Search Google for "plumber near me" and you'll see two different kinds of paid results stacked at the top. First, a row of business cards with photos, star ratings and a green "Google Guaranteed" badge: those are Local Services Ads. Below them, text ads with headlines and descriptions: that's Google Ads. Both put you in front of someone searching right now. They work completely differently, and choosing the wrong one first is one of the most common ways local businesses waste their first marketing budget.
How each one charges
Google Ads charges per click. You bid on keywords, someone clicks your ad, you pay whether or not they become a customer. You control the keywords, the message, the landing page and the targeting. Cost per click ranges from under a dollar to well over a hundred depending on the industry and the market.
Local Services Ads (LSAs) charge per lead. A lead is a call, message or booking that comes through the ad. You set a weekly budget and Google shows you to searchers in your area. You don't choose keywords or write headlines; Google matches you based on your service categories and profile. Leads that don't qualify, wrong service, wrong area, spam, can be disputed and credited back.
Who qualifies
Google Ads is open to essentially any legitimate business. LSAs are limited to categories Google supports, mostly home services, professional services such as law, real estate and financial planning, and a growing list of others including many auto, health, wellness and education businesses. Eligibility requires verification: business registration, licensing where applicable, insurance, and background checks for the owner and often field staff. The process takes days to weeks and is where most businesses give up.
Where each one wins
| Google Ads | Local Services Ads | |
|---|---|---|
| Position | Below LSAs, above organic | Very top of the page |
| You pay for | Clicks | Leads |
| Control | Full: keywords, copy, pages, audiences | Limited: categories, area, budget, profile |
| Trust signals | Ad extensions, reviews if configured | Google Guaranteed badge, rating, response time |
| Best for | Any business; complex offers; high-value B2B; e-commerce | Eligible local service businesses with good reviews |
| Weakness | Waste from broad keywords and poor tracking | Bad leads if unmanaged; ranking depends on reviews and responsiveness |
What decides LSA ranking
Because you can't bid your way to the top in the normal sense, LSA rank is driven by review count and rating, how fast you respond to leads, how many leads you mark as booked versus disputed, your proximity to the searcher, and your budget relative to demand. A business with 200 reviews and a two-minute response habit will beat a business with 12 reviews and voicemail, regardless of who set the bigger budget. This makes LSAs a reputation product disguised as an ad product.
The decision framework
- Check eligibility. If your category isn't supported, the decision is made: Google Ads.
- Count your reviews. Under 20 Google reviews, LSAs will struggle to rank and each lead will cost more. Run Google Ads first while a review program builds volume, then add LSAs.
- Assess your response habits. If calls go to voicemail during the day, LSAs will punish you and Google Ads will waste clicks. Fix response first (see our article on speed to lead) or build automation that does.
- Look at your offer. Simple, urgent, local services (repair, emergency, installation) suit LSAs. Considered purchases, custom quotes, B2B and anything needing explanation suit Google Ads, where you control the message and the page.
- Run both when you can. The businesses that dominate a local search page hold an LSA slot, a Google Ads slot and a map-pack organic slot. Three of the first six results with your name on them is a different kind of market share.
Illustration: an HVAC company launching paid search
A two-truck HVAC company with 35 Google reviews and a receptionist during business hours wants leads before the summer rush. The audit says: eligible for LSAs, review count adequate, response gap after 5 p.m. The plan: launch LSAs first for emergency and repair categories, add missed-call text-back so evening leads get answered, and start a Google Ads search campaign two weeks later for higher-value installation and replacement keywords with a dedicated landing page. LSAs carry the urgent, high-intent volume at a predictable cost per lead; Google Ads carries the considered, high-ticket work where messaging matters. Both report cost per booked job, and budget shifts monthly to whichever is producing it cheaper.
The mistakes we see most
- Setting up LSAs and never disputing bad leads, then concluding "LSAs don't work."
- Running Google Ads on broad-match keywords with no negative keyword list, then paying for searches like "plumber salary."
- Sending Google Ads clicks to the homepage instead of a page that matches the ad.
- Measuring both by clicks or leads rather than by booked, paying customers.
- Treating them as competitors rather than as different positions on the same page.
Setting up LSAs without losing your mind
The verification process is where most businesses stall, so here is what to have ready before you start: your business license number and expiration, general liability insurance certificate with limits, the legal business name exactly as registered, the owner's identification for the background check, and a list of every employee who enters customer homes, because Google's screening partner will check them too. Expect two to four weeks. Set the profile up fully while you wait: every job type you actually want, your real service area (not the whole state), real photos, and hours that match your phone coverage. When the badge appears, you want to be ready to rank, not to start filling in fields.
Google Ads account structure that doesn't leak
For a local service business, the structure that holds up best is simple: one campaign per major service (repair, installation, maintenance), each with tight ad groups by intent, exact and phrase match keywords, a shared negative keyword list that grows every week, and a dedicated landing page per campaign. Location targeting set to "presence" rather than "presence or interest," so you're not paying for someone in another state researching your city. Conversion actions defined as calls over thirty seconds and forms that clear the spam filter, with offline conversions imported from your CRM when a lead becomes a customer. That last step is what lets Google's bidding optimize toward paying customers instead of anyone who fills in a form.
How to read the two side by side
Put them on one page every month with the same columns: spend, leads, qualified leads, booked jobs, cost per booked job. LSAs will usually show a lower cost per lead and a lower lead quality; Google Ads will show the reverse. The number that decides budget is the last column. When one channel's cost per booked job climbs above the other's for two months running, money moves. When both are producing below your target, both scale until they don't. Simple, boring and effective, which is exactly how paid search should feel once the setup is right.
A word on Performance Max and the map
Google will push you toward Performance Max campaigns because they're easy to spend on. For most local businesses they belong after Search is dialed in, not before, and only with strong conversion data to learn from. Meanwhile, remember the third slot on the page: the organic map pack under the ads. LSAs and Google Ads can both be turned off; the map ranking you build through your Google Business Profile and reviews can't be. The complete play is all three, and the review program that feeds LSA rank also feeds the map.
Whichever you run first, the report should say the same thing every month: how many leads, how many became customers, and what each customer cost. That's the only comparison that matters, and it's the one most agencies never show you.
