SEO Inspector EN

SEO Inspector gives you a complete SEO report for any web page in one click. It checks the title and meta description with character-length guidance, canonical and robots tags, hreflang alternates, heading structure, Open Graph and Twitter Card tags with live image previews, favicons and touch icons, JSON-LD structured data with per-type validation, word count and keyword density, image alt text, mixed content, and URL structure. Every page gets a 0–100 score, results can be exported as Markdown, CSV, or JSON, and recent analyses are kept in a local history. Use it as a popup or keep it open in the sidebar, where it re-analyzes automatically as you browse. Everything runs entirely on your device — no accounts, no data collection, no remote servers.
