How to rank on ChatGPT: A guide for industrial SMEs

Your company has spent decades building a reputation in its sector. Your customers know you, trust you, and come back. But there is one question you have probably not asked yourself yet: what does ChatGPT answer when someone asks for a supplier of your type of product or service in your area?

If you have not checked, do it right now. Open ChatGPT and write: “Who are the best suppliers of [your service] in [your city or county]?”. What you find —or do not find— will tell you more about your digital situation than any analytics report.

This is the new reality of industrial B2B marketing in 2026: generative search engines such as ChatGPT, Perplexity, or Microsoft’s AI-powered search engine have become the first filter a purchasing director uses to draw up a shortlist of candidates. And within that filter, most Spanish industrial SMEs are completely invisible.

This article explains why that happens, what it means for your business, and what you can do about it. It is the first in a series of six articles in which the entire system is covered, from diagnosis to a week-by-week action plan.

The behavioral shift nobody has told you about

For two decades, B2B digital marketing has been organized around Google. Appearing on the first page for searches relevant to your sector was —and still is— one of the most profitable investments an industrial company can make. But the ecosystem is experiencing a transformation that, in terms of speed, is unprecedented.

ChatGPT surpassed 900 million weekly active users in 2026. Perplexity is growing at a steady pace. Microsoft’s search engine integrates generative answers into every query. And these models are not just more sophisticated search engines: they are systems that synthesize information, produce answers, and make direct recommendations, with or without a link to an external source.

The difference from Google is critical to understanding the impact on your business. When someone searches Google for “CNC machining supplier Barcelona,” they get a list of ten results and decide which one to visit. When they ask the same question in ChatGPT, they get a direct answer: “Some companies with a strong reputation in this segment are X, Y, and Z.” If your company is not in that answer, it does not exist for that buyer at that moment.

And that moment matters more than it seems. According to Salesforce’s State of Sales report for 2026, 77% of B2B buyers are highly likely to buy from the supplier that was leading their shortlist before the first sales contact. The AI filter happens before your sales team has the chance to speak to anyone.

Key fact: 94% of industrial SMEs in Spain are completely invisible to generative search engines. Not because they are bad companies, but because nobody has yet explained what signals AI needs in order to include them in its answers.

What GEO is and how it differs from SEO

Generative Engine Optimization, known as GEO, is the set of strategies and techniques aimed at improving a company’s visibility within the answers generated by artificial intelligence models. It is, in essence, SEO adapted to the new generative search ecosystem.

The most common confusion is to think that GEO and SEO are the same thing under a different name. They are not. They have different goals, different metrics, and, in part, different mechanisms. Understanding those differences is the first step in knowing where to invest your time and budget.

What SEO and GEO have in common

Both disciplines start from the same premise: you need to be found when someone searches for what you offer. In both cases, quality content, domain authority, and data consistency matter. And in both cases, results take months to fully materialize.

This matters because it means the work you have done in SEO is not wasted from a GEO perspective. A well-structured website, with up-to-date technical content and consistent data across all platforms, is also a solid foundation for AI positioning.

What fundamentally sets them apart

SEO optimizes for ranking algorithms: it wants your page to occupy the top positions in a list of results ordered by relevance. GEO optimizes for language models: it wants AI to include your company in a generated answer that nobody asked to be a list.

In SEO, the success metric is position and click. In GEO, the metric is mention: does AI cite you when someone asks about your sector? How often? With what description? In what context?

The signals each system weighs are also different. SEO prioritizes backlinks, loading speed, and keyword density. GEO prioritizes the technical depth of content, the consistency of structured data, and verifiable external reputation. They are not contradictory signals, but the emphasis is different.

Why industrial SMEs start at a disadvantage

There is an obvious paradox in the world of Spanish industrial SMEs: they are companies with decades of experience, deep technical knowledge, and a reputation earned in their markets. But that reputation exists mainly in the offline world, in business relationships built over time, in word-of-mouth referrals between purchasing directors who have known each other for years.

The problem is that AI models cannot read offline reputation. They can only process what exists on the internet: published content, structured data, mentions in directories and media outlets, public reviews. And in that digital universe, many of the best industrial companies have a very weak presence.

The typical profile of the industrial company that is invisible to AI

At Smart Team, industrial companies in Catalonia and other regions of Spain have been audited. The pattern repeats itself with variations:

1- A corporate website between five and twelve years old, with a design that was acceptable at the time,
2- No active blog or no new posts published in more than two years.
3- A LinkedIn company profile created but with no activity.
4- A Google Business profile half claimed or not claimed at all.
5- No structured data implemented on the website.
6- Zero presence in the relevant industrial directories.

That company could be the best supplier in its sector within a radius of one hundred kilometers. But for ChatGPT, it does not exist.

The window of opportunity that is closing

The good news is that most direct competitors are in the same situation. The fact that 94% of industrial SMEs in Spain are invisible to AI also means that the first company to work on its AI positioning in its niche and geographic area will have a competitive advantage that will be very difficult to reverse.

AI models learn cumulatively. The authority you build today still carries weight tomorrow. The competitor who starts in 12 months will not simply be able to pay to catch up with you: they will have to build from scratch the same authority that you will already have consolidated.

That window of opportunity exists today. In 12 to 18 months, in the most digitally active industrial segments, there will already be companies that have taken their position. The time to act is now.

The 5 pillars of AI positioning for industrial companies

Throughout this series of articles, each of the five pillars that determine whether an industrial company appears or does not appear in ChatGPT’s answers will be developed in depth. They are introduced briefly here so you have the full map before going deeper into each one.

Pillar 1: Content authority

AI models cite companies that have demonstrated deep knowledge of their sector through published technical content. Not just any content will do: it has to be specific, technical, and substantial. An article on “what anodizing is” written by a company that performs anodizing carries incomparably more weight for AI than ten generic posts about business digitalization.

Pillar 2: Structured data

Schema Markup is the language your website uses to speak directly to bots. Without structured data, the model has to infer who you are, what you do, and for whom. With it, it knows with certainty. The difference in visibility is significant.

Pillar 3: Presence in external sources

AI does not just read your website. It reads everything that exists about you on the internet: industry directories, specialized media, associations, LinkedIn, Google Business. The more high-quality sources speak about you consistently, the stronger the signal the model receives.

Pillar 4: Brand consistency

Contradictory data about your company —different versions of your name, outdated addresses, different phone numbers across platforms— fragments the signal AI receives and reduces its confidence in the information it has about you.

Pillar 5: Reputation and reviews

AI models are conservative when it comes to recommending: they prefer companies with verifiable reputation. Google reviews, media mentions, and references in industry associations are trust signals that AI actively weighs.
