GA4 is replacing UA very soon.
Setting up single site of GA4 is straight forward, however I need advice in terms of WordPress Multisite and configuring for GA4 as a whole (xxxx.com) and all subsites (xxxx.com/A, xxxx.com/B, xxxx.com/C……..etc)
Few important notes that I need advice:
1. In previous UA, I do have different property for main site (xxxx.com) and all subsites (xxxx.com/A, xxxx.com/B…..). Do I need to create different GA4 properties for each subsites?
2. Any example to capture “custom events” such as enquiry forms that appear at different places, different conditions over website (main site + subsites)? Particularly I have a enquiry form at 80% of the pages where the form embed as top footer widget. How I can track the form being submitted from which page?
3. How to define funnel (example visitor landed at Page A, then go to Page B, Page Z, Page D……. and exit at Page F)?
Any other tips regarding Multisite and GA4 as references?
