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 100 people. Yoast SEO is currently available for four open-source platforms and active on more than 11 million websites.

Besides Yoast, Marieke and I have invested in several companies. As a result, I also have several advisory roles for companies we have invested in. More about our investments can be found on the website of our investment vehicle Altha.

Private life

I’m 39 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 6 and 14 years old.

Outside of work I enjoy reading, photography and playing board games with my kids.

Optimizing your news site


Joost likes to talk about SEO, Technical SEO, Open Source.

  • SEO for everyone: what does that even mean?

    Open source, Technical SEO

    Joost kickstarted YoastCon 2019 with his own talk about what we feel SEO for everyone means and how we help websites focus on findability, indexability and rankings.

  • The Victory of the Commons

    Open source

    If you’re running a business based on open source software like WordPress, your business depends on the prosperity of that project. 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. Joost will explore what this means and how you should deal with it. This is pure economics; it starts with the well known story of the Tragedy of the Commons but, applied to open source, leads to a completely new outcome. If your business is build on WordPress, you should be here to listen to Joost’s talk and discuss afterwards.

  • WordPress SEO in 2019

    Technical SEO

    Joost describes what’s needed for a site to rank well in 2019 and what you need in order to achieve that. In this talk he will cover the latest updates to SEO as well as some basics.
