StyleHub — Shopify Plus rebuild + 4-week CRO sprint

A fashion brand on a leaky Shopify Standard store with an 11-month sales plateau. We rebuilt on Shopify Plus with Hydrogen and ran a CRO sprint that lifted conversion 42% and dropped CAC by 31%.

What we were handed

StyleHub had a Shopify Standard storefront built three years prior. Revenue had plateaued for 11 months despite increasing paid spend. Page-speed scores were red, mobile UX was broken in subtle ways (cart drawer didn't show on iOS Safari), and the brand had grown out of the visual style of the existing theme. They needed a rebuild — but they were nervous about traffic loss during migration and skeptical that a redesign alone would move conversion.

How we framed it

Two-phase engagement: rebuild then optimize. Phase 1 (weeks 1–8) was a Shopify Plus migration with a Hydrogen-based headless storefront for the homepage and PDPs (kept Shopify checkout for security/SOC compliance). Phase 2 (weeks 9–12) was a focused CRO sprint with a written hypothesis backlog, statistical-rigor A/B testing via GrowthBook, and weekly ship-or-kill decisions.

What we shipped

Headless storefront on Hydrogen + Sanity CMS for editorial flexibility, Shopify Plus checkout extensions for upsells and shipping logic, Klaviyo for email/SMS with new flows for abandoned cart and post-purchase, Yotpo for reviews with structured-data integration so reviews show up in Google rich snippets. All 47 existing collection URLs preserved via 301 mapping. Performance budget: LCP < 2.0s on mobile (achieved 1.6s median).

What happened

  • Conversion rate increased 42% on mobile, 28% on desktop within 90 days of launch.
  • CAC dropped 31% — same paid spend, but a much better-converting destination.
  • $1.2M incremental annual revenue attributed in the year following launch.
  • Zero ranking loss during migration — actually gained 18% organic sessions in months 3–6.
  • CRO sprint identified 7 high-impact tests; 4 shipped as winners, 2 killed, 1 inconclusive.

Two prior agencies told us our problem was traffic. ApexGenLabs ran one week of diagnostics and showed us we had a conversion problem masked by paid spend. The fix paid for itself in five months.
