SEO Lens: On-page SEO & GEO audits for any page, in your browser

Why you need a lightweight SEO audit tool

Auditing a page's SEO usually means opening several different tools, not to mention uploading the page's content to a third-party server. SEO Lens bundles all of that into one extension that runs entirely inside your browser.

What SEO Lens checks

With a single click, SEO Lens scores on-page SEO on a 0-100 scale with a clear pass/fail checklist. It covers technical checks (title, meta description, robots, canonical URL, indexability), H1-H6 heading structure, keyword density across the title/headings/body/images/URL, internal and external link audits with anchor text, image checks (dimensions, alt text), Open Graph previews for social platforms, and JSON-LD structured data.

GEO readiness for AI crawlers

The biggest differentiator: SEO Lens also includes GEO Readiness — a separate score for how well a page is set up for AI crawlers, an increasingly important signal as people search through AI. Every analysis runs on your machine; no page content or report is ever sent to a server. SEO Lens is free and supports English, Vietnamese, Spanish, Hindi, and Simplified Chinese.
