MozBar is Moz's SEO extension for Chrome. Guest mode shows on-page elements and link details for free, a free Moz Community account adds Domain Authority and Page Authority, and Moz Pro unlocks Spam Score and more.
MozBar puts Moz’s link metrics and an on-page checker into Chrome. Its Chrome Web Store listing describes it as completely re-engineered.
Main features
- Authority metrics: Domain Authority (DA), Page Authority (PA) and Brand Authority for the page you are viewing.
- On-page highlighter: identify and categorise links on a page.
- Technical checks: schema markup, hreflang tags, robots.txt and sitemaps.
- SERP analysis: compare link metrics on search results pages and export them to CSV.
- Keyword and content insights from Moz Pro data.
Guest, Community and Pro
According to the listing:
- Guest (free): on-page elements, general attributes and internal link details.
- Community (free account): everything in Guest mode plus DA and PA.
- Moz Pro subscribers: Spam Score, Page Optimization, domain analysis and keyword ranking queries.
The developer has disclosed that it will not collect or use your data.
Installing MozBar
- The Download button opens the official MozBar listing on the Chrome Web Store.
- Click Add to Chrome and confirm.
- Create or sign in to a free Moz account if you want DA and PA.
Good to know
Domain Authority is Moz’s own score, not a Google metric, so use it to compare sites rather than as a ranking factor. For a second set of metrics, compare with the Ahrefs SEO Toolbar; for free on-page checks from Semrush, see SEOquake.
Pros
- DA and PA with a free Moz account
- On-page and technical checks on any page
- CSV export from search results
Cons
- Spam Score and keyword data need Moz Pro
- Authority scores are Moz estimates, not Google data
Frequently Asked Questions
Is MozBar free?
Partly. Guest mode is free, and a free Moz Community account adds Domain Authority and Page Authority. Spam Score and other advanced data require Moz Pro.
Is Domain Authority a Google ranking factor?
No. Domain Authority is a score calculated by Moz. It is useful for comparing sites, but it is not a metric Google uses.
