MozBar

Once you install the free Chrome extension, a toolbar will appear at the top of your browser or search results. When you visit any website, MozBar automatically displays the site's Domain Authority (DA) and Page Authority (PA) on a scale of 1 to 100. A higher score indicates a greater ability to rank on search engines based on Moz's proprietary metrics.

You can download and use MozBar for free to see basic DA, PA, and link metrics directly on the page. However, if you want to access advanced features like keyword difficulty scores or in-depth backlink analysis, you will need to log in with a premium Moz Pro account. The paid subscription unlocks a much deeper layer of SEO data.

Yes, MozBar includes an overlay feature that allows you to visually highlight internal, external, followed, and no-followed links on any page. This is highly useful for conducting quick SEO audits or finding broken link-building opportunities. You can toggle this visual overlay on and off directly from the extension's main menu.

Yes, when you perform a search on Google, MozBar injects a data block under every single search result. This block instantly shows you the DA, PA, and the number of linking root domains for each competing webpage. It is an incredibly efficient way to gauge the ranking difficulty of a keyword before you decide to target it.
