How It Works

This tool parses your HTML and evaluates it against a comprehensive on-page SEO checklist. All processing happens entirely in your browser — no data is sent to any server.

Checklist Categories
  • Title & Meta — Title tag length, meta description, charset, and viewport
  • Headings — H1 presence and count, heading hierarchy, keyword placement
  • Images — Alt text coverage, descriptive filenames, lazy loading
  • Links — Internal links, external link attributes, descriptive anchor text
  • Social & Open Graph — OG title, description, image, and Twitter Card tags
  • Structured Data — JSON-LD or Microdata schema markup presence
  • Technical SEO — Canonical URL, language attribute, mobile viewport, clean URLs
  • Content Quality — Word count, semantic HTML, content-to-code ratio
Scoring

Each check is weighted equally. Passes score full points, warnings half, and failures zero. The final percentage determines the grade:

ScoreGrade
80 – 100%SEO-Optimized
50 – 79%Needs Improvement
0 – 49%Poor SEO
Tip: This checklist analyzes static HTML source code. For a complete SEO audit, also check page speed, mobile usability, backlink profile, and search console data.
