ads.txt
How do ads.txt work?
In order to guarantee the authenticity of the app inventory they purchase, advertisers can trust that they are purchasing authentic app inventory through the ads.txt file that identifies authorized digital sellers by hosting it on the domain of the app developer’s website. Buyers can use the ads.txt declaration on the app developer’s website as a means of verifying that impressions generated by authorized sellers are delivered to buyers who bid on app inventory.
