A mother searches for an orthodontist on her phone during her daughter's soccer practice, taps your ad and fills in the request form. Two days later your front desk calls her back and books an exam. The exam happens the following week, records are taken, and the treatment coordinator walks the family through a plan. Ten days after that, the contract is signed with a down payment, and your practice software logs the case.
Google Ads saw the tap. If you're lucky, it saw the form. It never heard about the exam, the records or the signature, so as far as your ad account knows, that click produced one form fill, worth exactly as much as the form a curious adult abandoned halfway through.
This chapter wires the account so it hears the whole story before any keyword goes live. Our examples come from 12 orthodontic practices in one example market, Detroit, each found running Search ads in Google's Ads Transparency Center. Your market will have different practices and different numbers. The method is the same anywhere in the US.
A Free Consult Is a Lead. A Signed Contract Is the Sale.
In Google Ads, a conversion is any action you tell the account to count. That sounds like bookkeeping, and it isn't. Once an action counts, Google's bidding starts hunting for more people who look like the ones who did it. Your conversion list is a report card for you and a shopping list for the algorithm at the same time.
For an orthodontic practice, the steps from ad to case are easy to name. Someone calls, sends a form or books online. They keep the exam. The practice takes records. The family or the adult patient signs a treatment contract, and treatment starts. Each step is worth more than the one before it, and plenty of people stop along the way. In the AAO's own economics survey, 64% of new patient exams became treatment starts in 2024. A booked exam and a signed contract are not the same event, and an account that counts them as equals is learning from a blurry photo.
The method in this guide launches with Isolation, a BrandRocket name, not a Google setting: exact match keywords, with bids set by a person, on the searches you already know book exams. Exploration, also our name, arrives once the account has proof: broad match plus Google's automated bidding, roaming into wordings like "is it too late for braces at 40" that no keyword list would include. Isolation shrugs off a few weeks of messy tracking, since a person sets each bid by hand. Exploration has no such cushion. Its only compass is the conversion list.
That's also why an inherited account full of junk conversions is worse than an empty one. Page views counted as conversions, a "contact us" page load, a duplicate booking event: each one teaches Google to find more of the wrong people. Switch them off or demote them to secondary while the new campaigns are still paused.
A Phone Call, a Request Form and an Online Booking Are Three Conversions. Google Counts Only the Ones You Tag.
We went through all 12 example sites the way a parent would, stopping short of submitting anything. Every one showed a phone number. Six sent new patients to a scheduler or booking app with its own domain or subdomain: Ortho2 Edge, Doctible, Dolphin on two sites, a dental group's booking subdomain and an AI scheduler embedded from another company. Five took new patients through a request form only, followed by a callback. One showed a scheduler panel whose system we couldn't identify. Four offered texting.
We also opened each home page's source code looking for call tracking: a script that shows each visitor a different phone number, so the practice can tell which ad a ringing phone came from. Two of the 12 showed one, both CallRail. Google Tag Manager appeared on 11. That call-tracking count is a floor, because anything loaded later through Tag Manager doesn't show up in a page's raw code.
Start calls with Google's own call tracking. Google can count calls placed straight from an ad, plus calls to a forwarding number it swaps onto your website. You choose the minimum call length; Google's help pages don't state a default. Our standard is 30 seconds, because a parent leaving a voicemail at 7:40 on a school night is a real lead, not a wrong number. CallRail and CallTrackingMetrics are paid outside services; they add things like recorded conversations and a source label for every caller. Some practices find them worth the monthly fee. This method doesn't require them.
Forms are simpler, with one catch. Count the thank-you message or confirmation page, never the form page itself. If your scheduler lives on another domain, the visit crosses from your site to the vendor's, and the ad click can get lost on the way. Cross-domain measurement in Google Analytics links the two, and you test it before launch.
Finally, the count setting. Google's own guidance says a business tracking leads usually wants one unique lead per ad click, since a second form from the same person adds nothing. Check every lead action and set it to "one." A parent who calls, then fills in the form, then books online is one family, not three.
Orthodontic Software Books the Exam. None of the 11 Tools We Checked Documents Sending the Contract Back.
The signed contract lives in your practice software. So we read the public documentation for the tools orthodontists use to run a practice, book new patients and hold virtual consults: Dolphin, OrthoTrac, Ortho2 Edge, Gaidge, OrthoFi, OrthoBanc, SmileSnap, Rhinogram, DentalMonitoring, Invisalign's SmileView and Cloud 9.
None of the 11 documents importing conversions into Google Ads or capturing the Google click ID with a new patient's record. Cloud 9's practice marketing product goes furthest, with a stated Google Analytics integration and support for UTM tags, which tell you which campaign a visitor came from. That's useful for reporting. It doesn't send a signed contract to Google Ads.
The practice software knows exactly which consult turned into a case and what the contract was worth. None of these tools documents a way to tell Google.
