Definition
AI SEO is search engine optimization extended to AI-powered search: getting a brand mentioned and cited in the answers ChatGPT, Gemini, Perplexity and Google’s AI features write, not just ranked in a list of links. The term is used two ways. Most often it means optimizing for AI search. Sometimes it means using AI tools to do SEO work. This page covers the first meaning.
Also called: AISEO, AI search engine optimization, GEO, AEO, AISO, LLMO

At a glance
- AI SEO is the most familiar label for SEO teams moving into AI search.
- It builds on the same base as SEO: crawlability, clear structure, authority.
- The scoreboard changes from rank to mention and citation.
- It’s a near-synonym for GEO, AEO and AI search optimization.
What changes from regular SEO
The technical foundation stays the same. A page that a crawler can’t read fails in both. What changes is the unit that wins. In SEO, the page ranks. In AI search, a passage gets quoted. That rewards pages written in self-contained, clearly answered sections, with facts a model can lift without editing.
Measurement changes too. Rank tracking tells you where a page sits on Google. AI SEO needs prompt tracking: asking assistants your buyers’ questions and recording whether you’re named.
The two meanings of AI SEO
“AI SEO” also gets used for AI-assisted SEO: using AI to write briefs, cluster keywords or generate metadata. That’s a workflow change, not a new channel. If someone pitches you AI SEO, ask which one they mean.

How this term is used
AI SEO is popular because it needs no explanation. In Fractl’s study, reported by Search Engine Land, 60% of marketers recognized AI SEO, roughly level with AEO. The trade-off is ambiguity: the same phrase covers optimizing for AI and optimizing with AI.
The category is still new and these terms are used interchangeably across the industry. For a side-by-side of what each one means and who uses it, see AEO vs GEO vs AI SEO. All of them describe the organic branch of AI search marketing.
Frequently asked questions
-
Is AI SEO the same as GEO?
In practice, yes. GEO is the more specific term. AI SEO is the friendlier one for teams that think of this as part of SEO.
-
Do I need a separate AI SEO strategy?
You need separate measurement. The content and technical work mostly overlaps with good SEO. Prompt tracking is the piece most SEO programs are missing.
