We are Onder

We are Onder, nice to meet you! A specialist SEO agency in the heart of Zwolle. Our ambition is to one of the best SEO agencies in the Netherlands to become. Too high? Certainly not. Within our team, we constantly put our heads together to perform above expectations and this is a goal we strive for every day.  

In this business, you never stop learning. Whereas Google is getting smarter and smarter at reading texts, we are constantly making strides in onder searching, analysing and optimising websites. Obviously within the SEO field, because that is where our strength lies.

You will join a team with 11 colleagues. These are all specialists who speak the SEO language like no other, supplemented by two colleagues who make sure the process and our own marketing run as smoothly as possible. 

We think it's important not to talk about SEO from time to time, even though we love to do so. This can be during our lunch together, the walk afterwards or our drinks. We have found a good structure for this, so that we can go into the weekend together with some regularity!

Your own personal brand ? the best SEO agency in NL

We want to become the best SEO agency in the Netherlands and believe that the development of our colleagues is as important in this as the results for our clients. That is why we are happy to invest in your own personal branding. Specifically, this means that you:

Renzo van Dongen

Digital content manager Peugeot

Whether it's about content or technical adjustments, it doesn't matter. Martijn briefs this in a very clear way so that it can be implemented locally or by our head office in France. [...] Since the start of our collaboration, we have achieved great results. Keep it up!

Marien van Stegeren

Eigenaar Kitcentrum

When your online onder venture grows, expectations often grow too, in every area. To a large extent, we were in control of SEO and its interpretation ourselves. We found out that our own "general view" was no longer sufficient, so we engaged Bureau Onder. Surprising and clear. We have built up a fine collaboration, partly because Martijn also regularly visits our office with Eline or Mariska (depending on the case), which is very valuable to us!

Marten Stellingwerf


Martijn and Mariska make the SEO story understandable for the layman and are happy to think along with us. It is nice that there is a personal contact moment every month with an extensive report and the opportunity to talk everything through. After just a few months, Onder has already managed to achieve number 1 positions on Google with some of our webshop pages. We are very satisfied with Onder.

SEO Specialist Stella Fietsen

For several years, Onder has been a valued partner of Stella. Martijn is my sparring partner for complex SEO issues and the extra pair of critical eyes that keeps us on our toes. Together, we have achieved nice growth in online visibility, visitor numbers and leads. Onder onder stands out for its short lines of communication and professionalism. They speak our language: don't nag, get down to business. That is what we love!
