What marketplaces does Hans van Leeuwen specialize in?

Hans specializes in Amazon and Bol.com marketplace management, including product listing optimization, advertising (Amazon Ads, Bol Ads), A+ content creation, catalog management, and growth strategy.

What e-commerce services does Hans offer?

Hans provides marketplace management, conversion rate optimization (CRO), UX design for e-commerce, SEO & content strategy, data-driven analytics, and digital commerce consulting for brands across the Netherlands and EU.

Is Hans van Leeuwen available for freelance or contract work?

Hans is based in Amersfoort, Netherlands and available for e-commerce management roles, consulting, and freelance marketplace projects. Contact via LinkedIn or email for availability.

What does a freelance e-commerce manager cost?

Engagements are priced per model: retainer for ongoing Amazon and Bol.com management, project pricing for defined scopes such as an audit or launch, and a daily rate for interim work. Actual numbers depend on scope and channel mix; a 30-minute intake typically produces a written quote within one working day.

How long until I see results on Amazon NL or Bol.com?

Listing and A+ content fixes tend to shift conversion within 2-4 weeks. Sponsored Products and Bol Ads restructures usually show meaningful ACOS improvement within one advertising cycle (4-6 weeks). Structural share and stockout improvements are a 3-6 month arc because they depend on catalog quality, ad efficiency and forecasting compounding.

Does Hans work on Amazon DE and Amazon FR as well?

Yes. In addition to Amazon NL and Bol.com, engagements regularly cover Amazon DE and Amazon FR for brands expanding across the EU. The setup uses the same operating model per marketplace: listing quality, advertising, pricing, catalog and reporting. Cross-border logistics and VAT are coordinated with the brand's existing partners (for example Staxxer for German VAT).
