Industry
Pest Control Services
Service Focus:
Local Pay-Per-Click (PPC) / Google Ads Management
Campaign Period:
12 Months
The Challenge: High Spend, Low Return in a Competitive Local Market
A well-established regional pest control company had been investing heavily in Google Ads for years, but their return on ad spend was severely underperforming. Despite a healthy monthly budget, the campaign suffered from a poorly structured account architecture that resulted in wasted spend on irrelevant clicks, bloated Cost Per Lead (CPL), and a lead volume that had plateaued far below the company’s growth targets.
At the time of our engagement, the client was paying $91 per lead, an unsustainable acquisition cost that was eroding the profitability of every job booked through paid search. They were generating roughly 15 leads per month from their Google Ads investment, a volume that could not justify the spend or support meaningful business growth.
They needed more than a campaign tweak. They needed a complete overhaul of their paid search strategy, one that would stop the financial bleeding, eliminate wasted ad spend, and rebuild the account from the ground up as a scalable, profitable lead generation engine.
The Strategy: Granular Targeting and Bidding Optimization
To rescue the campaign and drive profitable growth, we executed a full teardown and rebuild of the Google Ads account. Our strategy was built around three core “needle-moving” tactics:
1. Robust Campaign Restructuring
The original account was structured too broadly, grouping dissimilar services and keyword intents into the same ad groups. This meant ad copy could not be tailored to specific user intent, resulting in poor Quality Scores, higher CPCs, and low conversion rates. We dismantled the old structure entirely and rebuilt it with highly granular ad groups dedicated to individual services, mosquito control, rodent removal, ladybug extermination, and more. Each ad group was paired with tightly matched, intent-specific ad copy designed to speak directly to what the user was searching for.
2. Enhanced Keyword Targeting and Negative Match Expansion
We audited the full search term report to identify where budget was being wasted on informational, non-commercial, and irrelevant queries. We then aggressively expanded the negative keyword list to immediately stop ad spend from bleeding into searches that would never convert. Simultaneously, we refined the positive keyword targeting to focus exclusively on high-intent, service-specific commercial queries, the searches made by people who have a pest problem and are ready to call someone today.
3. Complete Bidding Strategy Overhaul
The account had been running on a manual or click-focused bidding strategy that optimized for traffic rather than conversions. We transitioned the account to a conversion-focused smart bidding strategy, setting a target cost per acquisition (CPA) aligned with the client’s profitability thresholds. This ensured that every dollar of ad spend was directed toward generating a qualified phone call rather than simply driving website visits.
The Results: Exponential Lead Growth at a Fraction of the Cost
The impact of the campaign overhaul was immediate and transformative. Within the 12-month tracking period, the results demonstrated the power of precision paid search management.

Deep Dive: The Key Wins
Win 1: Slashing Cost-Per-Lead to Drive Profitability
The most critical objective was restoring the campaign’s profitability. By implementing strict negative keyword lists and transitioning to a conversion-focused bidding strategy, we eliminated the wasted clicks that were artificially inflating the client’s acquisition costs.
The result was a 59% reduction in Cost Per Lead, dropping from $91 to just $37. This drastic reduction in CPL meant the client could now acquire nearly two and a half customers for the price they previously paid for one, fundamentally changing the unit economics of their paid search channel and making Google Ads a genuinely profitable growth lever for the first time.
Win 2: Scaling Lead Volume to Record Highs
With a profitable CPL firmly established, the campaign was positioned to scale. In the most recent 30-day period tracked, the campaign generated over 100 high-quality leads, an increase of 85 leads compared to the client’s baseline performance from three years prior. This represents a 566% increase in monthly lead volume from the same ad investment.
This was not a short-term spike. Over the full 12-month campaign period, the Google Ads account drove 1,603 total phone calls, maintaining a consistent and growing flow of inbound opportunities. Call volume peaked at nearly 200 calls per month during the busy summer pest control season, demonstrating that the campaign had been built to scale with seasonal demand rather than against it.
Win 3: Delivering High-Intent, Qualified Conversations
Lead volume is only valuable if the leads are genuinely qualified. The granular ad group structure ensured that when users searched for specific pest problems, they were served highly relevant ads that matched their exact intent, driving them to pick up the phone with a specific problem in mind and a clear intent to book.
The quality of these leads is reflected directly in the call data:
77.2% of all calls, 1,237 out of 1,603 total, lasted longer than 60 seconds, indicating substantive, commercial conversations rather than misdials, wrong numbers, or quick hang-ups. The average duration of these qualified calls was 4.1 minutes, confirming that the campaign was consistently delivering prospects who were ready to discuss their pest issues in detail and move toward booking a service appointment.
The 98.3% call answer rate on the client’s end further demonstrates the quality of the lead pipeline, when the phone rang, the client’s team answered, because they knew the calls were worth taking.
By the Numbers: A 12-Month Snapshot
The table below summarizes the full campaign performance across the 12-month tracking period.
| Period | Total Calls | Qualified Calls (60s+) | Avg. Duration |
|---|---|---|---|
| Peak Month (Summer) | ~196 calls | ~151 qualified | 4.1 min |
| Full 12-Month Period | 1,603 calls | 1,237 qualified | 4.1 min |
| Qualification Rate | — | 77.2% | — |
The Power of Precision Paid Search
This case study demonstrates a principle that holds true across every local service industry: throwing more budget at a broken Google Ads account will never fix the underlying structural problems. The solution is precision, rebuilding the account with the right structure, the right keywords, the right negative lists, and the right bidding strategy.
By executing a complete account overhaul, we turned a failing, expensive paid search campaign into a highly profitable lead generation machine. The client now acquires leads at 59% less cost while generating more than six times the monthly lead volume they had before.
For businesses in competitive local service markets, pest control, home services, HVAC, plumbing, and beyond, this is the blueprint. Paid search done right does not just drive traffic. It drives revenue.
