An adhesion ad is a display ad that sticks to the bottom of the browser window as a reader scrolls through your site. 

Adhesion units stay with the reader as they scroll. This makes them highly viewable. The more viewable an ad unit is, the more lucrative it becomes. 

High Viewability = High CPMs

Adhesion ads also refresh every 30 seconds, so for readers that spend time on your site they are likely to be served multiple impressions in the adhesion space.

If you have Optimize for Pagespeed settings enabled (recommended) adhesion ads are deferred from the initial screenview for 5 seconds in the Chrome browser. This aids with pagespeed measurements as well as Core Web Vitals.

Adhesion Ads are enabled on mobile, tablet, and desktop with every new launch. You can find the settings in your dashboard > ⚙️ Settings > Ad Settings.

You can also adjust the background color of Adhesion Ads by changing the Adhesion Wrapper Theme. We offer light and dark options so you can select whichever fits best with your site design.

Make sure that if you run floating sharing buttons, back-to-top buttons, or a feature set like Slickstream (USE GROW INSTEAD AND MAKE MORE MONEY!) on mobile, tablet, or desktop, that these do not overlap Adhesion Ads. Having these cover the ad can cause accidental clicks, which result in policy violations, and cause trouble for you with the ad exchanges. 

You can report adhesion ads that are appearing as broken creatives by using the Mediavine Ad Reporter. If you do not see the Mediavine logo with the option to report, you can grab a screenshot of the ad, and right click on the ad to grab the URL where the ad leads to. 

Email those details to publishers@mediavine.com, and we'll report it to the necessary ad partners.
