A pipe bursts at 2 a.m., and the homeowner grabs a phone and types “emergency plumber near me.” Nobody in that moment is scrolling Instagram and hoping a plumber floats by.
That scene explains most of the Google Ads vs Facebook Ads debate. Google shows your ad to people who are actively searching for what you sell, while Facebook and Instagram, which Meta runs as one advertising system, show your ad to people who fit an audience you describe as they scroll past friends and news. One platform catches intent, and the other interrupts. Both can work for a service business, but they do different jobs, and most of the wasted ad spend we see comes from asking one platform to do the other one’s job.
Google Ads vs Facebook Ads: The short answer
If people already search for your service, start with Google. If they don’t realize they need you yet, or they buy with their eyes, Meta deserves a bigger share of the budget.
- Google Ads responds to demand that already exists, because your ad appears when users search for specific keywords.
- Meta advertising creates demand, because your ad reaches people based on who they are, what they engage with, and what they’ve done on your website.
A search click arrives with a question to answer, while a Meta click arrives curious and needs more persuading.
The Facebook Ads vs Google Ads question gets easier once you name the job for this quarter: catching buyers who are ready now, or reaching buyers who will be ready later.
How Google Ads works
Google Ads is a search engine auction. Every time someone searches, Google runs a separate auction for each ad location on that results page, and you compete by choosing keywords, writing ads, setting a budget, and picking a bid strategy.
Your bid is only part of the story, because Google calculates a score called Ad Rank to decide whether your ad shows at all and where it lands. According to Google’s explanation of Ad Rank, it rests on six factors: your bid, the quality of your ad and landing page, minimum quality thresholds, the competitiveness of the auction, the context of the search (location, device, time, and the words used), and the expected impact of ad assets like your phone number or additional links.
Google also reports a Quality Score from one to 10 for each keyword. It isn’t an input in the auction, although it shows where your expected clickthrough rate, ad relevance, or landing page experience trails competitors, and a “Below average” landing page rating means the page needs work, which a higher bid won’t fix.
How Facebook and Instagram ads work
Meta also runs auctions, billions of them every day, according to its help center, and the difference is what gets you into each one. On Google, the searcher’s words decide which ads compete, while on Meta you describe who should see the ad, and your ad competes whenever someone in that audience has an open ad slot in their feed, Stories, or Reels.
Meta picks the winner by what it calls total value, which combines your bid, the estimated probability that this person will take the action you want, and ad quality, which Meta judges partly from people who hide your ad or give feedback on it. Meta’s guide to ad auctions says an ad that’s more relevant to a person can win against ads with higher bids, so a clear, honest ad aimed at the right people can win auctions for less money.
On Meta, the creative does much of the targeting work that keywords do on Google, because the delivery system learns who responds, so a video that speaks to one specific person (a new homeowner, a practice manager, a founder with messy books) tends to find more people like them.
Ad types that fit service businesses
Google ad types
- Google search ads are text ads on the results page, and Google describes them as the way to reach people actively searching for your products and services, which makes them the first campaign most service firms should build.
- Local Services Ads appear prominently in Google results for eligible categories, including plumbers, electricians, HVAC, locksmiths, roofers, house cleaning, pest control, and many kinds of lawyers, and you pay for leads that arrive as calls, messages, or bookings.
- Display ads are image ads shown across websites, apps, YouTube, and Gmail, which suit retargeting and brand awareness more than urgent demand.
- Performance Max runs one campaign across Search, YouTube, Display, Discover, Gmail, and Maps, and Google’s AI decides where the money goes, so feed it accurate conversion data or it will cheerfully find you more of the wrong leads.
- Shopping ads are built for physical products, so most service businesses can skip them.
If you run Performance Max alongside search campaigns, Google gives the search campaign priority whenever a query matches one of its exact match keywords. Before building anything, check whether your category and city qualify for Local Services Ads, because the eligible list covers many trades and legal services and leaves out plenty of others.
Meta ad types
- Image ads pair a single photo or graphic with copy, and they’re quick to produce and test.
- Video ads let you show a person doing the work, which is the fastest way we know to build trust for a service nobody can touch before buying.
- Carousel ads show two or more images or videos in one ad, each with its own link, and Meta suggests them for explaining a process step by step.
- Lead ads collect contact details without sending people to your website, through instant forms, call ads, or ads that open a conversation in Messenger, Instagram, or WhatsApp.
Meta may prefill a person’s name, email, and phone number on an instant form, which makes submitting easy. Sometimes too easy. If your team spends Monday calling people who don’t remember filling out a form, switch to the “Higher intent” form type, which adds a review screen so people confirm their information before they submit.
