When Should You Start Paying for Ads?
Before spending a dollar on advertising, make sure your foundation is solid. That means:
- Your Google Business Profile is claimed and optimized
- Your website loads fast, looks professional, and works on mobile
- You have a clear call-to-action and way to capture leads
- You can actually handle more work right now
If you are already booked out three months, ads will just create frustrated leads you cannot serve. Fix your capacity first.
If you are ready for more leads and have at least $500/month to invest, paid advertising is the fastest way to fill your pipeline.
Google Ads vs. Facebook Ads: Which One?
This is not an either/or decision, but if you have to pick one, here is the framework:
Google Ads (Search)
Best for: Emergency and urgent services, high-intent searches
When someone types "emergency plumber near me" or "roof leak repair," they need help now. Google Search Ads put you at the very top of results for these queries. This is the highest-intent traffic you can buy.
Typical cost per click: $5-$50+ depending on your industry and location. Competitive trades like HVAC, plumbing, and roofing are on the higher end.
Who should use it: Any service business where customers search Google when they have a problem. This covers most contractors.
Facebook and Instagram Ads
Best for: Planned projects, brand awareness, retargeting
Nobody wakes up and scrolls Facebook looking for a plumber. But if someone has been thinking about a kitchen remodel, a beautiful before-and-after photo in their feed might push them to take action.
Facebook Ads are interruption-based. You are inserting yourself into someone's feed. This works for:
- Showcasing completed projects with visual impact
- Promoting seasonal offers ("Book your spring AC tune-up")
- Retargeting website visitors who did not convert
- Building brand awareness in your service area
Typical cost per click: $1-$5, much cheaper than Google. But the intent is lower, so conversion rates are also lower.
Google Local Services Ads (LSAs)
Best for: Service businesses that want pay-per-lead instead of pay-per-click
LSAs appear above regular Google Ads with a "Google Guaranteed" badge. You pay per lead (phone call or message), not per click. Costs vary by industry and market but typically run $15-$50 per lead.
The qualification process includes background checks and license verification, which also builds trust with customers.
Setting Up Your First Google Ads Campaign
Campaign Structure
Keep it simple to start:
- One campaign focused on your highest-margin service
- 2-3 ad groups organized by service type
- 10-20 keywords per ad group -- tightly themed
Keyword Selection
Focus on keywords with buying intent:
- "[Service] near me" (e.g., "plumber near me")
- "[Service] in [City]" (e.g., "roof repair in Dallas")
- "Emergency [service]" (e.g., "emergency electrician")
- "[Service] cost" or "[service] estimate"
Avoid broad keywords like "plumbing" -- you will waste money on people searching for DIY tutorials or plumbing supply stores.
Negative Keywords
Equally important as your target keywords. Add negatives for:
- "DIY," "how to," "tutorial"
- "jobs," "hiring," "salary" (job seekers, not customers)
- "free" (unless you offer free estimates)
- Competitor brand names (usually)
Writing Ads That Convert
Your ad needs three things:
- Relevance: Match the search intent. If someone searches "AC repair," your ad headline should say "AC Repair" -- not "Full HVAC Services."
- Differentiation: Why you over the next result? "Same-Day Service," "Licensed & Insured," "4.9 Stars on Google."
- Call-to-action: "Call Now for a Free Estimate," "Book Online Today."
Landing Pages
Never send ad traffic to your homepage. Create dedicated landing pages for each service you advertise. Each landing page should have:
- A headline that matches the ad and search query
- Your phone number prominently displayed
- A simple contact form
- Social proof (reviews, ratings, certifications)
- No navigation menu (keep them focused on converting)
Budget Management
Starting Budget
Start with $500-$1,000/month on Google Ads for a single service campaign. This gives you enough data to learn what is working within 30-60 days.
Bidding Strategy
Start with "Maximize Clicks" to gather data. After you have 30+ conversions, switch to "Maximize Conversions" or "Target CPA" to let Google optimize automatically.
Daily Budget Distribution
Set your daily budget and let Google distribute it. If your monthly budget is $900, set your daily budget to $30. Google may spend up to 2x your daily budget on high-traffic days but will not exceed your monthly limit.
Tracking and Optimization
Call Tracking
Set up call tracking so you know which ads generate phone calls. Google Ads offers a free call forwarding number, or use a third-party service for more detail.
