Question 1

What is Generative Engine Optimization (GEO)?

Accepted Answer

GEO is the practice of making a website discoverable and quotable by AI answer engines like ChatGPT, Perplexity, Claude, and Google AI Overviews. Unlike traditional SEO, GEO optimizes for both AI crawl access (explicit robots.txt rules for GPTBot, ClaudeBot, PerplexityBot) and for content formats that LLMs prefer to cite (definitions, lists, tables, FAQs, quotable statistics).

Question 2

How does GApex audit a website?

Accepted Answer

GApex runs 100+ discrete checks across 25 categories: HTTPS, robots.txt, llms.txt, sitemap.xml, .well-known manifests, platform registration, meta tags, Open Graph, JSON-LD structured data, semantic HTML, heading structure, content extractability, content quality, technical crawlability, security headers, authority signals, brand entity knowledge graphs, trust & safety signals, cross-platform presence, and AI answer-format readiness. The result is a 0–100 AI Visibility Score with a letter grade, a category-by-category breakdown, and an actionable list of fixes.

Question 3

Why is server-side content important for AI crawlers?

Accepted Answer

Most AI crawlers — including GPTBot, ClaudeBot, and PerplexityBot — do not execute JavaScript. A pure client-side-rendered SPA appears almost empty to them, which means LLMs never see the content and cannot cite it. Adding server-side rendering, static-site generation, or a content-rich index.html fixes this.

Question 4

Which AI bots should I allow in robots.txt?

Accepted Answer

At minimum: GPTBot and ChatGPT-User (OpenAI), OAI-SearchBot (ChatGPT search), Google-Extended (Gemini + AI Overviews), ClaudeBot and anthropic-ai (Claude), PerplexityBot and Perplexity-User (Perplexity), Applebot-Extended (Apple Intelligence), CCBot (Common Crawl, used as LLM training source), and Meta-ExternalAgent. Explicit allow rules are a stronger signal than relying on wildcard fallback.
