In this report, you can see data on all robot activity on the site, with a breakdown by filter settings. For the list of Yandex robots, see the Help for Yandex.Webmaster.

The table shows the number of times the Yandex.Metrica counter sent data, and robot activity on the site (other than WebVisor sending data). The information is displayed in rows, broken down by filtration rules.

Statistics filters are shown in a separate line and are not elaborated on. For strict rules, the rule that was triggered is shown. For example, the name of the robot that noted itself in the User Agent directive is shown.

If the line specifies the rule “Filtered by lack of JS and Referer”, this means that the user did not have JavaScript support, and when the image was loaded, the HTTP Referer header (the address of the viewed page) was not passed.


The counter code consists of two parts — the JavaScript code and an invisible image specified in the noscript element. If JavaScript is not supported or is disabled during the user's session, the image is loaded to pass information about the viewed page in the HTTP Referer header. If the HTTP header is not passed, Yandex.Metrica interprets it as a robot session.

To not filter these types of pageviews, select the Include all robot sessions option in the Filters section on the counter editing page.


You should enable robot filtering by strict filters and behavior if you have discovered hints of unnatural traffic in the Robots report and you have reason to believe that this situation will reoccur.

For some websites, a certain persistent volume of robot traffic is not critical. In this case, the filter selection remains up to the counter owner's discretion.
