Host an ads.txt/app-ads.txt file
After you create an ads.txt/app-ads.txt file, have your webmaster upload the file to your root domain.
- "Root domain" is defined as one level down from the public suffix list, which is how it's defined in the IAB specifications for ads.txt and app-ads.txt.
- Example: "
google.co.uk" would be considered a root domain as "
co.uk" is on the public suffix list, but "
maps.google.co.uk" would not be considered a root domain.
Examples of ads.txt/app-ads.txt files
Publishers working with Google products should always use
google.com as the domain name, with their publisher ID. For example:
google.com, pub-0000000000000000, DIRECT, f08c47fec0942fa0
google.com, pub-0000000000000000, RESELLER, f08c47fec0942fa0
Publishers working with other non-Google products should list their SSP or exchange domain names, with their seller account IDs. For example:
greenadexchange.com, 12345, DIRECT, AEC242
blueadexchange.com, 4536, DIRECT
silverssp.com, 9675, RESELLER
