Zoetermeer Google Partner agency combining SEO, Google Ads and GEO
About Tree Online
Tree Online is an online marketing agency based at Bleiswijkseweg 37 in Zoetermeer, inside the Dutch Innovation Factory building. It was started by Yde van Deutekom and Paul Schout, who met as pupils at Erasmus College in Zoetermeer. Yde covers search advertising, Amazon and analytics, and Paul covers SEO and social media. Five more named specialists work on SEO, GEO, link building, web and e-commerce. The agency has worked across many sectors for more than ten years. It started in 2010 (some listings give 18 years in business) and has about ten staff.
Their service list is grouped around goals: more leads, more sales, more staff, and visibility in AI search. Under SEO they handle technical fixes such as speed, mobile layout, sitemaps and crawl errors, then keyword research, conversion-minded copy and link building. They also optimise for answers in ChatGPT and Gemini, and run Google Ads, Bing Ads, Google Shopping, paid social, remarketing, video and Amazon campaigns. The agency is a Google Partner and uses Whatagraph for reporting dashboards.
The most relevant work for dentists is the Haaglanden Clinics case. Haaglanden Clinics is an independent treatment centre in The Hague for oral and maxillofacial surgery and sleep medicine, set up by HMC's oral surgeons and opened at the end of 2018. Tree Online built its website from a customer-journey analysis, ran SEO and Google Ads for searches such as kaakchirurg den haag and wortelpuntbehandeling den haag, and set up its Facebook and LinkedIn pages. The results were a rise of more than 100% in the first year, a conversion rate above 10% and top-three positions for the main terms. The agency has supported the clinic since opening, and its location manager credits their personal involvement and fast responses.
On Trustoo the agency holds 55 reviews rated excellent. Common themes are proactive thinking, support with international Amazon campaigns, reaching agreed goals and capable SEO help. Other named clients include Solbeach in Scheveningen, Groei & Bloei, the logistics body HIDC and Skatestore.nl.
New clients start with a free growth plan and quote. A kickoff with a dedicated project manager follows, setup usually takes up to a month, and after that there are monthly reports and regular reviews. Some clients start from 500 euros a month, and the enquiry form offers budget bands up to 3,000 euros and above. The hourly rate is 90 euros. They do not ask for long-term contracts. This model fits a single clinic or specialist centre in the Haaglanden region that wants SEO and paid search handled together.
