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

Webmaster

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.

Mark Prummel

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!
