# GApex — GEO Readiness Checker

> GApex is the GEO (Generative Engine Optimization) readiness checker for the AI search era. It audits a website across 25 categories and 100+ signals to measure how visible, quotable, and citable the site is to ChatGPT, Perplexity, Google AI Overviews, Claude, and Copilot.

GApex helps product teams, marketers, and agencies understand whether their website is discoverable and correctly represented by large language models. A single audit returns an AI Visibility Score (0–100), a category breakdown, and actionable fix recommendations.

## What GApex checks

- **Crawl access**: robots.txt, llms.txt, sitemap.xml, .well-known manifests, and explicit allow/deny rules for AI bots (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and 12 more).
- **Content extractability**: server-side rendering vs. client-side JS, semantic HTML, heading structure, readable text ratio.
- **Meta & structured data**: title, description, Open Graph, Twitter card, JSON-LD Organization/FAQ/HowTo, canonical.
- **Authority signals**: HTTPS, security headers, author attribution, sameAs profile links, cross-platform presence.
- **Answer-format readiness**: FAQ blocks, step-by-step instructions, comparison tables, TL;DR summaries, quotable statistics — content shapes AI models prefer to cite.
