Sound familiar?
Our Google traffic is dropping and I don't know why.
We're not on page one for the keywords that matter to us.
We get too few leads from our website, while the competition keeps growing.
How we help
We start with a thorough SEO audit, find the real cause, and build a strategy that lifts you back up in Google and delivers more leads.
Why Customer Impact
We optimize for keywords that bring in customers, not for positions that only look good in a report.
Speed, structure and indexation in order, because without a healthy foundation, content and link building never pay off in full.
We write for search intent and for the visitor, so traffic actually turns into enquiries.
We extend your visibility into AI answers (GEO), so you stay visible as search behavior changes.

Our SEO methodology was built for ambitious companies like yours. We connect marketing and sales, so SEO doesn’t stop at rankings and traffic, but leads to enquiries and revenue. A high position that doesn’t bring in customers is not a result in our book.
A good SEO partner makes sure the right people find you at the moment they’re looking for a solution. Not through tricks, but by keeping your site technically healthy, creating content that matches real search questions, and building authority Google trusts. Where a generalist makes isolated tweaks, a specialist works from a strategy in which every change serves one goal: more qualified traffic that converts. Whether you search for an SEO specialist, SEO consultant, SEO expert or SEO agency in Belgium: the essence is the same. You’re not buying reports full of vanity metrics, but a measurable approach that turns search engine optimization into a lead channel.
We make sure your website is easy to index and find. Think crawlability, page speed, mobile rendering, structured data and solving JavaScript rendering issues. Technology is the foundation: without it, no content effort pays off in full. Most companies underestimate the impact of page speed on SEO and conversion rates.
We build pages around the intent behind a search, not around isolated keywords. That means the right structure, strong internal links and content that fully answers the searcher’s question. For complex sales journeys this requires its own approach, which we’ve developed in our vision on B2B SEO. Increasingly, that visibility is also about appearing in the answers of ChatGPT and Google AI, not just the blue link.
You don’t build trust by buying links, but by earning quality mentions from relevant websites. Through digital PR we earn backlinks that genuinely strengthen your domain authority and keep paying off.
We tie every intervention to data from Google Search Console, analytics and dashboards. So you see not just whether you’re climbing, but whether that climb delivers leads. On high-value pages we test iteratively, following the growth marketing methodology.
Doing SEO yourself is possible, but it costs time and demands broad expertise: technology, content, authority and analysis all at once. A freelancer is strong in one sub-domain, but rarely in all of them. A specialist or agency bundles those disciplines and keeps the strategy consistent. The right choice depends on your ambition and internal capacity. If you want to outsource SEO without losing control, we work transparently: you see what we do, why, and what it delivers.
SEO works at three speeds. Long, specific questions and AI Overviews often move within days to weeks. Broad head terms and enquiries take longer: the biggest gains typically appear between month 6 and 12, and keep compounding after that. Unlike ads, the results don’t stop the moment your budget does. We’re upfront about this, because false promises of quick number-one positions mostly cost you money.
Our approach fits ambitious companies that see SEO as a growth channel, not a cost line, and that want to steer on leads and revenue. And because traffic only counts when it converts, we align SEO with your content and conversion rate optimization.
The fastest way to find out where your growth is hiding is a thorough SEO audit. We find the real cause of your backlog and build a strategy that lifts you back up in Google and delivers more leads. Contact us and we’ll look at your situation together.
Good SEO isn't about tricks, it's about technology, content and authority that fit together. A high position that doesn't bring in customers isn't a result in my book, which is why we always steer on leads and revenue instead of rankings alone.

Case studies
Gom Nederland wanted more organic visibility and to depend less on paid ads. We worked on keyword research, on-page, technology, link building and content. Within 66 days daily visitors rose by 400%, the costs for paid advertising fell by 12% and the number of keywords Gom is found on doubled.
Read the caseWe applied our approach to the website we rebuilt for a Belgian B2B services company and built out a large knowledge base. According to Google Search Console, that site went from almost 0 to 2,150 clicks and 1 million impressions in 6 months, from 26 March to 24 September 2026. To be honest: we don't yet measure leads from that growth separately.
Adventure Valley Durbuy attracted visitors, but on mobile too many people dropped off before booking. We fixed the technical SEO and simplified the mobile checkout process with fewer steps. The mobile conversion rate from first click to purchase rose by 300%.

SEO works at three speeds. Long, specific questions and AI Overviews often move within days to weeks. Broad head terms and enquiries take longer: the biggest gains typically appear between month 6 and 12, and keep compounding after that.
We don't optimize for rankings as such, but for leads and revenue. Every intervention is tied to measurable business goals through the growth marketing methodology.
Pricing depends on scope: your market, the competition and your ambition. Every programme includes the full SEO lifecycle: strategy and keyword research, technical SEO, content, link building, GEO (AI visibility), reporting on leads and continuous refreshing. Contact us for a tailored proposal. We tie the investment to leads and revenue, not to loose hours, so you always know what SEO delivers instead of only what it costs.
Doing it yourself is possible if you have the time and the broad expertise in-house. If either is missing, outsourcing to a specialist usually delivers faster and more durable results, because technology, content and authority are tackled together.
A specialist is your subject-matter expert; an agency bundles multiple specialists and disciplines. At Customer Impact you get both: specialist depth with the firepower of a team.
