Before trying to appear in AI, find out where you stand

Many brands are already asking how to appear in ChatGPT. The question that comes first is less eye-catching but much more useful: what does AI understand about your business today?

The audit separates hunches from real problems. Content might be missing. Information might be contradictory. Or competitors may be supported by sources the models find clearer and more reliable.

Surely one of these situations does it look familiar to you

🔸 You ask about businesses in your sector and the same ones always appear. Yours doesn't even say hello.

🔸 On Google you're visible, but don't know whether that presence carries over to ChatGPT, Gemini or Perplexity.

🔸 You want to work on GEO, but first need to know whether the problem lies on your website, in the content or outside it.

🔸 Your team has run its own tests, but every question returns something different and nobody knows what to conclude.

An LLM audit with a method

One isolated answer tells you little. Models change, wording matters and a brand may appear in one query and disappear in the next.

That's why we use a considered set of questions, repeat tests, compare engines and review the sources involved. We then connect our observations with your website, content, entities and external brand signals.

LLM audit or GEO service?

The audit is a fixed-scope project: it measures, compares, diagnoses and prioritises. It shows your starting point and what we would do first.

The SEO for AI or GEO service starts afterwards. It's the ongoing work of implementing improvements, creating content, strengthening authority and measuring progress.

You can commission just the audit. If you later want help implementing the plan, we can stay on too. Without holding the report hostage.

What we may discover

That your brand appears linked to an old service. That ChatGPT cites a directory where your listing is incomplete. That a competitor answers a specific question better. That your website explains the “how” very well but never makes clear who it serves.

We may also discover that publishing twenty articles won't fix the problem. It's a less spectacular conclusion and sometimes the most profitable one.

What are we doing

What we analyse in an LLM audit

We're not looking for an invented score to put on a cover. We want answers: where you appear, who takes your place and which signals explain the difference.

Your visibility in ChatGPT and other AI engines

We test questions a real person might ask before hiring or buying.

We review whether you appear, how often, in what context and how your brand is described. We compare ChatGPT, Gemini and Perplexity because they don't all find or construct answers in the same way.

Who appears when you don't

We identify the businesses, products and alternatives that recur in answers.

We go beyond a list of names. We compare the topics they dominate, how they're presented and which signals seem to help them enter the conversation.

What AI understands about your brand

We check whether models understand who you are, what you do, who you serve and where you work.

We identify outdated information, vague descriptions and contradictions between your website, profiles and external mentions.

Which sources contribute to the answer

We examine visible citations and sources that recur around the topic.

It might be your website, a media outlet, a directory, a listing or a third-party page. Knowing where the answer comes from helps you stop publishing blindly.

Your website through AI's eyes

We check whether the architecture, crawling and content make your business understandable without piecing together a puzzle.

We analyse key pages, internal linking, entities, structured data and answers to real questions. If the problem is technical SEO, we call it technical SEO.

Which opportunities are worth pursuing

We prioritise actions by impact, effort and connection to the business.

Some opportunities need a new page. Others need a corrected explanation, a stronger source or an improvement to what already exists. The report ends with decisions, not a collection of possibilities.

Our method

How we carry out an LLM audit

AI changes quickly. Good research methods don't change as much: a useful question, a reasonable sample, comparison and context before drawing conclusions.

01.

We understand what you sell and who should find you

We define services, markets, customers, competitors and business decisions. A query that can't bring you closer to a real opportunity isn't included just because it sounds interesting.

02.

We turn real searches into questions for AI

We start with customer questions, Search Console queries, pages already receiving traffic and sales team conversations. We use those to build a representative set of prompts rather than a generic battery for any business.

03.

We query the main engines

We run queries in ChatGPT, Gemini, Claude and Perplexity, repeat the most sensitive ones and save answers, mentions and citations. We record the date, engine and wording so the analysis can be reviewed.

04.

We compare your brand with competitors

We measure relative presence, associated topics and recurring competitors. We look at who appears and their role: recommendation, alternative, example or simple mention.

05.

