By default, new Performance Max campaigns turn on Final URL expansion. This means that Google can send searchers to a different landing page for better conversions. Expanding the Final URL can be worthwhile, but it's important to see which pages are converting. An option in the "Assets" tab provides the Final URL expansion assets. Advertisers can exclude irrelevant URLs in "Asset Optimization" within the campaign settings. Click on the "Customization" option to activate "Final URL expansion."
