FAQs
Q: Do I need a Shopify-specific CRO agency? A: Not necessarily, but it helps significantly. Shopify-specific expertise means the agency understands Liquid templating, the app ecosystem, checkout constraints, and Shopify Analytics, reducing ramp-up time and improving test quality. A generic CRO agency can work, but expect 4–8 weeks ramp-up vs. 1–2 weeks for Shopify-native.
Q: How much should I budget for Shopify CRO? A: For meaningful results: $3K–$15K/month for agency services, or a free AI audit to start. Rule of thumb: 10–20% of incremental revenue generated. A $10M/year store should budget $3K–$8K/month and expect 20–35% CVR lift (worth $200K–$700K annually).
Q: Can I do Shopify CRO myself? A: Yes. Start with an AI audit to identify your highest-priority issues, implement quick wins yourself (product pages, trust signals, mobile), and consider an agency for complex experiments that need design and development. Many stores do 60% of work in-house and hire agencies for execution.
Q: What’s the difference between acceleroi and traditional Shopify CRO agencies? A: acceleroi uses AI to audit and prioritize tests (minutes vs. weeks). Traditional agencies (SplitBase, The Good) use manual research and human-led prioritization. acceleroi is faster and cheaper; traditional agencies are deeper on qualitative research. Best fit depends on your team’s capacity and timeline urgency.
Q: Which agency is best for Shopify Plus stores? A: Blend Commerce specializes in Shopify Plus technical optimization. For Plus stores under $50M, acceleroi or SplitBase are stronger CRO choices. For Plus stores over $50M with custom checkout needs, Blend Commerce or Swanky. Most Plus stores benefit from hybrid: acceleroi for quick wins, Blend for technical depth.
Q: How do I measure whether a Shopify CRO agency is working? A: Track month-over-month improvements: CVR, AOV, revenue per visitor, and cart abandonment rate. Expect 15–25% CVR lift in first 3 months. If not seeing lift within 4 months, it’s not working. Ask for test velocity (how many tests per month) and documented results (case studies, not just claims).
