Implement & manage Ads.txt on your domains

If you want to add additional lines to the ones provided in this guide or need additional information, use the following resource: IAB Ads.txt page

Publishers can create an ads.txt file in Notepad or any other basic text-editing program according to the specifications set out by the IAB. The Ads.txt file must contain the following fields:

Mandatory fields:

Domain name of the advertising system, SSP, or an ad exchange (ex. ‘google.com');

Publisher account ID (a unique string of numbers/letters);

Type of relationship (‘direct’ or ‘reseller’);

Optional field:

Certification authority ID (currently TAG ID);

Comments can be added in the file after the “#” symbol. The comments will not be taken into account by the crawler

This is how the string would look in an “/ads.txt” file:
