Web Traffic
Analyzer

It performs 12+ categories of analysis in a single scan: technology detection (frameworks, CMS, analytics, CDN, server stack), full SEO audit (meta tags, Open Graph, headings, structured data), performance analysis (response time, compression, resource hints, lazy loading), security posture (HTTPS, HSTS, CSP, and 10+ security headers), DNS infrastructure (records, nameservers, email security with SPF/DMARC/BIMI), accessibility checks (ARIA, lang attribute, alt text), content analysis (word count, reading time, language detection, text-to-HTML ratio), link analysis (internal/external/nofollow), resource counting, and social presence detection.

Each category (SEO, Performance, Security, Accessibility) starts at 100 and points are deducted based on the severity of issues found. Critical issues deduct 15-20 points, high issues 12-15, warnings 5-8, and low issues 2-3. Bonus points are added for best practices like structured data and HSTS. The overall score is the average of all four categories.

The analyzer examines HTTP response headers, HTML source code, JavaScript references, CSS class patterns, and DNS records to fingerprint the technology stack. It can detect 100+ technologies across categories like frameworks (Next.js, React, Vue, Angular), CMS (WordPress, Shopify), analytics (GA4, GTM, Hotjar), CDN (Cloudflare, Fastly), servers (Nginx, Apache), and more. Each detection includes a confidence score.

Unlike SimilarWeb (traffic estimation) or Ahrefs (backlink focus), this tool performs a real-time deep scan of the actual website. It combines technology detection (like BuiltWith/Wappalyzer), SEO auditing (like Ahrefs Site Audit), security scanning, performance analysis, and DNS inspection — all in one free tool. No API keys, subscriptions, or browser extensions needed.

No — the analyzer makes a single GET request to the page (just like a normal browser visit) plus lightweight DNS queries. It does not perform penetration testing, brute-force attacks, or any invasive actions. The impact is equivalent to one page view.
