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

• MozBar — Toggle MozBar on to enable the metrics bar at the top of your browser. Here you can see link metrics and authority metrics as you browse.
• SERP Overlay and Search Features — Toggle SERP Overlay on to see link and authority metrics right in the SERP as you search in Google

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

When MozBar is toggled on in the settings menu, the MozBar docked metrics bar will be activated. You can use this to see key authority metrics and link metrics for sites and pages as you browse the web.

Within the metrics bar, there are three primary groups of metrics: domain-level metrics, page-level metrics, 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.
• Links (i.e. inbound links) — An incoming link from a page on another website back to this page.
• Keywords (i.e. ranking keywords) — The number of keywords this page is currently ranking for based on Keyword Explorer’s Explore By Site feature.

Brand Authority

• Brand Authority (BA) -  A score developed by Moz that measures a domain’s total brand strength as a 1-100 score.

Click on any of the metrics in the MozBar metrics bar to be taken to Moz Pro where you can dive deeper and further analyze the data.

When SERP Overlay and Search Features is toggled on in the settings menu, SERP overlay will be activated when you search in Google. This feature will show you key metrics for all the organic results in the SERP, as you scroll and browse.

Within the MozBar Serp Overlay you will see the following data:

• 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. And you can export your search results using the Export SERP button on the top left.

With MozBar active on a search engine, you can create profiles to make custom searches by country or region. Setting up a new search profile in MozBar is as easy as 1-2-3.

1. Head to the MozBar browser extension pop-out window.

2. Click Settings.

3. Click Add profile under Search Profiles.

From the Search Profile creation window, you can select the following information to customize your search:

• Search engine
• Country
• Region
• Search profile name

Once you have made your selections, click Save profile, and you can start using your new search setting right away. 

To activate your newly created Search profile in the search results, make sure you have MozBar activated from your settings menu and then select the Search profile from the available drop-down. Pro tip: Not seeing your newly created profile? Try refreshing the page!

Once you select your Search profile, your search engine's results page (SERP) should reload to reflect that newly selected option. 

You can also export your search results using the Export SERP button on the top left.

In the example below, the followed and external link highlight options are toggled on. Any links highlighted in green are follow links. Any highlighted in blue are external links. If a link has 2 colors like the “Help” link on this page, that means the link meets 2 link highlight criteria. In this case, it is both a followed link and an external link.

MozBar offers customizable features such as 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 or from the Settings menu within the extension window.

Dark mode

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

To change the docking location of MozBar, click Dock to bottom. 

If you ever need to change the location again, simply click the same button to move the MozBar.

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. https://moz.proxybugs.com/help/*).
