Zaanstreek SEO, Google Ads and web design agency with a local dental client
About SEO vrienden
SEO vrienden (SEO Vrienden B.V.) is a small search marketing agency at Bruynvisweg 18 in Wormer, in the Zaanstreek area north of Amsterdam. The team started in 2019 out of an international webshop, and that background still shapes how it measures work: in orders, enquiries and bookings rather than traffic alone. Owner Jesse Haanstra is an SEA specialist. The other named staff are Jelle Duijf (SEA), Mike Reurings (SEO), and Daniel Klijn and Jay van der Meij (web design). The team has eight people.
The agency offers SEO, online advertising and web design, plus domain registration, SEO hosting and monthly website maintenance. Its SEO work covers keyword research, technical fixes, content and authority building, with monthly reports. New clients can request a free site scan, called the 'Vriendendienst', that lists the first three things the team would fix, with results emailed within two working days. Before making promises, the agency takes a baseline measurement. Its town pages show a local focus. The Zaandam page, for example, explains why it treats 'Zaandam' and 'Zaanstad' searches separately and advises a separate page for each.
For dentists, the most relevant evidence is KT3 Tandartsen in Zaandam. KT3 Tandartsenpraktijk is among the agency's completed projects, and SEO vrienden wrote the practice's blog content, including a post on fear of the dentist. KT3 also runs town pages for Wormer, Wormerveer and Wormerland and treatment pages such as teeth whitening, the kind of local structure the agency recommends. This suits single-site practices in the Zaanstreek and wider North Holland that want hands-on local SEO and Google Ads from a small team.
Other published results are outside healthcare. For Dartshop Zaanstad, average Google position improved from 15 to 9 within a year, 41% of tracked keywords reached the top five, and a branded campaign hit a ROAS of 16.49. Hendriks Housing got six times more appearances in AI answers between May and August 2026, based on Search Console data.
Reviewers rate the agency 4.9 on Google from about 55 reviews, and Trustoo shows 64 reviews across three sources. Common themes are professional and reliable service, staff who think along with the client, clear communication and personal guidance. One reviewer mentions weekly meetings during a project. SEO vrienden is a Google Partner.
SEO vrienden does not publish euro prices. SEO starts from four hours a month, pricing is agreed upfront, and no annual contract is required.
