What is GEO, and why does expert content get quoted by AI?

GEO, short for generative engine optimization, is the work of making your content the source an AI answer quotes. When a buyer asks ChatGPT, Claude, Perplexity or Google a question, the assistant often searches the web, reads a few pages and writes one answer from them. GEO is about being one of those pages, and being the part that ends up in the answer.

Where the term comes from

The name comes from a research paper, GEO: Generative Engine Optimization, by researchers from Princeton, IIT Delhi and others, accepted at the KDD conference in 2024. They call AI search tools generative engines: systems that find sources and write a response grounded in them, instead of showing a list of links.

That changes what winning means. In classic search you want to rank. In an AI answer, a buyer may never see a list of results at all. What matters is whether your content shapes the answer and is cited as a source.

What made content show up more

The researchers built a test set of 10,000 queries, tried nine ways of rewriting a web page, and measured how much of each page made it into the generated answer.

• Citing sources, adding quotations and adding statistics worked best: 30 to 40% more visibility on their main measure.
• Keyword stuffing, the classic SEO trick, gave little to no improvement.
• On Perplexity, a live AI search engine, the gains reached up to 37%.

It is one study, on the authors’ own test set, and the effects differed by subject. Read it as a direction, not a guarantee. But the direction is clear: in this study, engines picked up content that brings something checkable, a source, a quote, a number, more than content that repeats the keywords of the question.

What Google says about AI answers

Google is just as direct. Its guidance on AI features says there are no additional requirements to appear in AI Overviews or AI Mode, and no special schema.org markup you need to add. The SEO basics still apply: let crawlers in, and make sure any structured data matches what is on the page.

What Google does ask for is in its guide to helpful content. It asks whether content shows first-hand expertise and a depth of knowledge, and it encourages clear bylines, so readers know who wrote it. One of its questions sums it up:

Why expert content gets quoted

An AI answer is built from what has already been written. A post generated from the same public text adds nothing the engine doesn’t already have, so there is little reason to quote it.

Your experts know things nobody has written down yet. The price range your security consultant explains on every intake call. The mistake your consultant sees at every new client. The trade-off your founder walks every buyer through. That is first-hand, specific and tied to a named person: the kind of source, quote and number that did well in the GEO study, and the original information Google asks for.

The study didn’t test expert content as such; it tested what a page contains. But a real answer from a real expert is where those ingredients come from in the first place.

What about AI-written posts?

AI isn’t the problem. Google says it rewards high-quality content however it is produced, and that using AI mainly to manipulate rankings is spam.

The Orbit Media survey of 1,042 content marketers from 2026 shows the same from the other side. 92% of them use AI, and they are no more likely to report strong results than the 8% who don’t. The single best predictor of strong results was collaborating with experts and influencers: marketers who do it beat the benchmark by 2.6 times. It is self-reported, and a correlation, but it points the same way.

So use AI for what it is good at: structure, formats and SEO. Keep the substance human.

How to start with GEO

1. List the questions buyers ask before they talk to you. Sales knows them.
2. Let the expert who knows the answer give it, in their own words, with the numbers and examples they really use.
3. Publish each answer on your own site as its own page, under the expert’s name, with the question as the heading.
4. Let AI crawlers in. Check that your robots.txt and your CDN don’t block them.
5. Keep a rhythm. One question a week is 52 answers per expert in a year.
6. Ask your buyers’ questions in ChatGPT, Claude and Perplexity yourself, and see who gets quoted.

That is the work Unmuter does for you. Max asks each expert one question a week, they answer with a voice note or video, and six AI agents turn it into a blog in their own words, with every quote checked against the recording. You approve before anything goes live.
