Interstitials take over the full screen at natural break points — between levels, on app open, between articles — so the ad is the only thing on screen. The ad gets full attention, but our frequency caps protect UX. Average 2.0–6.5% CTR — the highest of any display format.
Interstitial ads are full-screen advertisements displayed between content transitions — typically between two pages of a site, between levels of a game, or after a video completes. The format takes over the entire viewport and demands full user attention until either dismissed or the configured display time elapses. Because they're so high-impact, they're also frequency-capped by default (Mondiad's default is one interstitial per 24 hours per user) to protect the user experience and prevent fatigue.
Of all standardized display formats, interstitial has the highest click-through rate (2.0-6.5% average on the Mondiad network) and the highest brand recall. The tradeoff is impression cost: you pay a premium CPM because the format consumes premium screen real estate and is rate-limited per user. Interstitial works best in apps, gaming sites, content sites with paginated articles, and streaming platforms where natural content-break moments exist. Used carefully — and frequency-capped properly — interstitial delivers more value per impression than any other display format.
User finishes an article, completes a video, transitions between pages or app screens.
Full-screen ad renders during the natural pause. Frequency-capped to once per 24h by default.
User can dismiss at any time (close button is mandatory after the first second).
User either dismisses (no charge for non-interaction) or clicks through. Standard S2S tracking.

The honest take on when this format wins — and when another format wins.
Interstitial has 10-20× the CTR but 4-8× the CPM. Per-conversion economics often favor interstitial for high-CPA verticals.
Interstitial demands attention; native earns it. Different psychology — interstitial works for high-impact moments, native for sustained engagement.
Both are high-attention formats. Interstitial appears in-flow; popunder appears post-flow (behind the browser window).
Interstitial is full-screen and blocks content; dynamic is anchored and non-blocking. Different use cases.
"Tested interstitial vs banner on the same mobile-app-install offer in BR. Interstitial CPC was 4× the banner CPC, but install rate was 11× higher. CPI ended up 38% lower on interstitial."
