What is Ads.txt?
Ads.txt is a new standard for websites to communicate which ad networks are authorized to sell inventory on a site. The ads.txt initiative is led by the IAB and is designed to fight ad fraud.
Transparency in the ad supply chain allows advertisers to know if the ads they buy are legitimate. Ads.txt does not stop all ad fraud, but as publisher adoption increases it becomes harder for fraudsters.
How ads.txt works is simple. Participating publishers place a text file called "/ads.txt" on the root of their domain. Then publishers, exchanges, and third-parties can quickly check to verify authorized sellers.Learn more
