Free Website Scanner — SEO, GEO, WCAG & Security — No Sign-Up Required

SEO-GEO is a free website scanner that checks your site for search engine optimization (SEO), generative engine optimization (GEO — AI visibility for ChatGPT, Perplexity, Claude and Google AI Overviews), WCAG accessibility basics and website security (a passive audit of HTTPS, security headers and information exposure). We are expanding toward a general-purpose scanner that surfaces anything worth improving on your pages.

What is GEO — Generative Engine Optimization?

GEO (Generative Engine Optimization) is the practice of making your website readable and citable by AI language models and AI-powered search engines. Unlike geographic (local) SEO, GEO focuses on structure, factual density, schema markup, llms.txt configuration, and named entity clarity so that large language models include your content in their answers. AI-driven search sessions grew 527% year-over-year in the first half of 2025. GEO is no longer optional.

What Does Our Scan Cover?

SEO Analysis

• Technical SEO: crawlability, indexability, canonical tags, robots.txt, sitemap.xml
• On-page SEO: title tags, meta descriptions, heading structure, keyword usage
• Core Web Vitals: Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint
• Content quality: E-E-A-T signals, readability score, internal linking structure
• Site structure: URL hygiene, breadcrumbs, orphan-page detection, structured data coverage
• Mobile-friendliness and page speed assessment

GEO Analysis

• llms.txt presence, format validity, and content quality
• Schema markup (JSON-LD): Organization, Article, FAQPage, Product, SoftwareApplication
• AI bot crawler permissions: GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot
• Content structure for AI citation: facts in first 30% of text, header hierarchy, list usage
• Named entity density: people, organizations, places, dates clearly identified
• Factual density and citation potential for AI answer engines
• Structured data completeness for rich results in AI search interfaces

Accessibility (WCAG) Analysis

• Landmarks, skip links and page structure for screen readers
• Form labels, button names and accessible names
• Heading hierarchy and unique page titles
• Alt text, table headers and basic ARIA usage
• Perceivable, operable, understandable and robust HTML checks

Security Analysis (passive)

• Transport: HTTPS, HTTP→HTTPS redirect, HSTS and mixed-content references
• Security headers: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and CORS
• Content: forms over HTTP, tabnabbing, iframe sandboxing, Subresource Integrity and risky inline scripts
• Exposure: cookie flags (Secure, HttpOnly, SameSite), server/framework version disclosure, security.txt and accidentally exposed files
• Passive and static only — no active penetration testing or payload injection

How It Works

1. Enter the URL of the website you want to scan in the form above.
2. Our crawler fetches and analyzes pages — checking HTML, headers, structured data, accessibility signals and AI-readiness.
3. Within minutes you receive scored reports with issues grouped by severity: critical, high, medium, and low priority.
4. Each issue comes with a clear explanation and an actionable fix you can implement immediately.
5. Optionally, generate a full PDF report to share with clients or your team.

Who Is This Tool For?

• SEO specialists and consultants who need a fast snapshot of SEO, GEO and accessibility on any website.
• Digital marketing agencies that want combined reports covering search, AI and accessibility.
• Web developers and CTOs checking technical health, accessibility, security hardening and AI-readiness before and after deployments.
• Content marketers and CMOs ensuring content works for search engines, AI assistants and all visitors.
• Business owners who want one place to see what to fix next on their site.

Why SEO, GEO, Accessibility and Security Together?

Search engines, AI assistants and real visitors all read the same HTML — but they care about different signals. A page optimized only for Google may still be invisible to ChatGPT, hard to use for people with disabilities, or missing basic security hardening. SEO-GEO combines SEO, GEO, WCAG and passive security checks into one scan with a prioritized fix list, so you know what to improve next. More check categories are on the roadmap.

Key Metrics and Scoring

Every audit produces separate SEO, GEO, WCAG and Security scores (0–100 and letter grades), plus category breakdowns so you can see exactly where to focus effort. The combined score is the average of the four pillars. Issues are weighted by impact: fixing a critical issue may improve your score significantly, while a low-priority issue contributes less.
