mozbar vs detailed-seo-extension
MozBar vs Detailed SEO Extension — features, pricing, and which to choose for your SEO workflow in 2026.
Quick Verdict
When choosing between MozBar and Detailed SEO Extension, you're picking between two fundamentally different approaches to browser-based SEO analysis. MozBar focuses on authority metrics and competitive intelligence, while Detailed SEO Extension specializes in technical on-page analysis and markup validation.
The core difference comes down to what you need most: MozBar excels at showing you domain and page authority scores, backlink data, and SERP analysis directly in your browser. Detailed SEO Extension strips away the competitive metrics to focus purely on technical SEO elements like schema markup, canonical tags, and hreflang implementation.
Feature Comparison
MozBar's strength lies in its integration with Moz's massive link database. You get instant Domain Authority and Page Authority scores, can see the top linking domains to any page, and analyze SERP results with authority metrics overlaid directly on Google search pages. The spam score feature helps identify potentially problematic sites, and the keyword highlighting shows how well pages target specific terms. Detailed SEO Extension takes a completely different approach, functioning more like a technical audit tool. It extracts all heading structures (H1-H6), displays meta titles and descriptions with character counts, shows canonical URLs and hreflang tags, and validates schema markup implementation. You can quickly spot duplicate meta descriptions, missing alt tags, or improperly implemented structured data without opening developer tools. The key difference is depth versus breadth: MozBar gives you competitive intelligence but limited technical details, while Detailed SEO Extension provides comprehensive on-page analysis but no authority metrics or backlink data.
Pricing Comparison
Both tools are completely free, making this comparison purely about functionality rather than cost. MozBar requires no account creation for basic features, though linking to a Moz Pro account (starting at $179/month) unlocks additional data like more detailed link metrics and keyword difficulty scores. Detailed SEO Extension is entirely free with no premium upsells or account requirements. This makes it particularly attractive for freelancers or small agencies who need technical SEO analysis without ongoing software costs.
Best For
MozBar is the better choice when you need competitive intelligence and authority metrics. If you're doing competitor research, analyzing SERP landscapes, or need to quickly assess the authority of potential link targets, MozBar's Domain Authority and backlink preview features are invaluable. It's also better for content teams who want to see how their pages stack up against competitors in search results. Detailed SEO Extension is superior for technical SEO audits and on-page optimization. Choose this if you're regularly checking meta tag implementation, validating schema markup, or ensuring proper canonical and hreflang setup. It's particularly useful for developers and technical SEOs who need to quickly diagnose on-page issues without switching between multiple tools.
The Verdict
For most SEO professionals, MozBar provides more actionable data for day-to-day work. The ability to quickly assess domain authority and see competitive metrics directly in SERPs makes it more versatile for research and strategy. However, if your work focuses heavily on technical SEO implementation and you already have authority metrics from other tools, Detailed SEO Extension's comprehensive on-page analysis makes it the more specialized choice. Since both are free, the smartest approach is installing both and using each for their specific strengths.
