What is ads.txt?

Ads.txt stands for Authorized Digital Sellers and is a text file that allows web publishers to publicly declare who is authorized to sell their digital inventory.

This creates greater transparency in the inventory supply chain, and gives publishers control over who sells their inventory, making it harder for fraudulent actors to profit from selling counterfeit inventory.

After the success of the ads.txt initiative, the Interactive Advertising Bureau brought it to mobile. Learn more about app-ads.txt.
