What can you test using campaign drafts and experiments besides ad variations?

• A. Keywords
• B. Landing page color variations
• C. Alternate bidding strategies
• D. Ad extensions

Answer: (C)

Campaign drafts and experiments let you compare a proposed change to your current setup in a controlled, split‑traffic way. The key idea is to isolate the effect of a change by running an experiment between the original campaign and a draft that includes the change. The most straightforward change to test besides ad variations is a different bidding strategy. You can create a draft with a new bidding approach—such as moving from manual CPC to Target CPA or Target ROAS—and run an experiment to see how this affects conversions, cost, and overall efficiency before applying it broadly. This approach gives clear insight into whether the new bidding logic improves performance without altering other elements of the campaign. While you can test other components in different ways, bidding strategy changes are a primary, well-supported use of campaign drafts and experiments.
