Generative engine optimization (GEO) is the work of making your business more likely to be mentioned, quoted or cited in answers from AI assistants such as ChatGPT, Google’s AI Overviews, Perplexity and Gemini. It builds on SEO rather than replacing it: the same clear, trusted, well-cited content that helps you in search is what AI answers draw on.
Here’s where the term came from, how GEO differs from SEO, and what it means for a small business in practice.
GEO in one line
Generative engine optimization (GEO) means improving how often and how well AI-generated answers mention or cite your business and your website.
A “generative engine” is any tool that writes an answer for you, usually by searching the web and summarizing what it finds. ChatGPT search, Google AI Overviews and AI Mode, Perplexity and Gemini all work this way.
This post explains the term. For the full how-to across all four assistants, see our main guide on how to get your business mentioned by ChatGPT, Google AI and Perplexity.
Where the term came from
The term was introduced in a research paper first posted in November 2023, “GEO: Generative Engine Optimization”, by researchers including teams at Princeton University and IIT Delhi. It was accepted to KDD 2024, a major data science conference.
The authors built a test set of search questions, rewrote web pages in different ways, and measured how visible those pages became in AI answers. Their main findings:
- The best methods improved visibility by up to 40%, and by up to 37% in tests on Perplexity.
- Adding citations to credible sources, quotations and statistics worked best, improving visibility by roughly 30 to 40% on one of their two main measures.
- Making text easier to read and more fluent also helped, by 15 to 30%.
- Keyword stuffing, a classic old SEO trick, gave “little to no improvement.”
- Lower-ranked pages gained the most. In one test, adding citations raised visibility by 115.1% for pages ranked fifth in search, while it lowered visibility for pages ranked first.
These were controlled experiments on a benchmark, and AI assistants have changed a lot since. Treat the numbers as direction, not a promise. The broad lesson still holds up: clear, specific, well-sourced content gets used.
GEO vs SEO
| SEO | GEO | |
|---|---|---|
| Goal | Rank in search results and get clicks | Be named or cited inside an AI answer |
| Where it shows | A list of links | A written answer, with a few sources |
| How you measure it | Rankings, impressions, clicks | How often you’re mentioned or cited for a set of questions |
| What helps most | Useful pages, links, technical health | Useful pages, brand mentions on other sites, clear answers with sources |
| Free tools to measure | Google Search Console | Mostly manual checks, plus a few free checkers |
The overlap is large. Google says plainly that for its AI Overviews and AI Mode there are “no additional requirements” and no special optimizations needed beyond normal SEO. A page must be indexed and eligible for a snippet in Search.
Where GEO adds something is in two places. First, measurement: you have to ask the assistants your customers’ questions to see where you stand. Second, sources: AI answers draw on many pages, so being mentioned on other relevant sites matters a lot. In an Ahrefs study of 75,000 brands, branded web mentions correlated with AI Overview mentions at 0.664, compared with 0.218 for backlink count.
Other names for the same thing
- AEO (answer engine optimization): a common alternative name, often used to mean the same as GEO.
- LLMO (large language model optimization): the same idea, named after the technology.
- AI SEO or AI search optimization: a plain-English label for the same work.
The names are marketing labels, not standards. Don’t pay more for a service because it uses a newer acronym.
What GEO looks like for a small business
You don’t need a GEO agency to start. These six steps cover most of it, and the main guide linked above goes deeper on each.
- List the questions your customers ask. Ten to twenty real questions, in their words.
- Check where you stand. Ask each one in ChatGPT, Google, Perplexity and Gemini, and record who gets named and which sites are cited. Our guide on how to check if ChatGPT mentions your business has a tracking sheet.
- Let the crawlers in. Make sure your site doesn’t block Googlebot, OAI-SearchBot (ChatGPT search) or PerplexityBot. OpenAI says sites that opt out of OAI-SearchBot won’t be shown in ChatGPT search answers.
- Answer each question clearly on your site. Direct answer first, real numbers, sources linked.
- Get mentioned on the sites that are cited. Those are the pages the assistants already trust for your topic.
- Repeat monthly. AI answers change day to day, so look at the trend, not one result.
GEO myths to ignore
- “SEO is dead.” Google’s AI features use pages from its search index, and Google says normal SEO best practices still apply.
- “You need special AI files.” Google says you don’t need new machine-readable files, AI text files or special markup to appear in AI Overviews or AI Mode.
- “You must rank first to be cited.” Not necessarily. In a 2026 Ahrefs study of 4 million cited URLs, only 37.9% of the pages cited in AI Overviews also appeared in the top 10 results.
- “We can guarantee ChatGPT will recommend you.” No one controls what an assistant says. Anyone promising this is guessing.
How BuyLinks fits in
We focus on the two parts of GEO that are hardest to do alone: measuring and getting mentioned. Every plan includes a monthly AI visibility check, with 25 or more of your customers’ questions asked in ChatGPT, Google AI, Perplexity and Gemini, which comes to more than 100 answers checked. We record whether you’re named and which sites are cited, then choose publisher sites for your articles from the kind of sites the assistants already read.
We write every article and state each link’s label up front. Plans start at $199 a month; see our pricing. We can’t promise that any assistant will mention you, but we’ll show you the trend every month.
Frequently asked questions
Is GEO different from SEO?
It’s an extension of SEO. The goal shifts from ranking in a list of links to being named inside an AI answer, and measurement means checking the assistants directly. Most of the work, such as clear pages, a crawlable site and a good reputation on other sites, is the same.
Who invented the term GEO?
It was introduced in a 2023 research paper by researchers including teams at Princeton University and IIT Delhi, later accepted to the KDD 2024 conference. The paper defined GEO and tested methods for making pages more visible in AI answers.
How do I measure GEO results?
Keep a fixed list of customer questions and ask them in each assistant every month. Record whether you’re named, whether you’re linked and which sites are cited. Google says AI Overview and AI Mode traffic is included in your Search Console Performance report under the “Web” search type, not shown separately.
Is GEO worth it for a small business?
The basics are, because they’re the same steps that help you in normal search. Start with free checks and clear answers on your own site before paying for anything.
