A valid A/B test needs enough conversions on each variant to distinguish a real effect from noise. For a store converting at 2%, detecting a 10% relative improvement takes on the order of tens of thousands of sessions per variant. That is weeks of traffic for a mid-sized store and months for a small one.
This is not a reason to avoid CRO. It is a reason to be suspicious of any proposal promising a test cadence your traffic cannot support, and of any result declared after four days because it “reached significance” — peeking at a running test and stopping when it looks good produces confident, wrong answers reliably.
Under roughly 1,000 orders a month, split testing will not produce trustworthy results at any useful speed. What is still worth buying at that scale is research: session recordings, usability sessions with real customers, funnel analysis, and fixing the things that are simply broken.
That work has no statistics attached and is often more valuable than testing anyway, because early-stage stores rarely lose orders to subtle wording. They lose them to a shipping cost revealed at step three.
Research-led engagements — audit, recordings, user testing, a prioritised list — are commonly $4,000–$15,000 as a project. An ongoing testing programme with implementation included runs $4,000–$20,000 a month and needs the traffic above to be worth it. Performance-based pricing exists and is usually structured so that ordinary seasonal growth pays the fee; read the baseline definition carefully.
