Ads.txt Checker is a free Chrome add-on developed by yuttasat. This add-on allows users to easily determine if a website is utilizing an ads.txt file, which lists the authorized digital sellers for that site. By simply clicking on the icon, users can view a pop-up window that displays all the authorized digital sellers for the website in question.

The IAB (Interactive Advertising Bureau) has initiated the ads.txt initiative as a means to combat fraud and misrepresented domains. This initiative requires publishers to list their authorized digital sellers in an ads.txt file, ensuring transparency and accountability in digital advertising.

Ads.txt Checker provides a convenient way for users to verify if a website is adhering to this initiative. By quickly accessing the list of authorized digital sellers, users can have confidence in the legitimacy of the website's advertising practices.

With its user-friendly interface and valuable functionality, Ads.txt Checker is a useful tool for anyone involved in digital advertising or looking to ensure the credibility of a website's advertising partners.
