Every check that matters for ranking in Google, Bing, and AI-powered search engines — all free, all in one dashboard.
Title tag length and keyword placement, meta description quality, H1–H3 heading structure, canonical URL validation, meta keywords, keyword density. The signals Google reads on every crawl.
Robots.txt accessibility, XML sitemap presence and validity, character encoding, hreflang implementation, robots meta directives, server technology detection. The foundation that lets search engines crawl and index correctly.
Word count benchmarking, internal link count and anchor text analysis, external link review, text-to-HTML ratio. Signals that tell Google whether a page has genuine depth and authority.
Real LCP, INP, and CLS scores from the Google PageSpeed API — not estimates. Plus TTFB, total page size, GZIP/Brotli compression, and browser caching. Core Web Vitals are an official Google ranking signal.
HTTPS/SSL validation, X-Frame-Options, HSTS, CSP, X-Content-Type-Options, Referrer-Policy. Security signals that Google uses as ranking factors and that build user trust.
Open Graph tags, Twitter Card implementation, Schema.org structured data types, Favicon presence. Rich data that influences CTR and enables rich results in Google Search.
Image alt text coverage, ARIA label implementation, HTML lang attribute. Accessibility factors that overlap directly with SEO — Google's crawler processes pages similarly to assistive technologies.
Viewport meta tag, mobile-friendly detection, tap target size validation. With Google's mobile-first indexing fully active, mobile readiness is the primary ranking context.

SEO Inspector Hub was built by practising SEO consultants and agency owners who were frustrated by tools that check 5–10 factors, watermark every report, and push you toward an expensive subscription. We built the tool we wanted to use ourselves — and made it completely free.
Every check reflects real-world ranking factors verified against Google's documentation and confirmed algorithm updates. Our AEO and GEO scoring modules were developed specifically for the AI search landscape of 2025–2026 — covering how your content performs in AI Overviews, ChatGPT, and Perplexity.
Core Web Vitals data is pulled live from the Google PageSpeed Insights API — not cached estimates — so every performance score reflects Google's actual measurement of your page at the time of audit.
