These ads can be displayed in Yandex Search, Direct Product Gallery, Yandex Advertising Network, and Yandex Maps. Yandex explained:
Instead of creating many separate ads with different messages, it is enough to add as many options for elements as possible into one ad. Banners will be automatically generated from them, and Yandex Advertising's neural technologies will determine the most effective one for each impression.
By uploading multiple images and videos with different aspect ratios, the most suitable ones will be displayed in the required proportions on each platform.
Currently, the tool is only available to some users. The ability to configure "Combinatorial Ads" will gradually appear in all advertising accounts.
