Learn: AI Search Optimization, AEO, GEO & Content
AI SEO, LLM SEO, AEO and GEO mostly describe the same work with different words: making your site reachable, readable, structured and citable for AI assistants. This hub defines each term, links the guide for it, and points to the checks that measure it on your own site.

Terms, defined
Plain definitions for the vocabulary used across AI search. Each links to a longer guide.
- AI Search Optimization — also called AI SEO
- The practice of making a website reachable, readable and quotable by AI assistants and AI-powered search results, rather than optimising only for classic ranked link lists.
- Answer Engine Optimization (AEO) — also called AEO
- Structuring pages so an answer engine can extract one direct, correct answer — clear questions, immediate answers, unambiguous entities and supporting structured data.
- Generative Engine Optimization (GEO) — also called GEO
- Improving the odds that generative engines select, cite and recommend your site as a source, which depends on clarity, authority signals, citations and machine-readable structure.
- LLM Optimization — also called LLM SEO
- Preparing content specifically for how large language models ingest text: server-rendered content, plain language, defined entities and self-contained passages.
- Content structure for AI
- Heading hierarchy, semantic HTML, paragraph length and answerability — the formatting decisions that determine whether a model can lift a usable answer from your page.
- Structured data for AI — also called Schema markup
- JSON-LD schema that states explicitly what a page is about, who published it and what entities it describes, so engines do not have to guess.
- AI crawlers
- The user agents behind AI assistants — GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended — whose access your robots.txt and rendering decisions control.
- ChatGPT SEO
- The subset of AI search work aimed at how ChatGPT fetches, reads and reuses web content, including its browsing user agents.
- Perplexity SEO
- Optimising for citation-driven engines such as Perplexity, where sourcing, freshness and factual clarity decide whether you are linked in an answer.
