Ask an orthodontist to list the searches that bring in new patients and you'll get a short, confident list. Braces near me. Invisalign near me. Orthodontist plus the town. Pediatric orthodontist. The practice's own name. All correct, and all incomplete.
Now look at what people actually type on the way to booking. "Can I pay $100 a month for braces?" "Is 35 too old for Invisalign?" "Is $5000 a good price for braces?" Nobody puts those on a keyword list, and plenty of the people typing them are a week away from an exam.
This chapter is about both kinds of searches: the short list you can name today and the long tail you can't, and how an orthodontic account reaches each one without paying to learn the same lesson twice. The examples come from Google's results pages in one example market, Detroit, and from Keyword Planner across the US. Your market's wording will vary. The method won't.
Exact Match Buys the Orthodontic Searches You Already Know. Broad Match Finds the Questions Nobody Would List.
Our method works from the inside out. The inside is the searches you can name and already trust. The outside is everything around them.
The inside belongs to Isolation, the name we give the first campaign: exact match keywords only, with a person setting every bid. It holds the predictable, high-intent searches, the ones that name a treatment and a place or the practice itself. You know what they mean, you know roughly what they cost, and you want to show up for them every time.
The outside belongs to Exploration, our name for the second campaign: broad match keywords with Google's automated bidding. It goes after the long tail, the thousands of specific, oddly worded searches from people who are close to booking but would never type your neat keyword. That outer pool is far bigger than the inner one, and it's where an account grows once the inside is working.
Half the Questions Google Showed Under Orthodontic Searches Were About Money.
Google's results pages give away what people want to know. Under most searches there's a box of related questions, labeled "People also ask," built from what other searchers typed.
We saved Google's results for 22 orthodontic searches run from Detroit, our example market. That box appeared on 21 of them, holding 84 question slots in all, 65 of them distinct. 41 of the 84 were about price or paying: "Can I pay $100 a month for braces?" showed up under four different searches, "Is $5000 a good price for braces?" under three. Twelve were about age, from "Is 7 years old too early for braces?" to "Is 35 too old for Invisalign?" Seven were about insurance, Medicaid or free braces.
The age questions show why the long tail can't share one ad. They run from a parent asking whether seven is too early for braces to an adult asking whether thirty-five is too late for Invisalign. Same topic, opposite buyers. When Exploration copies Isolation, it keeps the treatment ad groups from Chapter 4, so a question about a seven-year-old lands in the children's group with an ad and page written for parents, and a question about turning forty lands in the adult group. Broad match decides which searches to enter. The ad group structure decides what those searchers see when they arrive. Get the structure right and the long tail inherits it; get it wrong and every question gets the same generic ad, which is how a perfectly good click on a $5,000 decision turns into a bounce.
Read those questions as a portrait of the person behind them. They aren't idle. Someone asking whether $5,000 is a fair price for braces has a quote in hand. Someone asking whether 35 is too old for Invisalign has been thinking about it for years. These are the long tail, and they sound almost nothing like a practice's keyword list.
"How Long Does Invisalign Take" Gets 5,400 Searches a Month. "Is 35 Too Old for Invisalign" Shows No Data at All.
Some of these questions are big. Nationally, "how long does invisalign take" draws roughly 5,400 searches a month and "how long do braces take" about 2,900. Advertisers' top-of-page bids on them reach $15.00 and $28.02. Others don't register: Keyword Planner shows no data for "is 35 too old for invisalign," "braces at 40" or "can adults get braces," even though Google itself just showed the age questions on a results page.
That gap is exactly why the long tail can't be handled with a list. You can't add keywords you can't see, and the tool can't show you volume it doesn't report. Some of these questions are reading, a person months from treatment. Some are booking, a person comparing two quotes this week. There's no way to tell from the outside.
Exploration's job is to find out with real money and real bookings as the judge, instead of guesses.
