Most orthodontic accounts set one bid and let it ride. A practice picks a number that feels reasonable, say $8 a click, and applies it to everything: braces, Invisalign, the kids' first visit, the practice name. It looks tidy. It also means the account pays the same for a parent comparing two orthodontists down the street as it does for someone idly typing a brand name on their lunch break.
Keyword Planner says those aren't the same searches, and the prices prove it. Nationally, advertisers' top-of-page bids for "invisalign" reach $10.99 at the high end. For "invisalign consultation near me" they reach $58.93, more than five times as much. Same treatment, same aligners, very different person on the other end. One is curious. The other is ready to sit in the chair.
This chapter turns the value from Chapter 3 into bids, one treatment at a time, then shows how to read whether those bids are winning. The examples come from Keyword Planner across the US and from one example market, Detroit. Your prices will differ. The way you set them won't.
Invisalign and Braces Are Two Different Auctions. One Account-Wide Bid Loses Both.
In the first campaign of our method, the one we call Isolation, nobody hands the bids to an algorithm. Google calls the setting Manual CPC: someone at the practice enters the most the account will pay for a click, and Google uses that number, together with ad quality, to decide whether the ad shows and where. The account usually pays less than the maximum. Google charges only what it takes to beat the next ad below.
The bids sit on the treatment ad groups from Chapter 4, not on the campaign, because each treatment carries its own value and walks into its own auction. In Detroit, Keyword Planner's top-of-page range for "orthodontist invisalign" runs $6.16 to $38.89. "Near me orthodontist" runs $5.19 to $32.12. "Braces near me" runs $3.92 to $24.29, and "pediatric orthodontist near me" $6.19 to $26.38. A single account-wide bid of $8 sits near the bottom of every one of those ranges. It would win a handful of cheap auctions and lose the ones where parents are actually choosing a practice.
So the Invisalign group gets its own number, the braces group its own, the children's group its own, and the practice name its own, which is usually the cheapest click in the account and the one you can least afford to lose. Within a group, a keyword that books noticeably better than its neighbors can carry a bid of its own. That's the whole structure. It takes an afternoon to set up and a few minutes a week to adjust.
A Booked Exam Worth $2,825 Can Carry a Click Far Above Keyword Planner's Range.
The first time a practice sees a $30 click, the instinct is to flinch. The math in Chapter 3 says otherwise.
Start with the ceiling. Chapter 3 walked a signed case back through the AAO's exam-to-start rate and a typical show rate to about $2,825 in expected contract value for each booked exam. The missing piece is how often a click from a parent or adult patient ends with an exam on the schedule. Nobody publishes a reliable one for orthodontic Google Ads, so we used 4% as a placeholder. At 4%, the account buys 25 clicks per booked exam, and $2,825 divided by 25 is about $113.
That's the most a click could cost before the average booked exam stops paying for its own advertising, and it's before the practice pays for brackets, aligners, staff or rent. Your real limit sits well below it. But look at where it sits compared with the market: roughly three times the top of the highest Detroit range above. Even at a gloomier 2% booking rate the ceiling is about $56, still above every Detroit range.
That headroom changes how a new account should behave. A brand-new orthodontic account has no history, and Google's quality ratings start from a blank chart. The cheapest way through that stretch is to bid toward the top of each range, win the top of the page, collect clicks and bookings, and let the account build a track record. As the keywords earn better quality ratings, the same position costs less, and the bids come down.
Top-of-Page Impression Share Counts the "Braces Near Me" Searches You Lost Before a Parent Saw You.
A bid is a guess until you check whether it's winning. Google keeps the score in a column called impression share: the impressions your ads received divided by the impressions they were eligible for. Eligibility depends on your targeting, your ads' approval status and their quality, so the column measures the auctions you could have entered, not every search on Earth.
Three versions of it matter for an orthodontist. Search top impression share: of the braces and Invisalign searches your ad qualified for, the share where it sat above the free listings. Absolute top is how often it held the very first spot. Then two columns say why you missed the rest. Rank losses mean the bid, the ad or the treatment page fell short in that auction. Budget losses mean the day's money was gone before a 4 p.m. parent got off work and searched.
