Campaign Teardown: “Local Spark Electricians” Lead Generation
At PPC Growth Studio, we believe in showing, not just telling. That’s why I’m going to walk you through a recent campaign we ran for a fictional, but highly realistic, client: Local Spark Electricians, a service provider operating exclusively within the greater Atlanta metropolitan area. Our goal was clear: generate high-quality leads for residential electrical services. This wasn’t about brand awareness; it was about getting the phone to ring and forms filled. We knew we had to be incredibly precise, given the competitive nature of local service advertising.
Initial Strategy: Targeting Intent, Not Just Keywords
Our initial strategy focused heavily on capturing high-intent searches. We weren’t interested in someone vaguely searching “electrical services.” We wanted “emergency electrician Atlanta,” “ceiling fan installation Fulton County,” or “electrical panel upgrade Decatur.” This meant a deep dive into keyword research, moving beyond broad matches to exact and phrase matches wherever possible. We segmented campaigns not just by service type, but also by geographical areas within Atlanta, like Buckhead, Midtown, and Sandy Springs, recognizing that search behavior and competition could vary significantly even within a few miles.
We designed distinct ad groups for each core service: emergency repairs, installations, and upgrades. Each ad group contained highly specific keywords and ad copy tailored to that service. For instance, an ad group for “emergency electrical repair” would feature headlines like “24/7 Emergency Electrician” and “Fast Service Atlanta,” directly addressing the immediate need. This granular approach, though more time-consuming upfront, is non-negotiable for maximizing ROI in competitive local markets.
Creative Approach: Solving Problems, Not Just Selling Services
Our ad copy wasn’t just a list of services; it was about solving problems. We used headlines that spoke directly to common pain points: “Flickering Lights? We Can Help,” “Need a Panel Upgrade? Get a Free Quote.” We also incorporated trust signals, like “Licensed & Insured” and “5-Star Rated.” For call-only ads, which we heavily relied on for emergency services, the call to action was simple and direct: “Call Now for Immediate Service.” We utilized Responsive Search Ads, allowing Google’s AI to test various headline and description combinations, but we meticulously crafted a wide array of options to give the system quality material to work with. I’ve seen too many campaigns fail because marketers provide only three headlines and expect miracles. That’s just lazy, frankly.
Targeting & Budget Allocation
Budget: $15,000/month
Duration: 3 months
We geo-targeted specifically to a 20-mile radius around downtown Atlanta, excluding certain outlying areas known for lower average household incomes or higher competition that didn’t align with Local Spark’s typical client profile. Device targeting was initially broad, but with a slight bid adjustment favoring mobile, anticipating the immediate nature of many electrical issues. Ad scheduling was set to run 24/7 for emergency services, but primarily during business hours for scheduled installations and upgrades.
Our initial budget allocation was roughly 60% towards emergency services, 25% towards installations (e.g., lighting, ceiling fans), and 15% towards upgrades (e.g., panel upgrades, wiring). This was based on historical lead value data provided by Local Spark, indicating emergency calls, while sometimes lower ticket, often led to repeat business and referrals.
What Worked: Precision and Responsiveness
The hyper-focused keyword strategy paid dividends. Our Click-Through Rate (CTR) for emergency service campaigns averaged an impressive 8.7%, significantly higher than the industry average for local services, which often hovers around 3-5% according to a Statista report on Google Ads CTRs. This told us our ads were highly relevant to searcher intent. We saw a particularly strong performance from our call-only campaigns, which generated a Cost Per Lead (CPL) of $32.50 for emergency services.
Our ad extensions were also critical. We utilized call extensions, structured snippets highlighting specific services (e.g., “Outlet Repair,” “Wiring Inspection”), and location extensions, which are absolutely essential for local businesses. The location extensions alone accounted for an additional 12% of overall clicks to our ads, driving users directly to the Google Maps listing, which often led to direct calls.
Initial Campaign Metrics (Month 1):
- Impressions: 185,000
- Clicks: 9,120
- CTR: 4.9%
- Conversions (Leads): 280
- CPL: $53.57
- Total Spend: $15,000
- Estimated ROAS: 150% (based on client’s average lead-to-customer conversion rate and average job value)
What Didn’t Work: Broad Matches and Underperforming Geotargets
While most of our exact and phrase match keywords performed admirably, a few broad match keywords, included for discovery purposes, proved to be money pits. Terms like “electrical repair” without specific geo-modifiers attracted clicks from outside our service area or from users looking for DIY advice, not a professional electrician. These keywords had a significantly lower conversion rate (0.8% vs. 3.1% for exact match) and inflated our CPL. This is a common trap; broad match can be useful, but it requires constant vigilance and a robust negative keyword list from day one.
Furthermore, while our overall geo-targeting was effective, certain neighborhoods within our 20-mile radius, specifically those further north in Cobb County, showed a consistently higher CPL ($75+) compared to areas closer to the city center ($40-50). The volume of searches was there, but the conversion quality was lower. This was likely due to higher competition from local businesses within those specific suburban pockets.
