Case studies. From challenge to growth.

A slightly different case study

Anders, the founder of Black Mango, built Sinful's entire Amazon presence from the inside as an employee of the company. That makes this case study a little different: the results were created internally, with direct access to data, systems and decisions from day one — not filtered through an agency lens.

Sinful knew its customer — just not on Amazon

Sinful has strong products, a well-known brand and a loyal customer base in the Nordics. But on Amazon they didn't exist: no revenue, no visibility. Amazon is where a large share of European consumers start when they look for a product, so even as a Nordic market leader, Sinful was invisible to that part of the market. That was the problem to solve.

What we actually did

We started by selecting the products with the best chances rather than listing the whole catalog at once. Each product got its own keyword strategy based on volume and competition. In parallel we improved the listings themselves — copy, images and structure — which lifted the conversion rate by 25 percent. On Amazon that matters a lot, because anything that sells better also ranks better.

We also set up a better inventory system, forecasting demand more accurately and timing shipments so we almost never ran out of stock. When you run out, you lose your ranking — and it's slow to rebuild.

The result

Sinful went from no Amazon revenue to a seven-figure monthly turnover. Several products reached the top 3 on high-volume search terms, the conversion rate rose 25 percent, and stockouts fell by more than 80 percent. The three are directly connected: better listings drive more sales, more sales drive better ranking, and solid inventory management keeps that ranking from slipping away.
