App-ads.txt is a list of authorized sellers that publishers provide DSP with their APP ad sources.Publishers use the file to designate authorized digital sellers of their ad inventory, and DSPs use it to validate that they are buying inventory through an authorized source.Publishers host this file on the root domain of their website that is linked from the Google Play Store or Apple App Store. When an ad request with an app is sent out, an advertiser can check the app-ads.txt file, and verify that the publisher ID included in the ad request matches the corresponding ID in the app-ads.txt file to avoid ad fraud.
If you don't implement app-ads.txt, it may hurt your eCPMs because there will be less advertisers willing to pay you for ads.Implementation is optional, but we strongly recommend it for the purpose of transparency.
