GEO. The new battleground of digital marketing.

Users no longer only search Google. They search ChatGPT, Perplexity, Google AI Overview, Gemini. The answers they receive aren't link lists — they're syntheses. If your brand doesn't appear in those syntheses, it doesn't exist for that user.

What is GEO

Generative Engine Optimization

GEO is the practice of optimising content, structure and brand authority so that language models cite you as a relevant source. Unlike traditional SEO, the goal isn't to rank a URL in a list of results. It's to get ChatGPT, Perplexity or Google AI to mention your brand in their synthetic responses.

SEO positions pages. GEO positions concepts, entities and answers.

ChatGPT, Perplexity, Google AI Overviews, Gemini and Bing Copilot already generate millions of daily answers in 2026.

The window is closing. Whoever positions now, stays.

Language models build their authority map from sources that already exist in their corpus. If your brand isn't there, the model won't cite you — not because it ignores you, but because it doesn't know you.

The parallel with SEO in 2004 is precise: companies that bet on organic positioning when no one understood it dominated their categories for a decade. GEO is at that same moment.

In Spain, only a handful of agencies have a structured GEO practice. Most mention it. No one executes it with consistent methodology.

Methodology

Our GEO methodology

Generative presence audit

We analyse how your brand appears — or doesn't — in the leading AI engines. We identify gaps, attribution errors and citation opportunities.

Entity and content strategy

We build the concept map that LLMs must associate with your brand. We write or restructure content to be citable: clear, structured, data-backed, authoritative.

Distribution and authority signals

We publish and amplify in the sources models prioritise: sector publications, reference directories, specialist media.

Measurement and tracking

We track appearances in generative responses, model-by-model variation and brand presence evolution in AI Search over time.

Which companies need GEO now?

—Brands competing in high-query categories: financial services, health, legal, technology.
—Companies already investing in SEO that want to get ahead of the next cycle.
—SMEs that want to build category authority without a large-brand budget.
—Firms launching new products that want models to recognise them from day one.

Why Providentia

—We are among the first consultancies in Spain with a structured GEO practice — not a service bolted on at the last minute.
—We combine GEO with SEO and data analytics because brand presence in 2026 is not built from a single channel.
—We work with a select number of clients. That lets us go deep on every project.

If you want to know how your brand appears today in the leading AI models — and what can be done about it — start here.

Frequently asked questions about GEO

What is GEO or Generative Engine Optimization?

GEO is the discipline of optimising a brand's presence in AI-based search engines such as ChatGPT, Perplexity or Google AI Overviews. Unlike traditional SEO, the goal is not to rank a URL but to get language models to cite your brand as an authoritative source in its category.

How is GEO different from SEO?

SEO optimises for algorithms that rank web pages. GEO optimises for language models that synthesise answers. They are complementary: good SEO builds the authority base that GEO needs, but LLM-specific citation tactics require an additional layer of work.

How long does GEO take to show results?

First observable results can appear in 4-8 weeks for niche queries. Building consistent presence in competitive categories takes 3-6 months, similar to organic SEO.

Does GEO work for SMEs?

Yes, especially. SMEs that build category authority in AI Search now will have a lasting advantage over competitors who arrive later. The entry cost is lower than in competitive SEO because the market is not yet saturated.
