Yandex.Radar's Top Online Projects are updated

Online project traffic data is processed by Yandex.Radar every day, and the ranking shown is with a two-day delay. Statistics for an incomplete current month start showing from the 10th day. For instance, until the 10th of June the statistics for May will be shown in the ranking.

How "Average time", "Percentage of app users", and "Daily audience" are calculated

"Average time" reflects the average number of minutes which cross-device users have spent on a resource in the current month. "Daily audience" is the average number of cross-device users per day in the current month.

If the resource's AppMetrica data is connected, then app time will be included when calculating the average time. Statistics from AppMetrica will also improve the accuracy of calculating the daily audience and traffic indicators for the month, because these metrics will include data for mobile app users who do not visit the resource.

The percentage of app users shows what percentage they make up in the total cross-device site audience. This metric is calculate only when AppMetrica data is available.

How region, device type and demographic characteristics of audiences are determined

Only those online projects that have connected the transfer of Yandex.Metrica data are shown in regional, device type and demographic data.

The region is calculated by the IP-addresses of resource users, while the device type is by the User Agent string. Demographic characteristics are determined using Crypta technology. At the same time, all data is anonymous and does not allow you to identify a specific user.

Frequently asked questions

How can I add my resource to the ranking?
Top Online Projects automatically selects the 10,000 projects with the largest audience in Russia. Each resource is ranked automatically as soon as it makes it onto this list.
My resource was assigned to the wrong category or type. How can I fix it?
Submit the feedback form by clicking "Change category or type". This link is shown next to your project in the ranking, after the settings symbol with three vertical dots (⋮).
What are cross-device users?
In classic web analytics systems, the term "visitor" refers to a unique browser that was used to open the site. If the same user visits the site from different browsers (either on the same device or on different devices), the web analytics system registers multiple unique visitors.

However, when calculating the number of cross-device visitors, the system "recognizes" the user on all devices and in all browsers. If the same user opens the site on multiple devices, only one user is counted in the "Users (cross-device)" column.

As a result, the number of cross-device users is a more realistic measure of a site's audience. Crypta technology is used for calculating cross-device traffic to ranked projects.
It seems like the number of cross-device users for my resource is too low
The number of cross-device users is always less than the number of users in a classic web analytics system such as Yandex.Metrica, Google Analytics, and others. Cross-device traffic is a more accurate reflection of the resource's audience.

Yandex.Metrica, Google Analytics and most other systems count users by their browser identifiers. This can artificially increase the resource's audience: if the same user opens the site in multiple browsers (it doesn't matter if they are on the same device or different devices), this user is registered as several different users, even though it was actually all the same person visiting the site.

In contrast, when calculating the number of cross-device users, the system "recognizes" the user on all devices and in all browsers. If the same user opens a site on multiple devices, only one user is counted in the "Users (cross-device)" column. Crypta technology is used for calculating cross-device traffic to ranked projects.

As a result, the cross-device audience is always smaller than the number of users in web analytics systems, but the number of cross-device users is a much more accurate reflection of the resource's true audience size.
If I enable transmitting Yandex.Metrica data, what statistics for my resource will be publicly available?
The number of users in Russia will be shown for your resource. The project will also be shown in rankings by region, device type, gender, age, and income of the audience. These rankings are available after selecting a filter, which restricts the report to only projects that send accurate traffic data. For instance, you can view the number of male users in the Moscow region for a particular resource.

Other stats that will be shown for the resource include the average number of minutes that cross-device users spent on the resource during the selected time period, and the average number of cross-device users per day.
Can I disable transmitting Yandex.Metrica or AppMetrica data?
Yes, you can do this whenever you want. Statistics will stop showing up in Top Online Projects in about two days after you turn off this option in Yandex.Webmaster. Note that when you disable transmitting data, new statistics won't be sent to Top Online Projects, but data for past periods won't be recalculated.
I enabled transmitting Yandex.Metrica data, but my resource still shows the "Approximation" label
Yandex.Metrica data starts being used for the rating within about two days after this option is turned on in Yandex.Webmaster.
Do I have to enable AppMetrica data if I already enabled transmitting Yandex.Metrica data?
Including AppMetrica data is necessary only if you want your resource stats to show the app's audience coverage and you want traffic indicators to be more precise.
I enabled Yandex.Metrica data, but it looks like the wrong data is being sent to Top Online Projects — I see different numbers in Yandex.Metrica reports. Why is this happening?
First of all, you need to find out which metrics are different.
  1. It doesn't make sense to compare the Sessions column in Yandex.Metrica with the number of users in Top Online Projects, because they measure different things. To learn more about how sessions differ from users, see the Help for Yandex.Metrica.
  2. The number of cross-device users shouldn't match the number of users in Yandex.Metrica, because these numbers are calculated in different ways.
  3. The number of "normal" users in the second column of the ranking might differ slightly from the number of users that you see in Yandex.Metrica. This is because the Yandex.Metrica data is standardized in order to compare projects fairly.
These are the main reasons why the number of users in Yandex.Metrica might not match the value in the Users column in Top Online Projects:
  • Yandex.Metrica counts users from any region, and Top Online Projects only considers the Russian audience.
  • Regardless of the settings for a particular Yandex.Metrica tag, robots are filtered out of the ranking data by strict rules and behavior, and the session timeout is set to 30 minutes.
  • If the same tag is embedded on different sites, a particular project is ranked using only the data for its domain.
  • If you added AppMetrica data to Top Online Projects, traffic indicators in the rating will also include data for mobile app users who don't visit the site.

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.
