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: http://domain.com/ads.txt and 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.
Ads.txt Validator: 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.
Visit our Ads.txt Troubleshooting Guide for additional information on common reasons your ads.txt file may not be programmatically readable.
