What the audit checks
39 individual checks across 15 modules — every one runs live against your real domain. No cached data, no estimates, no marketing fluff.
Response time, page weight, render-blocking scripts, DOM size, compression, AI bot policy in robots.txt, llms.txt presence, sitemap discovery.
Heading structure (H1–H3), word count, internal vs external links, image alt coverage, modern formats (WebP, AVIF), FAQ section detection.
JSON-LD parsing, Organization, LocalBusiness, Product, FAQPage, BreadcrumbList, WebSite, Review and Offer coverage scoring.
Flesch reading ease, average grade level, contact-signal detection, content depth, and language declaration.
WCAG 2.1 AA checks: alt text, form labels, ARIA landmarks, skip-nav, heading hierarchy, link text, language attribute.
Live Mozilla Observatory scan: CSP, HSTS, X-Frame, CORS, COOP, SRI, and grade A+ to F with deduction explanations.
Evaluates structure, authority, and discoverability signals that help automated systems understand the website.

IPv4, IPv6, nameservers, MX records, TXT count, email security (SPF, DMARC, DKIM), CDN identification, server location.
SERP snippet preview, Twitter and LinkedIn card rendering, Open Graph completeness, social profile detection, hreflang scan.
Real Google CrUX field data: LCP, INP, CLS — Core Web Vitals from actual Chrome users, not synthetic Lighthouse runs.
Why AI visibility matters
Search is splitting in two. Half your prospective customers still type into Google and click a blue link. The other half ask ChatGPT, Perplexity, Claude, or Gemini and read a generated answer — and AI answers only mention you if your site sends the right signals.
Traditional SEO targets ranking. GEO — Generative Engine Optimization — targets being quoted. The two share some signals (schema, page authority, content quality), but GEO also depends on entity grounding (Wikipedia, Wikidata), structured Q&A, specific facts, and whether AI crawlers can actually access your content.
The audit brings these signals into one clear view, showing what works, what is missing, and which improvements offer the highest return for the effort.
