Backup Ad Found

A backup ad is a static image that can be displayed if the HTML5 ad fails to load.

Why do we test it?

Including a backup ad ensures that something is displayed even if the interactive HTML5 ad encounters issues, preserving the advertiser's opportunity to show their message and improving the reliability of the campaign across various platforms.
