Ads.txt Validator

Ensure your domain is protected from spoofing. Our validator checks if your ads.txt file is correctly implemented and reachable by crawlers.

What is Ads.txt?

Authorized Digital Sellers, or ads.txt, is an IAB Tech Lab initiative that helps ensure that your digital ad inventory is only sold through sellers (such as AdSense) who you've identified as authorized.

Creating your own ads.txt file gives you more control over who's allowed to sell ads on your site and helps prevent counterfeit inventory from being presented to advertisers.

How to Implement?

1 Create a text (.txt) file named ads.txt
2 Include your publisher ID (e.g., pub-0000...)
3 Upload to your root directory

Ensure the file is uploaded to the root directory of your site. It should be accessible at yourdomain.com/ads.txt. Check if your server configuration isn't blocking .txt files.
