“For a wine shop, the moment between a category page and a product page is where the sale is won or lost — and that moment has to feel instant. Speed Kit made our category and product pages noticeably quicker, and the A/B test shows in plain numbers that this speed converts into more orders and more revenue. Best of all, it slotted into our setup without a single change to our existing stack.”
Introduction
Hawesko is one of Germany's best-known names in premium wine, standing for fine vintages, champagnes and a carefully curated range built over decades. Through its online shop, hawesko.de, the company serves thousands of customers each day who explore an extensive assortment across many category and product detail pages. For a wine shop of this scale, the speed of category and product pages is decisive: this is exactly where shoppers decide whether to keep browsing or drop off. On image-rich overview and detail pages, every additional second of load time adds friction to the path to purchase. To live up to its customers' expectations, Hawesko introduced Speed Kit — with the aim of speeding up page delivery and making the shopping experience noticeably smoother, without touching the existing tech stack.
Challenge
With a continually growing assortment and a high proportion of image-heavy category and product detail pages, Hawesko wanted to clearly improve the load times of these core browsing surfaces — without reworking the shop architecture and without extra development effort.
Solution
Speed Kit was added as a lightweight optimization layer that sits on top of the existing shop — no architectural changes required. At its heart is predictive preloading: it anticipates which pages a visitor is most likely to open next and quietly loads them in the background. As a result, a large share of follow-up pages is served directly from cache or fully pre-rendered before the click. The payoff is a distinctly faster browsing experience — above all when moving between category and product detail pages, where speed drives dwell time and conversion.
Results
During the PoC phase, Speed Kit produced substantial LCP gains — most pronounced on the category and product detail pages, the shop's central browsing and decision surfaces.
Speed Kit ran a PoC test phase over two weeks: a Speed Kit-accelerated group was measured directly against an unaccelerated control group.
- Revenue: +3.26% (relative, between groups)
- User conversion rate: +1.73% (relative)
- Transactions / orders: +1.72% (relative)
- Average order value: +1.52% (relative)
Statistical significance: the +1.73% relative uplift in user conversion rate is statistically significant at a 90% confidence level (p ≈ 7.3%). The improvement is not attributable to random variation.
Conclusion
For Hawesko, page speed translates straight into commercial results. By cutting Largest Contentful Paint on the pivotal category pages by 377 ms (~43%) and on product detail pages by 129 ms (~17%), and by preloading a large share of follow-up pages, browsing the range becomes noticeably smoother. The PoC phase makes the business impact unmistakable: a +1.73% relative uplift in user conversion rate and a +3.26% relative revenue uplift — statistically significant at a 90% confidence level. Speed Kit is now a permanent part of Hawesko's performance stack, ensuring every visitor enjoys a faster, seamless shopping experience.
