What is generative engine optimization (GEO)?
Generative engine optimization (GEO) is the practice of shaping content, listings and brand mentions so AI engines cite or name a source inside a generated answer. A 2023 paper by Aggarwal et al., presented at KDD 2024, named GEO and measured visibility gains of up to 40% in AI answers. Compare GEO with SEO and AEO in the table below, then follow 5 GEO steps for Kansas City businesses.
| Attribute | SEO | AEO | GEO |
|---|---|---|---|
| Target surface | Ranked results and the map pack | Featured snippets, voice assistants, answer boxes | AI answers in ChatGPT, Perplexity, Gemini, Google AI Overviews and AI Mode |
| Unit of success | Position and click | One extracted answer | A mention or linked citation inside generated text |
| Main on-page tactic | Relevance, internal links, technical health | Question headings and ~40-word answers | Statistics, quotations and named sources a model can quote |
| Main off-page tactic | Backlinks | Entity consistency | Third-party mentions, listings and reviews |
What is generative engine optimization?
Generative engine optimization (GEO) is the practice of making content, business listings and third-party mentions easy for generative AI engines to retrieve, quote and cite. Its goal is a named mention or linked citation inside answers from ChatGPT, Perplexity, Gemini and Google AI Overviews.
A generative engine is an AI system that answers a prompt by running one or more web searches, reading the sources it retrieves, and writing one response from them, instead of returning a list of links. A large language model is the software that writes that response. A citation is the link or named source an engine attaches to a fact it used. Kansas City SEO Pros sells GEO and AEO services as part of local SEO, building the crawlable pages and sourced facts these engines cite.
How does generative engine optimization work?
GEO works on the retrieval step behind every AI answer. The engine runs web searches, reads the top sources, then writes one answer from them. GEO makes a page rank in those searches and gives it quotable facts, statistics and named sources.
Google names this process query fan-out: the engine runs multiple related searches across subtopics of one prompt before it writes an answer.

What does the generative engine optimization research paper say?
The GEO paper by Aggarwal et al., presented at KDD 2024, tested 9 content methods on 10,000 queries. Quotation addition, statistics addition and cited sources raised visibility in AI answers by up to 40%; keyword stuffing produced little or no gain.
Research card: "GEO: Generative Engine Optimization" — Pranjal Aggarwal, Vishvak Murahari, Tanmay Rajpurohit, Ashwin Kalyan, Karthik Narasimhan, Ameet Deshpande · arXiv 2311.09735 (first version 16 November 2023) · Proceedings of the 30th ACM SIGKDD Conference (KDD 2024), pp. 5–16 · DOI 10.1145/3637528.3671900. The paper built GEO-bench, a set of 10,000 queries split 8,000 for training, 1,000 for validation and 1,000 for testing, each carrying the top 5 search results. On Perplexity.ai, the same methods produced a 22% gain from quotation addition and a 37% gain from statistics addition. Cite Sources raised the visibility of the 5th-ranked site by 115.1% and lowered the 1st-ranked site's visibility by 30.3%.
| Method | What it changes | Reported effect |
|---|---|---|
| Quotation Addition | Adds quotes from credible sources | 41% (position-adjusted word count) |
| Statistics Addition | Replaces claims with numbers | 30–40% |
| Cite Sources | Adds named sources | 30–40% |
| Fluency Optimization | Improves readability | Reported gain, smaller |
| Easy-to-Understand | Simplifies language | Reported gain, smaller |
| Authoritative | Adds persuasive tone | Small |
| Technical Terms | Adds domain terms | Small |
| Unique Words | Adds rare words | Small |
| Keyword Stuffing | Repeats query terms | Little or no gain, below baseline in places |
What is the difference between GEO, SEO and AEO?
SEO ranks a page in a list of search results. AEO formats a page so an engine extracts one direct answer from it. GEO earns a mention or citation inside an AI-written answer. All 3 rely on indexable pages, clear entities and trusted sources.
Page-level answer formatting is its own practice: read answer engine optimization for local businesses for the question-heading and 40-word-answer rules AEO adds on top of this comparison.

Is GEO replacing SEO?
No. Google states that AI Overviews and AI Mode have no additional requirements beyond standard SEO: a page must be indexed and eligible to show a snippet. GEO adds citation-focused tactics on top of SEO, and the SEO foundation stays mandatory.
Google states: “There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.” (Google, “AI features and your website”, developers.google.com/search/docs/appearance/ai-features). What stays the same: crawlable, indexable pages; accurate business listings; recent reviews; links and mentions from trusted sites; clear entity data through Organization and LocalBusiness markup.
Which is better, GEO or traditional SEO, for local businesses?
Traditional local SEO delivers more reach today: Google's 3-pack showed 35.9% of local business locations, while ChatGPT recommended 1.2% in 2026. GEO adds the AI channel that 45% of consumers used to find local businesses in 2026, so both belong in one plan.

How does a local business do generative engine optimization?
A local business does GEO in 5 steps: allow AI crawlers in robots.txt, match its listings on Google, Bing and Apple, collect recent reviews, earn mentions on local websites, and add sourced statistics and quotes to service pages.
ChatGPT reads a narrower set of sources than Google; the guide on how ChatGPT picks local businesses covers exactly which ones.
- Allow AI crawlers
- Match your listings
- Collect recent reviews
- Earn local mentions
- Add quotable facts
How do you measure generative engine optimization?
GEO is measured with a fixed prompt set re-run every month in each AI engine. The 4 metrics are the share of answers naming the business, its position in each answer, the linked citations it earns and the third-party sources the engines cite.
- Answer share
- Answer position
- Linked citations
- Cited sources
