Why it matters

If you are a Publisher, ads.txt will help you to:

Retain control over who sells your inventory

Improve the quality of the ads shown

Block unauthorized arbitrage and improve the overall user experience of your website.

Furthermore, complying with this initiative will show advertisers that your website is trustworthy and brand safe for their ads.

60% of the comScore 1000 publishers have already implemented ads.txt on their sites and this percentage will only increase

Publishers who are ads.txt compliant will be able to sell their inventory in curated markets - today major DSPs are already giving the option to advertisers to filter-out inventory that is not ads.txt certified
