Campaign Teardown: “Peach State Power Solutions” Lead Generation Drive

Let’s pull back the curtain on a recent campaign we managed for “Peach State Power Solutions,” a Georgia-based solar panel installation company operating across the greater Atlanta area, including Fulton, Gwinnett, and Cobb counties. Their goal? Generate high-quality leads for residential solar installations with a specific focus on homeowners interested in energy independence and tax credits.

The Challenge & Initial Strategy

Peach State Power Solutions came to us with an existing Google Ads account that was bleeding money. They were getting clicks, sure, but the leads were often unqualified, leading to a low sales close rate. Their previous agency focused heavily on broad match keywords and generic ad copy. Our mission was clear: drastically improve lead quality and reduce Cost Per Lead (CPL) while maintaining a healthy volume.

We devised a strategy centered on precision targeting, value-driven messaging, and rigorous bid management. The core idea was to identify homeowners actively researching solar solutions, not just those casually browsing. We also knew that the decision to go solar is a significant one, often involving months of research, so our campaign needed to nurture these prospects.

Campaign Metrics: Before & After

Here’s a snapshot of their performance:

Note: ROAS is estimated based on the average deal size and close rate provided by Peach State Power Solutions.

Creative Approach: Beyond the Generic

My team and I spent a considerable amount of time crafting ad copy that resonated. We moved away from “Get Solar Today!” to more nuanced messaging that addressed specific pain points and aspirations. For instance, we created ad variations like: “Cut Your Georgia Power Bill by 70% – Free Solar Quote & Tax Credit Analysis” and “Atlanta Homeowners: Own Your Energy – Learn About Federal & State Solar Incentives.”

We also implemented Responsive Search Ads (RSAs) with at least 15 distinct headlines and 4 descriptions, allowing Google’s AI to test combinations. This was critical. Our top-performing headline, “Solar Tax Credits Ending Soon? Get Your Free Estimate Now!” (a bit of urgency, and yes, it worked like a charm), consistently outperformed others in CTR by over 20%.

For display ads, we focused on high-quality visuals showcasing actual solar installations on Georgia homes, sometimes even using stock photos that closely resembled homes in neighborhoods like Buckhead or Roswell. We also integrated a short, engaging video ad for YouTube placements targeting specific affinity audiences like “Green Living Enthusiasts” and “Home Improvement DIYers.”

Targeting: The Gold Standard of Precision

This is where we made the most significant impact. Instead of broad geographical targeting across Georgia, we narrowed our focus to specific zip codes within Fulton, Cobb, and Gwinnett counties known for higher average home values and a history of environmental consciousness. We layered this with:

• Detailed Demographic Targeting: Homeowners, ages 35-65+, household income in the top 30%.
• Custom Intent Audiences: We built these by identifying users who had recently searched for terms like “best solar installers Atlanta,” “cost of solar panels GA,” “federal solar tax credit 2026,” and even competitor names. This is arguably one of the most powerful features in Google Ads right now; it lets you tap into actual purchase intent.
• Affinity Audiences: “Eco-friendly Shoppers,” “Real Estate Investors,” and “Financial News Junkies” (as these individuals are often acutely aware of long-term investments).
• Remarketing Lists: Crucially, we segmented website visitors based on pages visited. Someone who viewed the “Pricing” page but didn’t convert received different ad copy (e.g., “Still Considering Solar? Get a personalized quote in minutes!”) than someone who only visited the blog.

I remember one instance where we were seeing good CPL from our custom intent audience, but the close rate was lagging. After digging into the search query report for that audience, we found a significant number of searches for “DIY solar kits.” These individuals, while interested in solar, weren’t our target. We promptly added “DIY solar,” “solar kit,” and similar terms as negative keywords, and within two weeks, the close rate for that segment jumped by 15%. That’s the power of granular data analysis.

