What is AI visibility? A plain-English guide for Costa del Sol businesses

If you have heard the term “AI visibility” and are not quite sure what it means, you are in good company. Most business owners on the Costa del Sol are in the same position. This article explains it plainly, without jargon, and tells you what to do about it.

The short definition

AI visibility is the measure of whether your business gets named, accurately and favourably, when a potential customer asks an AI assistant a question related to what you do.

When someone asks ChatGPT “can you recommend an estate agent in Marbella for British buyers?”, the AI produces a short answer naming a few agencies and explaining why. If your agency is in that answer, you have AI visibility for that question. If it is not, you are invisible at the exact moment a buyer is making a decision.

That is the whole concept. Everything else is detail.

Why it matters now

Until recently, when people wanted a product or a service they typed a query into Google and clicked one of the blue links. The businesses that ranked at the top of that list won the customer. That is SEO, and it still matters.

But behaviour is changing. More people, especially younger buyers and international researchers, now ask an AI assistant their question in plain language. They get a single answer, not a list of links. They read the answer, and they act on it. Often they never click through to a website at all.

If your business is not in that answer, you are not in the consideration set. It does not matter how good your website is, because the customer never visits it.

The three engines that matter

There are three AI engines your customers are likely to use today:

1. ChatGPT, by OpenAI. The most widely used AI assistant. It searches the web and produces answers with citations.
2. Gemini, by Google. Built into Android phones, Google Search results and Google’s own AI Overviews.
3. Perplexity. An answer engine built specifically for search, with source citations for every claim.

Google’s AI Overviews, the generated answers that appear at the top of Google Search on many queries, are a fourth surface that sits between traditional search and AI answers. They all draw on similar sources, but they do not always produce the same answer. That is why we track all three.

How AI decides who to name

AI engines do not have a list of “the best estate agents in Marbella” stored somewhere. They generate each answer on the fly, by searching the web, reading what they find, and synthesising a response. The businesses that get named are the ones the model can describe with confidence, because enough trustworthy sources describe them consistently.

The sources the model reads include your own website, but they also include review sites, directories, press articles, social media, government registers and forums. In fact, for many questions, third-party sources carry more weight than your own site, because the model wants corroboration. It wants to see that independent sources agree on what your business is and does.

This is the biggest shift from traditional SEO. In SEO, your own website is the thing you optimise. In AI visibility, your own website is one source among many, and the model is looking for agreement across sources.

What it is not

AI visibility is not a replacement for SEO. The two build on each other. A fast, well-structured website with clear content helps both your Google rankings and your AI visibility. A healthy Google Business Profile helps both. Genuine reviews help both.

Nor is AI visibility a one-off fix. The models update, the web changes, and competitors improve their own visibility. The businesses that stay visible are the ones that check their AI answers regularly and keep improving the sources the models read.

It is also not about tricking the AI. The models are trained to resist manipulation. The sustainable way to gain visibility is to make accurate, consistent, trustworthy information about your business available across the sources the models read. That is harder than it sounds, and it is most of what we do.

What a Costa del Sol business should do

Start simple. Pick ten questions your best customers would ask, in their own language. Put them to ChatGPT, Gemini and Perplexity. Write down who gets named and why. If you are named, note whether the description is accurate. If a competitor is named instead of you, that gap is your to-do list.

Then work on the sources. Make sure your own website describes your business clearly and factually. Complete your Google Business Profile. Earn reviews that mention specifics. Get listed in the directories and publications your sector relies on. Keep your descriptions consistent across all of them.

Finally, track your AI answers over time. A monthly check across the three engines, on the same ten questions, tells you whether you are gaining or losing ground. That is what we do for our retainer clients, and it is the only reliable way to know where you stand.

If you want a starting point, our free AI visibility check tests ten questions across three engines and compares you with three competitors. No cost, no obligation, just a clear picture of where you stand today.
