To a patient, a multi-specialty practice is one place. One name on the building, one phone number, one website, one parking lot. They might see a primary care doctor there this year and an orthopedic surgeon next year, and it all feels like the same practice.
To Google Ads, that practice is several businesses that happen to share a logo. Each service line has its own searches, its own price per click, its own value per patient, its own season, its own set of rules about what an ad can say and who it can reach. Run them as one campaign and Google treats them as one business, which means it quietly favors whichever line is cheapest to win, whether or not that's where the practice makes its money.
Every chapter in this guide has said "one campaign per service line" in passing. This chapter makes the full case, and shows how to build the account so the owner can still read it.
More Than a Quarter of Physicians Now Work in Multi-Specialty Practices
This isn't a niche problem. The American Medical Association's 2024 Physician Practice Benchmark Survey found that 27.8% of physicians work in multi-specialty practices, up from 22.1% in 2012. The share is higher in practices owned by hospitals, at 44.3%, but it's substantial among independent practices too: 20.5% of physicians in private practice work in a multi-specialty group.
Those groups are exactly the practices this guide was written for. They're large enough to advertise several service lines at once, and they're the ones most likely to have set up a single Google Ads campaign years ago with every service lumped together. Some of those accounts even look healthy at first glance, because the cheap lines produce plenty of bookings. The trouble only shows up when someone asks which specialty those bookings came from, and the account can't answer.
One Account, Five Price Lists
Chapter 3 walked through what a new patient is worth in different specialties. Put those numbers side by side inside one practice, and the problem with a single campaign becomes obvious.
Medicare pays about $118 for a new patient's first office visit. It pays the surgeon $1,159.35 for a total knee replacement, before the facility's share. A direct primary care membership might run $50 to $100 a month. A single IVF cycle can run $15,000 to $20,000. The cost of reaching a patient varies just as widely: Chapter 3's vendor averages ran from $18.54 per lead in dermatology to $141.17 in mental health, and Chapter 7 found top-of-page prices from under $4 for a cardiologist to over $38 for a therapist in our example market.
A campaign that mixes all of that has one budget and, eventually, one target. It can't aim for, say, $400 per surgical consult and $40 per urgent care visit at the same time. It spends where bookings are cheapest, and the expensive, valuable lines starve. Even a small line deserves its own campaign. A podiatry line with a few dozen searches a month can run its own Isolation campaign on a small budget; lumped in with urgent care, it would simply never get a turn.
Google Already Told Local Services Advertisers to Split by Specialty
Google has said as much about its own products. As Local Services Ads move into Performance Max, Google's help page for advertisers in more than one category is direct: "Google Ads doesn't support vertical-level Target CPA bidding." Its advice is to run separate campaigns for separate categories.
The same limit shapes every campaign type in this guide. Chapter 7 noted that Google doesn't recommend setting separate targets for individual ad groups. Chapter 10 showed that a sensitive service line and a non-sensitive one can't even use the same audience signals in Performance Max. Chapter 13 showed that AI Max's text guidelines are set per campaign. In every case, the campaign is the unit where a service line gets its own rules. A practice that wants each line to have its own target, its own audiences and its own guardrails has one practical option: give each line its own campaigns.
Each Service Line's Campaign Owns Six Decisions
Here's what each service line's campaigns should decide for themselves, and where in this guide each one comes from:
- Budget. Each line gets its own, sized to what its patients are worth (Chapter 3). A shared budget lets the cheapest clicks take the money.
- Conversion goal. Google lets a campaign override the account's default goals with its own. The orthopedic campaign counts orthopedic bookings; it shouldn't be optimizing toward the urgent care check-in button (Chapter 1). Each line's goal should be its own finished booking, not a softer action shared across the site.
- Bid target. Manual bids first, then a target cost per booking drawn from that line's own history (Chapter 7).
- Location. Urgent care draws from a few miles, orthopedics from the metro, a telehealth line from the states its clinicians are licensed in (Chapter 9).
