Audit pages the way modern search actually works. Live HTML. Real quality themes.
Google’s 2026 cores keep rewarding original, first-party, trustworthy pages — and pressuring thin or scaled commodity content. This free SEO checker live-fetches a public URL and scores technical indexability, on-page clarity, people-first heuristics, E-E-A-T cues, structured data, AI Overview extractability, and performance proxies (scripts/CSS/lazy-load) — then ranks fixes by impact.

- 8 score pillars: technical, on-page, people-first, trust, social, schema, AEO, UX proxies
- Update coverage notes for March/May 2026 cores + spam/AIO themes

Same email + consent gate as other free tools — unlock once, use the full club.

Tips for better seo checker results
HTML-only has limits
This tool cannot measure Core Web Vitals, backlinks, or Search Console queries — pair it with CrUX/PageSpeed and GSC.
JS-heavy apps under-report
If critical copy only appears after client render, crawlers (and this audit) may see thin HTML.
Fix indexability first
noindex, soft 404s, and HTTPS issues beat perfect meta descriptions every time.
Need SEO that compounds — not one-off audits?
LoudScale builds technical foundations, content systems, and AI search visibility so pages earn traffic and citations over time.

It checks durable on-page and quality signals aligned with modern SEO and AI visibility practice (indexability, helpful content/E-E-A-T cues, structured data, answerability). It does not reverse-engineer a secret ranking formula or pull live SERP rankings.
No for the core audit. An optional AI priority roadmap uses your own OpenAI-compatible key in the browser (BYOK), same as other AI tools in the suite.
No. It is a fast single-URL on-page auditor for marketers and founders — not a full crawl suite or link index.
