Overview

Product summary

Review the store description, core capabilities, and common use cases.

Adstxter is a lightweight tool that detects missing sellers in ads.txt files with a single click. It runs tests on your currently open website to check for specified sellers.

Define test sellers in the Adstxter window's input field. Your entered sellers are saved between browser sessions until you replace or remove them.

The extension remains completely inactive when its window is closed, ensuring zero system resource usage and no interference with your browsing experience.

Testing follows the IAB Tech Lab's ads.txt specification. Note that checking ads.txt files on subdomains is not currently supported.
