Respect sample limits
Low traffic may not support a reliable split test. Use task testing and measured improvements rather than claiming statistical certainty from a small sample. Explain which task matters next and why it takes priority.
Define the audience and conversion action before calculating a rate. A change in traffic quality can alter the rate even when the page has not changed. Leave the team with a decision, an owner, and a review date.
- A written brief