Conversion Tracking
At minimum, track:
- Phone calls from ads (set up in Google Ads)
- Form submissions on your website
- Cost per lead (total spend divided by total leads)
- Lead-to-job conversion rate
Monthly Optimization Checklist
- Review search terms report and add negative keywords
- Pause underperforming keywords (high spend, no conversions)
- Test new ad copy against existing ads
- Check your Quality Score and improve where possible
- Adjust bids based on day-of-week and time-of-day performance
- Review geographic performance and exclude low-performing areas
Common Paid Advertising Mistakes
- No conversion tracking: Flying blind. You must know what each lead costs.
- Sending traffic to your homepage: Use dedicated landing pages.
- Too many keywords: Start narrow, expand as you learn.
- Ignoring your ads after setup: This requires weekly attention, especially in the first 90 days.
- Giving up too soon: The first 30 days are a learning period. Do not judge ROI until month two or three.
- Not following FTC guidelines: All advertising must be truthful. Claims must be substantiated. Disclose any material terms of offers.
When to Hire a Professional
If you are spending over $2,000/month on ads, consider hiring a PPC specialist or agency. A good one should:
- Charge a flat management fee, not a percentage of ad spend
- Provide monthly reports with clear metrics
- Give you full access to your ad accounts (you own them, not the agency)
- Show improvement in cost per lead over time
Your time is valuable. If managing ads takes hours away from running your business, the math usually favors hiring help.
Google Ads Benchmarks by Industry
Understanding typical performance metrics helps you evaluate whether your campaigns are working. Here are realistic benchmarks for service businesses:
| Industry | Avg. Cost Per Click | Avg. Cost Per Lead | Avg. Conversion Rate | Avg. Click-Through Rate |
|---|---|---|---|---|
| Plumbing | $8-$25 | $30-$75 | 5-10% | 3-6% |
| HVAC | $10-$35 | $40-$100 | 4-8% | 3-5% |
| Electrical | $8-$20 | $30-$70 | 5-10% | 3-6% |
| Roofing | $15-$50 | $50-$150 | 3-7% | 2-5% |
| Remodeling | $10-$40 | $75-$200 | 3-6% | 2-4% |
| Landscaping | $5-$15 | $15-$50 | 5-12% | 4-7% |
| Cleaning | $3-$12 | $10-$40 | 6-15% | 5-8% |
| Legal Services | $20-$100 | $75-$300 | 3-7% | 2-4% |
| Accounting | $10-$30 | $40-$120 | 4-8% | 3-5% |
If your numbers are significantly worse than these ranges, something is off -- usually keyword targeting, ad copy, or landing page quality. If your numbers are better, you have room to increase spend and capture more leads.
Google Local Services Ads: A Deep Dive
Local Services Ads (LSAs) are increasingly the best advertising option for service businesses. Here is why and how to use them:
How LSAs Work
- You appear at the very top of Google search results, above regular Google Ads
- You pay per lead (phone call or message), not per click
- You earn a "Google Guaranteed" or "Google Screened" badge after passing background checks
- Customers can book directly from the ad
- You set a weekly budget, not a per-click bid
LSA Cost by Industry
| Industry | Typical Cost Per Lead | Lead Quality |
|---|---|---|
| Plumbing | $15-$30 | High (urgent, ready to hire) |
| HVAC | $20-$40 | High |
| Electrical | $15-$30 | High |
| Roofing | $25-$50 | Moderate to High |
| Locksmith | $10-$20 | Very High (emergency) |
| Garage Door | $15-$30 | High |
| Cleaning | $10-$25 | Moderate |
Maximizing Your LSA Performance
- Complete your profile thoroughly. Fill in every service type. Google matches you to searches based on the services you list.
- Respond to every lead fast. LSA algorithms prioritize businesses that respond quickly and consistently.
- Collect reviews through LSAs. Google reviews that mention specific services boost your LSA ranking.
- Dispute bad leads. You can dispute charges for spam calls, wrong service requests, and leads outside your service area. Do this within 30 days of the lead.
- Set your budget based on capacity. If you can handle 20 leads per week, set your budget to generate roughly that volume. Do not overcommit.
Building Landing Pages That Convert Ad Traffic
The single biggest mistake in paid advertising is sending traffic to your homepage. Your homepage tries to serve everyone. A landing page serves one specific purpose: converting the visitor into a lead.
Landing Page Must-Haves
- Headline matching the ad: If your ad says "Emergency Plumber in Dallas," the landing page headline should say "Emergency Plumber in Dallas" -- not "Welcome to Smith Plumbing."
- Phone number above the fold: Large, clickable on mobile, and prominent. Over 60% of search traffic is mobile.
- Simple contact form: Name, phone number, brief description of the problem. That is it. Every additional field you add reduces conversions.
- Social proof: 2-3 Google review quotes, your star rating, number of reviews, certifications, and years in business.
