Website Grader

Check on-page SEO, response headers and content structure, plus a mobile PageSpeed lab score when available. These automated checks flag possible issues; they do not replace a full audit.

What This Tool Checks

SEO (40% of grade)

Title tag, meta description, heading structure, canonical tags, Open Graph meta, structured data, image alt text, and indexability.

Performance (30% of grade)

Google PageSpeed Insights mobile Lighthouse lab score. This is a simulated performance test, not proof of field Core Web Vitals. Missing data leaves the overall grade incomplete.

Security (20% of grade)

HTTPS usage, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security headers.

Content (10% of grade)

Word count, internal and external link count, image count, and heading diversity to assess content depth and structure.
