When you’ve had someone build a website for you, it turns out to be common practice for that “someone”, usually a web developer or a web designer, to add a “design by” or “website developed by” footer link to your site. Let me make my point clearly: if they haven’t given you a discount to […]Read: "“Design by” footer links…"
I am an internet entrepreneur with a background as an SEO, digital marketer, and web developer. In the early days of my career, I worked in several IT companies, ranging from enterprise hosting to online marketing agencies. This allowed me to work with several large brands around the world.
In 2010 I founded Yoast, which has as its mission to allow as many people as possible to build a findable website. It empowers people through software (most notably its Yoast SEO plugin) and training. Team Yoast currently consists of more than 150 people. Yoast SEO is currently available for four open-source platforms and active on more than 12.5 million websites.
In 2021 we sold Yoast to Newfold Digital and after a short transition period I took a step back, which means I’m currently active as an advisor. My wife Marieke, Yoast’s former CEO, is currently its Head of Strategy and is still at Yoast on a daily basis. She and I have invested in several companies. I act as an advisor for some of the companies we have invested in. More about our investments can be found on the website of our investment vehicle Altha.
I’m 40 years old and live with my wife Marieke in Wijchen, near Nijmegen, where Yoast also has its main offices. We have four kids: Tycho, Wende, Ravi & Borre, who are between 7 and 16 years old.
Outside of work I enjoy reading, LEGOs and playing board games with my kids.
Every once in a while I get an email about W3C validation. The people emailing me either point me at the fact that my own site doesn’t validate correctly (thank Facebook for most of that), or they ask me whether I think W3C Validation is important. Most of them ask even more specifically: whether I […]Read: "W3C Validation: Why you should care (and why not)"
I’ve been working on a secret (side) project for 3-4 months now, way longer than I ever intended to work on it, but it’s now ready for release.

For a small project, I had to create a smart mailto link to make my life a bit easier. I wanted the mailto link to hold not only a to and the subject (I’d figured that much out) but a multi-lined body too. Turns out that is pretty darn easy to do. So, for my […]Read: "The Full mailto Link Syntax"

As regular readers of this blog might know I have written quite some tools using the different API’s of search engines, and always found them quite useful. When I was implementing my sitewide search function, one of the things that bothered me that it was a bit slow. I knew that I had seen some […]Read: "PHP-APC: Speed up your web applications!"

I’m doing some work on a site which has like 4,500 pages indexed with a PHPSESSID in the URL, causing some major duplicate content problems. I got the server admin to disable the PHPSESSID’s by adding the following to the vhost config: I also wanted Google to get a clean URL when it decided to […]Read: "PHPSESSID in your URL?

I got an email from Mozilla’s director of product management Sherman Dickman today, that my sortable table script wasn’t sorting numbers above 1 million which have comma’s in them correctly (they do have a lot of Firefox downloads ;) ). The problem was caused by the fact that replace only replaced items once, where they […]Read: "Sortable table script updated to v1.5.5"

The demise of the project could easily be the demise of your project and the project’s growth could lead to your business growing immensely. The larger your business becomes and the bigger the impact of your company on the project, the more this is true. Economically this is a very unusual situation.
