SEO Lens: On-Page SEO, GEO & AI Crawler Checker Edge extension security report

Run a complete on-page SEO and GEO audit of the page you are viewing in one click. SEO Lens helps SEO specialists, content teams, marketers, and developers understand how a webpage appears to traditional search engines, social platforms, and AI search crawlers. It turns page data into clear scores, issue indicators, and practical recommendations without requiring an account or API key. 🔍 SEO OVERVIEW • Get an instant 0–100 on-page SEO score. • See exactly which checks passed and which items need improvement. • Receive a critical warning when a page contains a noindex directive. • Open actionable guidance with links to official Google documentation. ⚙️ METADATA AND TECHNICAL SEO • Inspect the title and meta description using both character count and estimated pixel width. • Check robots directives, canonical URL, page language, keywords, and word count. • Detect whether the page can be indexed by search engines. • Check the default robots.txt, sitemap.xml, and llms.txt files for the current site. 📝 HEADINGS AND CONTENT • Review the complete H1–H6 structure with visual hierarchy indentation. • See heading totals by level for a quick structural overview. • Identify empty headings and review the content of every heading on the page. 🎯 KEYWORD DENSITY • Analyze a target keyword or exact phrase in the main article content or the entire page. • Measure occurrences, density, and important on-page placements. • Check the title, meta description, H1, subheadings, URL, first 100 words, body content, and image alt text. • Explore the most frequent one-word, two-word, and three-word phrases with common stop words excluded. 🔗 LINK AND IMAGE AUDITS • Separate internal and external links into focused tabs. • Review anchor text, URL, and nofollow status. • Filter lists to focus only on links that need attention. • View image thumbnails, dimensions, source URLs, and alt text status. • Open images externally or preview them at full size inside the extension. 📱 SOCIAL SHARE PREVIEWS • Preview how the page may appear on Facebook, LinkedIn, Zalo, and X/Twitter. • Inspect Open Graph and Twitter Card metadata in separate sections. • Open Facebook and Zalo debugging tools directly when a sharing preview needs to be refreshed. 🧩 STRUCTURED DATA • Detect JSON-LD structured data on the current page. • Inspect nested schema properties in a readable, indented view. • Identify invalid JSON-LD blocks. • Export detected schema as a JSON file for further review. 🤖 GEO AND AI SEARCH READINESS • Get a separate 0–100 GEO readiness score based on observable page signals. • Check access rules for ChatGPT, OpenAI, Claude, Anthropic, Google AI, and Gemini crawlers. • Review signals related to answer extractability, evidence and trust, entity understanding, discovery, and content freshness. • Detect authorship, content dates, supporting sources, quantitative claims, question headings, lists, tables, entity schema, and sameAs references. • Treat llms.txt as an optional experimental signal without using it to reduce the GEO score. 🔒 PRIVATE BY DESIGN SEO Lens analyzes the active page locally in your browser.
