Three simple steps to audit your website and get a complete SEO action plan.
Paste any website URL into the audit field. Works on your own site or any competitor — no signup, no extension, no setup.
Our engine crawls your site, audits technical SEO, measures Core Web Vitals, scores content quality, and validates security headers in under 60 seconds.
Receive a complete site health score with prioritized fixes — severity, impact, and step-by-step instructions for every issue found.
90+ checks across four critical SEO dimensions — in one free, AI-powered audit.
Audits meta tags, canonicals, hreflang, schema markup, sitemap.xml, robots.txt, HTTPS, redirects, and indexability — 26 technical checks per page.
Measures LCP, CLS, and INP estimates, detects render-blocking resources, oversized images, and missing caching headers.
Scores content depth, readability, keyword usage, heading hierarchy, alt text coverage, and author/E-E-A-T signals against Google's guidelines.
Finds broken internal links, audits external links, maps your internal link graph, and flags orphan pages hurting crawlability.
Validates HTTPS, security headers (HSTS, CSP, X-Frame-Options), mixed content, and WCAG accessibility issues like color contrast.
Every check runs against the mobile rendering of your pages — the version Google uses for indexing and ranking decisions.
Every issue is ranked by severity (Critical / Warning / Info) and impact (High / Medium / Low) — so you know exactly what to fix first.
Each issue includes a clear, actionable "How to fix" recommendation — written for marketers, not just developers.
Most ranking problems hide in plain sight — slow pages, broken links, thin content, missing schema, weak E-E-A-T signals. A complete audit surfaces every silent issue before it costs you traffic, conversions, and revenue.

A site audit tool systematically crawls a website and evaluates it against hundreds of SEO, performance, content, and security signals — surfacing the exact issues hurting your rankings. Without a regular audit, technical debt accumulates silently: meta tags rot, schema breaks, pages slow down, and links die — and Google notices long before you do.
AI Ranko's free SEO auditruns 90+ checks across four critical dimensions — technical SEO, Core Web Vitals, content quality, and security — and delivers a prioritized action plan in under 60 seconds. Every issue includes severity, impact, and a clear "how to fix" recommendation written in plain English.
Unlike Semrush or Ahrefs, there's no monthly limit, no per-audit charge, and no learning curve. Unlike Screaming Frog, there's nothing to install and no system resources eaten. It runs entirely in your browser, stores no data, and delivers a complete website health check the moment you paste a URL.
Whether you're auditing your own site, benchmarking a competitor, or preparing a client report, AI Ranko gives you the same depth as paid enterprise tools — without the price tag or complexity. It's the fastest, most complete technical SEO audit tool available online in 2025.
