MozBar is a free Chrome extension developed by Moz that displays instant SEO metrics like Domain Authority, Page Authority, and link data directly on any webpage or Google search result. Instead of switching between tools, you can see authority metrics, on-page data, and link types in real time as you browse.
It’s widely used by SEOs, SaaS marketers, link builders, and digital PR teams who need quick evaluations of domains and pages before outreach or competitive research.

MozBar acts like an overlay that shows SEO data while you’re on a webpage or looking at search results. Once installed, you can turn it on or off with one click.
Here’s what it helps you see:
- DA & PA scores for any website or page
- Followed vs. nofollowed links highlighted visually
- Anchor text analysis
- Spam indicators
- Title tags, meta descriptions, headings, and schema data
- Exportable SERP metrics (useful for keyword research)
- Page load optimization checks (for pro users)
These instant insights make MozBar valuable for beginners and pros alike.
