What Is a Good ROAS for a Service Business?
Most agency reports lead with impressions and clicks. But if you’re a service business owner spending $3,000 to $10,000 a month on Google Ads, there’s only one number that matters: are you making money on that spend?
That’s what ROAS tells you. And most owners either don’t know their number or are using the wrong benchmark to evaluate it.
This post breaks down exactly what a good ROAS looks like for a service business — with the vertical-specific math to back it up.
What ROAS Actually Means for a Service Business
ROAS stands for Return on Ad Spend. The formula is simple: revenue generated divided by dollars spent on ads. A 4:1 ROAS means you earned $4 in revenue for every $1 spent on ads.
WordStream Google Ads Benchmarks puts the average ROAS across all industries at approximately 2:1 — meaning most businesses are earning $2 for every dollar spent. That’s breakeven territory for most service businesses, not a win.
A 4:1 ROAS is the threshold most performance-focused agencies use as a profitability benchmark. But here’s the thing: that number means something very different for an HVAC company with a $3,200 average job than it does for a chiropractor billing $85 per visit.
ROAS is a ratio. To use it correctly, you have to anchor it to your actual revenue per customer — not an industry average pulled from a blog post.
Why the Industry Average ROAS Benchmark Is Misleading
Here’s where most service business owners get burned: they see a benchmark, compare their own number, and make a bad decision — either killing campaigns that are actually working or keeping ones that are quietly draining cash.
The LocaliQ Home Services Advertising Benchmarks report shows the average cost per lead for home services advertisers at $66.02. That CPL can support a great ROAS for a plumber closing $800 emergency jobs. For a gym charging $49/month memberships, the same CPL is a problem unless you’re accounting for lifetime value.
The same data shows home services conversion rates averaging 7.98% — one of the higher rates across all industries. That’s a structural advantage service businesses have. The question is whether your campaigns are built to capture it.
For a deeper look at how campaign structure affects these numbers, the Google Ads for Local Service Businesses complete guide walks through bidding, targeting, and what local service campaigns should actually look like.
The Owner Math: What ROAS Should You Actually Target?
Stop benchmarking against averages. Build your ROAS target from your own numbers. Here’s the framework:
Step 1: Know your average job value (AJV). Not your highest job. Your average closed revenue per new customer.
Step 2: Know your close rate. What percentage of leads from Google Ads actually become paying customers? Most local service businesses run 40–70% depending on the vertical.
Step 3: Back into your maximum CPL. If your AJV is $1,500 and you close 50% of leads, every lead is worth $750 in expected revenue. If you want a 4:1 ROAS, your CPL ceiling is $187.50.
That math is the only benchmark that matters for your business. Our Owner Math framework for CAC, ROAS, and payback period walks through this calculation in full — including how to factor in lifetime value and seasonality.
| Vertical | Avg Job Value | Target CPL | Good ROAS Benchmark | Simply Digital Benchmark |
|---|---|---|---|---|
| HVAC | $1,800–$4,500 | $60–$120 | 6:1–12:1 | $47 CPL achieved |
| Plumbing | $400–$1,200 | $50–$100 | 5:1–10:1 | Industry avg: $66 CPL |
| Chiropractic | $800–$2,400 LTV | $40–$80 | 4:1–8:1 | $38/patient achieved |
| Gym / Fitness | $600–$1,800 LTV | $35–$75 | 4:1–6:1 | 4.2x ROAS achieved |
| Dental | $1,200–$5,000 LTV | $80–$150 | 5:1–10:1 | LTV-adjusted target |
Notice how the ROAS targets vary dramatically by vertical. A dental practice billing $4,000 for an implant can afford a higher CPL — and should be targeting a higher absolute ROAS — than a gym selling $49/month memberships. Same benchmark, completely different math.
Where Most Service Businesses Are Leaving ROAS on the Table
If your ROAS is below 3:1, the problem is almost never your ad budget. It’s one of three things: wrong keywords, broken tracking, or a landing page that isn’t converting.
Wrong keywords means you’re paying for traffic that can’t buy. Broad match campaigns on generic terms like “HVAC” or “chiropractor” send you tire-kickers and out-of-area clicks. Your CPL climbs. Your ROAS tanks.
Broken tracking means you don’t actually know your ROAS — you’re guessing. If your Google Ads account isn’t tracking phone calls, form fills, and booked appointments as conversions, every optimization decision is based on incomplete data. Google Ads Smart Bidding requires at least 15–30 conversions in the past 30 days to optimize effectively — which means tracking gaps don’t just hurt your reporting, they actively block Google’s algorithm from improving your results.
Landing page failure is the most common issue we find in new client audits. Sending paid traffic to a homepage is the single fastest way to destroy ROAS. High-intent clicks need high-intent pages — specific to the service, the city, and the problem the customer typed into Google.
How to Improve Your ROAS Without Increasing Budget
More budget doesn’t fix a broken campaign. Better structure does. Here’s where to start:
Tighten your match types. Move your highest-converting keywords to exact match and phrase match. Stop paying for searches that don’t match your actual services.
Build service-specific landing pages. One page per core service, optimized for one city. The conversion rate jump from a generic homepage to a dedicated landing page routinely moves CPL from $90 to $45 — without touching the budget.
Audit your negative keyword list. Most new accounts we audit have hundreds of irrelevant searches burning budget. DIY terms, competitor names, informational queries — these should be excluded before you run a single day of ads.
Use call tracking tied to revenue. Know which campaigns are generating booked jobs — not just calls. If you’re tracking calls but not connecting them to actual closed revenue, you’re still flying blind on ROAS.

The ROAS Number That Should Concern You Most
It’s not a low ROAS. It’s an unknown ROAS.
Plenty of service businesses are running Google Ads with no idea whether the spend is profitable. The agency sends a report full of clicks and impressions. The owner assumes it’s working because the phone is ringing. But without connecting ad spend to closed revenue, there’s no ROAS — there’s just spend.
The fix is attribution. Every lead source needs to be tracked. Every closed job needs to be tied back to the campaign that generated the lead. When you have that data, ROAS becomes a real number you can optimize against — not a metric you report to feel good about.
HubSpot’s marketing statistics note that paid search can increase brand awareness by up to 80% — a real but hard-to-measure compounding effect. That’s worth knowing. But it’s not a substitute for tracking direct revenue. For a service business spending $5,000/month on ads, the only question that matters is: what closed revenue did that $5,000 generate?
A good ROAS for a service business isn’t a single number. It’s the ratio that proves your ad spend is profitable given your job value, close rate, and cost structure. For most local service businesses, that means 4:1 minimum — and 6:1 or better when the vertical supports it.
If you don’t know your current ROAS, or your agency can’t tell you what it is, that’s the first problem to solve.
