On a corporate website the visuals and content play the main role. With an e-shop it's different, every screen decides an order. The product page, the cart, shipping and payment, registration, form validation. All it takes is one unnecessary extra field in checkout and 30% of users drop off.
I work with data: product page heatmaps, cart session recordings, drop-off analytics, payment A/B testing. First I find out where you're really losing orders. Then I redesign those specific screens, not the whole e-shop 'because it looks dated'.
I have experience with Shoptet (official Cookbook), Shopify (Czech market, Zasilkovna/PPL), Custom Next.js (headless). I know where each platform has a bottleneck and what to do about it. After a redesign we usually continue with a monthly CRO partnership, ongoing A/B tests and optimization of product pages.
