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.
