Agency source reviewedConversion rate optimization agencies: scope and selection criteria
Commission a diagnosis and experiment process tied to a measurable visitor action.
When this scope fits
Use this scope when the action is instrumented and the team can implement changes. If traffic is too low for a reliable split test, prioritize research and usability fixes without presenting them as causal experiments.
Questions that expose the scope
- What evidence supports the proposed hypothesis?
- Who decides sample requirements and stopping rules before launch?
- How are negative or inconclusive results documented?

A redesign is not automatically an experiment. Statistical confidence and revenue uplift cannot be promised from insufficient data.
Questions and answers
Is every increase a winning test?
Check sample, duration, audience balance and the pre-agreed metric. An observed increase alone is not a causal conclusion.
What if there is too little traffic?
Buy research and clearly scoped improvements. Label the evidence correctly and avoid pretending an underpowered split test proves a result.
