What is GEO and AEO?

GEO (Generative Engine Optimization) is making your site easy for AI models to find, understand and quote. AEO (Answer Engine Optimization) is shaping your content so it becomes the answer an AI gives. Together they are the new layer on top of SEO: not just ranking in Google, but being the source an AI recommends.

This matters now because search is shifting. People ask ChatGPT, Perplexity and Google AI Overviews a full question and get a single answer, often without clicking any site. If the AI does not know you exist, you are invisible in that conversation.

How AI decides what to recommend

Three things decide whether an AI can use your site:

  1. Access: AI crawlers like GPTBot, ClaudeBot, PerplexityBot and Google-Extended must be allowed in your robots.txt. Block them and you are invisible to that model.
  2. Readability: most AI crawlers do not run JavaScript. If your content only appears after JS loads, they see an empty page. Server-rendered or static HTML wins.
  3. Understanding: structured data (Schema.org), clear semantic HTML, and citable formatting (lists, tables, FAQs) let the model extract a confident, quotable answer.

The checks that make you AI-visible

SignalWhy it matters for AI
AI crawler access (robots.txt)If GPTBot or ClaudeBot are blocked, that model can never cite you.
Content without JavaScriptAI crawlers rarely run JS; core text must be in the HTML.
Structured data (Schema.org)Lets AI establish who you are and what you offer with certainty.
llms.txtA short markdown map pointing AI to your most important pages.
FAQ with FAQPage schemaAI quotes clean question-and-answer pairs almost verbatim.
Semantic HTMLTags like main, article and section help AI read your structure.

How to become citable by AI

These are exactly the signals eighty checks, and the report gives you each fix in plain language.
