About image ads on the Display Network
Before you begin
Interstitial image ads
These are full-screen ads that tend to have higher clickthrough rates than banner ads, but may have a higher CPC. These appear as someone transitions between screens or pages in an app.
- Sizes for mobile phones: 300 x 250, 320 x 480, and 480 x 320.
- Sizes for tablets: 1024 x 768 and 768 x 1024.
Banner image ads
Banner ads appear as a small strip or “banner” across the top of an app page or screen. They’re the most commonly used ad format for mobile. You can upload double-sized images (for example, a 640 x 100 image for a 320 x 50 ad slot) for high-resolution display devices. We’ll auto-adjust the image based on the device’s pixel density.
- Sizes for mobile phones and tablets: 320 x 50, 468 x 60, 728 x 90, and 300 x 250.
By default your ads will show both as banners and interstitials. If you want to only run interstitials, go to the Display Network tab in AdWords and click + Exclusion under “Campaign exclusions.” Select “GMob mobile app non-interstitial” to exclude banner ads from your mobile app campaign.
