Free Website SEO Audit Tool

Enter any URL to get a comprehensive SEO analysis with actionable recommendations. Our AI-powered audit checks 50+ ranking factors covering technical SEO, on-page optimization, content quality, and Core Web Vitals in under 30 seconds.

How to Use This SEO Audit Tool

Step 1: Enter a URL or Paste HTML

Type any website URL into the input field or paste raw HTML source code (Ctrl+U to view source). Pasting HTML enables deeper checks on meta tags, canonical tags, heading hierarchy, and structured data.

Step 2: Review Your Score

See your overall SEO score (0-100) broken into four dimensions: Technical SEO, On-Page SEO, Content Quality, and Mobile & Speed. Each finding is tagged P0 (critical), P1 (important), or P2 (optimize).

Step 3: Follow the Action Plan

Start with P0 items — they block indexing. Then P1 (ranking impact), then P2 (competitive edge). Most sites resolve critical issues in a single afternoon.
