SEO, GEO, Accessibility & Security Features: What We Measure and Report

SEO-GEO combines traditional search engine optimization checks with Generative Engine Optimization (GEO), WCAG accessibility and a passive security audit — so you can improve visibility in search and AI systems, usability for everyone and basic hardening, all from one crawl.

Key takeaways

· 100+ checks across technical SEO, on-page, GEO, accessibility and security.
· Four scores — SEO (search engines), GEO (AI systems), WCAG (accessibility) and Security — in one report.
· Actionable list of issues with severity and recommendations.
· See methodology for how we calculate scores and how it works for the process.

SEO analysis features: what we check

Our SEO module evaluates everything that affects how search engines crawl, index, and rank your site.

Technical SEO

Indexability — robots.txt, meta robots, canonical tags, and redirects.
XML sitemap — presence, validity, and coverage.
Core Web Vitals — LCP, FID/INP, CLS where measurable.
Mobile-friendliness — viewport, tap targets, and mobile usability signals.
HTTPS and security — SSL and basic security headers.
Structured data — Schema.org markup validation and errors.

On-page and content

Title and meta description — length, uniqueness, and relevance.
Headings — H1 presence, hierarchy, and keyword usage.
Content quality — length, readability, and topical signals.
Internal linking — anchor text and link structure.

GEO (AI visibility) features

GEO focuses on factors that help AI systems like ChatGPT, Perplexity, Claude, and Google AI Overviews understand and cite your content.

AI readability — clear structure, definitions, and answer-style content.
E-E-A-T signals — experience, expertise, authoritativeness, trust (author, dates, sources).
Citation-friendly markup — Schema.org, clear facts, and source attribution.
Content clarity — concise answers, lists, and scannable format.

For details on how we weight and score these, see our methodology.

Accessibility (WCAG) features

From v2.0, every audit includes a WCAG-oriented accessibility branch aligned with the POUR principles (Perceivable, Operable, Understandable, Robust), based on static HTML analysis.

Perceivable — alt text, landmarks and page structure for screen readers.
Operable — skip links, link purpose and keyboard-friendly markup.
Understandable — form labels, language attribute and heading hierarchy.
Robust — valid ARIA, unique IDs and table headers.

Security features (new in v2.1)

The Security branch is a passive, static audit of response headers, the returned HTML and a few read-only probes. It never injects payloads or runs active penetration testing, so it is safe to run on any site you own or are auditing. The score is weighted Transport 30% + Headers 30% + Content 25% + Exposure 15%.

Transport — HTTPS, HTTP→HTTPS redirect, HSTS and mixed-content references.
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, risky inline scripts and known outdated JS libraries.
Exposure — cookie flags (Secure, HttpOnly, SameSite), server/framework version disclosure, security.txt and accidentally exposed files.

A good passive score is not a guarantee of security — see the security methodology for scope and limitations.

Scoring and report output

Each audit produces four scores and a detailed issue list, plus a combined score (the average of the four pillars). Severity levels help you prioritize: fix critical items first, then warnings, then informational suggestions.

Output	What it means
SEO score	A–F grade and 0–100; technical + on-page + content signals for search engines.
GEO score	A–F grade and 0–100; structure, E-E-A-T, and citation readiness for AI.
WCAG score	A–F grade and 0–100; accessibility across Perceivable, Operable, Understandable, Robust.
Security score	A–F grade and 0–100; passive transport, headers, content and exposure hardening.
Critical	Issues that strongly affect score and should be fixed first.
Warning	Important but less severe; fix after critical items.
Info	Suggestions and best practices; lower impact on score.
