Quick Tool Overview

The ads.txt Generator writes authorised digital seller records in the exact comma-separated format the IAB specification requires, with the common networks preset so you need only your publisher ID.

About the ads.txt Generator

Add each ad partner with your publisher ID and the generator writes the ads.txt records in the exact comma-separated format the IAB specification requires. Common networks are preset, so AdSense, Ad Manager, Amazon and the rest need only your ID.

ads.txt exists to stop domain spoofing, where someone sells fake inventory claiming to be your site. Publishing the file at yourdomain.com/ads.txt declares which sellers are authorised, and buyers check it before bidding. The format is unforgiving: each record is exactly the exchange domain, your publisher account ID, the relationship (DIRECT if you have a contract with them, RESELLER if they resell on your behalf), and optionally the TAG certification ID — comma separated, one per line. A single malformed line is skipped silently, which is why an invalid file usually shows up as revenue that quietly does not arrive.

Key features of the ads.txt Generator

Networks preset

AdSense, Ad Manager, Amazon, Criteo, Index Exchange, Magnite, PubMatic, OpenX and more, with the right domains.

DIRECT and RESELLER

The relationship field is explained rather than guessed at, since getting it wrong stops a partner bidding.

Format validation

Malformed records are skipped silently by buyers, so they are caught here instead.

app-ads.txt too

The same records in the app variant, with a note on where that file actually has to live.

Duplicate detection

The same seller and ID listed twice is flagged rather than shipped.

Frequently asked questions

At the root of your domain, exactly at yourdomain.com/ads.txt, served as plain text. It cannot be in a subdirectory, and crawlers do not look anywhere else. For subdomains that sell their own inventory, each needs its own file.
