To prevent ad placements from rotating and causing the page to jump around, you can ensure your ad slot heights remain consistent across all served ads. This feature forces the ad slots to stay the same size, which provides a smoother user experience.

Follow the steps below to enable this setting:

1. Navigate to the Websites Tab
   • On the right-hand side of your dashboard, find and click on the Websites tab.
2. Select the Site You’re Working On
   • Locate the website you want to adjust and click Settings next to that site.
3. Go to the 'Ad Server' Tab
   • In the settings menu, click on the Ad Server tab at the top of the page.
4. Enable the 'Keep Ad Slot Height Fixed' Option
   • Scroll to the bottom of the Ad Server tab, where you'll find the option for Keep Ad Slot Height Fixed.
   • Toggle the switch to enable this feature.

Once enabled, all ads served within that slot will maintain the same height. The first ad that loads will determine the height for subsequent ads, which must either be the same size or smaller. For example, if a 300px ad is served first, the following ads will need to be 300px or smaller to fit within the slot without causing any layout shifts.

This setting helps ensure that your page layout remains consistent, even when different ads are served.
