Stradivarius CZ entrusted us with its campaigns. €65,593 in revenue in a single quarter.

Stradivarius is one of the key players in fashion e-commerce. The goal of the collaboration was to scale performance in the Czech market. Ninety days. One online store. The Czech market. And results that speak for themselves.

How it started

The collaboration through Tradedoubler launched in October 2025. The first numbers were modest — 1,282 clicks, €881 in revenue. The campaign was gradually collecting data, and we knew the best was yet to come.

What we set up

The strategy shift came with better technical configuration.

Product feed segmentation: We divided the feed into five price tiers — from the most affordable items under €21 to premium pieces in the €121–161 range, as well as products priced below the market benchmark. Each tier had its own bidding strategy. Cheaper products generated click volume, while more expensive ones raised AOV. This approach allowed us to distribute the budget more efficiently towards the highest conversion probability.

Return control: We set a fixed target ROAS of 145%, ensuring healthy profitability even as investment volume grew.

Brand traffic exclusion: For maximum transparency, we strictly excluded branded keywords from the campaign. This eliminated cannibalization of organic traffic and ensured that the invested budget was directed primarily towards reaching new customers and building market share, rather than clicks from users who were already actively searching for the store.

The key moment came at the turn of November and December, when we managed to increase the number of clicks by 150%, which directly translated into revenue exceeding €10,600. December brought 189 more orders than the previous month, reflecting precise targeting and excellent management of seasonal demand.

Month-by-month development

While January brought the typical post-Christmas slowdown, March defined a new benchmark. Revenue of €34,960 in a single month surpassed the total results of the previous quarter.

Success analysis: Why did the numbers take off?

Several things went right at the same time.

1. A clean feed. Stradivarius had a well-structured product feed with accurate names, colours, and images. That is the foundation. Without it, the algorithm struggles.

2. Patience during the launch phase. October was deliberately slow. The campaigns needed to collect data without pressure for immediate results.

3. AOV grew with the collections. Spring pieces had higher price points than autumn ones. The average order value rose from €37 to €53. Higher prices did not mean a lower conversion rate.

Over six months, the collaboration between Stradivarius CZ and Selltor generated a total of €81,236 in revenue and 1,648 conversions. Q1 2026 outperformed Q4 2025 by 319% in revenue. AOV grew by 44% — and the conversion rate remained above 3%. That is a combination that is far from guaranteed in fashion e-commerce. More expensive products typically mean longer decision-making. Not here. The right segmentation brought in people who knew what they wanted.

Fashion stores with a wide product range and a high-quality feed are ideal for this type of campaign. Stradivarius proved it.
