What SEO and GEO are, and why they matter for small businesses

SEO and GEO are two acronyms you hear everywhere but nobody ever really explains. Together they decide one very simple thing: when a customer searches — on Google, or by asking ChatGPT — does your site show up, or does it not exist for them?

What they mean, in plain words

SEO stands for Search Engine Optimization: the set of choices that make your site easy to find and understand for search engines, so they show you to the right people. GEO stands for Generative Engine Optimization — the same idea, applied to AI assistants like ChatGPT, Perplexity and Google's AI answers. The mechanism is different: instead of ten links to choose from, the assistant gives back one answer, and either it names your site or it doesn't.

Neither is a trick, and neither is paid advertising: both are about making your site clear enough for whoever — a search engine or an assistant — has to decide whether to show it. Having a website is not enough on its own. If nothing understands what you do and who you help, it's like having a beautiful shop on a street where nobody walks.

How Google decides who to show first

When someone searches "seafood restaurant in Miami" or "B&B near the old town", the search engine picks in an instant which pages to put at the top. It mainly weighs three things:

• Relevance — does your page actually answer that search?
• Clarity — is the content readable, well-organised, and understandable for whoever (or whatever) has to interpret it?
• Trustworthiness — is the site maintained, fast, and do other sites mention it?

The more convincing you are on these points, the higher you rank. And the higher you rank, the more people see you: the difference between the first and second page of results is enormous — almost nobody reaches the second page.

What changes when the answer is just one

An AI assistant works on the same three ideas — relevance, clarity, trustworthiness — but it reads differently than a person scanning a results page. It needs content that states things plainly, structured with real headings, so it can lift a fact or a sentence and quote it with confidence. A page that is vague, or that hides the answer behind marketing language, is one an assistant can't safely cite — so it picks someone else's.

Why it matters (even) for a small business

It's often assumed that this is "for big companies". The opposite is true: for a local SMB it's one of the most cost-effective levers available. Someone searching "plumber in Austin" — or asking an assistant the same thing — already has a specific need. You don't need to convince them, you just need to show up before the others do. It's advertising that works for you every day, without paying per click.

Where to start

By understanding three things: which words your customers actually use to search, whether Google can read your site, and how your site shows up when people ask AI assistants instead. From there, everything becomes much simpler.
