Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• The Advanced Data Breakdown setup notices within both the Site goals widgets should be updated to the latest title and description as per the Figma mocks for:
• Within widget:
  • Lead generation widget
  • Online store performance - Only one eCommerce provider ( either WooCommerce or EDD)
  • Online store performance - 2 eCommerce providers installed (both WooCommerce and EDD)
• Within side panel:
  • Only lead dimensions missing - same as Lead generation widget above.
  • Only online store performance dimensions missing - same as both online store versions above.
  • Both, lead and online store dimensions missing with only one eCommerce provider active
    • No figma available but the title and description should be as follows:
    • Title: Have multiple forms, or selling products or services?
    • Description: If you use multiple forms or sell products, your events data might be grouped together. Enable this breakdown to see results for each form and product source separately and track how each one is performing. Because this uses a new, more precise tracking method, your data will start fresh from the moment you turn it on. Learn more
  • Both, lead and online store dimensions missing with both, WooCommerce and EDD active

Implementation Brief

• Update the text appropriately within assets/js/modules/analytics-4/components/site-goals/notifications/useSiteGoalsBreakdownNoticeCopy.tsx.

Test Coverage

• No new tests required.

QA Brief

• Ensure all custom dimensions are deleted on a connected analytics property to test the "both" requirements in the AC.
• Then let site kit create all the custom dimensions by enabling breakdown. Now go to the analytics property and delete only the googlesitekit_form_id custom dimension to make the "Only lead" case true. Or simply have a detected event set for the Lead generation widget (i.e. contact or submit_lead_form)
• To test the "only ecommerce" case, set the detected events in the tester plugin to only be purchase.

Changelog entry

• Update notice text for Site Goals.