For the practice name, "braces near me" and Invisalign, our target is showing above the organic results in 75 to 90 of every 100 auctions you qualify for. That range is BrandRocket's, not Google's, and the reasoning behind it is in our post on what impression share to aim for. Below it, competitors are meeting the parents you paid to attract. Above it, you're usually paying a premium for the last few auctions, which tend to be the most expensive ones.
Read the two lost columns before you touch a bid. If an ad group is losing to budget, raising its bid makes things worse: the money runs out sooner. If it's losing to rank, look at the keyword's Quality Score in the keywords view first. A score of 3 out of 10 on "invisalign near me" usually points to an ad or a page that doesn't match the search, and Chapter 4's one page per treatment is the cheaper fix. A higher bid on a weak ad is paying extra to show something parents skip.
Auction Insights Shows Who You're Bidding Against, Including Three Brands Under One Account.
Impression share says how often you showed. Auction insights says who showed with you. For each practice or brand that kept showing up beside you, Google's report gives two numbers worth reading first. Overlap rate is the share of your impressions where that rival's ad appeared too. Position above rate is the share of those shared moments when the rival sat higher. The report needs some volume to work: Google doesn't show insights when your impression share is under 10%.
In an orthodontic market, read the names carefully, because they aren't always separate businesses. In our example market, Google's ad transparency records show one national orthodontic group running two local practice brands and its own national site from a single ad account. In your auction insights, that can look like three competitors. It's one buyer with three storefronts, and when that buyer raises its bids, three of your rivals seem to get aggressive on the same afternoon.
That matters for the hardest call in bidding: when to stop. A group with three brands can afford to lose money on a search to keep its name in front of parents. A single-location practice can't. When one search's price climbs past what its treatment can carry, the right move is to step back from it and put the money into the searches where you win at a price that works. Chasing a group into an auction it's willing to lose money on doesn't prove anything about your practice. It just lowers your profit.
When Exploration Opens, Its Target Cost per Booked Exam Comes From What Hand Bidding Actually Paid.
Everything above builds the number the next campaign needs. When Exploration, our second campaign, opens with broad match and automated bidding, it runs on a target cost per booked exam. Google calls that setting Target CPA.
Google's own guidance points the same way. Once an account has booked exams on record, Google's help page on this setting suggests a starting figure: what each one cost, on average, over the past month. It also advises reading results over 30 days that hold 30 or more of them. Aim lower than reality and Google says you'll get fewer, because the bidding passes on parents who might have booked.
That's why Isolation comes first. By the time Exploration opens, the practice knows what a booked exam really costs on its own searches, set by a person, ad group by ad group. That number becomes Exploration's target. A guess from an industry average would only send the algorithm after a number that doesn't match your market. For most practices Exploration opens around month two or three. The calendar is only a guide: the real trigger is about 30 quality conversions a month, and a large orthodontic group can hit that much sooner.
A $4 Orthodontic Click That Ends in a Wrong-Number Call Booked Nothing.
A low cost per click is only good news if the calls behind it are real. Before raising or lowering any ad group's bid, listen to a sample of its calls, or read the front desk's notes on them.
Here's what to listen for in an orthodontic account. Someone wants a cleaning or a filling and doesn't know the difference between an orthodontist and a general dentist. Someone is chasing a refund from a mail-order aligner company. Someone wants to know if the practice is hiring. Each one shows up in the account as a click, and sometimes as a conversion, and each one makes the ad group look better than it is.
When an ad group is full of those calls, the fix isn't a higher bid. It's a tighter keyword list and the negative keywords from Chapter 5. Raise the bid only on groups whose calls end with an exam on the calendar. A $4 click that brings a wrong-number call cost $4 and booked nothing. A $30 click that brings a parent ready to book is the best deal in the account.
Do the same with the bookings that come through the website. If the Invisalign group's form fills rarely turn into exams on the calendar, its booking rate is lower than it looks, and so is the bid it can carry.
An orthodontic practice that would rather have someone set and check those bids every week can see what our Google Ads management includes.

The bids are set, and you know how to tell if they're winning. Chapter 8 turns to what the ads actually say, starting with what unhappy patients complain about in their reviews, which isn't what most orthodontic ads promise.
This chapter is part of Google Ads for Orthodontists, our sixteen-chapter guide for orthodontic practices anywhere in the US.
