GA4 added 2 new reports:

• Lead Acquisition - User-scoped data mostly focused on attributes, for first-time visitors
• Lead Disqualification and Loss- Shows reasons why potential customers didn't convert

Both found under Reports > Business objectives > Generate leads

If you don't see "Business objectives" in your GA4 report sidebar you can add it from the Library (last option in sidebar - go to Collections & publish it).

Important: These 2 new reports don't show any data until you set up with the exact event names Google wants.

Already seeing them in some of the GA4 accounts we monitor...
