GEO stands for Generative Engine Optimization. It is the work of getting your business mentioned, cited or recommended in answers from AI tools like ChatGPT, Gemini, Claude, Perplexity and Google’s AI Overviews and AI Mode.
It has nothing to do with geography. That confusion is common because “geo” already meant location in marketing (“geo-targeting”). In AI search, it means generative engines.
Where the term came from
The term was formalized in a 2023 research paper, “GEO: Generative Engine Optimization,” by researchers from Princeton University and IIT Delhi, later published at KDD 2024 (the original GEO paper). They defined “generative engines” as search tools that pull from several sources and write one answer, and they tested what makes a source more likely to show up in that answer.
Their headline finding: adding citations, quotations and statistics to content increased visibility in AI answers by up to 40% on their benchmark of 10,000 queries. Results varied by topic.
GEO vs. SEO: what is actually different
| SEO | GEO | |
|---|---|---|
| Goal | Rank in a list of links | Be named or cited in a written answer |
| Where | Google and Bing results, map pack | ChatGPT, Gemini, Claude, Perplexity, AI Overviews, AI Mode |
| Success looks like | Position, clicks, calls | Mentions, citations, calls from people who “asked AI” |
| Typical query | “emergency plumber phoenix” | “Who’s a reliable plumber in Phoenix that can come tonight for a burst pipe?” |
The honest version: GEO is mostly built on top of SEO, not instead of it. AI tools that browse the web still find pages through search indexes. If Google can’t find and trust your site, ChatGPT usually can’t either.
Why it matters for a local business
BrightLocal‘s 2026 survey found 45% of U.S. consumers asked an AI tool for a local business recommendation in the past year, up from 6% the year before. ChatGPT was the most used tool for it.
And clicks from regular search are shrinking when an AI answer is on the page: Pew found 8% click a result with an AI summary versus 15% without (Pew Research Center). If the answer names your competitor, many people never scroll to your listing.
What GEO work looks like in practice
1. Make your facts easy to quote
AI answers lift specific, plain statements. “We’re a family-owned HVAC company” gives it nothing. Say you run an HVAC company. A line like “Licensed in Arizona (with your ROC license number), same-day AC repair in Chandler, Gilbert and Mesa, $89 diagnostic fee” gives it four facts to repeat. (Hypothetical example; use your real details.)
2. Show up where AI tools look
AI assistants cross-check sources. For a law firm that means Avvo, Justia and the state bar directory, not just Google. For a dentist, Healthgrades and Zocdoc. BrightLocal found ChatGPT can’t see inside Google’s reviews, so reviews on other platforms carry extra weight.
3. Structure the page
Clear headings, FAQ sections that answer real questions, and schema markup (LocalBusiness, Service, FAQPage) make it easier for any system to understand what you do and where.
4. Keep NAP consistent
Same name, address and phone everywhere. An old suite number on Yelp is the kind of conflict that makes an AI hedge or skip you.
5. Track mentions
Ask the AI tools the questions your customers ask, every month, and log who gets named. It’s manual, but it’s the most honest measure we’ve found.
