Free SEO Tool

Meta Tag Analyzer

Enter any URL to analyze its meta tags, Open Graph, Twitter Cards, Schema.org, hreflang, and more — exactly like the Lumina extension.

How this tool works

This tool fetches any public URL and analyzes all SEO-relevant meta tags — title, description, canonical, robots, Open Graph, Twitter Cards, Schema.org JSON-LD, hreflang, viewport, charset, and more. Results are identical to what the Lumina Chrome Extension shows in its Overview tab.

For a deeper analysis including HTTP headers, X-Robots-Tag, broken links, heading highlighting, and JS vs No-JS comparison, install the free Lumina Chrome Extension.
