HTTPS: The importance of a secure website

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!

Algemeen Directeur

Onder helps us with our organic search visibility, both via SEO and via GEO. They look at how we can maintain our visibility in search engines using Kitcentrum and, increasingly, in AI-generated answers as well. They have already demonstrated their capabilities during previous changes to our URL structure. We did not lose any rankings and, in fact, saw our visibility improve. That gives us confidence. Now, Onder is helping us prepare for our replatforming. We are fully confident that they will guide us effectively through this transition and manage to retain our organic rankings as much as possible.

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 discuss everything. 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 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!
