A random collection of A/B tests rarely produces systematic conversion improvement. A structured testing programme — with evidence-based hypotheses, properly calculated sample sizes, clear primary metrics, and a prioritised roadmap — turns experimentation into a reliable growth engine. We build your CRO testing programme: working from analytics data and qualitative research to develop a prioritised backlog of hypotheses, then designing each test with proper statistical rigour.

Frequently Asked Questions

A good hypothesis identifies a specific problem (observed in data/recordings), proposes a specific change, and predicts a measurable outcome. 'We believe [change] will improve [metric] because [evidence]' is the standard format.
On different, unrelated pages — multiple simultaneous tests are fine. On the same page — tests can interact, so typically run one test at a time per page unless using a multivariate approach.
Based on current conversion rate, minimum detectable effect (how small a change is worth detecting), and statistical power (usually 80%). We calculate these upfront so tests run long enough to be conclusive.
95% confidence (p < 0.05) is the standard. For high-stakes changes, 99% confidence. We advise on the right threshold based on the risk profile of each test.
Don't stop early — early stopping is a common mistake that causes false positives. We pre-commit minimum runtime and sample sizes before launching each test.
