Google Ads conversions but no leads usually means the account is counting events and your front desk is counting people. The first job is to find out which of four causes raised the number, because only one of them is real demand.
Quick answer
- Ask why each primary action is primary; a button click or page view should not be.
- Make one test booking with Tag Assistant open and count the conversion hits.
- Check the minimum call length on your call action and who set it.
- Compare the same weeks per office against the front desk's new-patient totals.
Why the two counts differ before anything breaks
A perfectly set up account still disagrees a little with the front desk. Google documents three reasons.
First, the primary conversion columns are calculated by the time of the click, not the time of the conversion. A patient who clicks in March and books in April shows up in March in Google Ads and April at the front desk.
Second, the Conversions column reports modeled conversions as well as observed ones. Modeled conversions are Google's estimates for the ones it cannot observe, and they can take up to 5 days to settle. Last week's figure moves.
Third, check which column you read. Only primary actions enter the Conversions column. Secondary actions show in "All conversions" and are for observation only.
Four causes side by side
The sign column says what to look for in your own numbers.
| Cause | The sign | Who checks | The fix |
|---|---|---|---|
| A click counted as a booking | Conversions jump when a banner or button changes, patients do not | Whoever runs the ads | Move the click to secondary, keep the finished booking primary |
| One booking counted twice | Two primary actions rise together | Web developer or agency | Keep one source per booking |
| Calls credited wrongly | Call conversions rise, front desk logs repeat patients | Front desk lead with the call log | Check the minimum call length, count only new-patient calls |
| Real demand | Front desk totals rise too | You, from monthly totals | Nothing to fix |
Real demand sits last because it is the only row where the front desk count rises too.
One booking, two counts
A booking tool embedded on your site can send its own conversion event when a patient finishes. If your website also has a conversion tag on the thank-you page, one booking sends two hits. Both feed the Conversions column when both actions are primary.
A thank-you page that reloads or opens in a second tab repeats the same action. With the count setting on "One", which Google describes as the choice for leads, the repeat no longer counts. It works per action, so it does not merge the tag and the widget.
Calls counted for the wrong patient or office
Unless call recording is on, a call becomes a conversion by its length, and Google does not know whether the caller is a new patient. You set a minimum call length, and every call at least that long counts. Google's Help page on call conversions states no default, so read yours. The same page offers another route: import call conversions from a system that marks new patients.
A shared call center adds a second problem. Google credits the ad the caller dialed, but a shared call center may book that patient at another office. For the office-level view, see which office got the lead. Local Services Ads leads sit in their own lead inbox and reports, so count them apart, as in Local Services Ads versus Google Ads.
One test booking with Tag Assistant open
This is a ten-minute job on a desktop Chrome browser.
- Install the Tag Assistant Chrome extension and start a debug session on your booking page.
- Book a real slot yourself, using a test name your front desk knows to ignore.
- On the confirmation page, look at what fired and count the Google Ads conversion hits.
- One hit means one source. Two means something else reports the same booking: a second tag, a reload or the booking tool's own event.
The full walkthrough is in checking conversion tags with Google Tag Assistant. If the numbers still disagree, try the click id test in Google Ads shows more leads than your CRM.
Prove it with the same weeks, office by office
Put the same weeks side by side per office: Google Ads conversions by action from the "by conv. time" columns, and the front desk's new-patient count per office. Use numbers only, no names.
Rerun the comparison four weeks after the fix, leaving out the last 5 days while modeled conversions settle. If both counts now move together, the account is counting bookings again.
Where the 2024 tracking ruling leaves this
This is not legal advice, and I am not a lawyer. The measure above uses monthly totals, so no patient-level data goes to an ad platform. On June 20, 2024, a federal court in the Northern District of Texas vacated part of HHS's online tracking bulletin. It struck the part tying HIPAA to an IP address combined with a visit to a public page on a health condition or provider.
Booking pages kept their warning: HHS says a tag on a scheduling page with no login may capture PHI (protected health information), like a typed email address or the reason a patient gives for booking. The government moved to drop its appeal on August 29, 2024, and HHS says it is weighing its next steps.
So keep condition names out of booking page URLs and titles that reach an ad platform. In Canada, PIPEDA guidance from the federal privacy commissioner allows opt-out consent to behavioural advertising only when the tracking avoids medical or health information, among other conditions.

Frequently asked questions
Why does Google Ads show conversions when my front desk sees no new patients?
Google counts events that a tag or a phone call recorded, and your front desk counts people who came through the door. A button click, a second tag on the same booking or a call from an existing patient each add a conversion and no patient. Start by listing which actions sit in the Conversions column.
Can Google Ads count one booking twice?
Yes, when two things report the same booking, for example your site's tag and the booking tool's own event. If both feed a primary action, each booking adds two. A test booking with Tag Assistant open shows how many hits one booking sends.
Do I need patient records to check my Google Ads numbers?
No. Monthly new-patient totals per office from your front desk are enough, next to Google Ads conversions by action for the same weeks. Nothing about an individual patient has to leave the practice.
Should I count every call as a conversion?
Only calls long enough to be a real inquiry, and ideally only new patients. Google lets you set the minimum call length, so check yours instead of assuming it. A call from an existing patient is real, but it is not a new booking.
Why doesn't last month in Google Ads match last month at my front desk?
Google puts a conversion in the month of the ad click, not the month the patient booked. A click in March and a booking in April land in different months in the two counts. The 'by conv. time' columns in Google Ads sort the same conversions by when they happened.
