A dog eats a bag of grapes at 9 p.m. The owner searches, taps your ad, and calls. Twenty minutes later they are in your lobby. Your team saves the dog. Google Ads records nothing, because nobody told it a phone call or a car in the parking lot was the thing you were paying for.
Multiply that by a month and the account decides your best searches don't work, then moves budget toward whatever it can measure. So the guide starts here, before keywords or bids: every later chapter depends on Google learning from real new clients.
A Vet Practice Has Four Front Doors. Most Accounts Count One.
New clients reach a veterinary practice in four ways. They call. They book online. They fill out a request form. Or, in an emergency, they just show up.
Each door needs its own counter, because conversion tracking does two jobs. It is the report you read, and it is what steers your money: Google's automated bidding studies every recorded conversion and hunts for more searches like it. Exploration (BrandRocket's term for the broad-match campaign Chapter 6 sets up) needs a steady supply of those examples.
To see how the four doors show up in real practices, we looked at one example market, Denver: 12 veterinary websites that ran Google Search ads in the last 90 days, from general practices to 24-hour emergency hospitals, an in-home euthanasia service and a nonprofit clinic. Your market will differ; the doors won't.
- Four take new clients by phone, email or walk-in, with no online booking on the day we checked.
- Four run their own booking system on their own website.
- Three embed a scheduling vendor's widget on their pages.
- One takes appointment requests through a form.
An account that counts only form submissions is blind to three of those doors. For most practices, the biggest of the three is the phone.
The Phone Is the Main Door. In One Study, 15% of Calls Never Reached a Person.
In 2025, researchers for a study published in the Journal of the American Veterinary Medical Association posed as new clients and called 5,053 general practices, which they found the way an owner would, on Google Maps. Here is what happened to those calls:
- 67.0% ended with an appointment.
- 15.1% failed because nobody picked up.
- 8.2% failed on hold times long enough to give up.
- Only 3.9% failed because the practice had no room for a new patient.
A missed call lost almost four times as many new clients as a full schedule did.
Google Ads can track calls three ways. It can count calls placed straight from your ads, through a call asset or a location on the ad. It can count calls to your website's number, by showing a Google forwarding number to visitors who arrived from an ad, which Google describes as calls made "when someone clicks on your ad, then calls the forwarding number we display on your website." And it can count taps on the phone number on your mobile site, which record the tap rather than the conversation.
The first two come with call reporting, and that is where a vet practice learns something it can act on. For each call, Google records "call duration, call start time, caller phone number... and whether the call was connected." A practice that sees unconnected ad calls pile up at 12:30 or after 5 p.m. has found a staffing problem no bid change will fix.
You choose a minimum call length, and every call that lasts at least that long counts as a conversion. We set it at 30 seconds. A worried owner who reaches voicemail and leaves a 40-second message about a limping dog is a new client you paid for.
Two patterns in our example market make calls harder to count. Three of the 12 show three or more different phone numbers on different pages, so an owner can call any of them and your tracking needs to cover every one. And two advertise "call or text" numbers. Google's call tracking counts calls. Texts to that number never reach your conversion column, so if texting is a real way new clients reach you, log those leads somewhere you can bring back into the account.
Online Booking Counts Only When Google Can See the Confirmation
The clean version is a booking system on your own website. Banfield's hospital pages send owners to a scheduler on banfield.com, and Modern Animal's clinic pages show open time slots from its own booking app. When the confirmation screen lives on your site, your Google tag can fire on it, and Google counts a booked visit.
Three of the example practices embed a vendor's scheduler instead, using tools such as VetEngage, PetDesk with Vetstoria, and a scheduler that loads in a frame from the vendor's own domain. The widget sits on your page, but the booking itself may happen inside the vendor's frame, where your tag can't reach.
Put two questions to your scheduling vendor. At the moment an appointment is confirmed, can the scheduler trigger your Google tag or push an event into Tag Manager? And if booking moves to another domain, does the Google click ID travel with the owner? When both answers are no, count the click that opens the booking tool as a secondary action, and import confirmed new-client bookings from your practice software later. For moves between domains you own, Google Analytics offers cross-domain measurement.
Whatever you do, don't make "Book Now" clicks your main conversion. Plenty of owners open the scheduler, see no time before Thursday, and call the emergency hospital down the road.
Request forms can carry more than a name and a number. Cherry Knolls Veterinary Clinic's appointment form asks "What is this appointment for?" and offers vaccines, an annual wellness exam, a spay or neuter consult and a dental consult. Every request arrives labeled by service, which is exactly what you want when Chapter 7 asks which services are worth bidding up.
