AI SEO is the umbrella term for getting your brand found and cited across AI search (ChatGPT, Gemini, Google AI Overviews, Perplexity, Copilot). It encompasses AEO, GEO and LLMSEO, which are facets of the same job, not separate disciplines. The core moves: be crawlable for AI bots, write answer-first extractable content, win the two grounding indexes (Bing and Google), build a consistent entity, and measure grounding instead of clicks. This is the master one-page reference.
The acronyms multiply faster than the tactics. AEO, GEO, LLMSEO, AImention, AAO. They mostly describe the same work. This cheatsheet untangles the terms, then gives you the one checklist that covers all of them, with links to the deep-dive cheatsheet for each piece.
The AI search acronym map
What each term means, and how it relates to the others. Spoiler: they overlap heavily.
| Term | Stands for | What it targets | How it relates |
|---|---|---|---|
| SEO | Search Engine Optimisation | Ranking in search results | The foundation everything else builds on |
| AI SEO | AI Search Optimisation | Visibility across all AI search surfaces | The umbrella term (this page) |
| AEO | Answer Engine Optimisation | Being cited in AI-generated answers | The extraction and citation layer of AI SEO |
| GEO | Generative Engine Optimisation | Visibility in generative AI outputs | Used interchangeably with AEO. Same goal |
| LLMO / LLMSEO | LLM Optimisation / LLM SEO | Being represented in LLM training and retrieval | The model-knowledge layer |
The honest take: these are not five disciplines. They are facets of one job, be the source AI trusts and cites. Pick a term, stop arguing about it, and do the work below. See why AEO is not separate from SEO.

How AI SEO is measured
Stop reporting AI SEO as referral clicks (they are tiny and lagging). Measure grounding from your server logs: AI Crawler hits mean a page is being ingested, AI Assistant hits mean it is being cited live. The flip from crawler-dominant to assistant-dominant is the indexed-to-cited conversion. Track it per URL plus your Bing AI citation share.

Frequently asked questions
What is AI SEO?
AI SEO is optimising your brand and content to be found and cited across AI search surfaces (ChatGPT, Gemini, Google AI Overviews, Perplexity, Copilot). It is the umbrella that covers AEO, GEO and LLMSEO, which are facets of the same goal: being the source AI trusts and cites.
What is the difference between AEO, GEO and LLMSEO?
Very little in practice. AEO (answer engine optimisation) and GEO (generative engine optimisation) are used interchangeably for being cited in AI answers. LLMSEO or LLMO leans toward the model-knowledge layer. All three are facets of AI SEO. Do not let the acronyms distract you from the work.
Is AI SEO replacing traditional SEO?
No. AI SEO is the part of SEO that the new AI entry points make explicit. The same content quality wins both. The payoff just shifts from clicks to citations and brand presence in AI answers.
What is the single most important AI SEO move?
A consistent, machine-readable entity plus answer-first extractable content. AI assembles answers from clear, repeated facts about who you are and what you claim. Make those facts trivial to find and verify everywhere a machine looks.
How do I measure AI SEO?
Measure grounding, not clicks. Track the AI Crawler to AI Assistant ratio per URL in your server logs (the indexed-to-cited signal) and your Bing AI citation share. AI referral traffic is real but tiny, so it lags by weeks.
