Dynamic Impressions – SEO WIKI
Dynamic impressions are a search contextual advertising area in Yandex under organic delivery on the second and subsequent search pages:
Sometimes the block of guarantee impressions is placed not after the organic issuance, but to the right of it, and in this case the zone of dynamic impressions may include up to 5 announcements.
Line items for dynamic impressions are calculated using the GSP auction. Direct impressions in Yandex.Direct attract the least traffic, but their campaigns are cheaper than the rest.
