What generative engine optimization is, in plain words
This page is for the owner of a local business who has asked ChatGPT about their own trade and not seen their name. After reading it you will know what the assistants read, why a business gets left out, and how to test yours.
In one paragraph
Generative engine optimization is the work of getting your business named, with the right facts attached, inside the paragraph that ChatGPT, Gemini, Copilot or Perplexity writes when a customer asks for a recommendation. It is not ranking in Google and it is not winning a snippet box. The assistant runs a search, reads a few of the pages it finds, and writes a few sentences naming the businesses that fit. Your job is to make the facts about your business clear, consistent and reachable by the crawlers those assistants use, so that when a traveler asks for an RV park near Yellowstone with 50-amp sites, yours is one of the names.
What generative engine optimization is
When a customer types a question into ChatGPT, Gemini, Copilot or Perplexity, the assistant does not show ten blue links. It runs a search behind the scenes, reads a handful of the results, and writes a paragraph. If the question is about where to stay, that paragraph names two or three businesses. Generative engine optimization, GEO for short, is the work of being one of those names, with the right town, the right phone number and the right facts attached.
The search behind the scenes is a real search index. ChatGPT search results come from Bing’s index and from OpenAI’s own crawler. Gemini draws on Google Search. Copilot uses Bing. Perplexity runs its own index with Bing as a supplement. Google’s AI Overviews and AI Mode use Google’s index. So a page that no search engine has indexed will never be read by an assistant, and a page Bing has never crawled is invisible to two of the four. The index each assistant uses is the first thing to understand.
Winning the answer box at the top of a Google result is a separate job that belongs to featured snippets. GEO is about being read by the assistant and being clear enough to quote.
What being left out of AI answers looks like for an RV park
Madison Bend RV Park sits two miles from the west entrance of Yellowstone. It has 84 sites, 61 of them full hookup with 50-amp power, and a nightly rate of $58 from May through September. It has 4.7 stars on Google from 312 reviews, and it fills most nights in July.
A traveler planning the drive from Boise opens ChatGPT and asks where to park a 40-foot fifth wheel near West Yellowstone in September. The answer names three parks. Madison Bend is not one of them. When the owner asks the same question, the assistant names a park that closed in 2023 and a campground thirty miles up the highway that has no sewer hookups.
Nothing is wrong with the park, only with the trail of facts it leaves. The website says the park is big rig friendly but never states a site length or an amp rating. The Google Business Profile lists it as a campground rather than an RV park, and the phone number there differs from the one on the site by one digit. Bing has indexed two of the site’s eleven pages. The assistant had nothing solid to quote, so it quoted someone else.
A worked example: getting an 84-site park in West Yellowstone named by ChatGPT
The owner of Madison Bend asked ChatGPT, with search turned on, the question a customer would ask. The prompt was: I’m pulling a 40-foot fifth wheel and need full hookups with 50 amp near West Yellowstone in mid September. Where should I stay? Here is the answer before any changes were made to the site or the business profile.
Two parks near West Yellowstone are commonly recommended for large rigs: Gallatin Pines RV Resort and the Hebgen Lake campground. Both offer full hookups, though availability in September can be limited. You may also consider Rainbow Point Campground, though it typically closes in mid September and does not offer sewer hookups. Booking ahead is strongly advised.
Five facts were then fixed so that the site, the Google Business Profile and the two directories that mention the park all said the same thing.
| Fact | Before | After |
|---|---|---|
| Business category | Campground on Google, RV park on the site | RV park everywhere |
| Site length | “Big rig friendly” | Pull-through sites up to 75 feet |
| Power | Not stated | 61 full-hookup sites with 50-amp service |
| Season | “Open summer” | Open May 1 through October 15 |
| Phone | Two numbers, one digit apart | (406) 555-0147 on every listing |
The same prompt was run again a month later.
Madison Bend RV Park in West Yellowstone, about two miles from the park’s west entrance, has 61 full-hookup sites with 50-amp service and pull-through sites up to 75 feet long, which will fit a 40-foot fifth wheel with a truck attached. Nightly rates are $58 in September and the park stays open through October 15. Reservations are taken at (406) 555-0147 or on the park’s website. Gallatin Pines RV Resort is another option nearby with full hookups.
Every fact in the after paragraph appears word for word on the park’s site. The assistant did not invent anything. It found clear sentences and repeated them. In our testing that is the pattern across all four assistants: a business gets named when its facts are plain enough to lift, and gets skipped when they are not.
How to check your own business in ChatGPT, Gemini and Perplexity
- Write down the question a customer would ask, with the town, the specific need and the season in it. Best RV park near West Yellowstone with 50 amp in September is a real question. RV park Montana is not.
- Ask it in ChatGPT with search turned on, in Gemini, in Copilot and in Perplexity. Use a fresh chat each time so your earlier conversations do not shape the answer.
- Record whether you were named, which facts were attached to your name, and which competitors were named instead.
- Click the sources the assistant shows. Note whether any of them is your own site or your Google Business Profile.
- Search Bing for
site:yourdomain.comand count the pages it returns. Then do the same in Google. If Bing shows far fewer, ChatGPT and Copilot are reading a thin version of your site. - Repeat the same five prompts once a month and keep the answers in a spreadsheet. That log is the only measurement of mentions that exists, and measuring GEO covers how to read it.
What we do about generative engine optimization
You will get a written record of what each of the four assistants says about your business today, for the ten questions your customers actually ask, along with the competitors being named in your place. Then the facts on your site, your Google Business Profile and the directories that mention you will be brought into line, stated in sentences an assistant can quote, and submitted to both Google and Bing. Each month you will see the same ten prompts run again, with the change in mentions and the visits from AI assistants pulled from your Google Analytics. This is part of every site audit, which is where the work starts.
Questions people ask about GEO: what generative engine optimization is, in plain words
What is generative engine optimization?
Generative engine optimization is the work of getting a business named correctly in the answers written by AI assistants such as ChatGPT, Gemini, Copilot and Perplexity. Those assistants run a search, read a few pages, and write a paragraph naming businesses, and GEO makes sure your facts are clear enough to be one of them.
Is GEO the same as SEO?
No, GEO and SEO are related but not the same. SEO gets your pages into the search index and up the rankings, and GEO gets your business named inside the paragraph an assistant writes from those pages. SEO comes first and GEO builds on it.
How do AI assistants find local businesses?
AI assistants find local businesses by running a search in a real index and reading the pages that come back. ChatGPT and Copilot use Bing's index, Gemini and Google's AI Overviews use Google's, and Perplexity runs its own index with Bing as a supplement. A business missing from those indexes will not be named.
Do I need GEO if I already rank on Google?
Yes, ranking on Google does not guarantee an assistant will name you, because two of the four major assistants read Bing rather than Google and all of them need facts stated plainly enough to quote. A page that ranks well but says nothing specific about site length, price or hours will be read and skipped.
Can a business be named in ChatGPT without a website?
A business can be named without a website if its Google Business Profile and a few directory listings state the same facts, but in our testing it is rare and the facts attached are often wrong. Without a site, the assistant is quoting whatever a directory happened to record.
