Long gone are the days when interstitials were synonymous with static pop-ups at bootup. The former methods of implementing interstitial ads drove huge volumes to advertisers who were eager to gain new audiences and climb the app store charts. But today, the dynamics of mobile advertising are completely different. Advertisers and publishers alike now prioritize quality over quantity. In other words, success is not measured solely with impression volumes but also with eCPMs (for publishers) and ARPU (for advertisers).This trend led us to highly engaging formats such as rewarded placements, capturing the deserved attention from many in the industry. While game developers and publishers focus their time and budget here, they should not forget about the value of our old friend the interstitial. This format isn?t going anywhere just yet, and I?d like to share with you why it might be resuscitated in 2018.

Interstitial placements are in your control

Publishers have the tools to unlock new placements and segment their funnel to create the best gameplay and advertising experience. Remember: we are after quality, not quantity! And we all know that implementing advertising placements in your game can?t be an afterthought. Advertising placements need to be tied to the gameplay experience and the expected behavior of players.This is why we?ve seen a surge in the number and types of interstitial ad locations, from the traditional home screen to achievement or in-app store pages. Performance varies significantly, but you can hone in on what works for your games. Below, you can find some examples based on installs per 1000 impressions (IPM):Learn more about how to set up different ad locations in your mobile game here.
