The advantage of these ads is straight-forward and can supplement in-app payments. Advertisers like the ads because they only pay if the viewer takes the desired action—but the completion and install rates are very high. This lets publishers charge a high eCPM, but it centers around the fact that users opt in to seeing them.
Interstitials
Although rewarded videos dominate the mobile in-game ad experience, many developers also use interstitial video placements. The two video types have different purposes: Rewarded video often complements in-app purchases, giving users a free way to gain some small value within a game (that otherwise might be purchased with real currency). Interstitials fill otherwise unmonetized pauses within games.
Interstitials and rewarded video often have “end cards,” a final ad screen with a call to action. Depending on the advertiser, end cards might invite users to tap for directions to a store, install an app or view a rich media experience, such as a playable ad.
Playables
Another ad unit that has benefited from the move to interactive and engaging formats is the playable ad, which is a miniversion of the advertised game or a branded minigame. The ad works best when it replicates the most representative level within the advertised game. This requires analysis of the gameplay to see where players are most engaged and then building the same experience into the ad. The net effect of a well-designed playable ad isn’t just higher clickthrough rates and CPMs or cost per action (CPAs), but also better post-install engagement.
Banners
The growth of hypercasual games—games that are very easy to learn and have short game loops—has also been a boon for banner ads. They remain an important unit in a wide range of games sometimes as a complement for increasingly sophisticated and interactive rewarded video and rich media ads but also as the main monetization tool in games that don’t have an internal purchase economy, lending themselves naturally to rewarded video.
More recently, new technologies offered by companies like Bidstack and Admix can insert banner ads into the gameplay itself, effectively turning them into native ads. For example, the banner could be placed on a flag on the side of a racecourse or the arena walls in a sports game. These are native ads, but the creative is a standard banner ad bought programmatically that has been transformed to fit seamlessly into the game’s world.
