Rank well in search engines. Get cited by AI.

DiagnoSEO runs a cRank well in search engines. Get cited by AI.

DiagnoSEO runs a complete on-page SEO and GEO (AI-search) audit on any page in one click. It analyzes the page you're viewing and gives you a clear 0-100 score plus specific, actionable issues - all processed locally in your browser, with zero tracking.

WHAT YOU GET
0-100 SEO & GEO score - an instant health check of the current page, so you know at a glance what needs work.
Essential on-page checkpoints - title, meta description, headings (H1-H6), canonical, robots/X-Robots-Tag, status code, viewport, declared language, word count, image alt coverage and more, organized across 8 clean tabs.
Keyword Placement - check whether your target keyword appears where it matters: title, meta description, H1, subheadings, URL, first paragraph, image alt text and more (12+ scored locations), with in-context highlighting.
Schema & Technical SEO - structured-data detection, hreflang validation with duplicate detection, redirect detection (whether the page reached its final URL via a redirect), and SEO-relevant response-header checks.
GEO / AI Overviews readiness - signals that help AI answer engines (such as Google's AI Overviews, ChatGPT and Perplexity) parse and cite your page, including /llms.txt detection and question-form heading checks.
HTML vs rendered DOM diff - see content that only appears after JavaScript runs, so you know what crawlers actually get versus what users see.

PRIVACY FIRST
No tracking, no analytics, no ads, no account required.
All analysis happens locally in your browser.
Network requests go only to the page you're analyzing - to read its HTML, response headers, favicon and /llms.txt. Nothing is sent to our servers.
Nothing is stored or retained after you close the popup.
