Set up impression criteria

Media-contextual banners are currently undergoing beta testing.

The keyword determines which search queries will trigger banners from the group to display on Yandex search. For example, if you set the keyword tours to outerspace for your banner group, your banners will be triggered by the search queries tours to outerspace, discount tours to outerspace, etc., but they will not be triggered by the queries tours or outerspace.

When displaying ads, the system accounts for all forms of a word within the same part of speech, including singular and plural forms. For the keyword tours to mars, for example, your banner will display if the user searches for tour to mars or tourS to mars.
