Requirements
You need to enable the following features in your campaigns to participate in optimization experiments.
- Campaign Eligibility: Ensure the campaign is active, is not part of another experiment, and its "Final URL" setting for "text customization" is turned off. Learn more about Controlling text customization in Performance Max campaigns.
- Text customization: Treatment arm traffic will show ads generated with text customization and Final URL Expansion turned on, and control arm traffic will show ads generated with the campaign's original settings.
- Budget: If your Performance Max campaigns are budget-constrained, we recommend increasing your budget to ensure experiment success.
How it works
-
Control: A Performance Max campaign with current text customization and Final URL settings.
- Treatment: The same Performance Max campaign with text customization and Final URL settings enabled.
Note:
- Instead of creating a new campaign for the treatment arm, some fraction of the traffic within the existing Performance Max campaign will be diverted to control and treatment campaigns.
- You can now specify URLs to exclude. This allows you to focus on testing the performance impact of Final URL Expansion on your selected landing pages.
- When using page feeds with Final URL expansion on, the page feed helps to verify that we’re indexing the provided URLs, but it doesn’t restrict ads to serve only URLs from the provided feed. Learn more about How to use page feeds in Performance Max.
