Where do property inquiries usually drop off before a site visit?

I’ve been looking into why property inquiries don’t convert into site visits.

From what I’m seeing, the gap usually happens after the inquiry, follow-ups are manual, inconsistent, and there’s no clear qualification structure.

For agents here:

Do you have a defined process for moving inquiries toward site visits?

Or is it mostly handled case-by-case?

Curious what’s actually working right now
