How do you set up an ad variation test in Google Ads?

• A. Go to Campaigns, click Reports, and run a standard report
• B. Go to Campaigns, click Experiments, create a new ad variation, and follow prompts
• C. Go to Audience, create a new audience, and apply to campaigns
• D. Go to Tools, create a shared library, and apply to campaigns

Answer: (B)

Ad variation testing in Google Ads is done through the Experiments feature found under Campaigns. This tool lets you run a controlled change against an existing campaign so you can compare how the variation performs versus the original.

To set it up, open Campaigns, choose Experiments, then create a new ad variation and follow the prompts to configure the test—define the variation, choose how much of your traffic will see the variation, set the duration, and select the campaign to test. The experiment runs alongside your current campaign, and you’ll be able to compare metrics like click-through rate, cost per click, and conversions to determine which version performs better.

This approach is preferable to making ad changes directly in the live campaign, because it preserves a clear control and provides valid comparative results. Other options described involve analyzing data after the test, adjusting audience targeting, or using shared assets, none of which actually set up an ad variation test.