- Ad copy voice. Each line's headlines come from what its own patients praise (Chapter 8).
- Sensitivity and text rules. Whether the line counts as sensitive for Google's health policy (Chapter 10), and its own exclusions and restrictions if AI Max is ever tested (Chapter 13).
Within each line, the structure from earlier chapters still applies: an Isolation campaign on exact match, an Exploration campaign on broad match when the line earns it, and later, Performance Max for that line. A five-line practice doesn't launch fifteen campaigns on day one. It launches Isolation for its readiest line, as Chapter 2 laid out, and adds lines and stages as each one proves itself.
The Practice Name Gets One Campaign. Each Doctor's Search Lands on Their Specialty.
Searches for the practice's own name are the cheapest bookings in the account, and they don't belong to any one service line. That's why the method this guide teaches puts the practice name and the doctors' names in a separate brand campaign from the start (Chapter 6), with its own small budget. Add the practice name as a negative keyword in the service-line campaigns, so those searches don't leak into the lines and make them look better than they are.
Inside the brand campaign, the doctors' names do something extra in a multi-specialty practice. Give each doctor, or each specialty's group of doctors, its own ad group, and send those searches to that doctor's specialty page or bio, not the home page. Someone searching an orthopedic surgeon's name plus "knee" is looking for that surgeon, and the page they land on should be about that surgeon and that knee, not a home page that makes them hunt through five specialties.
A doctor who works in two lines, such as a physician who sees both primary care and sports medicine patients, gets one ad group pointing to their bio page, which links to both services. The patient picks the door. Two more habits keep the brand campaign clean. If a doctor shares a common name with someone famous, or with another local doctor, add the city or the specialty to their keywords and block the searches that aren't about them. And when a doctor leaves the practice, pause their ad group the same day, so the practice isn't paying to send their former patients to a page that no longer lists them.
An Owner Who Can't Read the Campaign Names Never Sees Which Specialty Loses Money
The last piece is the one owners care about most: being able to look at the account and understand it. A multi-specialty account with twenty campaigns named "Search 1," "Search 2 copy" and "New campaign" is an account nobody can manage, least of all the person paying for it.
Name every campaign with the same three parts: the service line, the stage and the match type. A practice with several offices can add the location as a fourth part, since Chapter 9 gave each office its own radius. "Orthopedics / Isolation / Exact." "Orthopedics / Exploration / Broad." "Urgent care / Performance Max." "Brand / Practice and doctors." Listed alphabetically in the campaigns list, the account groups itself by service line, and anyone can see at a glance which lines are running and how far along each one is.
Then report the same way, line by line. Once a month, one page, one row per service line: what it spent, how many patients it booked, what each booked patient cost and how that compares with the line's target from Chapter 3. It fits on a single screen, and that single table answers the only question a practice owner really has about Google Ads: which parts are paying for themselves, and which aren't yet.
When a line consistently misses its target, the table shows it early, before it's drained a quarter's budget. When a line beats its target month after month, it's the one that earns more money next. That's the whole point of splitting the account. Each line gets judged on its own numbers, and the practice puts its money where the patients actually come from. Keep a short change log for each line as well: the date a bid moved, a budget changed or a new campaign launched. When the numbers shift next month, the log shows whether the account caused it or the market did.
For a line-by-line look at the pieces this chapter pulls together, revisit Chapter 3 on pricing a patient by specialty, Chapter 7 on manual bids and smart bidding and Chapter 10 on Performance Max without patient lists.
Next: The Service Lines Google Watches Most Closely
Some service lines carry far more risk than others. Chapter 15 covers pain management, weight loss and men's health: the stricter Google rules those lines play by, and why one violation in one line can put the whole account at risk.
Catch up on Chapter 13 on AI Max, or see every chapter on the guide home for Google Ads for Healthcare. When a practice hires us for Google Ads management, the account is built one service line at a time, and the monthly report reads the same way.
