Fill rate advertising
What is fill rate advertising?
Ad fill rate is an app metric which measures ad network performance. Fill rate is calculated by dividing the number of ad impressions an app shows by the number of times an app has requested an ad from an ad network.
What is the fill rate formula in advertising?
Fill rate = impressions / ad requests
In addition to looking at which ad network can deliver the highest eCPM, app developers also look at which network can deliver the highest fill rates - since these are the networks which can fill a high percentage of app requests. A higher ad network fill rate means app developers are able to generate more ad revenue.
