What is GEO?
Published · Updated
GEO — Generative Engine Optimization — is writing your pages so a generative AI builds its answer out of your words. Not a link under the answer. The answer itself: the sentence ChatGPT, Gemini, Perplexity, Copilot, or Google's AI Overview types out for a person who asked a question you already know how to answer.
The term comes out of academic work published in 2023 — researchers took a set of real questions, ran them through generative search engines, and tested which changes to a page made it more likely to appear inside the generated response. That's the whole idea: not guessing what a machine likes, but writing in the shapes that measurably survive the trip into an answer.
SEO, AEO, GEO — three words, one direction
Get ranked
You want to be one of the links. Success is a position in a list, and a click.
Get cited
You want to be the source under the answer. Success is your name in the citation.
Get used
You want your material inside the sentence. Success is the answer being made of your facts.
They aren't rivals. An assistant can't use a page it can't reach, so the technical hygiene of SEO still comes first, and the clear question-and-answer structure of AEO is what makes a passage liftable. GEO is the writing layer on top: what's actually in the sentences.
What the research found moves the needle
Nine tactics were tested against generative engines. Three stood out, two helped, and the oldest trick in search did nothing at all.
Quote a real person
A sentence attributed to a named expert, customer, or inspector is quotable as a unit. Research found quotations among the strongest single changes you can make.
Cite your sources
Link the study, the code, the manufacturer spec. Generative engines lean on material that shows where its facts came from, because that's what they have to reproduce.
Include real numbers
"Most jobs" is unusable. "Nine of the last ten jobs finished in under three days" is a sentence an assistant can lift whole.
Write plainly
Short sentences, ordinary words, one idea each. Fluent text is easier for a model to absorb into an answer without mangling it.
Be specific and complete
Answer the whole question on one page — cost, timeline, what's included, what isn't. Half an answer gets combined with somebody else's other half.
Skip the keyword stuffing
Repeating a phrase did nothing measurable in testing, and it makes the page worse to read. The old trick doesn't transfer.
A five-step version you can do yourself
- 1
Pick the five questions you get asked most
Not the ones you wish people asked. The actual ones, in the words they use on the phone.
- 2
Give each one a heading and a direct answer
Heading phrased as the question. First sentence is the answer, with the number in it.
- 3
Add one quote and one source per page
A line from a customer or a supplier, and a link to whatever proves the claim you just made.
- 4
Put a date on it
Published and updated, visible on the page. Undated pages get treated as maybe-stale.
- 5
Ask the assistants once a month
Same questions, same wording, three assistants. Write down who gets named and what they say about you.
The honest caveats
Nobody can guarantee a mention in a generated answer, and anyone who says otherwise is selling something. The models change, the citation rules change, and two people asking the same question can get different answers on the same afternoon. What you can control is whether your page contains a clear, dated, sourced, quotable answer to the question you want to be known for — which is worth doing whether or not a machine ever reads it.
Common questions
What is GEO?
GEO stands for Generative Engine Optimization: shaping your content so a generative AI — ChatGPT, Gemini, Perplexity, Copilot, Google's AI Overviews — pulls your words into the answer it writes for a user. The term comes from 2023 academic research on how AI answers pick their sources.
What's the difference between SEO, AEO, and GEO?
SEO earns a ranking in a list of links. AEO earns a citation as the source of an answer. GEO goes one step further: it shapes how your content is written so the generated sentence itself is built from your material. They overlap, and doing all three well mostly means writing more clearly.
What actually works for GEO?
The original research tested nine tactics. Adding quotations from credible people, citing sources, and including relevant statistics moved visibility in generated answers the most — often 30 to 40 percent. Keyword stuffing did nothing or hurt.
Does GEO mean writing for robots instead of people?
No. Everything that helps here — a direct answer up front, a real number, a named source, a plain sentence — also helps a human skimming the page. Content written only for machines tends to read badly and get skipped by both.
How do I check whether GEO is working?
Ask the assistants directly. Type the question a customer would type into ChatGPT, Perplexity, and Google's AI mode, and see whose words come back. Repeat monthly and keep notes — the answers move, and so does who's inside them.
How long does GEO take?
Weeks to months. Some assistants read live pages and can reflect a change within days; others rely on a training snapshot that refreshes on its own schedule. Consistency across your pages speeds it up more than any single edit.
Is GEO only for big brands?
No — small, specific sites often do better. Generative engines reward a page that answers one narrow question completely. A local shop's honest page about its own prices and process can beat a national site's vague overview.