So the practice builds the bridge. With auto-tagging on, Google adds a click ID to the landing page address every time someone clicks an ad. A hidden field on your request form, or a Tag Manager variable passed to your scheduler, catches that ID and stores it with the new patient's record. When the contract is signed, someone at the practice, or a scheduled export, sends Google that click ID with the contract's value. Google recommends its Google tag for site-wide measurement and, where a practice runs both the tag and Tag Manager, consolidating into Tag Manager. That's where the click ID capture belongs too.
Health Privacy Rules Rule Out Enhanced Conversions. The Click ID Still Carries the Signed Contract Back to Google.
Most businesses would close this loop with enhanced conversions for leads, Google's tool for matching hashed emails and phone numbers from your records to ad clicks. Orthodontic practices can't. Orthodontic treatment is a medical service, aligners are FDA-regulated medical devices, and Google's customer data policy lists purchases of medical services and medical devices among its sensitive categories. Read the policy's opening and you'll find the four tools it covers: both flavors of enhanced conversions, uploads of store sales, and audiences Google builds from people who engaged with you.
Two more doors are shut for health care. Google's appointment booking goal isn't allowed in healthcare campaigns, even when the option appears in your account. And the recording feature Google uses to let its AI grade phone leads stays off for any business it classifies as health care, which leaves your minimum call length to separate real leads from wrong numbers.
What stays open is the import by click ID. It sends Google the click ID, the conversion's name, the time and its value, and nothing about the patient. Name the conversion something plain like "Contract signed," never a treatment or a condition. Two housekeeping notes: Google's help center tags the spreadsheet version of this import as legacy, and as of June 15, 2026 programmatic uploads moved to a newer service called the Data Manager API. For a health practice that can't use enhanced conversions, the click ID is still the road back.
HIPAA sits on top of all this. HHS's guidance on tracking technologies still carries a banner noting that a federal court vacated part of it in June 2024, and HHS hasn't published newer guidance since. Public pages about braces are a lower-risk place for a tag than a scheduling flow, a smile-photo upload or a patient portal. Fire the conversion on a confirmation page with no health details on it, keep tags off the portal, and have counsel review your setup. This is not legal advice.
Google Stops Accepting the Sale 90 Days After the Click.
Google drops a click-ID import uploaded more than 90 days after the last ad click. For enhanced conversions for leads the limit is 63 days, though that tool is closed to health practices anyway. So timing decides which event you send.
The treatment start is the wrong event. A seven-year-old put on observation may not start for a year or more. A Phase I patient may not sign for Phase II until years later. In our experience the signed contract lands much sooner, and it carries the number that matters: what the case is worth. Practice-management vendor Gaidge reports average contract values above $5,450 across its client practices. Send the contract with its actual value, and upload at least weekly so nothing ages out.
Observation recalls and Phase II conversions are still revenue. They just belong in your practice's own reports, not in Google's bidding.
A second timer runs inside the account itself. Google calls it the conversion window: how long after the ad click a booking or contract still earns that click the credit. Out of the box it's 30 days. Most conversion sources let you stretch it to 90. A family that keeps an exam three weeks after the click and signs a month later needs a window long enough to cover the whole trip.
Only a Primary Conversion Teaches Google's Bidding. A Secondary Conversion Just Keeps Score.
Every conversion action is primary or secondary. Primary actions fill the Conversions column and steer bidding. Secondary actions are recorded, but bidding ignores them. Google's advice is to bid toward a single stage of the funnel, because asking one bid strategy to chase website visits and converted leads at the same time can be duplicative.
For a new orthodontic account, that usually means calls, forms and bookings are counted from day one, and early on they may be primary just to get signals flowing. The kept exam is a stronger signal, and the signed contract is the strongest, but a new practice may only sign a handful of contracts from ads in its first months. When contracts arrive steadily, make the signed contract primary and move the earlier steps to secondary, where they still show up in reports. Treat a tap on your email address or a downloaded new-patient packet as scorekeeping only.
Leave attribution on data-driven, Google's default for most actions. Google retired the older rule-based models, so there's nothing else worth choosing. Then test everything. Call the tracking number from your own phone and stay on past your minimum length. Submit the form. Book a test exam in the scheduler. By the next day, each test should show up exactly once, under the action you meant. If one doesn't, Google's Tag Assistant shows which pages fired a tag and what data left with it.
An orthodontist who would rather hand off the wiring can see what our Google Ads management covers.
Next: Someone Searching "Overbite" Is Reading Up. Chapter 2 Starts With the Searches That Pick a Practice.
With calls, forms and bookings counted once and the signed contract on its way back, Google can finally tell an exam that turns into a case from one that doesn't. Chapter 2 separates the parent reading about overbites from the one comparing orthodontists nearby, and puts a new account's first dollars on the second.
This chapter is part of Google Ads for Orthodontists, our sixteen-chapter guide for orthodontic practices anywhere in the US.
