Founded in 2006, Admob is notably one of the best mobile ad platforms on the web for developers to fasten their web monetization. Now acquired by Google for $750 Million, the network has been rewired to incorporate the fundamental functionalities Google ad network. With over 1 million Apps running Admob, it has been successfully achieving a 200% increase rate in the CPM’s since 2013. Publishers get good revenue depending on the traffic. The Interstitial ads, in particular, fetch a higher RPM rate of $2 to $4 for Android and for iOS, it lies between $3 to $5. However, Admob suggests publishers to carefully implement interstitial ads for providing a positive user experience altogether and avoid accidental clicks. In this post, we will discuss how you can create Interstitial Ads in Admob.


Coming to ad networks, Interstitial ads are basically full-screen displays placed between content, at natural transition points like levels of a game or while switching web pages. The whole idea is to provide rich content for mobile as well as desktop users. Google states, “Interstitial ads are best suited for apps with linear user experiences. There should be very clear starting and stopping points in an app. If you have an app that may not meet these criteria (ex: utility apps like flashlight apps), consider using another AdMob ad format such as a banner ad.”

The interstitial units integrate various types of ads such as image, Rich Media, Textual, and Video. The timing of interstitial ad close option is dependent on whether the ads opt-in videos. In case the ads are embedded into a video, some ads may have up to a 5-second delay before providing a close option. According to Google policy, interstitials ad units that don’t opt for a video will offer an immediate close option. With the release of the Google Mobile Ads SDK version 7.2.1 or higher and Android version 11.4 or higher, this will be rather enforced more aggressively by Google Mobile Ads SDK.

If you uncheck on all the boxed, it can result in an error. It is required to choose at least one ad type for each unit. Google suggests, to check all the boxes for allowing a fair chance to maximize revenue for this ad unit.
  • Frequency capping: Choosing the frequency clapping is equally important. It controls the number of times an ad unit is shown to the same user. You can always choose to not select a limit, or you can also limit ads for each user by the number shown per minute, hour, or day.