Costs and bid strategy
We won’t quote an average cost per click, because a plumber in a small town and a personal injury lawyer in a major city live in different universes. Both platforms price ads through auctions, so there’s no price list, although both explain what moves the price.
What drives cost per click on Google
- Keyword competition matters most, and Google says that when two ads have similar Ad Rank, the winner may pay a higher cost per click for the certainty of winning, although the actual charge is often below your maximum bid.
- Better ad and landing page quality raises your Ad Rank, so you can hold a position without raising your bid.
- Keyword choice sets the value of each click, since specific keywords like “water heater repair” bring fewer searchers than broad ones like “plumbing,” and a larger share of them are ready to hire.
What drives CPM and cost per lead on Meta
On Meta, two numbers tell the cost story: CPM, which is what you pay for 1,000 impressions, and cost per result, which is what you pay for each lead, call, or booking.
- Audience competition raises prices, because one person can belong to many advertisers’ audiences at once, and the more advertisers want your buyers, the more each impression costs.
- Relevance feeds the auction, so an ad people ignore or hide costs more to deliver.
- Meta’s pacing system holds back budget when auction competition makes results expensive and spends more when results become cheaper.
- New ad sets are less stable and usually have a higher cost per action until they complete what Meta calls the learning phase.
Choosing a bid strategy
Both platforms rely heavily on automated bidding. On Google, Smart Bidding strategies like Maximize conversions and Target CPA set a bid in every auction based on the likelihood that the search will convert. On Meta, the default is highest volume, which spends your budget to get as many results as possible, while a cost per result goal tries to keep your average cost near a target you set.
Automation needs data. Meta recommends 50 to 100 or more weekly conversions for its goal-based bid strategies, and Google suggests evaluating Smart Bidding over a period with at least 30 conversions, such as a month or longer. Most small service firms won’t reach those numbers in the first weeks, so start with Maximize conversions on Google and highest volume on Meta, feed both accurate conversion data, and add cost targets once the volume exists.
Then judge cost effectiveness by cost per qualified lead, and better still, by cost per signed client, because a cheap click that never calls costs more than an expensive click that books a job.
Lead generation and conversion rate
Intent shows up in conversion rate, because someone who searched “commercial roof leak repair” and landed on a page about commercial roof leak repair is halfway to calling, while someone who saw your video between a friend’s vacation photos and a pasta recipe needs more convincing, even after tapping through. Meta leads tend to arrive earlier in the buying process, so plan for that:
- Call Meta leads within minutes, while they still remember the ad.
- Offer something lighter than a sales call, like a checklist, a pricing guide, or a 15-minute assessment.
- Add one or two qualifying questions to the instant form, such as project size or timeline.
- Track how many leads become booked appointments, since that’s where inexpensive leads reveal their true cost.
Google leads need different care. Send each ad group to a landing page that matches the search, keep the phone number tappable on mobile, and answer the searcher’s main questions above the form. Our website redesign checklist covers the landing page and page speed checks that improve conversion rate. With Local Services Ads, responsiveness matters in a literal way, since Google says that if you regularly fail to answer calls or respond to messages, your ad ranking may suffer.
Tracking: Count leads, then count clients
Both platforms will happily report “conversions” that never turn into revenue, and their bidding systems learn from whatever you define as success, so set up tracking before you spend a dollar.
On Google:
- Install the Google tag for form submissions and booked calls, and track calls from your ads with a minimum call length, so a 10-second wrong number doesn’t count as a lead.
- Import offline conversions from your CRM, so Google learns which clicks became paying clients.
On Meta:
- Install the Meta Pixel, which records actions people take on your website, such as submitting a form.
- Add the Conversions API, which sends events from your server or CRM (including qualified leads and signed clients) and which Meta says is less affected than the pixel by browser loading errors, connectivity issues, and ad blockers.
- Connect your instant forms to your CRM, so leads don’t sit unread in Ads Manager for a week.
Add UTM tags to every ad link and review Google Analytics weekly, so both platforms appear in one report, with cost per signed client as the number that matters most.
Brand awareness: Where Meta earns its keep
Search ads can’t create demand. If nobody searches for what you do (say, a fractional CFO service for dental groups), Google has nothing to show your ad against, and that’s the gap Meta and other social media platforms fill. You can put a two-minute video of your founder explaining an expensive problem in front of practice owners across your region, and some of them will search for you by name a month later.
That branded search is where the two platforms meet, so a small branded Google Ads campaign catches those people, and when you evaluate Meta, check branded search volume and direct visits along with the leads Meta reports.
Paid reach works best alongside earned attention, and if you’re weighing advertising against press coverage, our piece on whether PR and advertising are the same thing explains where each one builds trust.
Retargeting on both platforms
Plenty of people read two pages of your website and leave without calling, which is why retargeting exists.
