ads.txt for Publishers
Implementing ads.txt is crucial for publishers who want to enhance transparency and safeguard their ad inventory. This guide will provide you with clear instructions on setting up the ads.txt file and designating authorized sellers effectively.
What is ads.txt?
The ads.txt (Authorized Digital Sellers) file is a simple text document that allows web publishers to declare who is authorized to sell their digital advertising inventory. Launched by the IAB in 2018, this initiative helps prevent unauthorized sellers from profiting off your inventory.
For mobile app publishers, the equivalent file is app-ads.txt, which serves the same purpose within mobile environments.
