Most Google Ads reports bury the six numbers that actually tell you whether your campaigns are working under a pile of impressions, clicks, and CTR charts that look impressive but don't pay the bills. The numbers that matter for a home service business are: cost per lead, conversion rate, average CPC, impression share lost to budget, impression share lost to rank, and the search terms report. Check those six every week and you'll know within minutes whether your account needs a conversation with your ad manager or is doing exactly what it should.
Everything else in the dashboard — impressions, CTR, quality score — is diagnostic. It helps explain why the six numbers above look the way they do. It's not the scoreboard.
What is cost per lead and why is it the most important number?
Cost per lead (labeled \"Cost / Conv.\" in Google Ads) is what you paid, on average, for each form fill or phone call the platform counted as a conversion. It's the closest thing to a bottom-line number in the report because it ties spend directly to leads, not clicks. Home-service Google Ads CPLs typically run $40–$120 for routine services and can run considerably higher — often $150–$300+ — for big-ticket categories like roofing, remodeling, or kitchen renovations, where fewer people convert but each job is worth thousands.
The trap: CPL by itself doesn't tell you if the leads were any good. A $45 CPL that produces tire-kickers is worse than a $95 CPL that produces signed contracts. Always look at CPL next to close rate before deciding a number is \"bad.\"
What conversion rate should a contractor expect from Google Ads?
Conversion rate is the percentage of clicks that turn into a lead (call, form, or booked appointment). For home service search campaigns, a healthy range is typically 5–10% site-wide, with well-optimized landing pages for high-intent, branded, or emergency terms pushing 10–15% or higher. Anything consistently under 3% usually points to a landing page problem — slow load time, no clear phone number, weak offer — rather than a targeting problem.
Conversion rate is also where campaign structure shows up fastest. If a campaign is sending broad \"HVAC company near me\" traffic to a generic homepage instead of a service-specific landing page, conversion rate will lag even if the keywords are exactly right.
What's a normal average CPC for home service keywords?
Average cost-per-click varies enormously by trade and by how competitive the local market is. Emergency and high-value categories — plumbing, roofing, kitchen and bath remodeling — regularly see CPCs in the $15–$45+ range, with kitchen renovation and remodeling keywords in dense metros pushing past $45. Lower-ticket, less-competitive services like painting or landscaping often run $5–$20 per click. There's no universal \"good\" CPC — the only useful comparison is your CPC against your CPL and close rate. A $30 CPC is fine if it's converting into $8,000 jobs at a reasonable rate.
What does impression share lost to budget mean, and why should contractors care?
Impression share tells you what percentage of eligible auctions your ads actually showed up in. \"Lost to budget\" means your daily budget ran out before the day's searches did — you're leaving demand on the table that your own campaign already proved it could convert. \"Lost to rank\" means your bid or quality score wasn't competitive enough to show, even with budget left.
These two numbers point to opposite fixes. Lost-to-budget over 20-25% on a campaign that's already converting well is usually a signal to raise the daily budget — you're capping proven demand. Lost-to-rank above 20-25% usually means the bid strategy, ad relevance, or landing page experience needs work before spending more makes sense. Confusing the two is the single most common reason contractors either overspend chasing the wrong fix or underspend on a campaign that was ready to scale.
Why does the search terms report matter more than most people think?
The search terms report shows the actual phrases people typed before your ad showed and they clicked. It's the fastest way to catch wasted spend — clicks from searches like \"HVAC certification classes\" or \"DIY garage door spring replacement\" that will never convert into a paying job but still cost money every time someone clicks. Reviewing this report weekly and adding negative keywords is one of the cheapest ways to lower blended CPL without touching bids at all.
A search terms report that hasn't been reviewed in a month or more is usually leaking 10-20% of spend on irrelevant clicks, particularly on Performance Max and broad-match campaigns where Google has more room to guess.
The 6 numbers, at a glance
| Metric | Where to find it | Typical healthy range | Red flag |
|---|---|---|---|
| Cost per lead | Campaigns > Cost / Conv. | $40–$120 (routine services); $150–$300+ (big-ticket) | Rising 30%+ month over month with no volume gain |
| Conversion rate | Campaigns > Conv. Rate | 5–10% (site-wide); 10–15%+ (high-intent pages) | Below 3% consistently |
| Average CPC | Campaigns > Avg. CPC | $5–$45+ depending on trade and market | CPC rising without CPL or close rate improving |
| Impression share lost (budget) | Campaigns > Auction Insights / Impr. share columns | Under 20-25% on converting campaigns | Over 25% on a campaign with a healthy CPL |
| Impression share lost (rank) | Campaigns > Impr. share columns | Under 20-25% | Over 25% even after raising bids |
| Search terms report | Insights & Reports > Search Terms | Reviewed weekly, negatives added monthly | Untouched for 30+ days |
How often should a contractor actually check these numbers?
Weekly is enough for CPL, conversion rate, and the search terms report — these move fast and catch problems early, like a landing page that broke or a new competitor pushing CPCs up. Impression share numbers are worth a monthly look, since budget and rank issues tend to develop over weeks, not days. Pulling every number daily usually just creates noise; the goal is catching real trends, not reacting to normal day-to-day swings.
It's also worth checking these six numbers against the phone: if CPL looks great but the office says lead quality has dropped, that's usually a sign to look at call recordings and CallRail data alongside the Google Ads report, not just the platform's own conversion counts.
Frequently asked questions
Should I judge my campaign on CPL alone?
No. CPL tells you what a lead cost, not whether it turned into a job. Pair CPL with close rate and average job value whenever possible — a higher CPL that converts into signed contracts is doing more for the business than a lower CPL full of tire-kickers.
What's a good click-through rate for home service ads?
CTR is a useful diagnostic but not one of the six core numbers, because a high CTR with a low conversion rate usually means the ad copy is over-promising relative to the landing page. As a rough guide, 4–8% CTR on search campaigns is typical for well-matched keywords and ad copy; much lower usually points to weak ad relevance or the wrong match type.
How do I know if my ad manager is optimizing the account or just monitoring it?
Ask to see the search terms report and the negative keyword list added in the last 30 days, along with a recent adjustment to impression-share-losing campaigns. If those don't exist, the account is likely being watched, not actively managed.
My CPL looks fine but leads have dropped off in quality — what should I check first?
Start with the search terms report to see if broad or Performance Max targeting has drifted toward irrelevant searches, then check call recordings against ad source to confirm the leads Google is counting as conversions are the ones your office actually wants. Nova Marketing (novamarketing.ai) builds this cross-check into weekly reporting for exactly this reason — a real-time dashboard paired with weekly email updates and monthly strategy calls, so CPL numbers never get reviewed in isolation from lead quality. If you want a second set of eyes on your account's six numbers, a free strategy call is a good place to start.
