How the SEO Analyzer Works

Enter a URL and our tool fetches the page via a proxy, then parses the HTML to check 19 on-page SEO factors. Each check is categorized as Critical, Important, or Suggestion and scored as pass, warning, or fail.

What Is Checked

Title tag — Presence and length (30–60 characters recommended)
Meta description — Presence and length (120–160 characters recommended)
H1 heading — Exactly one H1 should exist
Heading hierarchy — Logical H1 → H2 → H3 structure
Canonical URL — Prevents duplicate content issues
Canonical self-reference — Flags if canonical differs from page URL
Viewport meta tag — Required for mobile responsiveness
Meta robots — Detects noindex / nofollow directives
HTTP status — 200 OK, redirect, or error code
HTTPS — Warnings if page is served over HTTP
JSON-LD Schema — Structured data detection and type identification
Open Graph tags — Controls how links appear when shared on social media
Twitter Card tags — Controls how your page appears in tweets
Image alt text — Accessibility and SEO for images
Internal & external links — Helps search engines discover content
Content length — Word count for ranking potential
Language attribute — lang on the <html> element
Favicon — Brand recognition in browser tabs
SPA detection — Warns if page is JavaScript-rendered

Limitations

This is a client-side tool that fetches the raw HTML via a CORS proxy. It cannot measure page speed, server response times, HTTPS configuration, or crawl depth. For a full SEO audit, use this tool alongside Google Search Console, Lighthouse, and dedicated SEO platforms.
