Fight fraud and improve eCPMs: How to implement app-ads.txt for your app

Jan 13, 2023·5 min read

Summary

App-ads.txt, an extension of the IAB Tech Lab's ads.txt standard for mobile apps, empowers developers to control authorized sellers of their app inventory, reducing ad fraud like spoofing and illegal arbitrage. Key data shows 68.7% of top 1,000 Google Play apps and 42.4% of top Apple App Store apps have adopted it, indicating a growing industry standard. Benefits include mitigating fraud, reducing blacklist risk, and improving revenue.

To implement, developers must: 1) add a developer website URL to app store listings; 2) create an app-ads.txt file on the root domain listing all authorized ad sources, formatted per IAB specs. AppLovin recommends adding their entry from the MAX dashboard, and validating the file with tools like Ads.txt Guru. Best practices include using hosting services if lacking a website, ensuring the developer domain is in MAX, and keeping the file updated.

This transparency helps buyers verify inventory authenticity, fostering a safer ecosystem.
