What This Google Ads Case Study for Local Services Reveals
This Google Ads case study for local services shows how structural optimization can dramatically improve conversion performance without increasing budget.
The client had three clear objectives:
Increase qualified phone calls
Maintain a stable CPA
Improve geo efficiency
Properly structure Search and Performance Max campaigns
In short: higher-quality leads, not just more traffic.
What We Changed
Instead of touching budgets first, we focused on structure and intent.
Here’s what was implemented:
1. Separated Search and Performance Max by intent
Search campaigns were rebuilt around bottom-of-funnel keywords, while Performance Max was positioned as a supporting layer — not a catch-all traffic source.
This alone improved control over lead quality.
2. Applied +5% bid adjustments on priority radius zones
We identified the highest-performing geo areas and applied positive bid adjustments only where conversions actually happened.
No guesswork. Pure geo efficiency.
3. Cleaned traffic using negative keywords
Search term mining revealed irrelevant queries leaking spend.
We aggressively filtered traffic to protect CPA and improve intent.
4. Optimized around phone call conversions
Instead of optimizing for generic conversions, we prioritized qualified phone calls as the primary success metric.
Reallocated budget to top-performing segments
Budget was shifted away from underperforming areas and campaigns into proven zones and BOFU Search.

In just 14 days, I increased conversions from ~28 to ~59 while reducing cost per conversion from ~$32 to $15.83 — a 50% CPA drop — without increasing overall spend. Qualified phone calls also increased to 51, confirming that growth came from structural improvements rather than budget increases.
Why It Worked
Growth didn’t come from increasing budget.
It came from:
Intent segmentation
Geo bid control
Conversion prioritization
Traffic quality filtering
In other words:
Structure beats budget increases.
This is the difference between “running ads” and operating a growth system.
What Comes Next (Scaling Plan)
With the foundation in place, the next phase focuses on:
Expanding high-performing radius zones
Scaling BOFU Search campaigns
Layering remarketing into Performance Max
Continuing query mining for efficiency
This creates a repeatable scaling framework without sacrificing CPA.
Final Thoughts
Most local service accounts struggle not because of budget limits —but because of poor structure, weak intent signals, and uncontrolled traffic.
Fix those first — and performance usually follows.
