Call-only ads for a clinic with no online booking: worth running?

Take a dental clinic asking whether call-only ads are worth it, because their site is mostly a brochure and they'd rather not send traffic there. I think they can work, since someone in pain usually wants to talk to a person, not fill out a form. But the format lives or dies on whether the phone gets answered. If calls go to voicemail after 5pm or the front desk is slammed, you're paying for clicks that never turn into bookings, and the dashboard doesn't make that obvious. The rule I'd follow is to run them only during hours when someone can actually pick up, and to track missed calls next to answered ones. Curious how others handle the after-hours gap.

Agreed on the schedule, but I wouldn't count on Google Ads to show you the missed calls. Standard call reporting mostly tells you a call happened and how long it lasted, so one that rings 15 seconds and drops to voicemail doesn't reliably show up as unanswered. For a clinic, the phone system's own log is the more honest source. Pull the unanswered and voicemail counts for the hours the ads ran and compare them with the calls Google reported. If the gap is big, shorten the schedule before you touch the budget.

Agreed on the phone log being the right source. One thing that makes the comparison cleaner is the minimum call duration on your call conversion. If it's set low, a call that rings twice and drops to voicemail can still count, so Google's numbers will look better than what actually happened. Set the threshold to roughly the length of a real booking conversation, then compare only those calls against the phone system's answered count for the same hours. And make sure the forwarding number is one you can tie to a specific time window, because otherwise the matching gets messy fast.

Raising the minimum call duration doesn't fix this. It tells you nothing about whether the phone actually got answered, it just filters Google's side, so you end up comparing a filtered count against an unfiltered phone log. A 90-second call can be a patient asking about hours, and a 20-second call can be a booking that went fast because the receptionist already had a slot open. I'd compare total connected calls per hour in Google against answered calls from the phone system, then look at how many of those answered calls turned into real appointments. That last number is the one that tells you whether the ads pay.

Agreed, answered-to-booked is the number that matters. But Google can't see the booking, so the call source has to get recorded on the appointment at the front desk, or the ratio is just guesswork. Does their scheduling tool let staff tag where a booking came from?

A dedicated call-only number helps a lot here. If it only shows up in the ads, not on the website or Business Profile, every call on it came from the ad, so the front desk doesn't have to guess. Scheduling tools usually have a referral or "how did you hear about us" field, but it tends to be free text that staff skip when the phone is ringing. A short dropdown with a "Google call ad" option gets filled in far more reliably. Just make sure the clinic owns that number and can route it through their phone system, otherwise the tracking breaks the moment someone changes it.

Agreed on the dropdown. One rule of thumb for judging the result: don't decide anything until you have at least 20 to 30 answered calls. A clinic getting eight answered calls a week can see its booking rate swing from 10% to 60% because of one busy Saturday, so the early numbers are mostly noise. Set the bar before launch, something like "keep it running only if about one in three answered calls becomes a booking," and review once you hit that volume. Deciding in advance keeps one good week from looking like proof.
