What is Anchor ads
Anchor ads stick to the edge of the user’s screen and are easily dismissible. These ads mainly serve on mobile but can appear on desktop too. They appear at the top of the user’s screen unless we determine that this would negatively affect the user experience, in which case we show them at the bottom. When shown at the top, anchor ads only appear after the user has scrolled down far enough, so that they never cover your site’s branding or navigation. If you don’t want to show anchor ads you can turn this option off
