Also they suggest to make Authorized Sellers for Apps (app-ads.txt)

standard, originally designed for protecting web ad inventory. It extends compatibility to support ads shown in mobile apps.

Use of app-ads.txt is not mandatory, but is highly recommended, especially if you are concerned that others may be spoofing your app.

You need to create website (domain) and create txt file name it "app-ads.txt" place it in root...

put inside it google.com, pub-xxxxxxxxxxxxx, DIRECT, f088c47fec942fa0

pub-xxxxxxxxxxxxx change this with yours..

in app listing in store add link of your website
