Benefits of app-ads.txt
app-ads.txt is a small text file, but it changes who can make money on your app’s ad space — and how much advertisers are willing to pay for it.
For publishers
- Control over who sells your inventory — only the accounts you list can be verified; everyone else is ignored by careful buyers.
- Higher eCPMs — verified inventory gets more bids; unverified traffic is often skipped or bought cheaply.
- Protection from impostors — a clone or a fake seller can’t pass as your app, because it can’t edit your developer website.
- Less revenue leaking to unauthorized resellers who sell your impressions below their value.
For advertisers and buyers
- Verifiable supply — each seller can be checked against a file only the publisher controls.
- Less money lost to fake impressions and clicks, which improves return on ad spend (ROAS).
- Brand safety — ads run in the real app, not in a counterfeit copy.
The three problems it targets
- Unauthorized reselling — someone sells your ad space without your consent, usually cheaper.
- Counterfeit inventory — a vendor claims access to inventory it doesn’t have.
- Domain / app spoofing — fake traffic disguised as a legitimate app. See domain spoofing.
The condition: a correct, current file
The benefits only hold when every line is valid and the list is complete — including the partner (RESELLER) lines your networks expect. A file with errors or missing lines quietly loses demand. Check yours free to see errors and missing lines in seconds.
FAQ
Does app-ads.txt increase revenue?
Indirectly: buyers pay more for inventory they can verify, and unauthorized sellers stop taking a share. Apps without a valid file are often bid lower or skipped.
