Yandex.Direct has started marking ad groups as “rarely served” if their keywords have extremely low search volumes. These “rarely served” ad groups are automatically removed from auctions, meaning that they are effectively paused, thus saving the advertiser money. The ad groups get reactivated if the keywords' search volumes rise above a certain threshold. If an ad group gets marked as “rarely served”, then the advertiser will be given tips on how they can alter their ad groups so that they get higher search volumes, whether that be by changing their keywords, targeting settings or both. Yandex is checking search volumes regularly, meaning that advertisers should not miss out on seasonal or irregular spikes in search volume.Â
