Google Ads for Dentists
We've audited dental Google Ads accounts ranging from solo practices to multi-location groups. The waste patterns repeat. Here are the five most expensive mistakes — and what to do instead.
By Stephen Theall
1. One campaign for the whole practice
Cosmetic, cleanings, emergency, implants, and ortho all running out of a single campaign means your $5,000 implant lead is competing with your $30 cleaning lead for the same daily budget. Quality Score craters because the ad copy can't match every service. The campaign ends up serving the cheapest converters and starving everything else.
Fix
Split into one campaign per service line — emergency, general/cleanings, cosmetic, implants, ortho. Each gets its own budget, its own landing page, its own bid strategy. Emergency keywords get day-parted bid increases during business hours. Cosmetic gets remarketing. Cleanings get a tight geo-radius.
2. No phone-call conversion tracking
Most dental leads are phone calls — especially emergencies and new-patient inquiries. If you only track form fills, you're seeing maybe 30% of the conversions Google Ads actually produced. The owner then says 'Google Ads doesn't work' while the front desk is fielding 30 ad-driven calls a month nobody's counting.
Fix
Turn on call tracking from both the ad (Google's call forwarding number with a 60-second minimum duration) and the website (dynamic number insertion via CallRail, CallTrackingMetrics, or WhatConverts). Set the call as a conversion action so Smart Bidding can learn from it.
3. No insurance keyword targeting
Patients searching 'dentist that takes Delta' or 'Cigna PPO dentist near me' are already pre-qualified — they've checked their insurance and they're shopping carriers you accept. These convert at 2-3x the rate of generic 'dentist near me' searches. Most practices never build an insurance ad group.
Fix
Create a dedicated ad group for each major insurance plan you accept. Match the keyword to ad copy that names the plan ('We accept Delta Dental PPO'). Land them on a page that lists your accepted insurances above the fold with a click-to-call number.
4. Targeting a 50-mile radius 'to capture everyone'
Nobody drives 50 miles for a cleaning. They might for an implant specialist, but your routine-care campaigns shouldn't be paying for clicks from people who'll never show up. A wide radius inflates your cost-per-conversion 2-3x because half your spend goes to clicks that physically can't convert.
Fix
Set a 10-15 mile radius around the office for routine campaigns, with bid adjustments that boost the 5-mile core. High-LTV procedures (implants, full-arch, ortho) can run a wider radius — they justify the longer drive. Tighter geo on emergency campaigns too: people in pain go to the closest open door.
5. Letting Google auto-apply recommendations
The Recommendations tab quietly turns on broad match keyword expansion, enables Search Partners, and shifts budget to whatever Google thinks 'should' work. For dental, that means your 'emergency dentist Lafayette' campaign starts matching 'dental hygiene salary' and 'how to extract a tooth at home.' This is the single most common $500-2,000/month waste source we find.
Fix
Turn off auto-apply in Account Settings. Review recommendations manually once a week. The good ones (ad strength improvements, missing extensions) take 30 seconds to apply. The bad ones (broad match expansion, budget moves, Search Partners) you ignore. We tell you which is which in plain English in our audit.
The dental-Google-Ads playbook in one paragraph
Dental is one of the easier verticals to get right on Google Ads, but it punishes lazy setups. The economics work because a new patient is worth $300-$2,000 lifetime depending on the procedure mix, and a Lafayette-to-Lake-Charles solo practice can run profitable Search ads on a few hundred dollars a week. What kills accounts is treating it like e-commerce: one big campaign, broad keywords, Smart Bidding turned on at signup, no call tracking. The accounts that work treat each service line like its own business — emergency is a different audience than ortho, and the ad copy, landing page, and bidding need to reflect that.
Conversion benchmarks worth knowing
Industry data (WordStream 2024, LocaliQ 2024) puts dental Search at roughly a 10% conversion rate, $8-9 average CPC, and a $75-90 cost-per-acquisition for general dentistry. Cosmetic and Invisalign run higher CPCs ($15-25) but justify them through higher patient value. Implants and full-arch ($100-400 CPL) sit at the top end. If your account is reporting CPAs more than 50% above these numbers, something is broken — usually one of the five mistakes above.
The high-value channel most practices haven’t enrolled in
Local Service Ads (the green “Google Screened” listings that appear above the regular paid ads) were rolled out to dental in 2023 in most US metros. Many practices still aren’t running them. LSA leads are pay-per-lead instead of pay-per-click, vetted by Google, and routinely 30% cheaper per booked patient than Search in the same market. If your practice qualifies and you haven’t enrolled, that’s usually the single biggest opportunity in the account.
