What does this tool do?

The Ads.txt Validation Test is a tool that helps publishers and advertising platforms ensure compliance with the Ads.txt file specification. The Ads.txt file is a simple text file that publishers can host on their web servers to declare which advertising systems are authorized to sell their digital inventory.

The Ads.txt Validation Test performs the following checks:

1. File Presence: It checks if the Ads.txt file is present on the publisher's web server at the standard location (example.com/ads.txt).

2. File Format: It validates if the Ads.txt file follows the correct format specified by the Interactive Advertising Bureau (IAB). This includes checking for correct syntax, line structure, and the use of valid identifiers for advertising systems (accounts, certification authorities, etc.).

2. Authorized Digital Sellers: It verifies if the advertising systems listed in the Ads.txt file are authorized to sell the publisher's inventory. This is done by cross-checking the listed entities against known lists of certified advertising platforms and resellers.
