Technologies used in the Yandex Advertising Network

Each day, millions of internet users view ads on Advertising Network sites.

To make ads more interesting to site users and more effective for advertisers and ad platforms, Yandex actively develops its own technologies:

  • Data collection on users and pages. A substantial portion of the ads on Yandex Advertising Network sites are contextual ads that are displayed to users based on their particular interests and web page content. The individual interests of users are determined by their behavior when using Yandex services or their behavior on partner sites of the Advertising Network. The Crypta technology is responsible for classifying socio-demographic groups. Various user interests are accounted for when displaying behavioral advertisements. A page's theme is determined by the Yandex Advertising Network robot that regularly crawls the pages of sites on the Advertising Network.
  • Effective targeting system. We employ 15 types of targeting when selecting ads to serve. They include 8 schemes based on behavioral targeting (including automatic retargeting for all clients that use Yandex Metrica), 6 based on contextual targeting, and 1 based on audience targeting, which adapts to the interests of users across several ad platforms and regions and is capable of predicting trend changes (for example, during holidays or other "peak" seasons). Owing to all the above targeting, suitable ads are selected for each user on each specific page.
  • Predicting click probability. Ads are automatically selected for impressions on the Advertising Network according to the maximum expected revenue. The machine-learning system MatrixNet is used to forecast click probability. It takes into account more than 120 ranking factors, which means that we select the ads that are most interesting to users and most profitable to our partners.
  • Testing ad unit visibility. Advertising Network statistics only count impressions that actually allowed a user to have contact with the ad. In other words, for an impression to be counted, the ad unit must be at least partially in the user's field of view, and the contact time must be sufficient for the user to actually see the ad. Data on ad unit visibility is provided in the Yandex Advertising Network interface.
  • Filtering invalid clicks. We employ multi-factor technology that includes automatic and manual filtering methods to combat fraudulent or accidental clicks. This means that our ad network enjoys the well-deserved trust of advertisers.
