SEO audit

Felix Noordberger

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.

The SEO world is full of self-appointed gurus. Some know better than others. Not infrequently, they crack each other down and sell new services or sites. So the key is to find a good supplier... In this search, Martijn was referred by another company. Martijn is a breath of fresh air in this world. Modest, a thinker, finally a consultant who does not make empty promises. The whole process takes time, money and patience. After several months, there were sufficient results. We are happy to recommend Martijn to companies, who want serious onder support in their SEO policy.

Very good, huge amount of handles and explanations with that included!

Content marketeer

Onder helped us organise the course choice information on our website in such a way that it better aligns with the search behaviour of our target groups and is easier to find in search engines. Working with Ineke, Jelle and Martijn was a pleasure; they were committed and professional. It really felt as though we were all working towards a single goal. The result is content that is not only easier to find and more relevant, but which we can also use widely across our communications.

"Working with Jeroen and the Onder team felt like a true partnership. Jeroen provided both strategic and hands-on leadership during the website transition, seamlessly aligning the technical and SEO strategy with our web development agency. If you want a SEO partner who delivers clarity, collaboration and measurable results, Onder is the one to trust."

I’ve been working with Onder for about a year now, and I really should have done so much sooner. I thought I could manage everything myself with SEO, and that went quite well, but since I’ve been working with Onder, my website’s search visibility and conversion rates have increased dramatically. Jan Willem is a true professional who really gets to grips with your business and therefore knows exactly what works. On top of that, I simply have a great deal of confidence in Onder. I’ve had some very bad experiences with other online marketing companies, which is why I actually wanted to keep doing everything myself. I’m glad I decided to outsource my SEO after all. It’s better for my business and it also gives me peace of mind, knowing that my website is in very good hands.
