The Yandex.Metrica counter collects information on your site users' devices and software. The reports that provide this data are listed below. Reports support segmentation and goal selection.
Report on browsers and their versions.
Report on sessions of users who have the most common ad blockers installed: Adblock, Adblock Plus, Adguard, uBlock and others. Some technologies may block the Yandex.Metrica counter itself. This means that the statistics may be lower than the actual numbers.
Information about ad blockers might be useful when analyzing sources of site traffic. The report helps you understand what percentage of sessions from various sources was blocked.
To make a report like this, go to Reports → Standard reports → Sources → Sources (summary) and add the metric Metrics → Technology → Ad blockers.
Sometimes it is useful to have data about the operating system and browser that an ad blocker is installed on. To make a report like this, go to Reports → Standard reports → Technology → Operating systems. Then add the dimension Dimensions → Technology → Browser and the metric Metrics → Technology → Ad blockers.
