Website Doctor — Free Website Health Checker & Deep SEO Audit
Run an in-depth, authentic forensic diagnostic of your website's Technical SEO, Core Web Vitals, TLS Security, WCAG 2.1 AA Accessibility, and AI Search Readiness. Real-time streaming analysis with prioritized, developer-ready fixes.
The 9 Pillars of Modern Website Intelligence & Technical Health
Achieving high visibility in modern Google search and AI answer engines requires more than basic keyword insertion. Search algorithms evaluate page experience, security hygiene, accessibility, and crawl efficiency. Website Doctor investigates each critical dimension:
1. Technical SEO & Indexation
Verifies canonical tags, robots.txt directives, XML sitemap presence, HTTP response codes, and clean redirect chains to guarantee search engines crawl without friction.
2. Core Web Vitals & Latency
Measures Time-to-First-Byte (TTFB), First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS) against Google thresholds.
3. TLS Security & HTTP Headers
Inspects certificate expiration, cipher strength, Strict-Transport-Security (HSTS), X-Content-Type-Options, and Content-Security-Policy to protect against attacks.
4. WCAG 2.1 AA Accessibility
Audits missing image alt text, form label bindings, landmark elements (<main>, <nav>), viewport zoom restrictions, and heading hierarchy order.
5. Mobile Optimization
Validates responsive viewport meta configuration, touch target usability, and mobile rendering readiness for Google Mobile-First Indexing.
6. Content Depth & Quality
Evaluates word count density, text-to-code ratio, heading distribution (H1, H2, H3), and semantic readability to prevent thin-content penalties.
7. JSON-LD Structured Data
Scans for valid schema.org types (Organization, WebSite, Article, FAQPage) to qualify your pages for rich search snippets and Knowledge Graph inclusion.
8. AI Search & GEO Readiness
Checks robots.txt permission for ChatGPT (GPTBot), Claude (ClaudeBot), and Perplexity (PerplexityBot), author entity clarity, and citation discoverability.
9. Technology Fingerprinting
Detects underlying CMSs (WordPress, Shopify), modern frameworks (Next.js, React, Vue), web servers, CDNs (Cloudflare, Fastly), and analytics tags.
Frequently Asked Questions
What is Website Doctor and how does it evaluate a website?▼
Website Doctor is an authentic, multi-stage website health and technical audit platform. It runs real socket-level DNS queries, checks TLS certificate integrity, downloads and parses HTML DOM elements, evaluates Core Web Vitals performance, inspects WCAG 2.1 AA accessibility heuristics, checks JSON-LD schemas, and evaluates AI search crawler readiness without simulated scores or artificial delays.
How does this tool differ from basic online SEO checkers?▼
Most online checkers only inspect basic title tags and meta descriptions in 1–2 seconds. Website Doctor performs a full forensic investigation across 9 architectural categories, including HSTS and CSP defensive headers, time-to-first-byte (TTFB), robots.txt AI bot directives (GPTBot, ClaudeBot), image alt ratio, viewport zoom restrictions, and heading hierarchy.
Is this audit 100% free with no login required?▼
Yes. TechnoFreaks provides this tool as a completely free public service for software engineers, SEO professionals, founders, and site owners. You receive immediate real-time results, downloadable reports, and actionable fixes with zero paywalls.
What is AI Search Readiness (GEO) and why does it matter?▼
Generative Engine Optimization (GEO) analyzes whether your website content is discoverable, readable, and citeable by generative AI engines like ChatGPT Search, Perplexity, and Claude. Website Doctor verifies that your robots.txt does not inadvertently block AI search crawlers, checks entity schema markup, and validates semantic headings.
Can I share or export my Website Doctor report?▼
Yes. Every audit generates a unique shareable public link (e.g., https://technofreaks.online/report/abc123) that you can send to colleagues or clients. You can also print a publication-grade PDF report or export all findings as JSON or CSV files.
