Interstitial ads have grown to become one of the most popular ad formats for publishers and app developers working across both android and IOs.
Statistics show that interstitials are the second most popular ad format behind rewarded ads today, with 57% of game publishers using them to monetize their mobile apps and maximize their ad revenue.
This article recaps the basics of interstitials, best practices around placement, and the best interstitial ad networks for publishers in 2021.
Mobile Interstitial Ads
While interstitials are available for both mobile and desktop ad campaigns, they are most commonly seen in mobile apps and are particularly popular with mobile game developers.
These rich media, interactive ads, are full-screen ads that cover the entire screen of a host app or device. After watching a certain percentage of the ad, mobile users then have the option to perform one of the following options:
- Close the ad and return to the mobile app
- Continue to watch through the entire ad
- Tap the ad and visit the ad’s destination page
Interstitials can be interactive, rich media ads featuring video content or static ads featuring simple text and images and are adaptable for both ios and android devices. This makes them one of the most innovative ad formats out there.
Due to their high ad viewability, immunity to ad blockers, and creative dynamism, when implemented correctly, interstitials are an excellent choice for most mobile web platforms.
Interstitial Ads: Best Practice for Publishers
While the stats around Interstitial ad revenue are undeniable, with research showing that click-through rates are 18 times higher than with banner ads, incorrect implementation can interfere with user experience, lead to page lag and negatively affect ad revenue opportunities.
Before examining which interstitial ad network may best suit their needs, publishers should first understand interstitial ad best practices in order to leverage the monetization platforms for maximum ROI.
Ultimately, interstitial ad placement best practice comes down to timing. Google states that interstitial ads should be placed at a point in the game to ‘complement the natural flow of user engagement’.
Google advises publishers that they should ask themselves the following questions when it comes to interstitial implementation.
- How will the user be engaging with my app at the time?
- Will the user be surprised by the interstitial ad?
- Is this the right time for an interstitial?
