Free on-page SEO audit + AI readiness (GEO) for any page: title, meta, H1, canonical, schema, noindex. Instant, no login.

See the technical SEO and the AI readiness (GEO) of any page in one click, without leaving the tab and without creating an account. Search is no longer only Google. ChatGPT, Perplexity and other AI assistants answer questions by reading pages. SEOWrench checks a page for classic SEO and for the signals that help those engines understand it. WHAT IT CHECKS • Title tag: presence and length • Meta description: presence and length • H1: presence and count (ideally exactly one) • Heading hierarchy: no skipped levels (an H1 followed directly by an H3, for example) • Canonical link • Indexability: noindex in the robots meta tag • Viewport (mobile) • Page language (html lang) • Open Graph: og:title and og:image, for link previews • Structured data (JSON-LD): the schema types found • Image alt text: how many images have none WHAT YOU GET • A 0–100 score with a letter grade, so you know where you stand at a glance • Issues ranked by severity, not a flat list • Every issue opens into why it matters and how to fix it, in plain language • "Show on page" outlines the H1 or the images without alt text right in the tab, and scrolls to them, so you find the problem instead of hunting for it • English and Portuguese, switchable in the popup PRIVACY, PLAINLY The analysis runs entirely in your browser. It reads the tab you are on, shows you the result, and discards it when you close the popup. No page data is uploaded or stored, and no account is needed. The extension asks for no host permissions: it only reads the active tab, and only when you click the icon. The only things it remembers are your language and whether you already answered the rating request. WHO IT IS FOR Developers checking a page before shipping. Agencies reviewing a client's page during a call. Content and marketing teams who need to know if a page is ready to publish. NEED THE WHOLE SITE? This extension analyzes the page you are on. To audit many pages at once, with the AI readiness of the whole site, there is seowrench.com. The free plan audits up to 5 pages at a time, 3 times a day, with no credit card.
