Advertising cost is usually quoted as a monthly figure, which is the least useful way to think about it. The number that decides whether any of it works is the cost of one new client compared with what that client is worth to you.

Start there and the rest becomes arithmetic.
What a new veterinary client is worth
A first visit is not the value. A client who stays brings annual wellness visits, vaccinations, dental work, and at some point something unplanned and expensive. Across a typical relationship that is several thousand dollars of revenue, spread over years.
I tell every practice owner the same thing here, and almost all of them quote me the first-visit figure when I ask. It is usually wrong by a factor of ten, and it makes every advertising decision look worse than it is.
Work out your own: average annual spend per active client, multiplied by how many years they typically stay. That is your ceiling.
What the clicks cost
Veterinary search advertising is mid-priced compared with other local health categories. According to published industry benchmark data for 2026, cost-per-click on veterinary terms sits roughly between $2 and $8, with emergency and specialist terms running higher because the intent is immediate and the competition is thinner but more determined.
The spread inside that matters more than the average. “Vet near me” and “emergency vet open now” are different purchases. One is someone choosing a practice at leisure; the other is someone in a car with a distressed animal. The second converts several times better and costs more per click for good reason.
From click to client
The chain has three steps and each one loses people.
Clicks to enquiries: commonly 5 to 10 percent on a well-built page, far less on a slow or generic one.
Enquiries to booked appointments: this is almost entirely about how fast somebody answers. A practice that returns calls the same hour books far more than one that returns them the next day, and no advertising change compensates for that gap.
Booked to attended: usually high in veterinary, better than most health categories, because people who book for a pet turn up.
Multiply those and you get your real cost per new client. For most practices running competent campaigns it lands somewhere between $50 and $200. Set against a multi-year client value, that is a good trade. Set against a single first visit, it looks like a bad one, which is why the value calculation has to come first.
What management costs on top
Agencies charge either a percentage of ad spend, commonly 10 to 20 percent, or a flat monthly fee. The percentage model has an obvious problem: the agency earns more when you spend more, whether or not spending more is right for you.
I charge a flat fee, $800 per month to start and $1,500 for the core plan, billed monthly with no minimum term, and I take no percentage of ad spend. Your budget is your budget.
The three ways this money gets wasted
No conversion tracking. If nobody can say which ad produced which booking, the reporting is decoration. Ask to see it before you spend.
Bidding on your own practice name. People searching for you by name were already coming. Paying for that click buys a client you had.
Running ads to a slow website. The cheapest way to halve your cost per client is often to fix the page rather than change the campaign.
What I would do with a small budget
If you have $500 to $1,000 a month, do not spread it. Put it on the highest-intent searches in a tight radius around the practice, track calls properly, and answer the phone fast. Breadth is what you buy after the narrow version is provably working.
