Free SEO Checker & Score Generator

SeoFightr crawls two public URLs and generates a comparable SEO report for each. The generator scores five classic search signal groups and turns them into a single 0-100 number so the result is readable at a glance:

• Speed — render and load behaviour that Core Web Vitals reward.
• Crawlability — robots rules, indexability, canonical and sitemap health.
• Structure — heading hierarchy, semantic HTML, metadata and schema markup.
• Links — internal linking depth and external authority signals.
• Mobile — responsive rendering and mobile-first usability.

Every group is shown for both domains, so an SEO detect run is also a competitive gap analysis rather than a generic checklist.

Classic rankings are only half the picture now. A growing share of research traffic never reaches a blue link: people ask ChatGPT, Gemini, Perplexity or Copilot and read a synthesised answer. SeoFightr therefore adds a second 0-100 score for generative engine optimization (GEO): extractability, evidence, entity identity, question coverage and citability.

You can run the AI-visibility half on its own from the AI search visibility checker.
