"Jij stond boven in AI ook. Ik zocht een partij die zich daar meer mee thuis voelde." Senior specialists on your account, from the very first call
With us, the specialist sits at the table. You discuss your plan with the strategist who draws it up and with the people who build your SEO, campaigns and website.
Your sales team has a say. Together we look at which enquiries are really worth something, and we adjust the channels to match. Every month you see in black and white what it delivers.
We don't steer on clicks or rankings, but on the enquiries that land in your CRM.

Pipeline all year round, not just in the busy season
Suivo, software for fleet and workforce management, got most of its leads from one busy period a year. It wanted a channel that brings in qualified enquiries all year round, in Dutch and French.
Our approach:
- Rewrote the homepage and core pages around the questions buyers ask
- Campaigns in Dutch and French
- Every lead measured through to opportunity
Today 85% of the pipeline comes through the website.
What SEO and GEO did for a B2B website we rebuilt
For a Belgian B2B services company, we rebuilt the website in Astro: fast, lean and made for Google and for AI agents, following every best practice. The result: Core Web Vitals passed with real users, an SEO score of 100, agentic browsing 3/3, and from almost zero to 2,150 clicks and 1 million impressions from 26 March to 24 September 2026. We use the same approach for every client. Read the full case.
A selection of client results:
- +189% MQLs in 6 months for Facilicom
- A 2.5 million euro deal through account-based marketing
- 25% saved on the Google Ads budget for Facilicom
- +400% daily visitors in 66 days for Gom
Core Web Vitals passed (real users, mobile, 28 days) and Lighthouse, website of a Belgian B2B services company
What clients say about working with us
Real Google reviews, alongside what clients told us, shared with their permission.
"The team complements itself perfectly, so you always have someone with very extensive knowledge of specific aspects of marketing, ranging from ads to web design and strategy. The hands-on approach means you can always get started right away, and the feedback is always clear and honest. No nonsense, just facts."
"You have surprised me in multiple ways the last few weeks." "They do not just execute, they also think along strategically. Real B2B specialists. Recommended!"
"Hier worden we met de neus op de feiten gedrukt, en dat is voor ons meer waard dan: tuurlijk, geef mij je geld en we proberen maar iets." "Customer Impact built a strong new website for us and set up a lead generation approach that truly delivers results."
"The report you shared with us was very comprehensive and rich. Really insightful and interesting." Technology was never the real problem.

What companies ask us before they start
What does Customer Impact specialise in?
We are a B2B marketing agency in Antwerp. We help companies win more and better leads with SEO, visibility in AI assistants (GEO), Google, LinkedIn and Meta Ads, content in Dutch, French and English, and websites that turn visitors into enquiries. We steer on qualified leads and pipeline, not on clicks or reach.
What does working with Customer Impact cost?
Every service has fixed price tiers, so your budget is clear upfront. Ongoing work such as SEO or advertising runs monthly, a website is a project. We don't bill by the hour, and for advertising our management fee is separate from your media budget. You'll find the tiers on each service page.
What results can you show?
Facilicom achieved +189% more MQLs in 6 months, with 22% lower monthly ad costs. Suivo cut its cost per lead by 61% in 2025. Gom gained +400% daily visitors through SEO in 66 days. On our results page you will find our cases by service, with the numbers and the time frame.
Can you make us visible in ChatGPT, Gemini and Perplexity?
Yes, that's called GEO. SEO gets you ranking high in Google, GEO gets AI assistants to mention your company and use your pages as a source. We build pages that answer your buyers' questions directly and measure how often you show up in AI answers. The free GEO checker shows where you stand today.
Do I have to buy everything from you, or can I start with just SEO or ads?
You can start with one service and expand later. If you use several channels, one team works with the same audience, the same landing pages and one report. That way you see which channel really brings in leads, without having to align different suppliers yourself.
How do we get started, and how long does a partnership run?
You send us your question and get an answer within 24 hours on working days. In a free call we look at your goals, channels and numbers, and then you get a tailored proposal. A partnership runs for at least 3 months, with no annual contract: that's how long it takes to test, adjust and measure the first results.
Which companies and regions do you work for?
B2B companies in Belgium and the Netherlands, from our base in Antwerp. Our clients include software and SaaS (Suivo, Aikido Security, Kaizo), facility services (Facilicom, Gom), industry (Atlas Copco) and mobility (Get Driven). We work in Dutch, French and English.
What should you look for when choosing a marketing agency?
Ask for cases with a client name, a number and a time frame. Ask how they report: on enquiries and pipeline, or on clicks. And ask who will actually do your work. With us, the strategist and the specialists who build your channels join the conversation themselves, and we say so straight away when we're not the right partner.
