A start-up ecommerce brand that sells pet products wants to test campaign structure. It would like to determine if it should have separate ad sets targeting different pet interest groups or consolidate all interest groups into one ad set.

The brand sets up a multi-cell Conversion Lift test for one month. At the end of the test, no results are available to review, due to insufficient statistical power.

Which two approaches should the analyst recommend? (Choose 2)

A. Run a campaign-level A/B test instead

B. Run a multi-cell Conversion Lift with fewer interest groups

C. Run a multi-cell Conversion Lift test with an increased holdout percentage

D. Review campaign results in Ads Manager instead
