Resumen

  • What is GEO? It is the new SEO adapted to Artificial Intelligence. It seeks for ChatGPT, Perplexity, or Google AI Overviews to mention your brand in their responses.
  • The key? While SEO seeks positions and clicks on Google, GEO aims to be the trusted source for AI. You need both.
  • How is it done? By providing your own data, demonstrating authority, and using structured formats (lists, tables, FAQs) that make it easier for AI to read.
  • Why does it matter today? In the Spanish-speaking market, there is very little competition. If you start optimizing now (with tools like CreceRank), you will dominate AI mentions in your sector before the rest.

Are you looking to understand what GEO is? Where did it come from? And why is it necessary to apply it as soon as possible?

Don’t worry, by the end of this article, you will have it clear.

Remember that the goal of SEO is to appear on the first page of Google.

This changed with the arrival of artificial intelligence.

Now millions of people ask ChatGPT, Perplexity, Gemini, or Google AI Overviews directly before opening a traditional search engine.

And in those answers, you either are or you aren’t.

The GEO (Generative Engine Optimization) is the discipline that helps you appear.

What is Generative Engine Optimization?

GEO is the evolution of SEO in response to artificial intelligence answers. Yes, mainly ChatGPT and Google AI Overview.

The goal is not only for your brand to be visible to AI, but to be cited, referenced, or used as a reliable source by these systems.

To put it directly: while SEO works to get Google to show your page in its results, GEO works to get AI to mention your brand in its answers.

They are different goals, different metrics, and, to a large extent, different tactics.

SEO vs. GEO: Are they different?

AspectSEOGEO
ObjectivePosition a URL on Google.Be cited by AI systems.
Where you appearTraditional SERPs.AI Overviews and generative answers.
What it prioritizesKeywords, backlinks, and ranking.Authority, clarity, and citable content.
How it gains visibilityRanking up.Being mentioned as a source.
ResultLet them find you.Let the AI recommend you.

They are not opposing disciplines, but complementary.

Don’t get it wrong, the GEO needs SEO and we will explain the reason.

Let’s go back to basics. Traditional SEO optimizes for a URL to rank in Google’s search results pages (SERPs).

GEO optimizes for a brand, product, or content to be selected as a source by AI models.

For years, backlinks were the king of ranking factors.

But the story is different with AIs citing you. That is the new authority.

Having Google’s AI Overview cite you can be more relevant than appearing on page 1 for many brands.

There is another important structural change: in traditional SEO, position 1 surpasses position 2 and position 3.

With AI, a brand can be mentioned first in one response and be completely absent in the next about a similar question.

Or be in position 1 on Google and be invisible in ChatGPT.

How GEO works: the fundamental pillars

To appear in the responses of generative models, one must understand how they select their sources.

PillarWhy it matters
Topical authority + E-E-A-TAI prioritizes brands with experience, consistency, and demonstrable credibility.
Structured contentClear answers, lists, tables, and FAQs are easier to cite.
Own and verifiable dataBenchmarks and statistics with sources increase citability.
Multiplatform presenceAppearing in media, directories, and forums reinforces your visibility in AI.

1.Subject authority and E-E-A-T

It’s not enough to have content on a topic: it must be in-depth, consistent, and have clear signals of authorship and credibility.

Frequent updates, original data, citations from recognized sources, and a demonstrable track record in the industry are factors that generative AIs value.

2. Structured content to be cited

From now on, Google wants to reward those who explain better.

The content that AI models prefer to cite has specific characteristics:

Direct answers at the beginning of each section, structured lists, comparative tables, well-written FAQs, and short text blocks that solve problems.

3. Original data and verifiable sources

According to a study by Princeton on GEO (2024), inline citation statistics increase visibility in AI by 37%.

Generating your own data, such as surveys, benchmarks, and analyses of your sector, and citing them explicitly in the content is one of the most effective strategies to become the preferred source for LLMs. 

4. Presence on multiple platforms

Appearing in directories, industry media, specialized forums, and reference articles that models already use as sources significantly increases the chances of being cited. 

And don’t forget about Reddit, one of the main sources of AI. 

What is Share of Voice in AI?

In SEO, we talk about positions and clicks. 

In GEO, the metric that matters is the Share of Voice in AI: what percentage of the relevant responses in your sector mention your brand, compared to the competition.

The essential KPIs that any serious GEO strategy measures are: 

  1. Citation Rate (how often you are cited)
  2. Share of Voice (your share of mentions compared to the total number of referenced brands
  3. Sentiment Score (what AI says about you when it mentions you) 
  4. Source Attribution (from which content it cites you). 

Measuring these metrics requires specific tools designed to track brand presence within generative responses.

CreceRank is precisely that: an AI visibility platform built for Spanish-speaking businesses that want to know exactly how they are mentioned by ChatGPT, Perplexity, Google AI Overviews, and other models.

The GEO opportunity in Spain and LATAM

Most resources on GEO are in English and aimed at English-speaking markets.

In Spain and Latin America, the adoption of these strategies is just beginning, representing a real window of opportunity for companies that act before the competition.

AI models work in Spanish and cover the entire region, but the volume of quality content in Spanish that serves as a source is still low compared to English.

This means that today it is easier to position yourself as a reference in many niches of the Spanish-speaking market than it will be in twelve months.

In summary

The GEO is the new way to position your brand for Google and the most used AIs by your target audience.

It is a discipline that has been paired since its inception with SEO.

That is, you cannot do GEO without SEO. And we dare to say that the same applies to the opposite case.

The good news is that the tools to measure and improve it already exist.

CreceRank was specifically designed for businesses in Spain and Latin America to start working on their visibility in AI today, with data from each country and an interface that does not require technical expertise to use.

FAQs

GEO is the optimization discipline aimed at having your brand, content, or product cited by generative artificial intelligence systems when responding to relevant queries for your sector.
No. They are complementary disciplines. SEO remains the foundation for Google to index and rank your content, which is a prerequisite for AI models to access it as well. GEO adds a layer of specific optimization for generative systems, with its own metrics and tactics.
For that, there are visibility monitoring tools in AI. CreceRank, for example, tracks if your brand appears in the responses of ChatGPT, Perplexity, Google AI Overviews, and other generative engines, and provides you with concrete recommendations to improve your Share of Voice. You can try it for free for 14 days.
Very relevant, and especially strategic now. The volume of quality content in Spanish available as a source for AI models is still low compared to English, which opens a real window of opportunity for Spanish-speaking companies to build thematic authority before the competition does.
