New service

Your customers no longer only search on Google.
Now they ask AI.

Do you appear when someone searches for you on ChatGPT, Perplexity or Gemini?

GEO (Generative Engine Optimization) is the discipline that optimises your digital presence so that AI search engines recommend you when a user asks about services like yours. It is the natural complement to traditional SEO in the new era of search.

GEO — AI Search

✓The AI assistant recommends you directly
✓Optimisation for language models (LLMs)
✓Semantic authority, citable content, llms.txt
✓Metrics: AI mentions, generative share of voice

What the GEO service includes

A complete approach so that AI engines know, understand and recommend you.

AI visibility audit

We analyse how ChatGPT, Perplexity, Gemini and Claude mention (or fail to mention) you when someone searches for services like yours. The starting point that defines the strategy.

Content optimisation for LLMs

We rewrite and structure your key content so that language models process, understand and cite it with greater probability. Format, semantic density and authority.

llms.txt implementation

We create and maintain your llms.txt and llms-full.txt files: the emerging standard that tells LLMs what information to index and how to understand your business.

Semantic authority strategy

We build a map of entities and semantic relationships that reinforce your positioning as a reference in your sector before generative AI models.

Citable and structured content

We develop content pieces — statistics, guides, definitions — specifically designed to be cited by AI assistants as reference sources.

Monthly AI mention tracking

We monitor your visibility in the main AI engines, track mentions, compare with competitors and adjust the strategy based on data.

Why GEO is the next major shift in digital acquisition

Traditional SEO optimises your presence to appear on Google. But user behaviour is changing: more and more people search directly on ChatGPT, Perplexity, Claude or Gemini and make decisions based on what these systems respond — without ever reaching Google. If your business does not appear in those responses, you do not exist for that segment of users.

GEO — Generative Engine Optimization — is the discipline that optimises your digital presence so that language models recommend you when a user asks about services like yours. It is not about technical tricks or deceiving AI. It is about making your content sufficiently clear, structured and authoritative for LLMs to consider it a relevant source.

At Mkt Web 360 we were among the first in Spain to develop a structured GEO service. We maintain active llms.txt and llms-full.txt files, optimise content for conversational search intent and monitor brand visibility in the main AI engines on a monthly basis.

The data supports the shift. ChatGPT surpassed 800 million weekly users in 2026. Google AI Overviews already appear in more than 58% of searches. Perplexity processes hundreds of millions of queries per month. 94% of B2B buying groups use generative AI tools before speaking to any supplier. This is not a future trend — it is the current behaviour of your potential customers.

The window of opportunity is narrow. Businesses that build AI authority now will have an accumulated advantage similar to domain authority in SEO: the earlier you start, the greater the advantage. Those who wait will start from scratch in an environment where competitors have already built a presence. In SEO, we know how much it costs to recover lost positions. In GEO, the mechanism is the same.

When does it make sense to invest in GEO?

GEO is not the right solution for every business at every moment. It makes sense when your sector has conversational search volume — when your potential customers ask AI things like "what marketing agency do you recommend" or "what is the best dental clinic in Toledo". If those questions exist, AI answers them with or without you.

It has particular impact in professional services, technology, health, training and digital marketing — sectors where the decision process is long and the customer researches before buying. In these sectors, appearing in ChatGPT's response before the customer reaches Google may be the difference between being evaluated or not existing in the buying process.

For local businesses — clinics, offices, workshops, physical shops — local GEO has an enormous and largely untapped opportunity. When someone asks ChatGPT "what reliable plumber do you recommend in Salamanca", the model tries to give a specific answer. A local business with well-structured content about its area, an optimised Google Business Profile, consistent NAP across all directories and reviews that reinforce local authority can appear in that response before larger competitors.

GEO does not make sense as a sole channel without an SEO base. A technically deficient site without quality content or domain authority has little to offer language models. The correct sequence is: solid technical SEO first, then GEO on top as an additional visibility layer.

How we work on GEO

A structured four-phase process to build and maintain your visibility in AI engines.

AI visibility audit

We check how your brand and services appear in ChatGPT, Perplexity, Gemini and Claude. We identify whether you appear, how often, in what context and what the models say about you or your sector.

LLM content optimisation

We rewrite or expand the content of key pages so that it clearly answers the questions users ask AI assistants. Natural prose, verifiable data, thematic authority.

Technical implementation

We configure llms.txt and llms-full.txt with structured information about your business and services. We implement advanced schema markup and ensure LLM crawlers have correct access to your content.

Monthly tracking

We monitor your brand visibility in the main generative engines. Each month you receive a report on how you appear, what has changed and what actions we are taking to improve.

Local GEO: the opportunity most businesses haven't spotted yet

Most conversations about GEO focus on national or international brands. But the most immediate opportunity lies with local businesses. AI models receive thousands of daily queries with local intent: "best physiotherapist in Bilbao", "tax adviser for freelancers in Zaragoza", "reliable mechanic in Toledo". And they have to respond with something.

The local business that works on its GEO now — with well-structured content about its area, an optimised Google Business Profile, consistent NAP across all directories, and reviews that reinforce its local authority — will be the one that appears in those responses. Local GEO competition is almost non-existent yet. It is the same window that existed in local SEO ten years ago.

At Mkt Web 360 we work on local GEO integrated with our clients' local SEO strategy. They are not two separate projects — they are two layers of the same digital visibility work: one so that Google finds you, the other so that AI recommends you.

Frequently asked questions about GEO

Does GEO replace SEO?

No — they are complementary. SEO remains essential for capturing traffic from Google, which represents the majority of current search volume. GEO adds visibility in the fastest-growing channel: AI assistants. The strongest strategy works both channels simultaneously.

How long does it take to see the impact of GEO?

Technical changes such as llms.txt are implemented within days. The improvement in how frequently AI models mention your brand depends on your content authority and may take between 2 and 4 months to become perceptible. It is a channel under construction — those who start earlier will have an advantage.

How is AI visibility measured?

We make periodic queries to the main LLMs with the questions a potential customer of yours would ask and record whether you appear, how you appear and what is said. It is an evolving methodology because the sector is very new, but it already allows us to detect clear trends and opportunities.

Does GEO work for any sector?

Yes, although the impact varies according to the volume of conversational searches in your sector. Professional services, health, technology, training and digital marketing are the sectors where GEO has the greatest immediate impact. For more local or niche sectors, the opportunity lies in positioning yourself before the competition discovers it.

Technical note

This site already implements llms.txt

Mkt Web 360 is one of the first digital marketing agencies in Spain to implement the llms.txt standard — the file that tells language models how to understand and index a website.

You can view it at mktweb360.com/llms.txt and mktweb360.com/llms-full.txt. We apply to our own website exactly what we offer our clients.
