What every report measures
One scan runs six modules in parallel and combines them into the Nalyzed Score, with a separate GEO readiness score for AI search.
- Performance
- Mobile and desktop Lighthouse, Core Web Vitals (LCP, CLS, INP, TTFB), accessibility and page weight.
- SEO & GEO
- Titles, meta tags, canonical, structured data, sitemap, indexability, AI crawler access and llms.txt.
- Security
- TLS certificate trust and expiry, HTTPS redirect, security headers, SPF and DMARC.
- Technology
- 200+ fingerprints: CMS, frameworks, ecommerce, analytics, consent tools, CDN and hosting.
- Domain
- Registrar, domain age, name servers, server location and DNS records.
- Popularity
- Tranco rank and a clearly labeled, rank-based traffic estimate.

Frequently asked questions
- Is Nalyzed free?
- Yes. Analyses, reports, comparisons, badges and exports are free and need no account. A fair-use limit of a few new analyses per hour applies.
- How is the Nalyzed Score calculated?
- It is a weighted average of performance (30%), SEO (30%), security (25%) and best practices (15%). Categories that could not be measured are excluded rather than counted as zero. The methodology page lists every check.
- How often are reports updated?
- Anyone can request a new scan once a day. Verified site owners can enable free weekly monitoring with RSS and webhook alerts.
- What is GEO readiness?
- A separate 0–100 diagnostic of the technical signals AI search engines rely on: crawler access, snippet permissions, answerable content, attribution cues and discovery. It does not measure actual AI citations.
- Can I remove my site's report?
- Yes. Site owners can request removal and the report, badge and exports stop being served.
