MozBar vs SEOquake 2026: Which Free SERP Overlay Wins?
Both are free SERP overlays — but they use different data sources, show different metrics, and suit different workflows. Here's a complete breakdown.
MozBar: best for DA/PA link buildingSEOquake: best for free data volume
Editor's Verdict
SEOquake wins on pure free value — it shows more metrics with no account required, exports to CSV, and covers more use cases. MozBar wins for DA/PA familiarity — if your workflow revolves around Moz's authority scores for link qualification, the always-visible DA/PA overlay is unmatched. Don't run both simultaneously: the SERP overlay conflict degrades the experience.

Data Source Difference
MozBar uses Moz's link index for DA/PA. SEOquake uses Semrush's database for Authority Score and traffic estimates. These are different indices with different methodologies — scores from one don't map directly to the other. For most use cases this doesn't matter; both are directional authority indicators, not Google ranking factors.
If your agency or client communicates in "DA" as a benchmark, MozBar is the right choice purely for consistency of language. If you're doing fresh, data-led research, SEOquake's broader free dataset is more useful.
Frequently Asked Questions
SEOquake offers more free data overall (SERP overlay, on-page audit, CSV export, no account needed). MozBar's DA/PA is preferred for link-building workflows where Moz's authority score is the established benchmark. For most SEOs starting fresh: SEOquake first, MozBar second.
Yes — running both simultaneously causes SERP overlay clutter. Keep SEOquake as default; enable MozBar only for link prospecting sessions.
