Scaling Vet Ads Without Spending More
The Goal
Generate a steady flow of high-quality leads from Google Ads while keeping the cost per acquisition (CPA) below $20 and the total monthly budget under $1,500.
Challenges
Before we took over, the clinic was paying $50+ per lead, often for low-intent or irrelevant traffic.
Many users lived too far from the clinic, leading to a poor show-up rate and wasted calls.
On top of that, a large portion of the budget was being spent on spammy leads and cheap services that rarely converted into real appointments.
Our Strategy
We began by analyzing the results of the previous campaigns and ran an n-gram analysis to identify which keyword fragments were generating low-quality traffic.
Next, we traced the source of spam leads, most of them were coming from a Performance Max campaign. Based on that insight, we paused ineffective formats and rebuilt the entire campaign structure from scratch.
We created three separate standard search campaigns based on the clinic’s core services: surgery, dental care, and wellness plans. Each campaign was split into tightly themed ad groups with custom, high-quality ad copy.
To improve geographic relevance, we implemented ZIP-code-level targeting and excluded distant locations. This helped us focus only on users who were close enough to actually visit the clinic.
We also refined our negative keyword list, continuously filtering out irrelevant traffic. Over time, we brought the share of qualified, intent-driven traffic to 95–97%.
The new campaigns launched with a starting CPA already below the $20 target and we kept optimizing from there.
At first, we used a Maximize Clicks bidding strategy to collect conversion data as cost-efficiently as possible. This allowed us to identify more negative keywords without wasting budget. Then, we switched to Maximize Conversions with a $20 target CPA, and gradually reduced that target by 10–15% every few weeks. Over the course of 6 months, we brought the target CPA down to $9, while the actual CPA landed around $8, with consistently high lead quality.
Results Chart
The yellow line represents the number of leads (phone calls + online appointment bookings).
The green line shows the cost per lead (CPA).
As you can see, our structured optimization process steadily increased lead volume while consistently reducing CPA, proving the strategy worked without raising the budget.

Roughly 65–70% of leads scheduled a visit, and around 25-30% became repeat clients.
Insights
Scaling isn’t just about spending more, it’s about focusing smarter.
By segmenting services, tightening geographic reach, and aggressively filtering out junk traffic, we turned a high-cost, low-conversion account into a high-efficiency lead machine.
The real win? We didn’t just lower the cost, we increased lead quality, conversion rate, and client retention along the way.
If you’re running Google Ads for a veterinary clinic and want to improve your performance, here are a few key takeaways from this campaign:
Target the right age groups.
The highest-converting audiences were users aged 25–45, while the 55–65 segment performed the worst in both cost and engagement.

Mobile optimizaiton matters.
Over 70% of leads came from mobile devices, but due to a poorly optimized third-party scheduling tool, desktop traffic converted 4–5x better. If your mobile booking experience is weak, you’re leaving money on the table.

Run n-gram analysis regularly.
This technique helped us quickly identify underperforming search terms across all campaigns, saving time and budget by cutting waste before it scaled.

Never bundle all services into one campaign.
Each service should have its own campaign. Why? Because different services have different margins and target CPA thresholds, and lumping them together makes proper optimization nearly impossible.
Lower your target CPA gradually.
Once you have stable performance, reduce your tCPA by 10–15% every few weeks. Sharp cuts will usually break the algorithm, slow and steady wins the game.
