Overview of app-ads.txt
What is app-ads.txt?
Authorized Sellers for Apps, or app-ads.txt, is an IAB initiative that helps protect your app ad inventory from ad fraud. You create app-ads.txt files to identify who is authorized to sell your inventory. Identifying authorized sellers can help you receive advertiser spend that might have otherwise gone toward counterfeit inventory of spoofed apps.
The app-ads.txt files are publicly available and crawlable by exchanges, supply-side platforms (SSP), and other buyers and third-party vendors.
Authorized Sellers for Apps (app-ads.txt) is an extension to the Authorized Digital Sellers (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.
