SEO for AI search resultsPrinceton term, 2023the market debates: GEO versus AEOKPI - citation share
GEO (Generative Engine Optimization) - promotion inside AI answers: the work of getting ChatGPT, Perplexity and AI Overviews to cite your site and recommend your brand. Classic SEO fights for a place in the list of links; GEO fights for a place in the answer itself. The discipline is young: the term is three years old, and the market is still arguing about what to call it.

SEO: a spot in the list GEO: getting into the answer
# a search engine returned links - a generative engine returns an answer; GEO optimizes getting into the answer itself▌1. What it does and what it is not
What it gives you
- +visibility where demand has moved: every second Runet user uses AI tools (51%)
- +a measurable KPI: the share of brand citations in answers, not search-ranking position
- +works on top of SEO: clean structure, direct answers, facts with dates and sources
- +
What it is not
- −not a replacement for SEO: Google calls optimization for AI search "still SEO" (07.2026)
- −not one established term: the same work is sold as AEO, LLMO, and AI SEO
- −not a set of tricks: Google publicly advises against "hacks" such as llms.txt (01.2026)
- −not a guarantee: citation mechanics are closed, so measurement and iteration are what work
What we call it
We call it: GEO. Also known as: AEO, AI SEO, AI marketing, generative optimization. Didn't stick: AIO, AI SEO.

2. How it works - no mysticism
How a page gets into a neural network answer - four stages:
01IndexingAI search bots (GPTBot, PerplexityBot) read your site. A site closed to bots never makes it into the answers
02Extractionthe engine looks for fragments that answer the question. A direct answer in the first paragraph and facts with numbers are extracted; fluff - not
03Synthesisthe answer is assembled from several sources. Trust decides whom to cite: author, date, sources for figures
04Citationthe brand gets into the answer with a link or mention. This is the result of GEO; measured by the share of citations across a query pool
Families · Engines optimized for. The mechanics are shared, but each has its own entry point and audience:
| Type | What it's for | Today |
|---|---|---|
| AI Overviews (Google) | AI summary above classic search results | in 18-30% of queries; link clicks are falling |
| ChatGPT Search | search inside chat | 100+ million active users (April 2026) |
| Perplexity | answer engine with citations | the benchmark format of "answer + sources" |
| Runet neural answers | 88 million audience (summer 2025) | |
| Chatbots without search | answers from the model's own memory | the LLMO angle: getting into training data |
3. Three years from a Princeton paper to a profession
The term was born in academia, not marketing - a rare case for the SEO world. The timeline explains why there is still no standard.

GEO paper
Princeton, Georgia Tech, and coauthors publish "GEO: Generative Engine Optimization" (arXiv) - the discipline's only term with a birth date
2024.05
AI Overviews

Honestly: you do not need an agency at the start. The GEO foundation is the same work as honest SEO, and you can do it yourself.

GEO - the only term in the discipline with a birth date: 11/16/2023
The paper “GEO: Generative Engine Optimization” (Princeton, Georgia Tech et al., arXiv 2311.09735) was presented at ACM SIGKDD 2024. AEO has no clear author: attribution to Jason Barnard (2017) is his own marketing.

Google's position
Google's official guide (07/10/2026): optimization for AI search - “still SEO”
Google acknowledges the terms AEO and GEO, but collapses the discipline back into SEO. Danny Sullivan publicly discourages “hacks” such as llms.txt and chunking (01.2026).

5. Myths vs. measurable reality
The discipline is young, and there are more myths around it than practice. A breakdown of the most persistent ones:
"SEO is dead, now there is only GEO"
Google (07.2026): optimization for AI search - "still SEO." The foundation is shared; GEO adds the direct-answer format and a new KPI - citation share
"AIO is the discipline's main name"
AIO has three readings: all-in-one in hardware, AI Overviews in SEO circles, AI Optimization at some agencies. Industry advice: do not use it without clarification
"There is one standard term"
the market is genuinely split: Ahrefs and Semrush use GEO, HubSpot and Profound - AEO, job listings - "AEO/GEO" with a slash. Runet has chosen GEO
"These are tricks: llms.txt and special files"
Google publicly advises against hacks (01.2026). It cites what it ranks: useful structured content with provenance
"This does not work in Runet"
agencies sell GEO promotion - the industry is already here
6. GEO, AEO, AIO, LLMO, AI SEO - who is who
One job - different labels, and this is the discipline's main confusion. Term map as of August 2026:
| Term | What it is | Example |
|---|---|---|
| ·GEO | Generative Engine Optimization: getting into generative-engine answers | the Princeton term (2023); the choice of Ahrefs, Semrush, and Runet |
| ⊃AEO | Answer Engine Optimization: direct answers and snippets | the choice of HubSpot and Profound; it existed back in the voice-assistant era |
| ⊃⊃AIO | read three ways: all-in-one, AI Overviews, AI Optimization | Runet search results for "AIO" show all-in-one PCs and coolers |
| ⊃⊃⊃LLMO | LLM Optimization: getting into the model's own knowledge | a rare, developer-focused angle on the same work |
| ⊃⊃⊃⊃AI SEO | everyday label for the whole discipline |
7. Common questions and where to go next
▸What is GEO in simple terms?
Promotion in AI answers. Classic SEO fights for a spot in the list of links, GEO - for ChatGPT, Perplexity and AI Overviews to cite your site inside the answer itself. It stands for Generative Engine Optimization, a term from a Princeton paper (November 2023).
▸Which is correct: GEO, AEO, or AIO?
Our verdict (Aug 18, 2026): GEO. AEO is a live synonym (chosen by HubSpot and Profound), which we address alongside it. We do not use AIO: the abbreviation is read three ways - all-in-one, AI Overviews, AI Optimization - and does not work without an expansion.
▸Does GEO replace SEO?
No. Google states directly (July 2026): optimization for AI search - “still SEO.” The foundation is the same: structure, useful content, trust. GEO adds a direct-answer format, dates and sources for facts, openness to AI bots, and a new KPI - citation share instead of search ranking.
▸
▸How much does GEO promotion cost?
Agency pricing has not stabilized: the market is young, and GEO agency rankings on vc.ru appeared only in 2026. The foundation can be done for free by yourself: a direct answer in the first paragraph, figures with dates and sources, and a site open to AI bots. It is the same work as honest SEO.
▸How do I check whether AI cites me?
Ask ChatGPT and Perplexity about your niche the way a customer would, and see who the engines cite. For regular tracking there are AI visibility monitoring tools (Profound, Otterly, Peec) - they measure a brand's share of citations across a pool of queries.
