GEO vs SEO: What Is the Difference, and What Does Your Business Need?
GEO vs SEO (also called AIO or AEO): where each makes you visible, what you measure, where the work overlaps and what your business needs first.
Quick answer
You rarely have to choose: for most businesses SEO comes first and GEO is added on top, because Google says its AI features use the same index and that SEO fundamentals still apply. What really differs is measurement. SEO is tracked in positions and clicks; GEO by testing the same buyer questions in AI tools every month and counting mentions, recommendations and citations, since no provider publishes rankings or timelines for AI answers.
SEO aims at a place in the list of search results; GEO aims at being named, recommended or cited inside an answer written by an AI system.
You will also see the same work called AIO (AI optimisation) or AEO (answer engine optimisation).
On this site we use GEO.
The two share most of their foundations, and for most businesses the question is not which one to choose but in what order.
This article compares them side by side and helps you decide.
What GEO is in detail is covered in What Is GEO?.
What Is the Difference Between GEO and SEO?
SEO is measured in positions and clicks: where your page appears for a search, and how many people visit it.
GEO is measured in answers: whether an AI system names your business, suggests it, or shows your page as a source when someone asks a question.
The other big difference is how much is published.
Google documents a great deal about how its search results work and gives you Search Console to see your positions.
For AI answers, no provider publishes how sources are chosen or how long changes take, so measurement has to be done by testing questions yourself.
| SEO | GEO | |
|---|---|---|
| Where you appear | In the list of search results and the map results | Inside answers from Google AI Overviews and AI Mode, ChatGPT search, Perplexity |
| What success looks like | A high position and a click to your site | Your business named or recommended, or your page cited as a source |
| How you measure it | Search Console, rank tracking, analytics | A fixed set of buyer questions tested every month |
| What is published | Extensive Google documentation | Access rules and basic requirements only; no selection criteria |
| Typical timeline | In our SEO work, first signals after 8–12 weeks, a clear effect after 4–8 months | No provider publishes one; judge against your own baseline |
| Main work | Pages, technical health, links | The same, plus consistent facts across the web and answer testing |
Where Do GEO and SEO Overlap?
More than most sales pitches admit.
Google says there are no extra requirements to appear in AI Overviews or AI Mode, that a page has to be indexed and eligible to show with a snippet, and that existing SEO fundamentals continue to be worthwhile.
Other AI tools that search the web also need pages they can reach and read.
- Pages that can be crawled and indexed.
- Clear headings and a direct answer at the top of each page.
- One consistent description of the business everywhere it appears.
- Mentions and links from independent, credible websites.
- Structured data that matches what the page shows.
Good GEO is mostly good SEO measured in a new place. The difference is in what you track, not in a separate set of tricks.
What Does GEO Add on Top of SEO?
Three things are specific to GEO, and none of them is a hidden ranking factor.
- Answer testing: a written set of buyer questions run in the AI tools your customers use, with the answers kept month by month.
- Separate counting: mentions, recommendations and citations recorded separately, because they mean different things.
- AI crawler access: checking that crawlers such as OpenAI's OAI-SearchBot are not blocked, alongside Googlebot.
Does Your Business Need GEO, SEO, or Both?
Start from how your customers find you today.
Ask your last ten new clients how they first heard of you.
If nobody mentions an AI tool, SEO and Local SEO come first and GEO can follow.
If several say they asked ChatGPT or read an AI Overview, AI visibility deserves its own measurement now.
- A local service business (plumber, clinic, restaurant): Local SEO and the Google profile first; add GEO measurement once the basics are in place.
- A firm selling a considered service (law, accounting, consulting, B2B): SEO first, with GEO testing early, because a long research phase gives buyers more chances to ask an AI tool.
- A business with little web presence: SEO first. There is little for any AI system to find until your own pages and listings exist.
- A business already strong in search: test the AI answers now; you may already be named, and knowing your baseline is cheap.
How Should You Split the Budget?
Because the foundations overlap, you do not need a separate team.
With us, SEO costs from €550 a month, Local SEO from €350 a month, and AI & GEO from €400 a month, all plus VAT with a six-month minimum.
Many businesses begin with SEO or Local SEO and add GEO once the site and profile are in order.
The practical steps are in our guide to appearing in ChatGPT answers.
Whether SEO still pays off when people use AI is discussed in foundational SEO with AI.
GEO and SEO aim at different places on the screen but stand on the same ground. Build the ground once, measure both places, and decide where to put extra effort from your own numbers rather than from predictions about AI.

Will GEO replace SEO?
Not on current evidence. Google's AI features draw on its search index, and Google says SEO fundamentals continue to be worthwhile for them. GEO depends on that base.
Can I do GEO without SEO?
Only partly. Consistent facts and independent mentions help on their own, but if your pages cannot be found and indexed, there is little for AI systems that search the web to draw on.
Does ranking first on Google mean I appear in AI Overviews?
No. Being indexed and eligible for a snippet is required, but Google does not publish how it picks the pages shown with an AI Overview, and a top position does not guarantee inclusion.
Do I need a separate GEO team or agency?
No. The same people who look after your SEO and content can add answer testing and the consistency work. What matters is that someone owns the monthly measurement.
How do I measure GEO and SEO side by side?
Use Search Console and analytics for SEO. For GEO, run the same buyer questions in the AI tools every month and record mentions, recommendations and citations separately, next to your enquiries.
