Mobile & In-App Advertising: Every Ad Format Explained (2026)

Mobile ad formats are shaped by the specific constraints and opportunities of a phone screen and an app session — smaller real estate, shorter attention spans, but also uniquely rich behavioral and location signals no desktop format can access.

Mobile Interstitial Ads

A full-screen ad shown at natural app transition points — between game levels, or between app screens — timed carefully to avoid interrupting an active task.Transition-timed

Rewarded Video Ads

An OPT-IN video ad that grants the player a real in-app reward — extra currency, an extra life, unlocked content — for watching to completion. Consistently the highest-completion-rate video format in mobile because the user actively chose to watch.Highest completion

Mobile Banner Ads

A small, fixed-position display unit anchored to the top or bottom of an app screen — low-impact, low-CPM, and still one of the simplest ways to monetize free app inventory.Low-impact

Playable Ads

A tiny, fully interactive mini-demo of a game or app, playable directly inside the ad unit itself BEFORE installing — lets a user try before they download, which meaningfully raises post-install retention.Try-before-install

Offerwall Ads

A list of app-install or in-app-action offers a user can complete in exchange for in-app currency or rewards — common in mobile gaming's free-to-play monetization stack.Gaming-specific

App Install / UAC Ads

Ads run across multiple ad networks, specifically optimized to drive mobile app downloads and, ideally, meaningful post-install events rather than installs alone.Install-optimized
