SEO vs GEO: what's the difference, and do you need both?

Short answer: you need both, they are mostly the same work, and if you have to choose, fix your SEO first.

Longer answer below, because “mostly the same” is doing some work in that sentence and it is worth knowing which parts are not.

The one difference that matters

SEO is about your position in a list. GEO is about whether you are in the answer at all.

Google gives you ten results. Being seventh is not brilliant, but it is a page-one position and it earns work. Plenty of businesses have been built on being fifth.

An AI assistant gives you a paragraph naming two or three businesses. There is no fifth. There is named, and there is absent.

Everything else in this article follows from that.

What stays exactly the same

This is the larger part, and it is why I do not sell GEO separately.

Your site has to be fast and readable. A model crawling your site has the same problem a search engine does. If it is slow, if the content is locked in images or PDFs, if the structure is a mess, you are hard work.

You need a page for each thing you do. The single services page listing eight services was already bad for SEO. It is worse for GEO, because a model looking for “who does emergency hot water repairs in Blacktown” wants a page about emergency hot water repairs in Blacktown, not a paragraph inside a list.

Your details have to agree everywhere. Name, address, phone, identical on your site and every directory you appear in. This mattered for local SEO. It matters more for GEO, because cross-checking sources is much of what a model does before it commits to naming you.

Reviews still count. For both. What changes slightly is that the wording of reviews matters more for GEO than the star count, because a model reads them.

Schema markup still helps. Structured data telling a machine what you are, where you operate and what you offer. Useful for Google. Directly useful for a model trying to work out whether you serve the suburb it was asked about.

That is five of the roughly six things that matter. All shared.

What is genuinely different

Three things, and they are smaller than the marketing suggests.

1. Write so you can be quoted. A model lifting a sentence from your site wants a clean, self-contained claim. “We service all of the Hawkesbury and Penrith areas, seven days, with a two-hour emergency response” is quotable. “Servicing solutions tailored to your needs” is not quotable by anyone, about anything, which is a problem it already had.

2. Be unambiguous about who you are. Models get confused by businesses with common names, several trading names, or a services list that has drifted from what the business actually does now. Making it obvious you are one specific business in one specific place doing specific things is worth real effort.

3. Measure differently. There is no rank tracker. You measure GEO by asking the assistant the question your customer would ask and recording who it names. Then doing it again next month. That is genuinely the method, and it is why so many agencies are vague about reporting on it.

Side by side

	SEO	GEO
Where you appear	A list of ten results	One answer naming two or three
Second place	Still gets clicks	Usually gets nothing
What you optimise	Relevance and authority	Clarity and quotability
How you measure it	Rank tracking	Asking the AI, recording the answer
Traffic today, Australia	The overwhelming majority	A small but growing slice
Time to see movement	Three to six months	Weeks for fixes, months for the rest

How to tell which one you are losing on

Two checks, both free, both about ten minutes.

For SEO: search the thing a customer would search, in an incognito window, with your suburb in it. “Electrician Castle Hill”. Where are you? If you are not on page one, that is your problem and GEO is not the answer to it.

For GEO: open ChatGPT and Gemini and ask them the same question in plain language. “Who’s a good electrician in Castle Hill?” Are you named? If you are on page one of Google but never named by an assistant, that is a GEO gap and it is usually caused by something dull like inconsistent business details.

Most small businesses I look at are losing on both, and the SEO gap is bigger. That is the honest finding and it is not the one that sells expensive AI packages.

So, do you need both?

Yes, but not as two budgets.

Do the shared work properly, which is most of it, and you are most of the way to both. Then add the small GEO-specific layer on top: quotable writing, unambiguous identity, and actually checking what the assistants say about you.

That is why GEO is included in both of my SEO plans rather than sold as a separate service. Charging twice for the overlap would be hard to justify, and the overlap is the majority of the work.
