A person who needs a new knee usually knows it. They've had the X-rays, the injections and the talk with their primary care doctor, and when they finally open Google they type something short and plain: "knee replacement surgery," "total knee replacement," "hip replacement surgeon." Thousands of people type those same few words every month.
A person who just hurt their knee types whatever comes out. "Knee popped playing pickleball now swollen." "Can't straighten leg after twisting it." "Torn meniscus doctor that takes my insurance." Nobody could write those searches down in advance, and nobody ever will, because tomorrow somebody will think up a new one.
Both people may end up on your surgery schedule. They just have to be bought in a different way, and in a different order.
Some Orthopedic Searches Fit on an Index Card. Most Can't Be Written Down at All.
The keyword list we built in Chapter 5 shows both kinds side by side. In our example market, Nashville, procedure searches bunch up at the top. Only 44 procedure phrasings reached 100 or more searches a month, and most of those were the same few searches reworded. "Knee replacement surgery," "knee replacement operation," "surgical knee replacement" and "tkr knee surgery" all showed exactly 480 a month, because Keyword Planner reports close wordings as one search wearing different clothes. "Total knee replacement," "full knee replacement" and "complete knee replacement" all sat at 320. Hip replacement had its own short stack, led by "hip joint replacement surgery" at 390. Shoulder, spine and hand each had a handful more.
That's the index card: a few dozen procedure and specialist searches, typed the same way by thousands of people, with a volume you can look up before you spend a dollar.
The injury side looks nothing like it. Just the knee, ACL and meniscus part of the list held 1,576 different phrasings, and Keyword Planner barely scratches the symptom searches. It only reports searches with enough volume to measure. In the whole example list, 155 ideas described an injury or a symptom, and plain "knee pain" didn't return a row at all. The real injury searches only show up once ads are running, one odd phrasing at a time, in the search terms report.
Google has said as much about search in general: 15 percent of the searches it sees every day are ones it has never seen before. Orthopedics gets its share of that 15 percent every time somebody lands wrong on a trampoline.
Exact Match Covers "Knee Replacement Surgery" and Five Other Ways to Type It
The first campaign in a new orthopedic account goes after the index card. We call it Isolation. Google has no such label; it's ours. In practice it's a Search campaign where every keyword on the card is exact match, and the practice decides each price. The ad groups follow the body-part layout from Chapter 4: knees in one, hips in another, shoulders in a third.
Exact match no longer means the search has to be typed letter for letter. Google's help page for match types describes exact match in terms of meaning and intent now, not spelling. So a single exact keyword built on the most common wording of a knee replacement search reaches the operation and op versions, and the "tkr" shorthand too. You don't need a keyword for every wording on the card, and you don't need to chase the misspellings.
What you do get is control. Every search in Isolation is one you picked on purpose. The ad that answers "total knee replacement" talks about total knee replacement and sends the click to your knee replacement page. The bid on that ad group reflects what a knee patient is worth to your practice, not what a random "orthopedic doctor" click is worth. And when the numbers come in, you know exactly which search produced which consult.
Bid higher than feels comfortable at the start. On launch day the account has no track record at all. Your knee ad hasn't earned a single click yet, so it competes on price alone against orthopedic groups that have run ads in your city for years, and a cautious first-week bid tends to land somewhere below the fold. As your ads collect clicks and your pages prove they match the search, Quality Score builds and you can ease the bids down. Chapter 7 covers how to read the numbers that tell you when.
Keep broad match out of this campaign entirely. Isolation only works if every keyword in it is one you chose, and a single broad keyword left in by accident turns the campaign into a smaller, less careful version of Exploration.
Isolation's other job is to teach. Every booked consult it produces is a data point Google can learn from: this search, this ad, this page, this patient. That data is what the second campaign runs on.
Exploration Goes Looking for the Searches Nobody Would Think to Type
The second campaign goes after everything that isn't on the card. We call it Exploration, also our name. Build it by duplicating Isolation and cutting it down to the 3-5 keywords with the best booking record. Those few keywords go in as broad match. Bidding moves to Google's Maximize Conversions, and a target cost per acquisition caps what it may pay for each new patient.
