Get ready for a lot of 3-letter acronyms! Pay-per-click (PPC) advertising can be a powerful tool for contractors like HVAC, plumbing, and electrical businesses to connect with homeowners when they need help the most. But to make your campaigns work, you need to track the right metrics. Here are the 7 key PPC metrics every contractor should monitor to improve ROI and avoid wasting ad spend:
- Click-Through Rate (CTR): Measures how many people click your ad after seeing it. Aim for a CTR of 5% or higher.
- Cost Per Click (CPC): Tracks how much you pay for each click. Lower CPC by refining ad copy and targeting.
- Cost Per Lead (CPL): Calculates the cost of generating a lead. High CPL may signal issues with targeting or landing pages.
- Conversion Rate (CVR): Shows the percentage of clicks that turn into leads. A good baseline is 4.92%, with top campaigns exceeding 11%.
- Cost Per Acquisition (CPA): Measures the cost of turning leads into paying customers. Lower CPA by focusing on high-intent keywords.
- Return on Ad Spend (ROAS): Tracks revenue generated for every dollar spent. A 4:1 ratio ($4 earned for every $1 spent) is a strong target.
- Impression Share: Indicates how often your ad appears compared to competitors. Aim for a top impression rate of 60%-80%.
Tracking these metrics helps contractors make smarter decisions, optimize campaigns, and turn ad spend into profitable jobs.
How PPC KPIs Are Used To Track and Measure Success
1. Click-Through Rate (CTR)
CTR is calculated using the formula: (Clicks ÷ Impressions) × 100. For example, if your ad gets 1,000 impressions and 60 clicks, your CTR would be 6%.
For home improvement contractors, Search Engine Journal says the average CTR hovers around 6.37%. If your CTR falls below 3%, it’s a red flag that your ad copy or targeting might need adjustments.
Impact on ROI
CTR isn’t just a number, it’s actually a key player in how well your ads perform. Google factors CTR heavily when assigning your Quality Score. A higher CTR signals that your ad is relevant, which can lead to better placements and lower costs per click. This means you can generate more leads without stretching your budget.
If you had a high conversion rate but a low click-through rate, you'd want to improve your click-through rate so you have a chance of improving your conversions later in the process.
A strong CTR increases clicks and ensures your ad dollars are spent reaching homeowners who are actively looking for your services. Once you’ve nailed your CTR, take a closer look at your Cost Per Click (CPC) to refine your ad strategy even further.
2. Cost Per Click (CPC)
Cost Per Click (CPC) is the average cost of each click on your ad. It’s calculated using this formula: Total Cost of Clicks ÷ Total Number of Clicks. For instance, if you spend $200 on ads and get 50 clicks, your CPC would be $4.00.
For contractors, knowing your CPC is essential because it determines how efficiently your ad budget is being used. Since CPC rates differ across industries, it’s important to focus on benchmarks specific to your market.
Impact on ROI
Keywords related to emergencies, like "24-hour AC repair", usually have higher CPCs. Why? They target people who are ready to take action immediately, such as booking a service. The challenge lies in balancing these costs with the likelihood of conversion, ensuring each click adds value to your return on investment (ROI).
Paying attention to CPC trends can help you fine-tune your strategy before diving into more advanced optimizations.
To reduce CPC and get better results, focus on improving your ad copy, landing pages, and click-through rate (CTR). Another tactic is targeting long-tail keywords. For example, instead of bidding on a broad term like "HVAC", use more specific phrases like "furnace installation in Dallas." These keywords often attract more qualified traffic at a lower cost.
Also, regularly check your search term reports. Add negative keywords like "salary", "DIY", or "parts" to prevent wasting money on irrelevant clicks. If certain keywords are driving up costs without generating leads, pause them and shift your budget to terms that perform better.
3. Cost Per Lead (CPL)
Understanding Cost Per Lead (CPL) is just as important as mastering CTR and CPC when it comes to turning ad spend into profitable leads. CPL measures how much you're spending to generate each lead whether that's a form submission, phone call, or quote request. The formula is straightforward: Total Ad Spend ÷ Total Number of Leads. For example, if you spend $500 on ads and generate 25 leads, your CPL is $20.00.
For contractors, CPL plays a bigger role than it does for e-commerce businesses. You're not selling products directly online; instead, you're generating leads that need to be nurtured through your sales pipeline. Every lead requires follow-up before it can turn into a paying customer.
Impact on ROI
CPL is a direct indicator of how efficiently your marketing dollars are working to bring in potential customers. If your CPL is high, it could point to problems like poor audience targeting, weak ad creative, or a landing page that isn’t converting visitors.
This metric connects your marketing budget to potential revenue. If your CPL exceeds the value of a lead, you're losing money. For instance, if the average plumbing job brings in $800 and your close rate is 20%, each lead is worth about $160. A CPL higher than $160 means you're operating at a loss for every lead generated.
