Heavy Ad Intervention

This detects whether the ad will trigger Chrome's heavy ad intervention.

Why do we test it?

Ads that consume too much CPU, memory, or bandwidth may be blocked by Chrome to preserve the user experience. Avoiding heavy ads ensures compliance and prevents ads from being blocked.
