Ads.txt Instructions
The purpose of ads.txt is to prevent internet fraud by allowing buyers to verify that sellers are authorized by the publisher to sell that specific inventory. Ads.txt implementation is required to link your domain to buyers / demand.
Our ads.txt file MUST be placed and remain on your domain (example: https://domain.com/ads.txt), for BOTH approvals by exchange partners AND ongoing buying and displaying (filling) of ads on your site. If our ads.txt file is not implemented, or is removed, ad fill rate will be very low, and most ads will not display on the site.
Additional Information: If you are just learning about Ads.txt, step-by-step instructions for creating a new ads.txt file for your site are available in this informative video and on the IAB TECH LAB Ads.txt page.
*The ads.txt file MUST be on secure page (https), which are prioritized by crawlers over non-secure pages (http). Ads.txt files on subdomains (“including www.“) apply only to that subdomain, and we recommend placing the ads.txt file only on the primary domain.
**If you use a text editor to compile your list, make sure to use one that allows you to save your ads.txt file with Unix/LF (Line Feed) line breaks. BBEdit for Mac and current versions of Window Notepad will support Unix/Linux line endings (LF). Additionally, use an ads.txt validator to confirm that your file has been formatted properly once live. We recommend copying your live ads.txt url and pasting it into the “Enter ads.txt URL” section of https://adstxt.guru/validator/. This tool will highlight any errors so that you can find/fix them quickly and efficiently.
