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

About

Run an on-demand SEO and GEO audit of any webpage in one click.

SEO Lens helps SEO specialists, content teams, marketers, and developers understand how a webpage appears to search engines, social platforms, and AI-powered discovery systems. Analysis starts only when you click the extension and is performed locally in your browser. Page content and report results are not uploaded to the developer or a developer-operated server.

SEO Lens does not continuously monitor browsing, run background page scans, collect browsing history, include advertising or analytics trackers, or require an account or API key. It uses temporary access to the active tab rather than broad access to every website.

🔍 SEO OVERVIEW

• Get an instant 0–100 on-page SEO score.
• See 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 authoritative search 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 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 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, destination URL, and nofollow status.
• Filter lists to focus 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 when shared across major social and professional networks.
• Inspect Open Graph and social card metadata in separate sections.
• Open supported sharing-debugging tools when a 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 whether site directives allow or restrict common AI search and model-training crawlers.
• Review signals related to answer extractability, evidence, 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

• Analysis is user-initiated and limited to the active tab.
• The extension does not request broad host permissions.
• Analyzed page content and report results remain on the device.
• The developer cannot access the pages or reports you analyze.
• No telemetry, analytics SDK, advertising tracker, account, or API key is used.
• No browsing history or analyzed page content is retained.
• Only the selected interface language is saved in local extension storage.

These controls make SEO Lens suitable for review in managed browser environments. Organization administrators can approve or deploy the extension through standard enterprise browser policies.

🌍 LANGUAGES

The interface is available in English, Vietnamese, Spanish, Hindi, and Simplified Chinese.

SEO Lens is designed for fast, practical page reviews. Open any HTTP or HTTPS webpage, click the extension icon, and immediately see what is working and what should be improved for search engines, social sharing, and AI-powered discovery.
