Declare sticky ads on display

To improve viewability and ad performance, some publishers may choose to implement their ad units as "sticky ads." A sticky ad is a persistent/fixed ad unit that stays visible while the user scrolls content on the page up or down.

If you use sticky ad units for display, you must set up rules that declare their existence. Learn more about the guidelines and restrictions for implementing sticky ads.

The necessity of setting up rules does not apply to anchor ads on web pages.

Publisher declarations apply to Open Auctions, Private Auctions, First Look, and Open Bidding.
