In addition to standard banners, Criteo supports a number of different ad sizes and formats across mobile and desktop:
A Sticky Footer is a Leaderboard format at the bottom of the page, that scrolls down when the user scrolls down. It’s not intrusive and the user can close the banner at any time.
This is a Skyscraper ad usually found at the side of a page. Similar to the Sticky Footer, it’s always visible as the user scrolls down.
