Trusted by growing brands
Sound familiar?
Our competitors get recommended by ChatGPT and we don't.
Our organic traffic has been dropping since Google AI Overviews.
I have no idea how you even become visible in AI answers.
We don't know what AI is saying about our brand today.
How we help
We first map how AI sees you today, then make your brand understandable to both humans and machines, and build the authority that makes AI models remember and recommend you, exactly where your audience is searching now.
Why Customer Impact
We map how models like ChatGPT present you today, so you know where you stand.
We make your content and structure crystal clear, so both visitors and AI models get you.
We build the sources and citations that make models remember and recommend you.
We measure whether you're mentioned and recommended more often and more accurately, not vanity metrics.
About Customer Impact
Customer Impact is a digital marketing agency founded by Tanguy De Keyzer. For more than 10 years we have been building the growth engine of startups, scale-ups and established companies.
GEO is the new layer under your findability: we make sure AI models remember and recommend you, connected to your broader SEO and growth strategy.
What we stand for:
What we do
We measure whether, how and where AI models mention your brand today, with a baseline across ChatGPT, Gemini, Perplexity and Google AI Overviews.
A concrete plan: which prompts, which entities and which sources we tackle to claim your place in the answer.
We make crystal clear who you are and what you stand for, consistently across your entire presence, so AI recognizes you as one trustworthy entity.
Content AI loves to quote: clear definitions, numbers and answers, backed by structured data (schema).
Mentions on sources AI trusts, such as Reddit, comparison sites and relevant media, because AI builds its picture from the entire web.
We track your brand mentions and share of voice across AI models and adjust based on data, not gut feeling.
Our process
We test how AI models present your brand today and where the gaps are.
We make your content extraction-friendly and clearly structured.
We build the sources and mentions that models rely on.
We track how often and how accurately AI mentions and recommends you.
We refine the approach based on what the measurements show.
More and more buyers no longer start their search on Google, but in an AI chat. They ask ChatGPT, Claude or Perplexity directly for a recommendation, and get one answer with a handful of names in it. If you’re not among them, you don’t exist in that context. As a GEO agency, we make sure your brand does get mentioned, at the moment it counts.
GEO, also called AI search optimization or AI findability, is optimizing your brand and content so AI models correctly understand, remember and recommend you. It’s not about isolated keywords, but about how clearly your brand exists as an entity on the web: who you are, what you stand for and why you’re trustworthy.
GEO doesn’t replace SEO, it builds on it. The big difference is where and how you become visible:
The two reinforce each other: a strong SEO foundation makes you more findable to the crawlers that feed AI, and a strong entity helps you in both worlds.
AI models no longer read isolated pages the way a classic search engine does. They pull information from thousands of sources at once and build a picture of what’s true, what sounds trustworthy and who has expertise. Steering that picture requires a different approach than SEO: entity thinking, digital PR, structured data and continuous monitoring across multiple models. A specialized GEO agency brings those disciplines together, measures what works and systematically builds a head start that’s hard to catch.
Ask ChatGPT, Gemini or Google AI Mode for “the best lawyer in Ghent” or “a good accountant in Antwerp” and you get a short answer with a few names. For many companies the first step towards GEO is the moment they see a competitor there, and not themselves.
That is why we start with a measurement you can check yourself. We ask a fixed set of questions per city and per sector to several AI assistants, note which companies get named and how often, and put that in an overview per model. Every overview comes with a real answer as it appeared on screen, with date and model, so you see what a buyer sees. Then we look for why those names get mentioned: which sources they appear on, which reviews and mentions they have and what their site does differently. That becomes your action plan. How such an answer comes about, read in how to get recommended by ChatGPT.
Google itself says there are no additional technical requirements to appear in AI Overviews or AI Mode: the same foundations as for Search apply. What makes the difference is how clearly, consistently and credibly your brand is described across the web. Want to see where you stand first? Take the free AI visibility checker.
We work from a strategy, not from loose tricks. Our program runs in six steps, from baseline to continuous adjustment.
We measure how AI sees you today: whether and how you’re mentioned, in which models, with what sentiment and where competitors are overtaking you. This is your baseline.
We make crystal clear who you are, what you do and for whom. Consistent information across your entire presence ensures AI recognizes you as one trustworthy entity, not as scattered, contradictory signals.
We build content AI loves to quote: clear definitions, numbers and direct answers, backed by schema and a logical structure that makes your content technically readable for AI.
AI builds its picture from the entire web, not just your own site. Mentions on places like Reddit, comparison sites and relevant media carry serious weight, and most companies still ignore this.
ChatGPT, Gemini, Perplexity, Claude and Copilot each pick their sources differently. We tune your approach to each model, from getting found in ChatGPT to Perplexity and Google AI Overviews.
