Google has announced two new ad formats for App Install ads, the first one is the coolest, the ability to test an app without downloading it using the app streaming feature we discussed earlier.

In short, this is called Trial Run Ads and it lets the user click on the ad, test out the app for 60 seconds with a banner to download the app via Google Play. There is even a 60 second count down on the ad, which is cool. Here is an animated GIF of it in action:

The next is a new interstitial format that brings interactivity through HTML5. Google said this is a “beta for Interactive Interstitial ads, which are HTML5 ads that offer a completely customized user experience tailored to each advertiser’s app.”
