Our services, organised by stage
Every service belongs to a stage of the Growth System. That way you see straight away which problem it solves and where it sits in your enquiry flow.





100+ businesses and growing
























This is how one search becomes a signed job.
Follow one enquiry from the first search to the signature. We handle every step, and measure what happens along the way.
Someone types what they need. No idea yet who will do it.
At the top via Google Ads, in the regular results via SEO, or on the map. Three routes, side by side.
Google AdsSEOBusiness ProfileA page that matches what they searched for. Projects from nearby, reviews, one clear button.
WebsiteConversion optimisationThe enquiry comes in and is picked up fast. Whoever calls first has the best chance.
Lead follow-upThe quote is signed. And you know which search it started with.
Fixed price up front. Installed within one day.

Underneath it all: measuring and adjusting. You see what each channel delivers, and every month the budget goes to what works.
Conversion trackingThe Growth SystemExample of one enquiry. Times and names for illustration.
Marketingkenners delivers five services that together form one Growth System: insight, traffic, conversion, follow-up and steering. Your website, Google Ads, SEO, Google Business Profile and lead follow-up work together in it, and we measure every enquiry through to the signed quote. We only work for trade businesses, with one business per trade per region, in the Netherlands and Belgium.
Services that interlock
You cannot buy a separate campaign from us that nobody measures. Every service below is part of the Growth System, with five stages: Insight, Traffic, Conversion, Follow-up and Steering.
There is a practical reason for that. Google Ads works better if your website converts, your website delivers more if the follow-up is right, and everything only becomes steerable once we measure through to the quote. By doing it as one whole, nobody can point at someone else.
If part of it is already in good shape for you, we build on that. In the intro call we look together at which stage delivers the most for you.

Every service, in its place in the system

Frequently asked questions
Don't see your question here? Call, WhatsApp or email us. You'll get an answer within one working day.

Can I also take just one service?
We work from the Growth System, because separate parts need each other to deliver. If part of it is already in good shape for you, we build on that. In the intro call we decide together which services you really need.
Why do you not promise a number of enquiries up front?
Because that depends on your market, your region and your budget. A fixed number without knowing those is a guess. In the baseline we work out how many people in your area search for your services and roughly what an enquiry costs. That way you know up front what you can count on.
Which service should I start with?
In 9 out of 10 cases it starts with your website and the measurement. Only when visitors actually make an enquiry and we can see that does it make sense to buy more traffic.
What kind of businesses are your services meant for?
For SMEs in construction and engineering with jobs from around €2,000, such as roofers, contractors, installers and businesses in prefab and modular construction. For web shops and businesses with small order values we are not the right partner.
Do you do everything yourselves or do you outsource work?
We work with a fixed team of 8+ specialists from Arnhem, for design, development, SEO, Google Ads, hosting and automations. You speak to the people who actually do the work.
How do I measure what the services deliver?
In the first week we set up conversion tracking through to the signed quote. In the monthly meeting you see per channel how many enquiries and jobs it delivered.
