Mega SEO Analyzer

Paste one URL, get back what Ahrefs, SEMrush, and Sitebulb charge $100-$500 a month to tell you: authority, hygiene, AEO, performance, trust, compliance, plus real-user CrUX field data, competitor gap matrix, site-wide sample crawl, and a 90-day roadmap. No signup, no paywall, no tracking pixel. Pair it with Mega Analyzer for on-page SEO depth and Mega Security Analyzer for the security layer.

Analyze — single URL, site-wide sample, or competitor compare

Full URL (protocol + host + path)

Paste rendered HTML instead (for SPA shells like Squarespace / Wix / Popmenu / Pixieset, or sites that bot-block the proxy)

When the static fetch can't see your real content, paste the post-hydration HTML here. The eight-dim Mega SEO scorecard runs against the pasted DOM. Sibling resources (robots.txt, sitemap.xml, llms.txt, all 26 well-known files) and CrUX field data are still fetched from the URL above if provided. Beginner walkthrough.

Fetch real-user CrUX field data via PageSpeed Insights API (LCP, INP, CLS, FCP, TTFB) Save score to localStorage history + show week-over-week trend