- On Google, “your data” segments (Google’s current name for remarketing lists) show your ads to past visitors as they browse Google and partner sites, or when they search again.
- On Meta, website custom audiences use the Meta Pixel to reach past visitors, and other custom audiences cover people who watched your videos or opened your lead form.
- Meta lets you upload an exclusion-only customer list, so you stop paying to advertise to people who already hired you.
One practical warning: a Meta website custom audience starts collecting people on the day you create it and won’t backfill earlier visits, so install the pixel and build your retargeting audiences on day one, even if you won’t run retargeting ads for a month. Keep the ads themselves useful, because the same “Book now” ad shown 20 times reads as nagging, and people who hide it lower your ad quality in the auction.
Which platform fits your type of service business
Emergency and urgent services
Plumbers, locksmiths, HVAC technicians, roofers after a storm, water damage crews, and criminal defense lawyers all sell to people in a hurry. Put most of the budget into Google, with Local Services Ads if your category qualifies and Google search ads on specific keywords like “burst pipe repair” and “AC not cooling.” Add call assets and call tracking, because these buyers phone first and read later.
Meta’s smaller role here is retargeting and a steady stream of reviews and before-and-after posts, so your name feels familiar when the emergency happens.
Considered B2B services
Accounting firms, managed IT providers, commercial contractors, and consultants sell to buyers who research for weeks and involve several people before they sign. Google search catches the moment a buyer starts looking, so bid on keywords with clear commercial intent, such as “outsourced bookkeeping for law firms,” and add negative keywords to exclude job seekers and students.
Meta handles the slower work, because short videos and client stories keep you in front of the buying committee between searches. Unless you sell software with a free trial, your conversion is usually a booked call, so send CRM stages back to both platforms and optimize toward qualified meetings once you have the volume.
Local consumer services
Med spas, dentists, salons, personal trainers, lawn care companies, and home cleaners sit in the middle, because people search for them (“teeth whitening near me”) and also buy with their eyes. Split the budget. Google search and Local Services Ads, where eligible, capture the searchers, while Meta image, video, and carousel ads show the results, the team, and the space. For these businesses, Meta can work as a lead generation engine on its own, especially around a seasonal offer or a first-visit incentive.
How to run Google Ads and Facebook Ads together
Many service businesses end up on both platforms, and the trick is giving each one a distinct job.
- Let Google capture existing demand with search campaigns on your service and location keywords.
- Let Meta build familiarity with your ideal buyers through video and client stories.
- Run a branded search campaign on Google, so people who saw you on Meta find you first when they look up your name.
- Retarget site visitors on both platforms, and exclude current clients and recent leads from your prospecting ad campaigns.
- Keep the offer, message, and visuals consistent, so the ad on Instagram and the ad on Google look like the same company.
If your ads look like three different companies made them, our rebranding checklist covers fixing that first. And the queries that convert on Google are a ready-made list of pages to build for organic search and AI answers, which is where our SEO and AEO work picks up.
A 90-day starter budget test plan
Most advice on Google Ads for service business owners skips the boring part: what to test, how much to spend, and when to stop. The right budget depends on your client value and your local competition, so start with the math.
Calculate your starting budget
- Estimate what a new client is worth over the first year, and decide what share of that you’re willing to spend to win one.
- Multiply that acquisition cost by your close rate to get the most you can pay per lead, so if you close one lead in four, you can pay a quarter of your target client cost for each lead.
- For Meta, plan enough budget per ad set to reach about 50 results in a week, the point where Meta’s learning phase guide says ad sets usually stabilize, and if that’s beyond your weekly budget, run fewer ad sets.
- For Google, divide your monthly figure by 30.4 to get the average daily budget, as Google instructs, and expect some days to spend up to twice that amount, since Google keeps the monthly total within 30.4 times the daily budget.
Sequence the test over three months
- In weeks one and two, set up tracking on both platforms, build your retargeting audiences, and launch one Google Ads campaign on your highest-intent keywords, plus Local Services Ads if you qualify.
- In weeks three and four, check the search terms report every few days, add negative keywords, and fix any landing page that gets clicks and no leads.
- In month two, launch Meta with one campaign, one audience, and three to five ads (a mix of image, video, and carousel) built around the same offer, and leave it alone while it learns, because Meta says edits during the learning phase reset it.
- In month three, compare cost per qualified lead and cost per signed client across both platforms, cut the weakest ads, move budget toward the winner, and turn on retargeting.
Deciding where to start
If you sell an urgent service, start with Google. If buyers need to see your work before they trust you, give Meta a meaningful share of the budget, and if you’re uncertain, run the 90-day test above and let your own numbers decide.
