Frequently asked questions
Is the Domain Authority Checker extension free?
Yes. It's completely free to install and use from the Chrome Web Store, with no signup required to see a domain's rating.
What is Domain Authority / Domain Rating (DR)?
It's a 0–100 score that estimates a website's backlink authority — higher is stronger. Our extension shows this rating for any site you visit and for Google search results.
Where does the score come from?
The extension looks up the domain's rating from the Open PageRank API. It sends only the domain name (e.g. example.com) — never full URLs, page content, cookies, or personal data.
Does it work on Google search results?
Yes. On Google search pages it reads the domains of the results and shows an authority badge next to each one, so you can compare pages at a glance.
Does it store or track my data?
No. Nothing is stored on our servers and there is no analytics or tracking in the extension. The only data saved is an optional API key you can enter, kept locally in your browser.
Which browsers are supported?
It's a Chrome extension, so it works on Chrome and other Chromium browsers such as Brave, Edge, and Arc.
