How To Add APP-ADS.TXT to Increase Fill Rate

What is app-ads.txt?
App-ads.txt standard was introduced to prevent unauthorized or domain-spoofed app inventory and to help fight ad fraud. Apps-ads.txt is a text file that app developers are requested to upload to their publisher website. It defines all ad sources authorized to sell that publisher’s inventory.

How does this work?
‍Many demand-side partners are now enforcing this standard, meaning that publishers without it will suffer from much lower fill rate. DSPs and demand sources wanting to bid on an app’s inventory will look for the app-ads.txt file on the developer’s website to verify which ad sources are authorized to sell that app’s inventory.

How to create your app-ads.txt?
