What is generative engine optimisation (GEO), and does a small business need it?

Generative engine optimisation, or GEO, is the work of making your content easy for AI tools like ChatGPT, Gemini, and Perplexity to find, trust, and quote when they answer a question. Where traditional search optimisation aims to rank your page in a list of links, GEO aims to get your business mentioned inside the AI's written answer. For most small businesses it is worth understanding and worth a little effort, but it is not a separate dark art, and nobody should sell it to you as one.

The term is new and the field is loud, so it is worth cutting through it calmly. This is the plain version: what GEO actually is, what the evidence says works, and how much a small business should reasonably do about it.

What GEO actually means

When you ask an AI assistant a question, it does not hand you ten links. It writes an answer, often pulling facts from several web pages and citing some of them. GEO is the practice of making your content one of those cited sources. You will also see it called answer engine optimisation (AEO) or AI search optimisation. The labels overlap and the industry has not settled on one, but they all describe the same goal: be part of the answer, not just the list underneath it.

How is it different from SEO?

Traditional search engine optimisation is about earning a click from a results page. GEO is about earning a citation inside a generated answer, where the reader may never click at all. The two are closely related, because most AI tools build their answers from the same web they always crawled, so a page that is well made for search is usually well placed for AI too. The difference is in emphasis. SEO has always cared about rankings and links. GEO cares most about whether a specific passage of your page can be lifted out and trusted on its own.

What the evidence says works

The most useful research here came from a team at Princeton, presented at the KDD conference in 2024. They tested a range of tactics across thousands of queries and found that the things which reliably improved how often content was cited were unglamorous: adding relevant statistics, quoting credible sources, citing references by name, and writing clearly and fluently. Keyword stuffing, the old spammer's trick, did nothing at all. The lesson is encouraging and a little dull: there is no hack. Clear, specific, well-sourced writing is what gets quoted.

The same research carried a finding that matters a great deal for smaller businesses. Because an AI judges the passage in front of it, a clear, well-structured page from a modest website can be cited ahead of a vague one from a much bigger competitor. The size of the brand behind a page matters less than it does in traditional search.

Does a small business actually need it?

Honestly, it depends on how your customers search. If people find you mainly through local searches and recommendations, the older fundamentals and a strong local presence matter more, and the good news is that doing those well sets you up for AI citation anyway. If your customers research their options by asking an AI, GEO is worth deliberate attention. Either way, the first move is the same: a clear, fast, well-written site that answers real questions. You do not need to buy a separate GEO product to get there.

What this means for your website

Treat GEO as an extension of doing the basics well, not a replacement for them. Answer the real questions your customers ask, near the top of the page, in plain words. Back your claims with specific facts and named sources. Keep your site fast and readable. That is most of GEO, and it is the same work that makes a site genuinely useful to a human being. This piece sits within how a business gets found in 2026, and the practical follow-through is part of the Get Found work we do once a site is live.
