✅ What is app-ads.txt?

app-ads.txt is a simple text file that lists all the advertising networks and resellers that are officially allowed to sell ads for your app.

It is the apps version of the ads.txt standard used by websites.

🔎 Why it matters

• Prevents fraud: Blocks unauthorized sellers from pretending to sell your app traffic.

• Improves revenue: Buyers trust your inventory and bid higher, increasing eCPM.

• Required by networks: AdMob and many others now expect it for proper verification.
