What it does
Put version A in one place and version B in another, and the better place can win for reasons that have nothing to do with the copy. A magazine may reach richer readers. A town may have a bigger market. You pick the wrong winner and think you learned something. This skill sets up a cross-over test. Each version runs in half of the matched places with equal spend and its own key. In round two the versions swap places. The same follow-up goes to every reply, and you compare cost per reply and then the sales each version led to. The result is a winner you can trust, and a record to reuse.
You give it
- Two versions of the copy
- The places they can run, with the cost of each
- What counts as a reply and what the follow-up is
- Past results for these places (optional)
- Your results (optional)
You get
- A split of places into two matched halves
- A keyed plan for round one and a swap for round two
- A report format: cost per reply, then sales per version
- A winner rule and a record sheet
