MozBar is your ultimate SEO research assistant, offering link data, ranking keywords information, and overviews of on-page factors. In addition to everything it offers in the popout window, this handy tool has there more features that can be toggled on and off via the Settings menu.

• Page Toolbar — Toggle the Toolbar on to enable the metrics bar at the top of your browser. As you browse, you can see link and authority metrics.
• Search Results Overlay — Toggle SERP Overlay on to see link and authority metrics right in the SERP as you search in Google.
• Link Highlights — Toggle Link Highlights on to show colored highlights of the links on a page, based on their type. 

We’ll cover each of these features in-depth below.

When Page Toolbar is toggled on in the settings menu, the MozBar metrics bar will be activated and docked based on your settings. You can choose to have the bar at the top, bottom, right, or left of your browser window.

The toolbar lets you view key authority and link metrics for sites and pages as you browse the web.

In the metrics bar, there are three primary groups of metrics: domain-level, page-level, and Brand Authority.

Domain-level metrics

The domain-level metrics available in the MozBar metrics bar include:

• Domain Authority (DA) — A Moz proprietary metric from 1 to 100 that predicts how well a domain will rank in Google based on a machine learning algorithm of link metrics.
• Domains (i.e. linking domains) — The number of unique root domains linking to this page’s root domain. Two links from the same website will only be counted as one linking root domain. 
• Links (i.e. inbound links) — An incoming link from a page on another website back to this domain.
• Keywords (i.e. ranking keywords) — The number of keywords this domain is currently ranking for based on Keyword Explorer’s Explore By Site feature.
• Spam Score — Represents the percentage of sites with similar features we've found to be penalized or banned by Google. This does not mean that the site is spammy. It’s best to use this as a guide to potentially spammy sites for further investigation.

Page-level metrics

The page-level metrics available in the MozBar metrics bar include:

• Page Authority (PA) — A Moz proprietary metric from 1 to 100 that predicts how well a page will rank in Google based on a machine learning algorithm of link metrics.
• Domains (i.e. linking domains) — The number of unique root domains linking to this page. Two links from the same website will only be counted as one linking root domain.

• Domain Authority (DA) — A Moz proprietary metric from 1 to 100 that predicts how well a domain will rank in Google based on a machine learning algorithm of link metrics.
• Page Authority (PA) — A Moz proprietary metric from 1 to 100 that predicts how well a page will rank in Google based on a machine learning algorithm of link metrics.
• Domains (i.e. linking domains) — The number of unique root domains linking to a target. Two links from the same website will only be counted as one linking root domain. In SERP Overlay, you will see a count for both page and domain-level linking domains.
• Links (i.e. inbound links) — An incoming link from a page on another website back to this page or site. In SERP Overlay, you will see a count for both page and domain-level linking domains.

Clicking any of these metrics will take you to Link Explorer, where you can explore this data further. 

You can also export your search results using the Export SERP button of the toolbar. Please note: you will need to enable the toolbar in order to see the export button. To learn how to enable the toolbar, please see above.

MozBar offers customizable features, including dark mode, dock location, and a block list. If you ever want to update how your MozBar interacts with sites or how it feels, you can do so from the MozBar itself (see the toolbar section of this article) or from the Settings menu within the extension window.

The Settings menu is also where you can toggle on the Page Toolbar, Search Results Overlay, and Link Highlights functions.

Dark mode

MozBar offers Dark and Light modes. To change the selected mode, you can either use the toggle option when the MozBar is activated or head to Settings > Appearence.

Dock to bottom/top

If you find that the MozBar is blocking the top of the site you’re visiting, you can choose to move it to the bottom, left, or right of the page. You can adjust this in the toolbar itself or in the popout window under Settings > Page Toolbar > Toolbar Position.

Excluded Domains

The Excluded Domains list feature in MozBar allows you to choose where MozBar shows up and where you use your queries. You can add domains, pages, or subfolder paths to disable MozBar on frequently visited websites for which you don’t want to see MozBar data. Use an asterisk/wild card (*) at the end of a URL path to block all pages in that subfolder (e.g. /help/*). 

To update your Excluded Domains list, head to Settings > Page Toolbar > Excluded Domains.
