When creating a campaign experiment, which is a best practice?
- Choose two or three metrics that can be used to reliably gauge campaign performance and determine the winner of a particular test.
- After the end of an experiment, assess performance over a period of time that includes ramp-up.
- Isolate one variable to focus on for each test and use different tests when assessing the impact of more than one change.
- As a means of expediting experiments, new ads aren’t subject to the same approval process during time of the experiments.
The correct answer is:
- Isolate one variable to focus on for each test and use different tests when assessing the impact of more than one change.
