Displaying ads in mobile games has always been one of the essential but complex topics. However, that was before Unreal Engine started supporting ads (meaning that you can add some banners inside your games to gain revenue from them), and now it has become much easier.

Currently, Epic supports iAd for iOS devices, but if you are more interested in integrating other ads services, then you will need to contact the provider, work on writing your own wrapper for it, and then compile the editor.

To show an ad banner, you just call a node named Show Ad Banner and you'll find that it is tagged as EXPERIMENTAL if you are running the older editor version. This node has only one option with a checkbox. If the Show on Bottom of Screen option is checked, the ad will be displayed at the bottom of the screen, otherwise it will run on the top section of the screen.
