Account setup and basics
Where ads appear in your site or app
AdMob provides developers with complete control over where they place AdMob ads within their site or application. For optimal performance, we recommend placing ads in natural locations such as the top or bottom of an application or site.
Developers should try to place ads in a way that fits naturally within their site or application and does not interfere with normal user interaction. Your integration is also required to follow the guidelines outlined here.