4. Conversion Rate
Metrics like CTR and CPL are great for gauging initial engagement and cost efficiency, but conversion rate tells you how well that engagement turns into actionable leads. This metric calculates the percentage of clicks that lead to conversions, such as form submissions, phone calls, or quote requests. The formula is straightforward: Total Conversions ÷ Total Clicks × 100. For instance, if 100 people click on your ad and 8 of them take action (like filling out a form) your conversion rate would be 8%. This number reveals whether your ads and landing pages are successfully turning interest into leads.
Impact on ROI
Conversion rate plays a big role in ROI because it directly affects your Cost Per Acquisition (CPA). A higher conversion rate means you’re spending less to acquire each new customer. On the flip side, if clicks aren’t converting into leads, your ad spend is essentially wasted. As some owners say,
"If you don't have a healthy conversion rate, you're just lighting money on fire."
According to that same SEJ article mentioned in metric 1, as of May 2025, the median conversion rate for Google Ads across industries was 6.6%. Advertisers in the top 5 averaged an impressive 9.67%. For contractors, hitting these benchmarks means your ads and landing pages are fully aligned with what potential customers are searching for. This metric is key to your entire PPC strategy.
Relevance to PPC Campaign Goals
For contractors, the ultimate goal of a PPC campaign is usually generating leads, whether that’s through phone calls or estimate requests. Conversion rate is the key indicator of whether your targeting, ad copy, and landing page are working together. If you notice a high click-through rate but a low conversion rate, it’s a red flag. It means people are interested enough to click but something on your landing page is stopping them from taking the next step. To fix this, make sure your landing page delivers exactly what your ad promises.
5. Cost Per Acquisition (CPA)
Cost Per Acquisition (CPA), sometimes called cost per conversion, measures how much you’re spending to turn clicks into actual jobs or customers. The formula is straightforward: divide your total ad spend by the number of conversions. For instance, if you spent $500 and gained 10 calls or quote requests, your CPA would be $50. For contractors, this metric directly links advertising costs to successful job acquisitions, making it easier to see exactly how much you’re paying for each potential job.
Impact on ROI
CPA plays a critical role in ROI-focused advertising strategies because it shows the actual value of your ad spend in generating tangible business results, not just traffic. A lower CPA means you’re spending less to acquire each lead, which ultimately boosts your profitability. On the other hand, a high CPA often signals areas for improvement, such as refining your targeting, improving ad copy, or rethinking keyword choices to avoid wasting budget on less relevant search terms.
Beyond just tracking lead quality, CPA highlights how efficiently your campaign turns potential leads into booked jobs. While Cost Per Lead (CPL) tells you the price of getting an inquiry, CPA digs deeper, focusing on the cost of converting that inquiry into an actual job. This difference is important because not every lead will convert. For example, many contractors assume they close 1 in 3 leads, but in reality, the rate is often closer to 1 in 5 or 6 (around 16–20%).
6. Return on Ad Spend (ROAS)
Return on Ad Spend (ROAS) measures how much gross revenue you generate for every dollar spent on advertising. It’s calculated by dividing total revenue by ad spend. For instance, if you invest $2,000 in ads and bring in $10,000 in revenue, your ROAS is 5.0 (or 500%), meaning you earned $5 for every $1 spent. This metric offers a clear snapshot of a PPC campaign's financial effectiveness.
Impact on ROI
ROAS helps determine whether your advertising dollars are translating into profit or just covering costs. A ROAS of 1:1 means you're breaking even, earning exactly what you spend. For contractors and other service-based businesses, a 2:1 ROAS often signals profitability, while a 4:1 ratio reflects strong performance. However, keep in mind that ROAS focuses solely on ad spend, unlike ROI, which accounts for all business expenses.
This distinction allows for a more nuanced understanding of your campaign’s financial health.
Relevance to PPC Campaign Goals
While ROAS is a valuable metric, it’s not the only measure of success. Because it treats all revenue equally, it can obscure profitability. If high revenue comes from low-margin jobs, you might not be making as much money as you originally thought. Many contractors are now adopting Profit on Ad Spend (POAS), which incorporates profit margins for a clearer picture.
To ensure accurate ROAS tracking, integrating your CRM’s sales data with PPC platforms is key. This connection strengthens revenue attribution and supports smarter decision-making.
7. Impression Share
Impression share represents the percentage of times your ad appears out of the total opportunities it had to show up. For instance, if your impression share is 40%, it means your ad was displayed in 4 out of every 10 chances, leaving 60% of potential impressions unrealized.
Why It Matters for PPC Campaigns
For contractors, impression share is a key metric to understand how often your ad is visible to potential customers during high-intent searches. It provides insight into your competitive standing by showing how frequently your ad appears compared to others bidding in the same space. A low impression share often signals that competitors are outperforming you in auctions. Depending on the ad platform, your competitors could be ahead of you due to higher bids, better ad quality, a single viral ad, or larger budgets. Experts suggest aiming for a top impression rate of 60% to 80%, while the absolute top impression rate (the very first ad position) should ideally fall between 20% and 30%. Tracking this metric helps you identify gaps and refine your campaign to maximize visibility.
