SEO vs GEO: What's the Difference and Why Does It Matter?

SEO gets you found on Google. GEO gets you recommended by AI. Here's why you need both — and why most businesses are missing one entirely.

The question we get asked most often is simple: "We already do SEO — why do we need GEO?"

It's a fair question. And the honest answer is that SEO and GEO are complementary, not competing. But they work in fundamentally different ways, and assuming one covers the other is costing businesses real customers.

How traditional SEO works

Search Engine Optimization is built around one goal: getting your website to appear as high as possible in Google's list of results when someone searches for a relevant term.

To do that, SEO focuses on:

• —Keywords — matching the words people type into the search bar
• —Backlinks — earning links from other websites to build authority
• —Technical health — making sure Google can crawl and index your site correctly
• —On-page signals — title tags, meta descriptions, heading structure

When it works, someone searches "accountant in Manchester", your site appears near the top, they click the link, and they land on your website.

How AI search works differently

AI search tools — ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot — don't show a list of links. They read, synthesise, and summarise content from across the web, then give the user a direct answer.

When someone asks ChatGPT "who's the best accountant in Manchester for small businesses?", the AI doesn't serve up ten blue links. It recommends specific businesses by name, with reasons why.

That recommendation is based on a completely different set of signals than traditional SEO:

• —Entity clarity — does the AI clearly understand what your business is and does?
• —Content authority — does your content demonstrate deep expertise in your field?
• —Structured data — have you given AI tools machine-readable information about your business?
• —Trustworthiness signals — are you cited, referenced, or mentioned across authoritative sources?

The gap most businesses have

Here's what makes this urgent: a business can rank #1 on Google and still be completely invisible to AI search tools. And a business with modest Google rankings but strong GEO can be recommended constantly by AI.

These are different games, with different rules.

Most businesses have invested years in SEO. Almost none have invested anything in GEO — because until recently, GEO didn't exist as a defined discipline.

Why you need both

We're not suggesting you abandon SEO. Google still handles billions of searches per day and traditional search isn't going anywhere soon.

But AI search is growing fast. A significant and increasing share of your potential customers are now starting their buying journey by asking an AI tool a question. If you're not optimised for that, you're invisible to them.

The good news: GEO builds on top of SEO. Strong content, a well-structured site, and genuine expertise are the foundation of both. GEO takes that foundation and extends it — adding the structured data, entity signals, and content architecture that AI tools specifically look for.

You don't start from scratch. You layer on top of what you have.

The bottom line

SEO = get found when people search Google.

GEO = get recommended when people ask AI.

Your customers are doing both. Make sure your business shows up in both.
