- Banner Ads: These are small, rectangular ads that appear at the top or bottom of the app screen. They are less intrusive but may also be less engaging. - Interstitial Ads: These are full-screen ads that appear at natural transition points in the app, such as between levels in a game. - Video Ads: These ads can be skippable or non-skippable and often appear before or after video content within the app. - Native Ads: These ads match the look and feel of the app content, offering a seamless integration that can enhance user engagement.
