What Is Generative Engine Optimization (GEO)? A Plain-English Answer for Business Owners
When a customer asks ChatGPT or Google's AI "who can fix my water heater near me", the answer names two to five businesses, and the customer often calls one of them without ever visiting a website. Generative engine optimization is the work of being one of those names. This guide explains what it is, why AI picks some businesses over others, what you can do yourself, what it costs, and what to ask before hiring anyone for it.
When I tell a business owner I do generative engine optimization, I usually get a polite nod and the same follow-up question: so, like SEO? Almost nobody outside marketing knows what GEO is, and inside marketing half the people selling it describe it differently.
Meanwhile your customers already use it. They ask ChatGPT "who installs tankless water heaters near me," they read the Google AI Overview at the top of the results, they ask Perplexity to compare three companies. An answer comes back with a few business names in it, and either yours is one of them or it isn't.
Generative engine optimization (GEO) is the work of getting your business named, recommended and linked inside the answers that AI assistants write: ChatGPT, Google AI Overviews and AI Mode, Gemini, Perplexity, Microsoft Copilot. That's the whole definition. The rest of this article is what that means in practice, how it differs from the SEO you may already pay for, and how to tell real GEO services from a rebranded blog package.
What does GEO stand for in marketing?
In marketing, GEO stands for generative engine optimization. "Generative engine" means any system that writes an answer instead of showing a list of links: ChatGPT, Gemini, Perplexity, Copilot, and the AI Overviews and AI Mode inside Google Search. "Optimization" means the same thing it means in SEO: making your business the one that system picks.
The term isn't vendor jargon invented last quarter. It comes from a research paper, GEO: Generative Engine Optimization (Aggarwal, Murahari, Rajpurohit, Kalyan, Narasimhan and Deshpande), first published in November 2023 and presented at KDD 2024, a major computer science conference. The authors tested how changes to a page affect whether an AI engine uses it in an answer, and reported that the methods "can boost visibility by up to 40% in generative engine responses," and, just as important, that what works varies from one industry to another. That second finding is the one most GEO sellers leave out.
One warning if you go searching: the bare word "geo" mostly means geography, and "geo marketing" often means location-based ad targeting. When you're comparing providers, look for the phrase spelled out (generative engine optimization) so you know you're reading about the same thing.
What is GEO in SEO terms, and how is it different?
If you already understand SEO, here is the shortest way to see the difference:
| Classic SEO | Generative engine optimization (GEO) | |
|---|---|---|
| Where your customer looks | A list of ten blue links | One written answer |
| What you're competing for | A position in the list | A mention inside the sentence |
| How many winners | Ten per page, plus ads and the map | Usually two to five names |
| What the customer does next | Clicks and compares | Often calls the name they were given, without visiting any site |
| What decides it | Relevance, links, technical health | All of that, plus whether the AI can find a clean, trustworthy fact about you to repeat |
SEO gets you ranked, while GEO gets you recommended. A business ranked seventh on Google still gets some clicks. A business left out of the ChatGPT answer gets nothing from that conversation: the customer never knew it existed.
That doesn't make SEO obsolete, and anyone telling you to drop it is selling something. AI assistants find most of what they repeat by searching the web themselves. A page that Google never indexed is a page ChatGPT will rarely find. I break down where the three labels (GEO, AEO and SEO) genuinely differ and where they're the same work in GEO vs AEO vs SEO.
Why does ChatGPT recommend some businesses and not others?
This is the question owners actually care about, so here's the mechanism without the jargon.
When someone asks an AI assistant a question that needs current or local information, the assistant runs searches, opens a handful of pages, pulls facts out of them, and writes an answer. It names the businesses whose pages gave it something usable. Three things decide whether that's you:
- It can find you. Your page has to be indexed (stored in the search engine's records) and reachable: by Google and Bing, and by the AI companies' own crawlers (programs that read websites automatically). If your site blocks them, loads its content only after a click, or hides prices behind tabs that never reach the page source, the assistant reads an empty page. I found exactly that on my own pricing page once: the prices for two-thirds of the services were invisible to AI crawlers because of how the tabs were built.
- It can understand you. The page has to say plainly who you are, what you do, where, and for how much, in sentences an AI can lift out and repeat without the rest of the page around it. "Family-owned, serving the area with pride since 1998" gives it nothing. "We install and repair tankless water heaters in Austin and Round Rock; the service call is a flat fee, credited to the repair if you go ahead" gives it a fact.
- It can trust you. The assistant leans toward facts it sees confirmed: the same name, address and phone across directories, reviews that say the same things your site says, and original numbers nobody else publishes. A page that repeats what every competitor says is interchangeable, and interchangeable pages get skipped.
That's the core of GEO: be findable, be quotable, be the source with the fact nobody else has.
What does GEO look like on a real business?
Theory is cheap, so here is what I measured on one client: a multi-location appliance repair business in the US. I don't name clients on this site.
I tracked the business with the same tool (Ahrefs Brand Radar), same settings, every few days between July 4 and August 18, 2026:
| What was measured | Start | Six weeks later |
|---|---|---|
| ChatGPT answers citing the business | 1 | 813 |
| AI answers citing it across all tracked engines | 63 | 2,605 |
| Change in AI answers vs. change in organic traffic | n/a | about 41x vs. 22% |
That last row is the one that convinced me GEO is real work and not a new name for SEO: AI presence multiplied while ordinary search traffic moved by a fifth. The full measurement series, including what I can and can't attribute to my own work, is in the AI SEO case study.
What did the work consist of? It was not tricks. The site grew from 64 pages to 1,174 pages earning impressions in Google: city pages, service pages and data pages built from the company's own job records: real repair prices, real failure rates by brand, real seasonal patterns. Every page states the business, the service and the area in its opening lines, answers the question in the first paragraph, and carries structured data (schema, hidden code that tells machines what's on the page). The original numbers did the heavy lifting: an AI can find a generic repair price range on a hundred sites, but it can only find this company's measured median on one.
