One-click on-page SEO checker: score, headings, links, Google & social previews, structured data and more. Free & private. Check any web page's on-page SEO in one click - no signup, no account, nothing leaves your browser. Click the AuditSEO icon on any page and instantly see: • A 0–100 on-page SEO score with clear pass / warning / issue breakdown • Title & meta description length measured in real pixels (how Google actually truncates) • Full heading outline (H1–H6) with skipped-level warnings • Internal / external / nofollow link counts • A live Google search-result preview and social-card (Open Graph) preview • Structured data (JSON-LD) detection, canonical, indexability, mixed content, image alt text, viewport, HTTPS and more • A one-click "Copy report" button Perfect for marketers, developers, bloggers and agencies doing quick on-page checks or spot-audits. Privacy: the extension analyzes only the page you're on, only when you click the icon. It uses just the "activeTab" and "scripting" permissions, requires no host permissions, and **collects no data** - nothing is sent to any server. Want the full picture? Run a complete audit at auditseo.app — or set up free monitoring: we re-check your page automatically and email you the moment its SEO changes (score drop, lost meta tag, accidental noindex, broken structured data). Pro monitoring covers up to 50 pages with daily checks and full change history.