We track your mentions and share of voice across the AI models and adjust based on data. For that monitoring we use specialized AI visibility tools such as Visibility, tracking your visibility per category and per AI model.
GEO works best for brands whose buyers research before they decide, which is practically every service provider, SaaS company and knowledge-driven business. Smaller, specialized players can actually outrank big names in AI answers, because AI selects on relevance and authority, not on ad budget.
For the liberal professions an AI recommendation is often the start of a first appointment. At the same time, those sectors have their own rules on advertising and communication. We adapt the approach per sector:
For local service providers, AI visibility depends heavily on your Google Business Profile and your reviews. That is what our local SEO service is for.
It’s not hype, it’s a shift that’s already happening. AI search is growing fast and Google increasingly shows an AI Overview above the classic results. That changes how people find information and how traffic gets distributed. Whoever waits until everyone is doing it starts with a handicap.
More and more agencies put “GEO agency” on their site, but approaches differ widely. If you want to choose the best GEO agency for your brand, look for five things:
Measure an agency against this list and you’ll quickly see who’s a real GEO partner and who merely wears the label.
Customer Impact is one of the first agencies in the Benelux to adopt GEO as a separate discipline, and we work as a GEO agency for brands in both Belgium and the Netherlands. Founder Tanguy De Keyzer is regarded as one of the voices shaping the topic in the Benelux. We wrote the book The End of Search, publish one of the deepest knowledge bases on GEO in the region with more than two hundred articles, and built our own FAQ hub and glossary around AI visibility. We also partner with AI visibility tools such as Visibility to measure your visibility rigorously. That knowledge advantage goes straight to work for your brand. Curious about concrete results? Ask us about our GEO cases.
That depends on your starting position, your market and your ambition. We work with a clear scope after the audit, with no surprises afterwards. Contact us for a quote.
The first step is knowing how AI sees you today. We map your AI visibility and build a plan to get you mentioned where your audience is searching now. Contact us and we’ll assess your opportunities together.
GEO isn't hype, it's the new findability. AI models pick one answer, and you want to be in it. Whoever builds a clear entity and citable content today gains a head start that will soon be impossible to catch.

Case studies
YouPower wanted more good B2B requests instead of more requests. In 11 days from first analysis to live knowledge base, 552 pages went live: 184 topics, each in Dutch, French and English. The first request came in on launch day, via Stewie, the AI chatbot on the site.
iBOOD.com wanted to know how AI tools show the brand in the NL, BE, DE and PL markets. We tested 624 questions across ChatGPT, Google Gemini, Perplexity, Claude, Google AI Overview and Google AI Mode, analysed 7,259 AI answers and combined that with 13 months of GA4 data. The result is a GEO audit across four markets and six AI tools.
Creditsafe wanted to understand its AI visibility worldwide at board level. We delivered a GEO analysis and an approach in 90-day sprints, with weekly follow-up for the team and quarterly reporting for the board. We deliberately don't publish client numbers.
In all honesty

GEO is optimizing your brand and content so AI models like ChatGPT, Claude, Gemini and Google AI understand, remember and recommend you in their answers. Where SEO puts you in a list of links, GEO puts you inside the answer itself.
SEO gets you ranked in a list of blue links. GEO gets you mentioned in the AI answer itself, based on meaning, consistency and authority across the entire web. The two reinforce each other: a strong SEO foundation helps your GEO, and vice versa.
By establishing your brand as a clear entity, creating citable content and being present on sources AI trusts (such as Reddit, comparison sites and media). We first map how AI sees you today and build your visibility from there.
The first shifts in your AI visibility are often measurable within weeks, especially on less competitive topics. Building a stable, broad presence takes months, just like SEO. Because competition is still low, building today gives you the fastest head start.
You can't dictate to AI directly, but you can steer it strongly. By placing consistent, correct and citable information across the web, you give AI models the material they base their answers on. That reduces hallucinations and steers sentiment in the right direction.
Yes. Smaller, specialized companies can actually outrank big players in AI answers, because AI selects on relevance and authority, not on ad budget. A sharp niche is an advantage in GEO.
No. We start with an audit and first tackle the pages and sources with the biggest leverage. GEO builds on your existing site and SEO; it's not a full rebuild.
We measure your brand mentions, citations and share of voice per AI model using a fixed prompt set, plus the impact on traffic and leads. So you see in black and white whether you're improving, instead of guessing. For monitoring we use specialized AI visibility tools such as Visibility.
Usually because your competitor is described more clearly and consistently in more places: on its own site, in reviews, in directories, comparisons and media. AI assistants build their answer from those sources. We first show, with a fixed set of questions per city and sector, who gets named today and why, and then work on the sources where you are missing.
