The call that rings out at 12:40 is the most expensive leak in the practice
Missed calls during lunch, huddles and the hour after close account for more lost patients than any page element.
Pull your call log by hour and day of week. Count the unanswered calls and the ones under fifteen seconds, which are usually somebody hitting an automated greeting and giving up.
The pattern is almost always the same: a hole over lunch, a hole during the morning huddle, and everything after five o'clock. New-patient calls do not respect that schedule.
Fix the coverage before touching the website. Staggered lunches, an overflow service that can actually place an appointment rather than take a message, and a rule that missed calls get returned within minutes rather than the next day.
Speed of callback beats almost every other intervention available to you. A person shopping for a dentist is calling three practices, and the first human voice usually wins the case.
