The two paid search options for local service businesses look similar from the outside — both appear at the top of Google when someone searches "plumber near me." Underneath, they're built completely differently, charge differently, and produce different lead quality. Most operators run them with no clear strategy and waste 30–50% of the spend in the first six months. This is the framework to pick one or both, and run them well.
The 30-second difference
Local Service Ads (LSAs) are pay-per-lead. Google charges you only when a customer calls or messages you through the ad. They show at the very top of search, above regular Google Ads, with photos and the Google Guaranteed badge. To run them, you have to complete a verification process — license check, insurance check, background checks for the owner and field staff.
Google Ads (the "Search Network") is pay-per-click. You bid on keywords; you pay every time someone clicks your ad whether they call you or not. They appear below LSAs but above the organic map pack. There's no verification required.
Both are useful. They're not interchangeable.
The honest pros and cons
Local Service Ads — pros
- Pay-per-lead, not per-click. No money wasted on tire-kickers or accidental clicks. Most trades end up paying $25–$120 per actual lead.
- Top of page placement. Above Google Ads, above the map pack. Highest visibility you can buy.
- Google Guaranteed badge. Adds trust, lifts conversion noticeably for jobs over $1,000.
- Lead disputes work. If a lead is clearly bad (wrong service, wrong area, fake), you can dispute and Google refunds.
- Less optimization needed. You don't manage keyword bids, ad copy, or landing pages. Set service categories, ZIP codes, hours, and budget.
Local Service Ads — cons
- Limited categories and geos. Not every trade has LSA support in every market. Check before you build a strategy on it.
- Less control over bids and which leads you get. Google's ranking algorithm decides who sees your ad. You can influence with reviews, response time, and budget — but you don't pick.
- Verification takes 2–6 weeks. Background checks aren't fast. Plan for it.
- Reviews matter a lot. LSA ranking is heavily review-weighted. Brands with under 25 reviews are at a meaningful disadvantage.
- Response time is enforced. Slow to answer = your ad shows less. The platform actively ranks responsive businesses higher.
Google Ads — pros
- Total control. You pick exact keywords, geo radii, time-of-day schedules, ad copy, and landing pages.
- Captures searches LSAs miss. Informational queries ("how much does an AC unit cost"), comparison searches ("Trane vs Carrier"), branded competitor searches.
- Available everywhere. Every category, every market.
- Better tracking. Conversion tracking, attribution, and analytics integration are far richer than LSAs.
- Useful for non-emergency lead gen. If you're booking maintenance plans, financing, or non-urgent jobs, Google Ads can target those audiences specifically.
Google Ads — cons
- Pay per click. Bad clicks still cost. Most trades waste 20–40% of spend on unqualified clicks if the campaign isn't tightly built.
- Higher cost-per-acquired-job, usually. CPC for "emergency plumber" can hit $50+ per click in competitive cities. At a 10% click-to-lead rate, that's $500+/lead.
- Requires real optimization. Negative keyword lists, landing page testing, ad copy iteration. Not "set and forget."
- Below LSAs in placement. If LSAs are present in your category, you're competing for the second-tier spot.
- Mobile experience matters more. Most local service searches are mobile. If your service pages aren't fast and mobile-first, you'll waste budget on bounces.
What you'll actually pay
Rough cost-per-lead ranges for trades in mid-to-large US markets:
- Plumbing — LSA: $30–$70/lead · Google Ads: $80–$200/lead
- HVAC — LSA: $40–$80/lead · Google Ads: $90–$250/lead
- Roofing — LSA: $50–$120/lead · Google Ads: $100–$300/lead
- Electrical — LSA: $25–$60/lead · Google Ads: $50–$150/lead
- Restoration — LSA: $60–$120/lead · Google Ads: $150–$400/lead
Your numbers will depend on market competition, your reviews, and (huge factor) your booking rate on the leads you receive. A business that books 40% of inbound LSA leads has a fundamentally different economics than one that books 15%, even at identical ad costs. That's why we always tell operators to fix the leak side of the funnel before scaling ad spend — try the free Lead Leakage Calculator to see what you might be losing on inbound leads you already have.
The decision rule
Honest framework, ordered by what's worked across audits:
- If your category has LSAs, start there. Lower cost per acquired job for most trades, faster to set up, less day-to-day management.
- Get to 25+ reviews and a 4.7+ rating before scaling LSA budget. Below that, your impressions are too low to justify the budget.
- Add Google Ads once you've maxed LSA volume — i.e., raising LSA budget no longer increases lead count. That's your saturation point in your geo.
- Run Google Ads for niches LSAs don't cover: long-tail informational ("how to fix a sump pump"), commercial services not in LSA categories, or specialty work where you want very specific keyword control.
- Keep both running once you cross ~$5K/month combined. The portfolio is more stable than either channel alone, and the data improves both.
Five common mistakes
1. Running both at the same time without separating budgets. Cannibalization is real. If you're running both, separate the keyword targeting (LSAs cover branded categories; Google Ads covers long-tail and informational queries) and split the budget so you can compare cost-per-acquired-job.
2. Not enabling lead disputes on LSAs. Google credits clearly bad leads, but only if you flag them. Most operators don't. Build it into your weekly process — review the previous week's leads on Tuesday and dispute the obvious ones.
3. Pointing Google Ads at the homepage. Generic homepage lands convert at 2–4%. Dedicated service-specific landing pages convert at 6–15%. The math compounds — every CPC dollar you spend pointing at a generic page is partially wasted.
4. No after-hours coverage. 30–45% of inbound leads come outside business hours. If those leads ring out or sit overnight, your effective cost-per-acquired-job doubles. Cover after-hours before scaling either channel.
5. Scaling spend without fixing the funnel underneath. Doubling ad spend on a funnel that converts 15% of leads is just doubling waste. Get conversion to 30%+ first, then scale. The economics flip.
Mini-comparison: same brand, both channels
A mid-market HVAC operator we worked with last year ran both channels at $4K/month each for a quarter. The numbers, smoothed across the 90 days:
- LSAs: 87 leads at $46 average · 38 booked jobs at 44% close rate · cost-per-job $105 · avg job value $1,420
- Google Ads: 43 leads at $93 average · 16 booked jobs at 37% close rate · cost-per-job $250 · avg job value $1,380
LSAs delivered ~2× the booked jobs at less than half the cost-per-job. Google Ads still produced revenue, but on a slower cycle and at a higher cost. The right move was scaling LSAs harder and reallocating Google Ads spend to specific commercial-service campaigns the LSAs didn't cover.
Common questions
How long does Google Guaranteed verification take? 2–6 weeks. License and insurance go fast; background checks for the owner and field staff are the slowdown.
Do reviews from other platforms count for LSAs? Only Google reviews. Yelp, Facebook, BBB, and Angi reviews don't feed LSA ranking.
Can I pause LSAs on weekends? Yes, you can set hours by day. Most trades benefit from running them weekends — that's when emergency demand peaks for plumbing and HVAC.
Should I bid on my own brand name in Google Ads? Usually yes if competitors are bidding on your name. If they're not, organic plus your LSA covers it for free.
If you want help deciding between LSAs and Google Ads, or want a written audit of your current paid setup, the Revenue Recovery Audit includes a paid-media review across both channels. Or run the Lead Leakage Calculator first — most operators discover the funnel leaks downstream of paid are bigger than the channel choice itself.
