To improve performance for you, we constantly analyze data from our network. One of the most important contributors to click performance is how you choose to integrate ads. Below are our policies and some tips for you to take into consideration:

• Ads should not be placed close to or underneath buttons or any other object that users may accidentally click while interacting with your app or site.
• Ads should not be placed in a location that covers up or hides any area that users have interest in viewing.
• Ads should not be placed in areas where users randomly click or place their fingers on the screen. We recommend implementing our ads on a title or ending page.
• Ads should not be placed on a “dead end” screen. There must be a way to exit a screen without clicking the ad (such as a “back” or “menu” button). Otherwise, the user should be notified that the home button exits the app or site.
• Ads should not be pre-cached, cached or stored in any fashion. All ads should be requested dynamically and refreshed when the page is refreshed.
• The number of ads on a single page should not exceed one if the ad is fixed to the screen top or screen bottom. If the page scrolls, there should be a maximum of one ad on the top and one ad on the bottom, and both ads should not appear on the same page.
• Click-through URLs should not be proxied. All developers and publishers should pass AdMob’s click through URL to the client exactly as it is returned by AdMob.
• Register different apps or sites separately and use different developer and publisher IDs. Using one developer or publisher ID across multiple apps or sites limits our ability to optimize performance.
• For apps, use filter settings that are as permissive as possible so you can ensure the most ads possible are available to be served on your app. This helps to keep the fill rate as high as possible.
• For gaming apps, we recommend placing ads on title or ending screens, rather than mid-game to encourage a good user experience and optimal performance.