We look for the reasons behind the answer

We cross-reference observations with content, crawling, entities, structured data, authority and external sources. We can't look inside a model's mind, but we can detect patterns and gaps that can be addressed.

06.

We tell you what we'd do first

We organise findings into a roadmap with priorities, estimated effort and suggested owners. The last page doesn't say “keep improving”; it says what to change, why and which signal we'd measure again.

Benefits

What you take away after the audit

AI visibility map

A snapshot of how your brand appears in ChatGPT, Gemini and Perplexity for the questions that matter to your business.

Competitor benchmark

Who appears in answers, for which topics and in what position relative to your business.

Source and mention analysis

Recurring citations, domains and external signals, alongside gaps or inconsistencies worth correcting.

SEO + GEO diagnosis

Crawling, content, structure and entity problems that may make your offer harder for engines to understand.

Content opportunities

Unanswered questions, pages needing greater clarity and topics where your experience can offer a distinctive answer.

Prioritised roadmap

A plan ending with “this is what we'd do now”. Clear priorities so the report doesn't gather dust in a folder.

Are you really going to miss all of this?

Our values

Why carry out your LLM audit with SLUPU?

We measure first, then propose

Before discussing content, mentions or structured data, we check what's really happening. The audit identifies the problem rather than justifying a solution we'd already prepared.

SEO and GEO on the same team

Part of the diagnosis lies in ChatGPT, Gemini or Perplexity. Another part lies in your website's crawling, architecture, content and authority. One team reviews it all, without two conflicting reports.

We also tell you what isn't worthwhile

An action may be possible yet still not deserve time or budget. We'll tell you what to prioritise and what to leave alone. Sometimes the second list saves more money than the first.

The business comes before the acronym

We don't audit to produce an attractive chart. We choose questions related to services, customers and decisions that could generate business. If a query doesn't matter, we don't inflate it to improve the result.

We can stay on afterwards

The audit is delivered in full and your team can implement it. If you need help, we can also put the roadmap into practice through SEO and GEO. No small print and no holding the diagnosis hostage.

First of all, congratulations on two things: From what I've seen, they are very happy with you at Additium 3D. The reports are amazing. I have never seen such thorough reports. Congratulations.

Loli Vico

Administration Dept.

We are thrilled with SLUPU's work. They handled our Digital Kit grant without us having to worry about a thing. They built us a new website and digital catalog, and I love the result. They also manage our SEO and web analytics.

They are very professional and up to date.

Carla is very approachable, she has known how to listen to me, advise me, guide me, and perfectly capture the project I had in my mind.

I am super satisfied and I recommend them.

VADAVO

Arturo and Christian

Founders

We used to handle part of our digital marketing internally, but we needed an agency to support us in the areas we couldn't reach. Slupu started as ad-hoc support and quickly became the fundamental pillar of our entire marketing strategy.

Both Carla and her team stand out for an exceptional level of professionalism, something truly hard to find nowadays. They are fully committed to every project, attending to every detail with a level of rigor and dedication as if it were their own company, which is clearly reflected in the flawless results they achieve.

We have been collaborating with them for many years and hope to continue doing so for many more.

MYA Advisors

Founder

We are very happy with the work you have done on our website, and especially with Carla and Bruno. From the very first moment, we felt very well supported, listening to our ideas and capturing everything in detail. Communication was fluid and they were always willing to resolve our doubts. Thank you for making our website so special!

Crossing paths with SLUPU on my journey, as the new entrepreneur that I am, has been the stroke of luck of my life.

Carla and Alba are professional and charming. They do everything well, easily, and beautifully.

Forever grateful.

Carlos

Founder

We found them almost by chance, since there is a wide range of marketing and advertising agencies in Valencia. We had meetings with 5 or 6 other agencies and, in the end, we chose them because of the impression they gave us. Professionalism, freshness, dynamism, and commitment.

In this life, sometimes appearances are deceiving. This time was not the case. We increased our presence on our social media exponentially and much faster than expected. They also achieved greater visibility for our company through Google, TripAdvisor, and other platforms. The results are palpable, and we are very happy to have decided on them.

