SEO checker and on-page SEO audit for any page -- including the pages a cloud crawler can never see. Enterprise SEO Auditor is a technical SEO audit tool that runs inside Chrome. Open any page, click the icon, and get a weighted SEO score with a prioritised list of what to fix: title and meta tags, headings, content depth, canonical and indexing directives, images, internal links, Open Graph and Twitter cards, structured data, hreflang, security headers, Core Web Vitals and more. WHY IT REACHES PAGES OTHER SEO TOOLS CANNOT Because the audit runs in your own browser, in your own session, it works where cloud crawlers stop: - http://localhost and any local dev server - staging sites behind basic auth, an IP allowlist or a VPN - pages behind a login: dashboards, member areas, checkout steps, gated content - pages with noindex or a blocking robots.txt, which crawlers refuse to fetch No site verification, no crawl budget, no waiting in a queue.
