App-ads.txt Implementation

info

Important: App-ads.txt is required for all Teads SDK implementations to ensure inventory protection and maximize revenue potential.

What is app-ads.txt?​

App-ads.txt is a standard released by the IAB Tech Lab that extends the original ads.txt standard for mobile applications.

This standard helps eliminate the ability to profit from counterfeit inventory in the open digital advertising ecosystem across mobile apps, OTT, and other app inventory. It provides a mechanism for content owners to declare who is authorized to sell their digital advertising inventory.

Why is app-ads.txt important?​

  • Inventory Protection: Prevents app inventory from being spoofed by bad actors
  • Revenue Optimization: Ensures advertisers can target the proper audience
  • Industry Compliance: Required by major DSPs and ad platforms
  • Fraud Prevention: Builds a safe and transparent advertising ecosystem
warning

Revenue Impact: Not listing Teads in your app-ads.txt will directly impact ad serving and revenue potential from our demand partners.

Implementation Steps​
