About
Traffic Builders is a Dutch performance marketing agency based in the World Trade Center in Almere. It was founded in 2001 by Wolter Tjeenk Willink, who is still CEO, and Emerce now lists it as part of the Unbound group. LinkedIn puts it in the 51 to 200 employee band, though it shows 41 linked staff and the agency's own 2025 press release mentions about 50 people. Search is one channel among many: the site sells SEA, social, display, marketplaces, analytics and CRO alongside SEO, content and a generative engine optimization service with a dashboard that tracks how often a brand is mentioned in ChatGPT, Claude and Perplexity answers.
The case library is long and names clients such as Eneco, Mediq, Liander and LeasePlan. Organic search cases include Flinders, LeasePlan Bank and Pon Business Mobility, with traffic and revenue gains, though some pages give no dates. The Global Search Awards 2023 winners page lists the agency with Mediq in the large local PPC category, the 2025 Dutch Search Awards page places it second for best use of data with Eneco, and it appears in the Emerce 100 for 2026.
What is missing: no Clutch profile was found and the G2 page has no reviews, so there is no independent client rating here. There is no public pricing, and the budget band in this record is an estimate from the contact form's options. No named case shows GEO results yet, and most recent awards relate to paid media rather than organic search.
