    Bio

    Hi!

    Until May 2025, I’ve led the development team called Lingo at Yoast, which focuses on the content analysis in Yoast SEO. We specialize in giving you suggestions to optimize your page content (your “on-page SEO”), helping you to potentially rank higher on search engine result pages. On Yoast Contributor Days, you would find me contributing to Core.

    In June 2025, I started working at Infi.

    WordPress Origin Story

    I started out creating WordPress websites in 2008 and absolutely loved the famous 5-minute installation and easy-to-use interface, handily beating my self-written HTML. After a lot of forays I ended up with Yoast in 2021. In June 2025, I started working at Infi.