It helps to see how lopsided the two pools are. The 12 example practices' sites gave Keyword Planner enough to suggest 6,663 distinct searches. A sensible launch list for Isolation is a few dozen of them. Everything else, thousands of phrasings about cost, timing, age, retainers and specific treatments, sits outside the list. About 450 of the suggested ideas were cost and price questions alone, and nearly 480 were about retainers. No practice should try to hand-bid that many phrases. That's the work broad match and automated bidding are built for, once they have something to learn from.
Broad Match and Automated Bidding Were Built to Run Together. That's Why Exploration Waits for 30 Conversions a Month.
Google's own help page on match types pairs the two. Broad match is the default every keyword starts with, and Google says its automated bidding learns best across broad match's wide net, competing only in the auctions it judges worth winning.
The catch is in the word "judges." Automated bidding decides what an auction is worth by looking at what has already turned into a booked exam or a signed contract in your account. With no history, it has nothing to aim at, and broad match with nothing to aim at is a credit card on a long leash.
Why only three to five keywords? Because broad match turns each keyword into a doorway to hundreds of related searches. Seed it with thirty and the campaign spreads thin before the bidding has learned anything. Seed it with the few that have already booked exams, and every related search it explores starts from a phrase with a track record. More keywords can join once the first ones prove the campaign is finding patients, not just traffic.
So Exploration waits. On launch day, Exploration copies Isolation's structure but keeps only its proven performers, typically three to five orthodontic keywords that already produced booked exams. Those keywords run on broad match, and the bidding chases conversions at a cost per booked exam borrowed from what Isolation actually achieved. For a typical practice that's around month two or three. The calendar is only a guide. Exploration opens when the account is logging around 30 quality conversions a month, and a large orthodontic group can cross that line in its first weeks.
The Search Terms Report Is the Only Place an Orthodontist Sees the Questions It Paid For.
Once Exploration is running, there's one report that matters more than any other. Every Google Ads account keeps a list of the exact words people typed before your ad appeared. Google calls it the search terms report. Google only includes searches that enough people typed, and drops rare ones to protect searchers' privacy, so the list is never complete. It's still the only window into what broad match bought.
During Exploration's first month, someone on the team reads it every single day. Every search on it gets one of two fates.
The hard part is telling them apart, because orthodontic questions blur the line between reading and buying. Our rule of thumb is to judge a search by what happened after the click, not by how it sounds. "How long do braces take" sounds like research, but if it keeps producing booked exams in your account, it's buying. "Free braces for adults" sounds like a lead, but if every click ends in a hang-up or a bounce, it's not. Give a new search a few days and a handful of clicks before deciding, unless it's plainly off-topic, like a job posting or a mail-order brand, which can be blocked on sight.
A question that turns into booked exams graduates: it becomes an exact keyword in Isolation, with a bid a person sets and an ad written for it. If it doesn't, because it's a mail-order brand, a job seeker or a question from someone years away, it goes on the negative list from Chapter 5. Over a few weeks the list of questions you understand gets longer, and the list of searches you'll never pay for again does too.
This Quarter's Broad Match Find Becomes Next Quarter's Exact Match Keyword.
Isolation and Exploration aren't stages you pass through. They're two campaigns that keep trading weight.
Early on, Isolation carries the account. Later, as Exploration learns, it often carries most of the bookings, and Isolation can be paused. But not forever. When a particular search matters, the practice's own name or "pediatric orthodontist near me," and Exploration stops winning the top of the page for it, Isolation comes back on to reclaim that spot. The balance shifts with the data, not the calendar.
A practice that runs this loop for a year ends up with an exact keyword list no competitor could copy from Keyword Planner, because it was written by its own patients' questions. That loop is the engine of the whole method: the long tail finds the questions, the report sorts them, and the best ones come back inside where you can bid on them by hand.
An orthodontist who would rather have that loop run for them can see what our Google Ads management covers.
Next: The Top Bid for "Invisalign Consultation Near Me" Is Five Times the Top Bid for "Invisalign." Chapter 7 Sets Bids Ad Group by Ad Group.
You know which searches belong inside and which wait for Exploration. Chapter 5 built the starting list. Chapter 7 turns the value from Chapter 3 into actual bids, one ad group at a time.
