Testing & Iteration
How do I know if a change actually helped?
Decide the number before you change anything, then give it a full business cycle. Compare like periods, not this week against last week when a campaign was running. If you can't isolate the change, at minimum write down what you did and when, so the record exists later.
Next moves
- Test one meaningful thing at a time, and make it big enough to matter.
- Decide the win condition before you launch the test.
- Below real traffic volume, prefer judgment and qualitative feedback over statistics.
Bring your traffic numbers. They decide whether testing is a real tool for you yet or a distraction.
