What is app-ads.txt? Ads.txt for mobile apps
On March 10, 2019, IAB officially announced the release of Ads.txt for mobile apps (app-ads.txt) to fight against unauthorized reselling of inventory. App-ads.txt is an extension of the IAB ads.txt initiative launched for websites in 2017. Authorized Digital Sellers for Mobile Apps (app-ads.txt) has been released to allow mobile app publishers to publicly declare the specific advertising systems which are authorized to sell their digital advertising inventory.
How does app-ads.txt work?
App-ads.txt is a plain text file hosted on the domain of the app developer’s website to identify their authorized digital sellers. This method allows advertisers to trust that they are buying authentic app inventory.
Buyers that bid on app inventory can use the app-ads.txt which has been declared by the app developer on their website in order to verify that their impressions come from authorized sellers.
Is there any free app-ads.txt hosting?
Yes, App-ads-txt.com has been created specifically to enable mobile app developers to host their app-ads.txt for free without the need of any domain, website or any other additional developments.