Is GEO worth paying for if my customers don't use ChatGPT?
Your customers use it whether you see it or not, and that's the uncomfortable part.
On the same client site I installed a logger that records every request AI assistants make. Over five days it counted 813 live ChatGPT fetches: moments when ChatGPT opened one of the client's pages while answering a real person's question. Over the entire six weeks, the analytics tool recorded 26 visits from all AI platforms combined.
Read those two numbers together. AI assistants were reading the business's pages and passing its name along hundreds of times, and almost none of those people ever clicked through. They got the name, the price range and the phone number from the answer itself. If you judge AI search by your Google Analytics referral report, you'll conclude nobody uses it. Here, five days of live fetches outnumbered six weeks of recorded visits by more than thirty to one. I wrote up that gap in AI referral traffic in GA4.
The other number worth knowing: in a separate measurement, AI crawlers walked 1,703 URLs on two sites, and only 207 were ever pulled into a live answer. Most of those got pulled exactly once. Having pages isn't the same as being quoted; which pages AI pulls into answers shows what separates the two groups.
How do I get my business recommended by ChatGPT and AI Overviews?
If you want to start yourself before hiring anyone, these are the changes that move first, in the order I'd do them:
- Put the facts in the first two sentences of every service page. Who you are, what you fix or do, which cities, and a real price or price range. If a stranger read only those two sentences, could they book you?
- Publish one number nobody else has. Average repair cost from your own invoices, how many same-day jobs you complete, which brand fails most in your area. Original data is the single strongest reason for an AI to pick you over a competitor.
- Turn customer questions into headings and answer them directly below. "How much does it cost to replace a water heater in Phoenix?" followed by the answer, not by three paragraphs of introduction. I explain the structure in detail on answer engine optimization.
- Make your name, address and phone identical everywhere. Website, Google Business Profile, Yelp, BBB, industry directories. Inconsistency makes an AI less sure you're one business.
- Check that AI crawlers can actually read your site. Look at your
robots.txt, and check that prices and key text appear in the page source, not only after a click. - Measure it. Ask the assistants your customers would ask, every week, and write down who gets named. Better still, log which pages AI systems actually fetch, since that tells you what's working before any tool's sample does.
None of this is secret. What makes it hard is doing it across dozens or hundreds of pages, keeping the facts consistent, and knowing which change actually moved the result.
What do generative engine optimization services cost?
Prices across the market run from under $100 a month to five figures, and that spread isn't madness; it's four different products sold under one name: a monitoring dashboard, a content package, a technical rebuild, and a full system with measurement. I compare them line by line in what AI visibility costs.
My own prices are public, because I think hiding them is a bad sign in this market:
| What you get | Price | Time |
|---|---|---|
| Written diagnostic: the 3 to 5 problems doing the most damage on your site | Free | within 48 hours |
| Who's on the Map report: Google Maps, AI answers, the leaders and your website, measured and explained | $149 ($499/mo fixed and kept fixed) | 2 working days |
| AI visibility audit, four measured layers | $199 | n/a |
| GEO / AEO architecture: entity (how your business is described consistently everywhere), answers, original data, schema, measured across engines | from $2,000 | 3 to 6 weeks |
| Monthly system with attribution, so you can see which jobs came from it | from $1,500 / month | ongoing |
All of it is on pricing, with what each tier includes.
How do I choose a GEO agency or specialist?
Ask any provider (me included) these questions before you sign:
- Which AI engines do you measure, and how? "We track ChatGPT" isn't an answer. Which tool, how often, which prompts, and does the tool see all the engines your customers use?
- Can you show me a before-and-after from a real client, with dates? Numbers without dates and sources are decoration.
- What happens to my existing Google rankings? A provider who tells you SEO doesn't matter anymore is about to break the thing AI search depends on.
- How will I know if it brought me customers, not just mentions? This is the question most GEO services can't answer. Being named in an AI answer is a leading indicator, an early sign, while jobs and invoices are the result. I build the chain from the AI answer to the invoice in the CRM; it's described on full-cycle attribution.
- What do you do when the numbers stop growing? They will stop at some point. On the client above, the number of pages being cited stalled at 22 for weeks. Growth came back only when new, genuinely useful pages entered the set. Someone who has never hit that plateau will just sell you more blog posts.
If the answers are vague, the work will be too.
So, what is GEO in one sentence?
Generative engine optimization is making sure that when your customer asks an AI assistant who to call, the answer it writes contains your business's name, with facts accurate enough that the customer calls you.
The businesses that start now are competing against almost nobody, because almost nobody in their market knows the term yet. That window won't stay open: the number of people searching "what is generative engine optimization" in the US more than tripled in the last year, from 880 a month in September 2025 to 2,900 in August 2026 (Google Keyword Planner). Your competitors are starting to ask the same question you just did.
What to do with this
Start with the free steps in the list above: put who you are, what you do, which cities and a real price in the first two sentences of every service page, publish one number from your own jobs that nobody else has, and make your name, address and phone identical everywhere. Then ask ChatGPT and Google the questions your customers ask, every week, and write down who gets named. If you hire help, use the five questions in the previous section and insist on seeing how calls and jobs will be traced back to the work. Prices for my own work are on the pricing page.
I'm Ihor Odariuk. I do generative engine optimization end to end: making pages findable and quotable, getting the business named inside AI answers, and building the measurement that shows which of those answers turned into jobs. If you want to know exactly where ChatGPT, AI Overviews and Perplexity mention your business today, and where they name a competitor instead, send me your site for the free written diagnostic, or see how the work is done on AI citation visibility.
