SEO Lens — On-Page Audit

SEO Lens shows you how any webpage is set up for search, without sending a single byte anywhere. Open the side panel on any page and scan it. You get: A preview of how the page's title and description will appear in search results, truncated exactly as a search engine would truncate them Title and meta description length checks against the lengths that actually display A full heading outline, with skipped levels flagged Canonical URL and indexability checks, so you catch a stray noindex before it costs you traffic Image checks for missing alt text and missing width/height, the two most common causes of accessibility gaps and layout shift Internal and external link counts, plus link text that says nothing useful Structured data detection, including JSON-LD blocks that fail to parse and are silently ignored Open Graph and Twitter card completeness, so shared links do not render as bare URLs Loading measurements taken from the page itself: largest paint, layout shift, time to first byte, DOM size Everything is measured on the page in front of you. There is no account, no subscription, no server, and no tracking. Close the browser and nothing is kept.
