So a dental site sits somewhere most local business sites never get to sit: it is the transaction, not the shortlist that leads to one. The search, the insurance check and the appointment all happen inside the same ten minutes, very often late in the evening when nobody is answering your phone. If the site names their carrier, shows them the room they will be sitting in and takes the appointment there and then, it has done the entire job. If it hands back a phone number and office hours, it has handed the decision to someone who was already looking for a reason to postpone.
