The IAB Technology Laboratory has released the app-ads.txt specification in beta, the much-awaited app guidance that can increase the pool of authorized digital advertising inventory while reducing fraud
Available for public comment through February 4, 2019, app-ads.txt is an extension of the original ads.txt standard that provides a mechanism for content owners to declare who is authorized to sell their inventory
With demand-side platforms (DSPs), it allows buyers to confidently purchase through approved seller accounts. App-ads.txt applies this ads.txt functionality to ad transactions in mobile apps, as well as over-the-top (OTT) video apps.
In addition, app-ads.txt can help identify and block instances of unauthorized developer impersonation. The specification details how to get an app developer’s website URL from the app listing page within an app store, which should have minimal implementation burden for any app store
Publishing authorizations in an app-ads.txt file on the developer’s website will create a centralized online resource that the developer independently controls. As a beta specification, this can be implemented now and then app stores can also adopt a standardized way
The IAB Tech Lab encourages adoption of this beta specification for publishers and app stores, as minimal changes are expected. Not only is this specification based on one already in use,
The beta release of app-ads.txt addresses an important gap in eradicating fraudulent inventory. While it took longer than expected to define a reliable, scalable approach to specifying file locations for mobile apps, the solution will not only support ads.txt but will also support other supply chain safety initiatives, such as ads.cert.
