Generative engine optimization is the practice of making a business or a page more likely to be retrieved, cited and named inside an answer that an AI system generates, rather than only ranked in a list of links beneath it.
- The term has a birthday. It was coined in a November 2023 research paper, not by an agency.
- The original research was about documents, not businesses. Anyone quoting its headline number at a local contractor is misapplying it, and we explain why below.
- The practice is largely familiar work. Retrievability, clarity, corroboration. The scoreboard changed more than the sport did.
- It cannot be guaranteed. Generated answers are probabilistic. Anyone promising placement is selling certainty they do not have.
An academic paper, not a marketing department
Most acronyms in this industry are invented by whoever wants to sell the thing. GEO is an exception, which is worth knowing when someone tells you it is made up. The term was introduced in a paper titled GEO: Generative Engine Optimization, submitted to arXiv on 16 November 2023 by Pranjal Aggarwal, Vishvak Murahari, Tanmay Rajpurohit, Ashwin Kalyan, Karthik Narasimhan and Ameet Deshpande.
The researchers built a benchmark they called GEO-bench, a large set of user queries paired with the web sources a generative engine might draw on, and tested which edits to those source documents made a generative engine more likely to feature them. Their headline finding, quoted exactly: “GEO can boost visibility by up to 40% in generative engine responses.” They also found that what works varies by domain, which is the part everyone skips.
Then the acronym escaped. Within a year “GEO agency” was a category with a price list, and the 40% figure had been pasted into a great many sales decks aimed at people who install fences and replace roofs.
Why we do not quote the 40% at you
That study measured what happens when you edit a document that the engine was already considering for an informational query, and then re-ran the engine against a benchmark. It is good research and it is not a claim about whether ChatGPT will recommend your plumbing company in your metro.
Two different things are being confused. One is content optimisation: given that a source is in play, make it more quotable. The other is entity recommendation: get named at all when someone asks who to hire. The second is mostly decided before any of your page copy is read, by whether you are a verifiable business, whether your details agree across the web, and whether other sources corroborate you.
So GEO, applied to a local service business, is the smaller half of the job. It matters. It is not the whole discipline, which is why we file it under AI visibility rather than treating it as the category name.
What GEO actually consists of
Answer-first structure. Put the answer in the first two sentences under the heading that asks the question. A generative engine composing a response will lift a clean, self-contained statement long before it will paraphrase paragraph nine.
Specificity over adjectives. “We install cedar privacy fence in Cobb and Cherokee counties, typically 5–8 working days from deposit” is retrievable. “Quality workmanship you can trust” is not a fact and cannot be cited.
Quotable evidence. Numbers, dates, named sources, direct statements. The 2023 research found that adding citations, quotations and statistics to a source measurably improved its odds of being featured, which matches what you would expect from a system that has to defend its answer.
Coverage of the actual question set. Not keywords, questions. What a homeowner asks before they buy, written out and answered plainly, including the ones with awkward answers.
Machine-readable structure. Real headings, real lists, schema that describes what is on the page. Structure helps extraction. It does not manufacture authority, and marking up things that are not there is how profiles get into trouble.
Where this term ends and the next one begins
How you would know GEO is working
There is no rank tracker for a sentence that rewrites itself every few days, so the measurement has to be built rather than bought. The unit we publish is X out of 12: twelve real buying questions for your trade and market, asked on Google AI Overviews, ChatGPT and Perplexity, each repeated three times in clean sessions, counted only where you are named in at least two of three runs.
Per platform. Dated. With screenshots. Re-run monthly, because a single run proves nothing in either direction. The full protocol is published so you can run it yourself or audit anyone else’s number against it.
Treat any percentage without a published question set the way you would treat a quote with no scope of work. We publish our own results, including the bad months: our numbers are here.
This page defines a term. It does not sell anything. If you want to see how this work is actually run, what is in it, what it costs, what gets measured, that lives on the AI Visibility service page.

Fair questions about GEO
Is GEO a real discipline or a rebrand?
Both, honestly. The underlying work is largely the work good SEO always described, so the cynics have a point. But the thing being optimised for changed, a synthesised answer that names two or three businesses behaves differently from ten blue links, and it needs its own measurement because the old one does not fit. Rebrand of the label, real change in the target.
Do I need a GEO agency separate from my SEO agency?
No, and splitting them tends to produce two invoices arguing over the same page. The signals overlap almost entirely. What you should insist on is that whoever holds the work can show you a measurement method for the AI layer that survives a follow-up question.
Does adding statistics and quotes to my pages help?
That was one of the clearer findings in the original research, and it is consistent with how these systems behave, a model composing an answer it has to stand behind prefers sources that state something checkable. The caveat is that the statistics have to be true and attributed. Invented precision is worse than no number.
Can anyone guarantee my business appears in ChatGPT?
No. Outputs vary between runs, accounts, regions and weeks, and nobody outside the model provider controls them. What can be done is building the signals that make you safe to name, then measuring honestly whether it is working. Anyone selling the guarantee is charging you for their own uncertainty.
How long does GEO take to show up?
Fixing something broken, a blocked crawler, a wrong address, a page with no answer in it, can move within weeks because you are removing an obstacle. Building presence where there was none is a months-long, non-linear climb that can go backwards for a month while the inputs improve. Which is exactly why the baseline gets taken first.
