SEO Lens: On-Page SEO, GEO & AI Crawler Checker

Overview

SEO Lens runs a complete analysis of any webpage right in your browser, scoring on-page SEO on a 0-100 scale with clear pass/fail checks. It covers technical SEO (title, meta description, robots, canonical URL, indexability), H1-H6 heading structure, keyword density, internal/external link audits, image analysis, Open Graph previews, JSON-LD structured data, and a readiness score for AI crawlers (GEO). Everything runs locally — nothing about the page is ever uploaded to a server.