On broad match, Google reads your keyword as a topic rather than a phrase, so an injury search can trigger your ad without using any of your keyword's words. Seed it with "torn meniscus surgeon" and it can find "knee locked up after squatting," "can't bend knee after soccer" and a thousand phrasings that will only exist next Tuesday. The target cost per acquisition tells Google how much you're willing to pay for each booked consult, so it can chase the odd searches without chasing them at any price.
This is where orthopedic accounts actually grow. Isolation is capped by how many people type the few searches on the card. Exploration isn't, because the long tail of injuries, symptoms and half-remembered diagnoses is far bigger than the card will ever be. In most accounts that run long enough, Exploration ends up carrying more of the volume than Isolation does.
Why Joint Replacement Goes Live Before "My Knee Clicks When I Squat"
If the long tail is where the volume is, why not start there? Because broad match with automated bidding is a guess until it has something to learn from.
Maximize Conversions looks at who booked in the past and hunts for more people like them. Launch it on day one, in an account with no booked consults, and it has nothing to go on. It will spend your budget learning, and a lot of that learning happens on searches like "knee pain exercises," "is my knee sprained or torn" and "orthopedic surgeon salary." Google isn't being careless. It simply hasn't seen a single patient book yet, so it can't tell a researcher from a patient.
Isolation fixes that first. It sends paid clicks only to searches you already know book consults, and every booking becomes training data. Exploration launches when there's enough of that data to aim with. The gate we look for is about 30 quality conversions a month: booked new-patient consults and real calls, not page views or brochure downloads. For most practices that's usually a couple of months in. Bigger practices with bigger budgets get there sooner.
Starting on the long tail doesn't save time. It spends the first months of the budget teaching Google the wrong lesson.
Inside Out: The Known Searches Protect the Unknown Ones
Once both campaigns are running, the account works from the inside out. At the center, Isolation keeps the index card: the procedure searches you've already seen turn into consults, each at a price the practice chose. Exploration works the space around it.
Google gives the search to Isolation first. When somebody types a search identical to one of your exact match keywords, Google prefers the exact keyword over a broad one, so "knee replacement surgery" still goes to your knee ad group at your bid, not to Exploration's automated bidding. That keeps the heart of the account steady while Exploration takes chances around the edges.
The two campaigns also feed each other. When Exploration keeps booking consults from a search you never thought of, say "meniscus tear surgeon near me," that search moves into Isolation as a new exact keyword with its own bid. Over time the card gets longer, one proven search at a time.
The balance shifts as the account matures. Once Exploration is carrying the account reliably, some practices pause Isolation and let the broad campaign handle everything. Isolation isn't gone for good. If you start losing position on a search that matters, like your highest-value procedure, you can turn Isolation back on and reclaim it.
The First Month of Exploration Is a Daily Job
Broad match earns its reach by guessing, and early on some of those guesses are wrong. In an orthopedic account, the search terms report during the first weeks of Exploration usually looks something like this: a few real patients looking for help with a torn ACL or a shoulder that won't lift, next to people requesting their medical records, looking up a workers' comp form, searching a surgeon's name from another group, pricing a knee brace on Amazon or trying to find an orthopedic surgeon for their dog.
None of that is a reason to switch broad match off. It's a reason to read the report every day for the first 30 days. Each morning:
- Add the strays to the shared negative lists from Chapter 5: competitor and surgeon names to the names list, records, jobs and do-it-yourself searches to the second list.
- Flag the searches that booked consults. The ones that keep booking are candidates to move into Isolation.
- Watch the cost per booked consult against your target, not just the click count.
After the first month the junk slows down, because Google is learning from what books and your negative lists have caught the regular offenders. The review drops to weekly. It never stops completely. People will keep inventing new ways to describe a bad knee.
Next: The Knee Replacement Ad Group Gets a Different Bid Than "Orthopedic Near Me"
You now have both campaigns in the right order: the short list on exact match first, the long tail on broad match once the account has earned it. Chapter 7 covers the money side: how to set each Isolation ad group's bid on what its patients are worth, and why a knee replacement click and an "orthopedic near me" click shouldn't cost the same.
The guide home has the full sequence.
For orthopedic groups that hand us their Google Ads management, Exploration doesn't launch until Isolation has earned it, and the search terms get read every morning while it learns.
