Overview

Authorized Digital Sellers, or ads.txt is an IAB Tech Lab initiative that helps ensure that your digital ad inventory is only sold through sellers (such as AdSense) who you've identified as authorized. Creating your own ads.txt file gives you more control over who's allowed to sell ads on your site and helps prevent counterfeit inventory from being presented to advertisers.

The ads.txt files are publicly available and crawlable by exchanges, supply-side platforms (SSP), and other buyers and third-party vendors.

The mission of the ads.txt is simple: Increase transparency in the programmatic advertising ecosystem. ads.txt stands for Authorized Digital Sellers and is a simple, flexible and secure method that publishers and distributors can use to publicly declare the companies they authorize to sell their digital inventory.
