Interstitial Ad — Definition & Explanation

A full-screen ad that covers the entire interface of the host application or website, typically displayed at natural transition points. Interstitials command premium CPMs but must be used carefully to avoid hurting user experience and search rankings.

How Interstitial Ad Works

Interstitials trigger at navigation events (page transitions, level completions in games) and display full-screen before users can access their intended content. They must include clear close buttons and respect Google's interstitial guidelines for mobile SEO.

Why Interstitial Ad Matters for Publishers

Interstitials command 3-5x higher CPMs than standard display. However, excessive or poorly placed interstitials can cause Google ranking penalties and high bounce rates that hurt long-term revenue.

Interstitials typically command $5-20+ CPMs for display and $15-50+ for video, depending on traffic quality and content category.
