On March 13, 2019, IAB Tech Lab’s OpenRTB working group released a standard that helps to prevent unauthorized inventory trade: app-ads.txt. By now it has become one of the most successful and widely embraced mechanisms that solve the problem with domain-spoofed mobile app inventory. App-ads.txt is an extension of ads.txt released by IAB in 2017 for web inventory. The new app-ads.txt standard enables app developers to certify their inventory just like website owners do.
Since starting from August 27, 2019, Google will block ads that come from unauthorized sellers, SmartyAds recommends app developers to prepare app-ads.txt file as soon as possible. This will help you to stay valid on buyers’ target media lists’ and will protect your monetization incomes in the future.
What is App-ads.txt?
App-ads.txt file indicates the names and IDs of all sellers who can legitimately sell mobile and CTV advertising inventory. After the implementation of app-ads.txt, advertisers are able to bid on mobile placements only from those sellers that are listed in the file.
