Apple measures the quality of an ad by determining how relevant the app is to a keyword, which in turn affects the display and price of the ad. The greater the relevancy, the more display it will receive; the less relevancy, the less display it will receive, or even zero display.

When Apple determines that the relevance between an app and a keyword is low, even if you bid higher, the ad will not be shown. This shows the importance of relevance in the bidding system.
