Ad networks + publisher IDs
Generated file

Why this matters
This is the quick win of the set: five minutes of pasting IDs protects your ad inventory from unauthorized resellers. The only subtle part is hosting it on the domain your store listing actually declares — which is exactly what the listing-domain check verifies.
Frequently asked questions
What is app-ads.txt?
The IAB Tech Lab authorized-sellers file listing which ad networks may sell your app's inventory. Ad networks crawl it to block unauthorized reselling — missing or wrong entries cost revenue, not just compliance points.
Where do I find my publisher ID?
In each ad network's dashboard (e.g. AdMob pub-XXXXXXXXXXXXXXXX). Paste one per selected network — the tool formats the domain, ID, and DIRECT/RESELLER relationship per the spec.
Where do I host the file?
At the root of your developer website: https://your-domain/app-ads.txt. The tool flags it when that domain doesn't match your Play listing's declared website, since crawlers start from the listing.
What do I get to download?
Correctly formatted app-ads.txt content with the required hosting path stated. Free.