How to Measure It
Google Ads breaks down impression losses into two categories: Lost to Budget (when your daily budget runs out) and Lost to Rank (when your ad rank isn’t high enough). The Auction Insights report is particularly useful for understanding how your ads stack up against local competitors.
If you're losing impression share due to budget constraints, consider increasing your daily spend to ensure your ad shows up consistently. If the loss is tied to rank, focus on improving your Quality Score by refining landing pages and targeting high-performing, specific keywords.
Actionable Insights for Contractors
I've mentioned a few of these in the 7 PPC metrics above, but to make this easier on you, I'll list actions you can take to improve your numbers across the board.
- Review highest-cost first: To lower your ad costs and improve results, start by reviewing your account for high-cost keywords and audience segments. Adjust your strategy to focus on more cost-effective options.
- Optimize for the right action: Focus on optimizing for phone calls, as they often indicate urgent, high-intent interest. Adding features like call extensions and click-to-call buttons can help improve lead quality while reducing CPL. In the home improvement industry, where the average click-through rate is around 6%, making it easier for potential customers to contact you can have a noticeable impact.
- Use negative keywords: Regularly review your search queries and add negative keywords like "DIY", "jobs", "salary", or "how-to" to filter out users who are unlikely to hire a professional
- Check consistency in experience: Ensure your landing page aligns with your ad copy. For instance, if someone clicks on an ad for "emergency pipe repair" and lands on a generic "about us" page, your CPL will likely increase due to lower conversion rate.
- Track your sources: Every lead source should be known with precision. Having accurate data allows you to make informed decisions instead of relying on estimates. If one service consistently meets your CPL goals while another underperforms, shift your budget toward the high-performing service until you optimize the underperforming one.
- Improve landing pages: Simple, clear calls to action and easy conversion paths can increase ROAS without adding to your ad spend.
- Break it down by category: Analyze ROAS by service type, location, and device. For example, a roofing campaign might outperform a plumbing one, or mobile ads might yield better results in certain areas.
- Separate branded and non-branded searches: Reporting these separately helps clarify which campaigns are driving real value. Branded means it focused on searches for your company name, whereas non-branded means it was for a service or keyword
- Use Target ROAS (tROAS): Google Ads' automated bidding can align with your revenue goals, optimizing performance with AI
- Assign lead values: Calculate lead worth based on your average job ticket and closing rate to measure profitability more accurately, avoiding vanity metrics.
- Get Google Guaranteed: You might also explore Google Local Services Ads (LSAs) with the "Google Guaranteed" badge. These ads operate on a pay-per-lead model, helping you control costs while expanding your reach.
- High-intent focused: Zero in on high-intent keywords like "bathroom remodel Phoenix" instead of broad terms like "construction."
- Peak hour shifts: Know when homeowners are more likely to search for services. This ensures your ads remain visible during critical periods of high demand. Maintaining a strong impression share is crucial for staying top-of-mind during service emergencies, helping you capture more local customers when they need you most.
All of these actions help you shift your budget away from underperforming areas and invest more in those that deliver better results.
Why Tracking These Metrics Matters for Contractors
Failing to track key metrics is like throwing your ad budget into a black hole or lighting money on fire. Data-driven decisions can replace guesswork with measurable growth. The numbers speak for themselves: companies that invest in paid advertising often see impressive returns, with top performers achieving multiples on their investment. By analyzing the right data, contractors can make smarter decisions about where to allocate their budgets.
These metrics highlight which keywords and campaigns drive actual conversions and which ones waste your money on clicks that never lead to jobs. For contractors, every dollar spent on irrelevant clicks is a dollar that could have been better used for emergency repair calls or scheduled appointments. Keeping a close eye on metrics like Cost Per Lead (CPL) and Return on Ad Spend (ROAS) allows you to shift your budget from underperforming campaigns to those that generate real results.
Tracking also helps you attract better-quality leads. For field service businesses, phone calls often indicate higher buyer intent compared to form submissions, especially for urgent services. If you notice high click volumes but low conversions, it’s a red flag. Something may be off with your targeting or landing page performance. Monitoring these metrics ensures your strategy stays on track, reinforcing the importance of a data-driven approach for field service businesses.
Profitability comes from making precise decisions based on reliable data. This is true across all field service KPIs, but especially PPC metrics.
For example, a strong ROAS of 4:1, earning $4 for every $1 spent, is considered a very solid benchmark. But without consistent tracking, you won’t know if you’re hitting that target. Avoid getting distracted by vanity metrics like impressions or likes. Vanity metrics are those stats that you like to show off, but in the end, really don't mean anything.
With the right tools and a focus on the right metrics, you can take full control of your PPC campaigns and drive meaningful results.
