Client-side A/B apps blank your store while a script picks a variant—shoppers stall and Core Web Vitals drop. ServerSideSplitter never runs that script. The variant is chosen server-side and the visitor is redirected by URL before a pixel paints: zero flicker, zero speed cost, no theme code. Point one URL at the Shopify pages you already built, split traffic across up to 5 weighted variants, and rank winners by real dollars per visitor. Stop hiding flicker. Ship instant split URL tests today.

• Zero flicker — the visitor is redirected server-side before a pixel paints
• Zero speed cost: no JavaScript on your storefront, Core Web Vitals untouched
• True server-side A/B testing by URL: 2–5 weighted variants, sticky visitors
• No theme code, no developer: build pages in Shopify, paste URLs, go live
• Pick winners by revenue, not clicks: RPV, AOV & conversions per variant