Optimization Steps Taken: The Iterative Process
Based on the first month’s performance, we implemented several key optimizations:
- Negative Keyword Expansion: We aggressively added negative keywords. Terms like “DIY,” “how to,” “free,” and specific competitor names were added to prevent irrelevant clicks. We also added geographical negatives for areas just outside our service radius that were still triggering our ads. This single action, in my professional opinion, is the most overlooked and impactful optimization in PPC. It’s not glamorous, but it saves real money.
- Bid Adjustments by Geo-Target: We reduced bids by 20-30% for the underperforming Cobb County areas and increased bids by 10-15% for high-performing areas like Buckhead and Midtown.
- Device Bid Adjustments: We noticed that mobile users, particularly for emergency services, had a 30% higher conversion rate than desktop users. We implemented a positive bid adjustment of +25% for mobile devices across all emergency service campaigns, while slightly reducing desktop bids.
- Ad Copy Refinement: We paused ad variations with CTRs below 3% and wrote new, more compelling headlines and descriptions, emphasizing speed and reliability. We also A/B tested a new call-to-action: “Get a Free Estimate” versus “Call for Service Today” for non-emergency campaigns, finding the former performed better for scheduled work.
- Budget Reallocation: We shifted 10% of the budget from broad-match-heavy campaigns to our top-performing exact match campaigns and call-only ads. This meant pausing 38% of our initial ad groups that consistently underperformed, ensuring every dollar worked harder.
Results After Optimization (Months 2 & 3 Combined):
The optimizations had a profound effect. Our overall campaign efficiency improved dramatically.
| Metric | Month 1 | Months 2 & 3 (Avg. per month) | Improvement |
|---|---|---|---|
| Impressions | 185,000 | 160,000 | -13.5% (more targeted) |
| Clicks | 9,120 | 9,920 | +8.8% |
| CTR | 4.9% | 6.2% | +26.5% |
| Conversions (Leads) | 280 | 485 | +73.2% |
| CPL | $53.57 | $30.93 | -42.3% |
| Total Spend | $15,000 | $15,000 | 0% (same budget) |
| Estimated ROAS | 150% | 210% | +40% |
The most striking improvement was the 42.3% reduction in CPL, bringing it down to an average of $30.93. This directly translated into a significantly higher Return on Ad Spend (ROAS) of 210%. This means for every dollar Local Spark Electricians spent, they were getting $2.10 back in revenue, a healthy margin for a service business. The slight decrease in impressions was a positive sign; it meant we were reaching fewer, but far more qualified, potential customers. This is the essence of smart PPC: quality over sheer volume.
I had a client last year, a plumbing company in Gwinnett County, who insisted on running broad match keywords despite our recommendations. Their CPL was consistently over $100. It wasn’t until we convinced them to embrace a stricter negative keyword strategy and more precise targeting that we brought their CPL down to $45 and their ROAS over 200%. Sometimes, you have to show them the data to make them believers.
This campaign teardown for Local Spark Electricians demonstrates that successful PPC isn’t about setting it and forgetting it. It’s a continuous cycle of strategic planning, meticulous execution, and aggressive optimization. By focusing on intent, refining creative, and making data-driven adjustments, any business can transform its PPC efforts into a powerful engine for sustainable growth.

How often should I review my PPC campaign performance?
For most businesses, I recommend reviewing your PPC campaign performance at least weekly, especially for active campaigns. Daily checks are beneficial for high-spend or rapidly changing campaigns. This allows you to catch underperforming keywords or ads quickly and make timely adjustments to budget and bids.
What is a good Click-Through Rate (CTR) for Google Ads?
A “good” CTR varies significantly by industry and campaign type. For search campaigns, an average CTR between 3-5% is often considered decent. However, highly targeted campaigns with strong ad copy can achieve much higher CTRs, sometimes exceeding 8-10%, especially in niche markets or for high-intent keywords. For display campaigns, a CTR of 0.5-1% is typically acceptable.
Should I use broad match keywords in my Google Ads campaigns?
While broad match keywords can offer discovery and volume, I generally advise caution. They often lead to wasted spend on irrelevant searches. If you do use them, pair them with an extremely robust and continuously updated negative keyword list. Prioritize exact and phrase match for better control and higher conversion rates. My stance is: less broad, more exact.
How can I improve my Return on Ad Spend (ROAS)?
Improving ROAS involves several strategies: refining your targeting to reach more qualified leads, optimizing your ad copy to attract higher-intent clicks, continuously adding negative keywords to reduce wasted spend, adjusting bids based on performance data (e.g., device, location, time of day), and improving your landing page experience to boost conversion rates. It’s a holistic effort.
What are the most important metrics to track in PPC?
While many metrics are useful, focus on those directly tied to your business goals. Key metrics include: Cost Per Conversion (CPL/CPA), Return on Ad Spend (ROAS), Conversion Rate, Click-Through Rate (CTR), and Quality Score. These metrics give you a clear picture of efficiency, profitability, and ad relevance.
