What it really isMozBar — Moz's free Chrome SEO toolbar with optional premium metrics via Moz Pro.
Our takeMozBar is a well-established free Chrome extension that overlays Domain Authority, Page Authority, Spam Score, link metrics, and on-page SEO data on any page or SERP — no login required for core metrics.
It is freemium: the free tier is useful, while MozBar Premium (deeper link analysis, additional SEO data) requires an active Moz Pro subscription starting at $39/mo (annual).
Why we rate itMozBar's free tier punches above its weight: instant DA/PA on any page with no account needed is a genuine time-saver for daily SEO work.
The extension has been the industry's go-to quick-check tool for over a decade, and Moz's authority metrics remain a lingua franca across SEO teams.
The catchPremium features are gated behind a Moz Pro subscription, and Moz's proprietary DA/PA metrics can diverge from Ahrefs DR or Semrush AS — meaning teams relying on multiple tools may see conflicting scores.
The free tier also has no historical trend data.

Best / not good for

Best for
  • Quick competitive DA/PA checks on SERPs without leaving the browser
  • Content researchers auditing on-page SEO elements (headings, meta tags) on the fly
  • SEO teams already subscribed to Moz Pro who want instant metrics in the browser
Not good for
  • In-depth backlink audits that need full crawl data and historical trends
  • Teams preferring a single authority metric sourced from Ahrefs or Semrush ecosystems
  • Large-scale bulk domain analysis (the toolbar is page-by-page, not batch)
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: install from Chrome Web Store, visit any page, and DA/PA metrics appear immediately — no account required for core features.
  2. Scale breakpoint
    Breaks at scale: the toolbar is designed for single-page spot-checks; bulk or automated metric collection requires Moz Pro's API or full platform tools.
  3. Walled garden
    Moderate: all metrics are Moz-proprietary (DA, PA, Spam Score); deeper analysis and historical data are locked to Moz Pro, creating upgrade pressure as needs grow.
Still a fit?
If none of these block you, start on the free plan.
