How to work with segments

Yandex.Audience segments can be used to create ad campaigns in Yandex.Direct and Yandex.Display.

These segments are updated regularly. New cookies are automatically added to them and old ones are deleted. This way segments only include cookies that were active in the last 30 days. These identifiers become active when someone uses their app or browser. Of course users can change browsers, re-install apps and acquire new devices, so segment coverage can change over time.
Note. Segment coverage is recalculated only when a segment or one based on a segment of similar users is used in ad campaigns in Yandex.Direct or Yandex.Display.

You can also use the API to manage your Yandex.Audience segments and access settings.