An Emergency Hospital's Best Lead Walks In Without an Appointment
Emergency medicine breaks the booking model on purpose. VEG, a 24-hour emergency group advertising in our example market, puts it plainly: "we don't take appointments, because you can't plan for an emergency." Its location pages offer a "Start Now" button that opens Google Maps directions.
For an emergency hospital, then, the conversion that matters is a car pulling into the lot, and Google can't see the lot. It can see the steps just before it.
The Directions click. When your ads show your address through location assets, Google records clicks on "Directions" or "Start" as a local action. Google says local actions are "available for all advertisers with active location assets," and Directions is one of the two local actions it lets you bid toward, in Search, Performance Max and Shopping campaigns. It lands in the All conversions column, so add "Get directions" as a goal on your emergency campaigns if you want bidding to use it.
The directions and call buttons on your own site. Tag the click on your map link and on your phone number, so an owner who taps "Start" on your emergency page counts even if they never phone ahead.
The call. Many owners call on the way in. Those calls count through call tracking, like any other.
What Google can't count is the owner who read your ad, remembered your name and drove over without touching anything. Catch that one at the front desk. Pets on Broadway's new-patient form asks "How did you hear about us?" and lists "Internet" among the choices. A question like that, asked of every new client, lets you check Google's numbers against your own each month.
Refill, Pharmacy and Portal Clicks Are Existing Clients
Your website also serves the clients you already have, and much of that traffic leaves for other domains. On the example sites, online pharmacies run through Covetrus and Vetsource, and pet records and refill requests sit on portals from AllyDVM and ezyVet.
That matters because a popular shortcut is to count every click to an outside site as a conversion. On a vet site, that rule counts every longtime client reordering flea and tick prevention as a new one. Google would get very good at reaching owners who already have a vet, and those owners were never the point of advertising.
Keep pharmacy, refill and portal clicks out of your primary conversions. If you want to watch them, add them as secondary.
Set Up Every Conversion Before the First Click
Primary and secondary. Make booked new-client visits, new-client request forms, qualifying calls and, for emergency campaigns, Directions clicks your primary actions. Bidding learns from primary actions. Secondary ones stay out of the column bidding reads and show up only under All conversions. That is the right home for "Book Now" clicks and pharmacy visits.
Count one. An owner who submits the form and phones the next morning to double-check is still a single new client. Google's one-per-click counting option exists for exactly this, and Google points lead-generation advertisers to it.
Conversion window. Google's click-through window runs from a single day up to 90, depending on where the conversion comes from, and starts at 30. Owners planning spay surgery or a dental cleaning often click, compare a few clinics and book weeks later. We set forms and bookings to 90 days and calls to the longest window Google allows for them.
Attribution. Choose data-driven attribution, so credit is shared among the searches an owner made on the way to booking.
The old checkbox. Some conversion screens still show a box for enhanced CPC, a bidding option Google has retired. Leave it empty.
Enhanced conversions. This feature sends hashed contact details, such as an email address, with each conversion so Google can match it more accurately. Practices in human medicine can't use it, because Google's customer data policy treats buying medical services as sensitive health information and keeps those conversions out of enhanced conversions. That policy never mentions animals, and HIPAA, the federal health privacy law, covers people rather than pets. Our reading is that a vet practice can use enhanced conversions for leads. Google doesn't say so in those words, so watch the account for a policy notice after you turn it on. State veterinary practice laws still govern what client information you may share, so check yours before you send any. (This isn't legal advice.)
Install every tag through Google Tag Manager, switch on auto-tagging in Google Ads, and walk through each door yourself in Tag Assistant: call the tracked number, book a test visit, submit the form, tap Directions. Watch each one arrive before a single ad goes live.
Page Views and "Book Now" Clicks Teach Google to Find Browsers
If your account is already running, open its conversion actions before touching anything else. Look for page views dressed up as leads: someone reached the contact page, the new-client page or the pricing page. Look for "Book Now" clicks sitting in the primary column.
Every one of them is a lesson Google is still learning. A visit to your dental cleaning page is curiosity. Put it beside real bookings and Google will happily buy more of whichever is cheaper, and curiosity is always cheaper.
Move those actions to secondary or remove them before launch. When most of an account's history rests on them, starting the conversion data fresh can beat asking Google to forget. The account loses a few months of numbers and keeps none of the bad habits.
Next: The Midnight Emergency and the New Puppy Aren't the Same Search
Once calls, bookings, forms and walk-ins are counted, Google finally learns from real new clients. The next decision is which searches to meet. An owner typing "dog ate grapes" at midnight and a family searching for a vet for their new puppy want different things from you, and Chapter 2 maps where each kind of search sits and where your ads should start.