In terms of invoicing, I think their value for money is extremely good. Right now their price is very competitive, but over time, and considering the quality of their service, it won't be long before they become a cutting-edge player in the marketing and advertising agency market.

If you are truly looking for an agency and are a bit lost, before looking at others, talk to them. Whatever your company's roadmap and the sector you are in, they will hit the nail on the head to help you grow and meet your goals.

And no, I’m not getting a commission for this review. The kind and sincere words in this text are based on 200%’s satisfaction with his work and 1000%’s satisfaction with his involvement.

I am very happy with the results I have achieved working with SLUPU for my firm. Since we started working together, I have seen an increase in the number of clients, all thanks to the Google advertising campaigns. Carla has been a fundamental pillar throughout the process, always available, attentive, and with a great ability to understand our needs.

Without a doubt, I recommend SLUPU to any company looking for concrete results and a marketing agency that is committed to its client.

William

Founder

We met SLUPU thanks to the Chamber of Valencia, and we couldn't be happier with their recommendation.

From the very first moment, the work of Carla, Bruno, and Alba has been impeccable, both regarding the redesign they carried out on our website, giving it the professional touch we were looking for, and in all the digital marketing.

Following experiences with other agencies that were not entirely positive, we have been working with SLUPU for several months now, seeing constant growth in both our SEO positioning and the quality of the leads coming in through SEM campaigns. As a small company, we told SLUPU from the very beginning that we wanted a few high-quality contacts, and their work is giving us just that.

It is lucky to have found someone so attentive and personal, which is what every company looks for!

Any questions?

Frequently asked questions about LLM audits

How long does an LLM audit take?

It depends on the number of services, markets, competitors and questions to compare. Before starting, we define the scope and give you a fixed timescale. We'd rather choose a useful sample than promise a huge audit that doesn't help you decide anything.

Can you implement the improvements afterwards?

Yes. We can help with technical SEO, content, authority and an ongoing GEO strategy. You can also implement the roadmap with your own team or another provider: the audit is delivered in full and doesn't depend on hiring a follow-on service.

What's the difference between an LLM audit and a GEO service?

An LLM audit is a one-off diagnosis with a prioritised roadmap. GEO, or SEO for AI, is ongoing work to implement improvements, create or adjust content, strengthen authority and measure progress again. You can commission the audit without hiring us to implement it afterwards.

What do I need to provide to get started?

We need a short meeting, your main URLs, an initial list of services, markets and competitors and, if available, read-only access to Search Console and Analytics. Questions received by your sales team also help; they're often better than a keyword list taken out of context.

What do I receive when the audit is complete?

You receive an AI visibility map, competitor benchmark, source and mention analysis, SEO and GEO diagnosis, content opportunities and a prioritised roadmap. We present the findings so you can ask questions and decide on next steps.

Does an LLM audit guarantee that ChatGPT will recommend my business?

No. No audit can guarantee a recommendation or a fixed position in a generative answer. It can show how your brand appears today, identify gaps and prioritise actions that improve the signals systems can find and understand.

What's the difference between an LLM audit and an SEO audit?

An SEO audit focuses on search visibility: crawling, indexing, architecture, content, authority and organic performance. An LLM audit includes that foundation but also studies generative answers, mentions, competitors, cited sources and how the brand entity is interpreted.

What is an LLM audit?

An LLM audit analyses a brand's visibility and representation in language models and generative engines such as ChatGPT, Gemini or Perplexity. It reviews when the brand appears, what is said about it, which competitors are recommended, which sources contribute and which improvements to prioritise.

What does an AI visibility audit analyse?

It analyses a set of questions related to your services, customers and purchasing decisions. It also compares competitors, mentions, citations, content, entities, structured data and your website's technical foundations to understand what may help or limit your presence.

Which tools are used for the audit?

We mainly work with ChatGPT, Gemini, Claude and Perplexity. The selection can expand if your market uses another relevant system. We always specify the engines, versions and dates included because answers can change.
