Amazon & Bol.com Case Studies | Hans van Leeuwen
Documented marketplace results by Hans van Leeuwen: Amazon NL/DE, Bol.com and e-commerce operations case studies, including Connect Car Parts and Alpine.
This portfolio brings together hands-on marketplace and e-commerce work by Hans van Leeuwen, e-commerce & marketplace manager based in Amersfoort. The case studies focus on the operational work behind growth: product data, marketplace listings, advertising, stock planning, reporting and automation across Amazon, Bol.com, eBay and own webstores. Every case shows the starting point, the intervention and the measurable commercial or operational result.
The featured Connect Car Parts case describes a Dutch automotive parts operation selling A.B.S. brake parts through Magento, Amazon DE and eBay DE, with catalogue quality, vehicle fitment data, Channable feed management, listing optimisation, advertising and recurring performance reviews. Other documented results: 70% market share in an Amazon NL earplug category (Nielsen 2023), out-of-stock below 2% after improving demand forecasting, and 20% more weekly sales from a targeted social ad campaign, all at Alpine Hearing Protection. On Bol.com the same brand moved from vendor to seller after a per-product-group calculation, documented in the article 'Vendor or seller on Bol.com: how I ran the numbers at Alpine'.
