Why ads.txt matters
ads.txt is a public list of the companies allowed to sell ads on your website. Advertisers check it before they buy, so a missing or broken file can mean fewer bids and lower earnings, and in Google AdSense it triggers an “Earnings at risk” alert. Most problems come from small mistakes: a wrong folder, a typo in a publisher ID, a server that returns a web page instead of the file. Our tools find these in seconds, and our guides explain how to fix them on WordPress, Blogger and common hosting panels.
