How does analytics reporting work?
Generated sites send direct GA4 events with hostname, subdomain, and site_id so reports can be separated by domain and tool.
How is site search tracked?
The local search form pushes a site_search event with search_term, hostname, subdomain, and site_id.
Is this professional advice?
No. Use it as a practical organizer or calculator and verify important outputs with the right source or specialist.
