Yes, a developer can have different app-ads.txt files for each of their apps. The app-ads.txt standard is designed to be implemented on a per-app basis, allowing developers to specify the authorized sellers for each individual mobile app. Each app can linked to a specific domain, and each domain can contain only one app-ads.txt file.
Here’s how it works:
- Individual App Authorization:
- Each mobile app has its own
app-ads.txtfile, typically hosted on the developer’s server. This file lists the authorized digital sellers or entities that are permitted to sell ad inventory for that specific app.
- Each mobile app has its own
- Unique File per App:
- Developers create a separate
app-ads.txtfile for each app they own. This file includes the specific information about authorized sellers relevant to that particular app.
- Developers create a separate
- Placement on Developer’s Server:
- The
app-ads.txtfile for each app should be placed at the root level of the developer’s website or server. For example, the file for “Example App” might be hosted athttps://example.com/app-ads.txt.
- The
- Ad Buyer Verification:
- Advertisers, ad networks, and demand-side platforms (DSPs) can then check the
app-ads.txtfile for a specific app to verify the authenticity of the sellers when considering purchasing ad inventory within that app.
- Advertisers, ad networks, and demand-side platforms (DSPs) can then check the
This approach allows developers to tailor the list of authorized sellers for each app based on their partnerships and business arrangements. It also provides a granular level of control over the advertising inventory for each app within the developer’s portfolio.
If a developer has multiple apps, it’s essential for them to manage and update each app-ads.txt file independently to accurately reflect the authorized sellers for each app. Advertisers and the advertising ecosystem, in general, can then use these files to ensure they are dealing with legitimate and authorized sellers for a specific mobile app.
