Case DEK installaties.
A website that works. And enquiries that come in.
DEK installaties installs and maintains air conditioning for homes and businesses in the Zoetermeer region. Skilled work, with plenty of knowledge, experience and personal attention.
The old website was a simple WordPress site with a standard contact form. Maintenance wasn't handled well and the form regularly stopped working. That cost customers. On top of that, the form attracted a lot of spam.
The challenge
A form that cost customers.
The website was outdated and too slow. Its image and feel didn't match what DEK wanted to convey. And the enquiries that did come in were often incomplete, so DEK had to call back first to find out whether a visit was worthwhile.
Time to get to work. Time for a stable, professional website.
The approach
A cool plan.
First we sat down to answer one question: what should the website really do? That led to three goals.
Get rid of spam
A form that lets real enquiries through, and keeps spam out.
Fewer call-backs
The right details upfront, so DEK knows straight away whether a visit is worthwhile.
Professional and personal
A look that matches the craftsmanship, without losing the personal touch.

Before and after
Number one in the region.
DEK deliberately works in its own area, in and around Zoetermeer, and wants to be highly visible right there. Relevance then matters not just for Google, but above all for the visitor. DEK now ranks in position one for competitive, high-converting Dutch search terms such as "airco plaatsen" (air con installation) and "airco onderhoud" (air con maintenance) in its own region.
