Before and after a change
Compare the outcome without losing the surrounding context.
Review a known change
Compare [KPI] for [campaign] during the 14 days before and after [change] on [date]. Show spend and conversions alongside it, plus other changes in the same period.
Check whether the baseline is fair
Show the daily trend for [campaign] during [date range]. Compare the two weeks after [date] with the two weeks before. Are there missing days or recent conversions still affecting the comparison?
Turn the review into a follow-up
Save the view and start a Tracker if you want to keep following the result. Write down the outcome you expect and when you will review it.
Before and after is not an A/B test
Two time periods can differ for reasons beyond the selected change. A controlled experiment and a historical comparison answer different questions. Use the account’s experiment reporting when you need an experiment result.
