What action starts an ad variation test in Google Ads?

• A. Creating a new ad variation under Experiments in Campaigns
• B. Duplicating an existing campaign manually
• C. Modifying budget for all campaigns
• D. Running a standard performance report

Answer: (A)

The action that starts an ad variation test in Google Ads is creating a new ad variation under Experiments in Campaigns. This sets up a controlled split where part of your traffic sees the original ads and another part sees the variation, allowing you to compare performance directly. To do this, you go to Campaigns, open Experiments, and create a new ad variation based on your current ads, specifying the changes you want to test (such as a different headline, description, or landing page). You also choose how to split traffic (for example 50/50) and set the test duration. Once started, Google Ads runs the experiment and provides results showing how the variation performs against the original, using metrics like click-through rate, conversions, and cost per conversion. Other options—duplicating a campaign, changing budgets across all campaigns, or running a standard report—do not initiate a controlled ad-variation test.
