Single Variable Testing

Taught on 2025-04, 2025-01-23

What this is

Change one thing at a time so you can actually attribute the result.

Run it

1. Pick ONE service that is in striking distance.
2. Do all the work on that one service for a week, two weeks, a month.
3. Watch the tracked calls tagged to that service.
4. Only then change the variable.
5. Related discipline from the same call: minimum-viable-product website, avoid topical dilution so the signal stays focused.
