GEO vs SEO: the real differences

More and more clients come to us with the same doubt: they have spent years hearing about SEO, now they are being told about GEO, and they cannot tell whether it is the same thing under a new name or whether they are being sold the same thing twice. Let us clear it up without jargon.

The difference in one sentence

SEO (Search Engine Optimization) is the work of getting your website to appear in Google’s list of results when someone searches for what you sell. The aim is to hold a place in that list of blue links and for the person to click through to your site.

GEO (Generative Engine Optimization) is the work of getting an artificial intelligence system — ChatGPT, Gemini, Perplexity, Copilot, or the AI summaries Google shows at the very top — to mention you inside the answer it writes. There is no list here: there is a paragraph written by the machine, and the question is whether your business is named in it or not.

Put another way: in SEO you compete for a position; in GEO you compete for a mention.

The table: what changes from one to the other

	SEO	GEO
Where you appear	In a list of results, with your link	Inside a text written by the AI, cited as a source
What you optimise	A whole page for a specific search	Individual paragraphs and fragments the AI can extract and reuse
How success is measured	Position on Google, incoming visits, clicks	Whether you are named, in which questions, and how often
What content is rewarded	Complete content, with depth, answering thoroughly	Direct, self-contained, verifiable answers
Which signals weigh most	Links from other sites, speed, technical structure, domain authority	Clarity, concrete verifiable facts, consistency between what you say on your site and everywhere else
Who decides	An algorithm that ranks links	A model that writes and chooses whom to name
How the customer arrives	Clicks and lands on your site	May come through the cited link, or arrive already convinced after reading your name

What each one optimises, in practice

SEO works on the whole page. A well-ranked page is one that covers a topic thoroughly, loads fast, looks right on a phone, has an orderly structure of headings and receives links from other sites Google considers trustworthy. Google evaluates it as a whole and decides where to place it in the list.

GEO works on the fragment. A generative engine does not show your page: it reads it, extracts the sentences it finds useful and blends them with what it has read elsewhere to build an answer. That is why, in GEO, every paragraph has to stand on its own. If one of your paragraphs only makes sense after reading the three before it, the AI cannot use it.

That is the most important practical difference: in SEO you write for someone who is going to read the page; in GEO you write so that a machine can tear off a piece and have that piece still make sense out of context.

How success is measured in each case

SEO has clear, long-established numbers: what position you appear in, how many people come in from Google, which pages attract the most visits. It is a mature field with well-tested tools.

In GEO, measurement is younger and less precise. What you observe is whether the model names you when asked a question typical of your sector, what words it uses to describe you, and whether the description is correct. There is no “position 3” to lean on: there is a presence that either shows up or does not, and that can vary from one query to the next.

This has an honest consequence worth stating: GEO is measured worse than SEO and is still changing fast. Anyone promising you a guaranteed spot in ChatGPT’s answer is selling smoke.

What kind of content each one rewards

SEO rewards depth. One extensive guide that resolves an entire topic usually beats five short, scattered articles.

GEO rewards extractable clarity. Clean definitions, questions answered in natural language, lists, comparisons and tables all work particularly well. In fact, the table you read above is there for exactly that reason: it is the format an AI engine cites most readily, because the information arrives already ordered and does not have to be interpreted.

Something that is not content also weighs heavily: consistency. If your website says you are an agency in Madrid, your Google Business profile says something else and your directory profile says a third thing, the model does not know which to believe and, in doubt, names someone else.

Where they are more alike than people think

Here is the most widespread misunderstanding: many people present GEO as a new discipline that makes SEO obsolete, and it does not.

Generative engines rely largely on the same information search engines already index. They need to find your site, to read it without obstacles, to understand its structure and to identify what each page is about. All of that is, literally, technical SEO work.

That is why a site built properly for SEO starts with an advantage in GEO, for five very concrete reasons:

• It is already accessible and crawlable: the systems that feed the models can reach it.
• It already has a clear semantic structure: hierarchical headings that say what each block is about.
• It already loads fast and works on mobile, so nothing blocks it from being read.
• It usually already has structured data — invisible tags that explain to the machine what each thing is: a business, an address, a service, a question.
• It has already built a reputation: other sites link to it and cite it, and that footprint across the internet is what the model has read.

The difference is not in the foundations, it is in the finish. GEO adds a layer on top: rewriting so each answer stands alone, answering real questions in the language people use to ask them, and making sure what is said about you off your site matches what you say on it.

Do I have to choose?

No. SEO and GEO are neither mutually exclusive nor substitutes, and choosing one at the expense of the other is a mistake in both directions.

If you only do SEO, you keep competing for a list of links that more and more users see after having read an AI summary. If you only do GEO with no technical foundation, you are trying to get cited from a website the engine can barely read.

The sensible approach is to treat them as two uses of the same underlying work. Most of the effort serves both; what is specific to each is a thin layer on top.

Where do I start?

In the logical order, which happens to be the cheapest one too:

1. Foundations first. Make sure your site loads fast, looks right on a phone, is crawlable and has an orderly heading structure. Without this, neither one works.
2. Then external consistency. Make sure your Google Business profile, your social media and the directories you appear in say exactly what your website says: same name, same address, same services.
3. Then content that answers real questions. The ones your customers ask you on the phone, written as they ask them, answered so each answer makes sense on its own.
4. Finally, measure and correct. In SEO, positions and visits. In GEO, whether you are named and whether what is said about you is accurate.

The next step

The first move is not to hire anything: it is to know where you stand. What shows up today when people search for you on Google, what an AI engine says about you when asked about your sector, and what on your site is holding both of those back.
