Google Ads for Orthodontists: A Guide With Real Numbers

Every guide on this topic says the same three things: do keyword research, write compelling ads, track conversions. None of them show you a single dollar figure from a real account. So the practice owner reading them learns nothing about the only question that matters: what will a lead actually cost me — and how many of those leads book?

This guide comes from running orthodontic ads accounts directly. Below is how they’re structured, what the numbers look like — including a campaign that got killed this spring — and the mistakes that show up in nearly every audit.

First, the definition, because this industry cheats on it: when I say lead, I mean a phone call generated by the campaign or a completed consultation-request form. Not a click. Not a pageview. Not a “get directions” tap. If a vendor quotes you a cost per lead, make them define the word before you believe the number.

The honest summary up front: Google Ads is the fastest lead-producer available to an orthodontic practice — a well-structured account produces real leads in the $20–$50 range depending on campaign — and it’s also where practices burn more money than every other channel combined, because nobody is actually inside the account. The channel isn’t the variable. The operator is.

What the Numbers Look Like When It’s Built Right

Here’s the spread across a well-structured orthodontic account in a Midwest market — three campaigns, same practice, same months.

The geo-targeted local campaign is the workhorse. Tight radius around one office, the terms parents in that town actually use, a landing page built for the campaign rather than the homepage. Leads under $20, converting better than one click in five. A sibling campaign around a second market runs higher — different competitive density, same structure — and is still comfortably profitable.

The one I shut down: aligner-intent “near me.” Here’s the part every other guide leaves out, and it isn’t the lesson you’d expect. Compared against the braces-intent near-me campaign — same structure, same modifier, same quarter, only the treatment differs — the aligner campaign bought cheaper clicks and produced worse leads: less than half the conversion rate, and a cost per lead roughly double. That traffic is saturated with direct-to-consumer aligner shoppers comparing mail-order prices, not parents choosing an orthodontist. Cheap clicks, wrong buyers. I gave it a quarter of data and killed it. The lesson isn’t “near-me campaigns fail” — it’s that intent quality beats click price, and you can only see intent quality in the conversion column, never in the CPC column. The willingness to shut down a campaign — including your own build — is the difference between management and a retainer.

Branded defense is cheap insurance. Competitors can and do bid on your practice name; without a branded campaign, the top result for your own practice can be someone else’s ad. Check auction insights before you fund it, though — if nobody is actually bidding against you, you may be paying for clicks your organic listing would have caught for free.

And the structural point. Restructuring an account — killing a bloated broad top-of-funnel campaign and rebuilding around local intent — can cut blended cost per lead by half on essentially flat spend. The mechanism isn’t budget. Structure decides outcomes, not spend.

How an Orthodontic Ads Account Should Be Built

Campaign architecture

Separate campaigns by intent and economics, not by Google’s defaults: a core local-search campaign (your money-maker), a branded defense campaign, optionally treatment-specific campaigns — knowing that braces terms and aligner terms behave like different species, as the shutdown above proves — and Performance Max only after search is stable, never instead of it. One blended “leads” campaign is how budgets disappear without a story.

The landing page is half the campaign

Sending ad clicks to your homepage is paying for traffic and then misplacing it. The campaign landing page needs: the offer matching the ad, scheduling above the fold, the doctor’s face, financing addressed, and nothing else to click.

Negative keywords are a weekly job, not a setup task

The search-terms report is where the money leaks. Without maintenance you will pay for clicks from job seekers, dental-school students, DIY-aligner shoppers, and clinical terms for conditions the practice doesn’t even treat. Weekly search-term review is unglamorous and worth more than any bidding strategy.

Conversion tracking that counts leads, not activity

Phone calls and consultation-request forms as primary conversion actions — nothing else. The most common corruption I find in audited accounts: page views, “get directions” taps, and duplicate form goals counted as conversions, which makes every CPA in the account a fiction and every automated bid decision confidently wrong in the same direction. Set calls and real forms as primary, demote everything else to observation, and reconcile monthly against the front desk’s booking log so lead counts become consultation counts.

What Should the Budget Be?

Start: $1,500–$3,000/month in ad spend for a single-location Midwest practice, expecting the first 30 days to buy data, not leads. At stable performance, scale by the only rule that matters: if cost per lead is profitable against your case math and booking rate, the budget ceiling is your chair capacity, not a percentage. One concrete flag: it’s common to find a campaign producing profitable leads while declining half its available impressions to a budget cap. That’s demand turned away at the door — the most common invisible mistake in small accounts. One exception: on a branded campaign, lost impression share is a weaker signal, since those searchers may reach you through your organic listing anyway.

What it costs in clicks: local orthodontic CPCs in Midwest markets generally run in the mid single digits to high single digits, varying with competitive density. And a finding that contradicts the standard advice: aligner-term clicks aren’t the expensive part — the DTC aligner wars haven’t inflated the clicks so much as contaminated the intent behind them. Judge aligner campaigns on conversion rate, not click price.

The Five Mistakes in Almost Every Audited Account

• Nobody is in the account. Set up once — often by a previous vendor — then untouched for months while “management fees” accrue. The search-terms report tells the story in thirty seconds.
• Broad match + Smart bidding with thin conversion data. Google’s automation needs volume to learn; a single practice rarely has it. Automation on bad data automates the badness. (The bloated top-of-funnel campaign I killed was exactly this.)
• Homepage as landing page. The most expensive lazy decision in the account.
• No branded campaign — while a competitor (or a DSO with a real budget) quietly buys the practice’s name.
• Conversion actions counting activity instead of leads — page views and direction-taps inflating “results” while the real number hides. If your vendor’s report says “conversions,” ask what a conversion is.

If your current vendor runs your ads: ask for last month’s search-terms report and your cost per lead — with lead defined. Those two artifacts tell you everything about whether anyone is actually working.