- Zero navigation: Remove the header menu. The visitor should have only two options: call you or fill out the form. No distractions.
- Clear call-to-action: "Call Now for a Free Estimate" or "Get Your Free Quote in 60 Seconds."
Landing Page Benchmarks
| Metric | Poor | Average | Good | Excellent |
|---|---|---|---|---|
| Conversion Rate | Under 3% | 3-5% | 5-10% | Over 10% |
| Bounce Rate | Over 70% | 50-70% | 30-50% | Under 30% |
| Time on Page | Under 30 sec | 30-60 sec | 1-2 min | Over 2 min |
| Mobile Load Time | Over 5 sec | 3-5 sec | 2-3 sec | Under 2 sec |
A well-built landing page can double or triple your conversion rate compared to sending traffic to your homepage. That means the same ad spend generates two to three times as many leads.
Retargeting: Bringing Back Visitors Who Did Not Convert
Most website visitors leave without contacting you. Retargeting shows them your ads as they browse other websites and social media, keeping your business top of mind.
How Retargeting Works
- A visitor comes to your website from a Google search or ad
- A small tracking pixel (code snippet) marks them as a visitor
- Over the next 30-90 days, your ads follow them across the web -- on Facebook, Instagram, news sites, and other websites
- When they are ready to make a decision, your business is the one they remember
Retargeting Budgets
Retargeting is the cheapest form of paid advertising because you are targeting a small, warm audience:
- Facebook/Instagram retargeting: $5-$15/day ($150-$450/month)
- Google Display retargeting: $5-$10/day ($150-$300/month)
- Combined approach: $300-$750/month
At these budgets, retargeting typically produces a cost per lead 50-70% lower than cold advertising because the audience already knows who you are.
Best Practices for Retargeting
- Show different ads than what they already saw. If they visited your "kitchen remodeling" page, show them a kitchen remodeling testimonial or before-and-after.
- Set frequency caps so the same person does not see your ad 50 times a day. Three to five impressions per week is the sweet spot.
- Exclude people who already converted. If they filled out your form, stop showing them ads.
- Use time-based messaging: "Still thinking about that bathroom remodel? We have openings in April."
Calculating Your Maximum Cost Per Lead
Before you spend a dollar on ads, calculate the maximum you should pay per lead. Work backward from your financials:
Step 1: Determine your average job value. Example: $3,000.
Step 2: Determine your close rate from leads. Example: 35%.
Step 3: Determine your target marketing cost as a percentage of revenue. Example: 10%.
Step 4: Calculate maximum cost per lead.
Maximum CPL = Average Job Value x Close Rate x Target Marketing Percentage Maximum CPL = $3,000 x 0.35 x 0.10 = $105
In this example, you can afford to pay up to $105 per lead and still hit your marketing ROI target. If your Google Ads are generating leads at $60 each, you are well within range. If they are generating leads at $150 each, either optimize the campaign or reconsider the channel.
This calculation prevents emotional decisions about ad spend. The numbers tell you whether a campaign is profitable, not your gut feeling.

Frequently Asked Questions
How much should I spend on Google Ads as a small business?
Start with $500-$1,000/month for a single service campaign. This gives you enough data to learn what works within 30-60 days. Most contractors see cost-per-click of $5-$50 depending on industry and location. Once you identify profitable keywords, scale up to $2,000-$5,000/month for faster growth.
Are Google Ads worth it for contractors?
Yes, for most contractors Google Ads deliver strong ROI because they capture people actively searching for help. A plumber spending $1,000/month on ads who lands two $2,000 jobs gets a 4x return. The key is targeting high-intent keywords like 'emergency plumber near me' and using dedicated landing pages, not your homepage.
Google Ads vs Facebook Ads: which is better for small business?
Google Ads are better for emergency and urgent services because they capture people actively searching for help. Facebook Ads are better for planned projects and brand awareness at a lower cost per click ($1-$5 vs $5-$50). Most service businesses should start with Google Ads and add Facebook Ads for retargeting once their budget exceeds $2,000/month.
What is a good cost per lead for a service business?
Cost per lead varies by industry: plumbing and HVAC typically see $30-$75 per lead, remodeling $75-$200, and roofing $50-$150. The real metric to track is cost per acquired customer, which should be less than 10-15% of your average job value. A $100 lead that converts to a $5,000 job is excellent.
Why are my Google Ads not getting leads?
The most common reasons are sending traffic to your homepage instead of a dedicated landing page, targeting broad keywords that attract the wrong audience, not using negative keywords to filter out irrelevant searches, and not tracking conversions. Fix these four issues and most campaigns improve dramatically within 30 days.