What Worked

1. Hyper-specific Keyword Strategy: Moving from broad match to exact and phrase match keywords, combined with an exhaustive negative keyword list, was a game-changer. We focused on long-tail keywords with clear intent.
2. Custom Intent Audiences: As mentioned, these were incredibly effective for identifying high-intent prospects. It’s like having a crystal ball for what people are actually thinking about buying.
3. Tiered Landing Page Experience: We didn’t send all traffic to a generic homepage. High-intent keywords led to a dedicated “Free Quote” landing page with a simple, prominent form, while informational searches led to pages with more detailed guides on tax credits and ROI. This dramatically improved conversion rates.
4. Aggressive A/B Testing of Ad Copy: Continuously testing headlines and descriptions, with a focus on benefits and urgency, kept our CTR high and ad relevance scores strong.
5. Smart Bidding with Conversion Value: We switched from target CPA to Target ROAS, allowing Google’s algorithm to bid more aggressively on users likely to generate higher-value leads based on historical data. This was a critical shift.

What Didn’t Work (Initially)

1. Broad Display Network Targeting: Our initial attempts at broad targeting on the Google Display Network (GDN) resulted in a lot of impressions but very few qualified leads. The CPL was atrocious. We quickly scaled back and pivoted to more targeted placements and audience layers.
2. Generic “Solar Panel” Keywords: While they brought traffic, the conversion rate was low, and the leads were often tire-kickers. The intent just wasn’t there. We paused these quickly.
3. Single Call-to-Action (CTA): Relying solely on “Get a Free Quote” limited our appeal. We found that offering “Download a Guide to Solar Tax Credits” as an alternative CTA for colder audiences significantly improved engagement and later conversions down the funnel.

Optimization Steps Taken

Optimization was an ongoing process, not a one-time event. Here’s a breakdown of our iterative improvements:

• Daily Search Query Report (SQR) Analysis: Every single day, we reviewed the SQR to identify new negative keywords and potential exact match keywords. This is non-negotiable for efficiency. We added hundreds of negative keywords, from “solar panel repair” to “DIY solar lights.”
• Bid Adjustments by Device & Time of Day: We noticed that mobile conversions had a slightly higher CPL during certain evening hours. We implemented negative bid adjustments for mobile during those times, shifting spend to desktop and more productive hours.
• Ad Schedule Optimization: We analyzed conversion data to identify peak conversion times and adjusted our ad schedule to concentrate budget during those periods, resulting in a 10% reduction in CPL during off-peak hours.
• Landing Page Enhancements: We continuously A/B tested elements on the landing pages, such as form length, headline variations, and trust signals (e.g., adding a “Georgia Certified Installer” badge). Shortening the lead form from 8 fields to 5 increased conversion rates by 8% almost overnight.
• Geographic Exclusions: We initially targeted all of Fulton County, but after analyzing lead quality from certain lower-income zip codes, we strategically excluded them. This was a tough call, but it improved our overall CPL and ROAS.
• Competitor Analysis: We regularly monitored competitor ad copy and landing pages using tools like Semrush to identify gaps and opportunities in our messaging.

One of the biggest lessons I’ve learned over the years is that perfection is the enemy of good when it comes to PPC optimization. You need to be constantly making small, data-backed adjustments. Waiting for the “perfect” setup means you’re leaving money on the table. We’re talking about real dollars here, not just theoretical gains.

The Results: A Data-Driven Success Story

By implementing these data-driven techniques, we not only achieved Peach State Power Solutions’ goal of increasing lead quality and volume but dramatically exceeded expectations. Their sales team reported a noticeable improvement in lead qualification, leading to a much higher close rate. The ROAS jumped from a meager 1.5:1 to an impressive 4.2:1 within three months, all while maintaining the same monthly ad spend. This isn’t just about clicks and impressions; it’s about generating tangible revenue for businesses.

According to a recent IAB report, digital ad spending continues to grow, emphasizing the need for businesses to make every dollar count. Our campaign for Peach State Power Solutions is a testament to the fact that with the right strategy and meticulous optimization, even within a competitive market like solar, significant gains are not just possible, but repeatable.

For any business, regardless of size, the principles remain the same: understand your audience, craft compelling messages, be ruthless with your targeting, and let the data guide every single decision. Anything less is just speculation.

The path to maximizing PPC ROI is paved with data, not assumptions. By embracing precision targeting, continuous optimization, and a deep understanding of your audience, businesses can transform their ad spend from a cost center into a powerful revenue engine.
