GEO for professional services: get your expertise cited by ChatGPT and Gemini

As a professional services provider, you don’t sell a product you can show, you sell trust in your expertise. And today that trust is shaped in part by AI. When a potential client asks ChatGPT or Gemini “who can help me with X” or “what is the best approach for Y”, the answer decides which advisers even make it onto the radar at all. GEO, generative engine optimization, makes sure your expertise is one of the sources the AI cites. In this article you’ll read why GEO matters specifically for consultants and advisory firms, how an AI decides who it cites, and what you concretely do to make your thought leadership citable.

Why does GEO matter specifically for professional services?

For a services provider, reputation is not a marketing layer on top of the product, reputation is the product. Your client can’t try out your work in advance, so they base their choice on credibility signals: published insights, speaking roles, mentions by others and how often your name keeps coming up around a topic. Those are exactly the signals an AI model also uses to decide who it presents as an expert.

On top of that, your client’s orientation phase is largely invisible. A board member weighing up a transformation, or a CFO looking for a new partner, rarely starts with a request for a quote. They ask questions first, and increasingly they ask an AI model rather than Google. If you’re not among the names the model mentions, you simply aren’t considered in that decisive phase. No shortlist, no introduction, no engagement.

The good thing about this market is that the number of searches is lower than in consumer markets, but the value per engagement far higher. A single mention that leads the right decision-maker to you can be worth a multi-year advisory engagement. That makes every missed AI mention costlier than in a high-volume, low-margin market. For the broader logic behind all of this, our guide on what GEO exactly is is a good starting point, and if you work in a broader B2B context, GEO for B2B fits nicely alongside it.

How does an AI decide which expert it cites?

An AI model doesn’t cite the loudest voice, but the source it can recognise, understand and trust. When ChatGPT or Gemini answer a current question, they often pull in live sources through search technology and point to the pages that best support the answer. Gemini leans heavily on grounding via search results, and ChatGPT cites sources when it uses browsing or search. So the question isn’t only whether you have good content, but whether the model can find that content and tie it to you.

Three things weigh heavily here for a services provider:

• Recognisability of the author. The model has to grasp that a particular insight comes from your organisation or a specific expert. The more consistently your name, role and specialism recur everywhere, the easier that is. We worked this principle out in entity consistency and AI visibility.
• Confirmation by others. A model trusts an expert sooner when independent sources also mention that name. For services providers, brand mentions therefore often weigh more heavily than classic backlinks, something we discuss separately in brand mentions over backlinks.
• Verifiability of the claim. AI values insights that can be checked. Concrete, well-supported statements are picked up sooner than vague promises. How a model decides what it considers true, we explain in grounding: how AI decides what is true.

The common thread: AI rewards demonstrable expertise, not self-declared expertise. That’s good news for every services provider who genuinely has something to say and has shared too little of it so far.

How do you make your expertise citable for ChatGPT and Gemini?

You make your expertise citable by cutting it loose from your head and capturing it in clear, findable content with an identifiable author. Many advisory firms only carry their best insights out verbally, in client conversations or on stage. An AI model can’t do anything with that. What isn’t readable on the web doesn’t exist to the AI.

So start with your recurring client questions. Which questions do you get in every first conversation? Which misconceptions do you have to correct every time? Write thorough, honest answers to them, phrased the way someone would actually ask the question. That matches how people prompt and makes your content easy to extract for a model.

Then explicitly tie those insights to an author. State who wrote the piece, with what experience and from which organisation. A name with a demonstrable track record gives a model something to hold on to when citing you as a source rather than an anonymous page. Also make sure the facts about your firm, specialism, sector and region are the same everywhere: on your site, your profiles and in external mentions. Contradictory information makes a model uncertain, and an uncertain model would rather not cite you.

Finally, pay attention to phrasing. Open every page with a short, complete answer to the central question, then build it out afterwards. Use headings that ask your client’s question. Make your claims concrete and traceable. That way you hand the model, literally, the sentence it can take over. If you want to know how this plays out specifically in the biggest assistant, getting found in ChatGPT will help you further.

Which content lets AI pick up your thought leadership?

The content that works best for services providers is the content you should have been making anyway: your real points of view, sharp and well-supported. AI models pick up original insights sooner than rehashed generalities, simply because an outspoken, well-substantiated statement lends itself better to being quoted than a text that says the same thing as ten others.

Think of a clear view on a development in your field, a proprietary methodology you explain step by step, or a level-headed analysis of what does and doesn’t work. Your own data or an honest real-world example make such a piece extra citation-worthy, because it adds something that isn’t anywhere else. Do keep it honest, though: exaggerated claims or promises you can’t back up undermine exactly the trust you depend on, with your client and with the model.

This is also where our own conviction comes from. We’re a Benelux B2B growth marketing agency and one of the pioneers in GEO, and our founder Tanguy De Keyzer wrote the book “The End of Search” because we see buyers’ search behaviour tipping over. That same logic applies to you as a services provider: your insights are your strongest asset, but only if they sit somewhere an AI can find them and attribute them to you.

How do you know if it’s working?

You know GEO is working when the right people get in touch, not when a dashboard counts a mention. Here we hit the core of our approach: visibility isn’t a goal in itself. A citation in Gemini is nice, but only valuable once it moves a qualified decision-maker toward you and that conversation leads to an engagement.

So track two things together. One: are you mentioned on the relevant questions in your field, and in what context? Two: do those mentions also produce conversations with the right profile? A strong mention that lands on a vague page is a missed opportunity. So make sure every page an AI can point to immediately makes clear what you do, for whom, and what the logical next step is. That full picture, from the AI answer to the enquiry on your site, is exactly what our AI search optimization aims at: optimising for engagements and revenue, not for numbers that look good but earn nothing.

The short summary

For professional services providers, AI visibility is an extension of your reputation. Clients orient themselves with ChatGPT and Gemini, and those models cite the expertise they can recognise, confirm and verify. Capture your best insights in clear content, tie them to an identifiable author, keep your data consistent and be honest in your claims. Do that, and you become the name the AI quotes at the moment your next client is still orienting themselves.
