Professional Peers and SEO Pioneers: Joost de Valk and Jason Barnard
Joost de Valk and Jason Barnard share more than a decade of professional friendship and collaboration. From Jason consulting on Yoast’s Brand SERP and Knowledge Panel, t…to recording an episode together for Yoast Academy and appearing on each other’s podcasts—Joost on Jason’s podcast (Joost de Valk talks with Jason Barnard about WordPress and Google) and Jason on Joost’s podcast (Jason Barnard, on taking a deep dive into Brand SERPs) they’ve grown from colleagues to trusted peers who shape the future of SEO together through shared insights on schema, site structure, and the Knowledge Graph.
Jason regularly applies Joost’s technical insights—especially advanced features in the Yoast plugin—for his clients’ entity-based SEO, while Joost’s team has cited Jason’s work on Knowledge Panels in the Yoast blog. This mutual respect means Jason confidently builds client strategies on the solid SEO foundations that Joost’s tools provide.
