Google Ads catches people who are already looking for what you sell. Meta Ads reaches people who were not looking, but might be interested once you show them. For a service business, that one difference settles most of the Google Ads vs Meta Ads question before you look at a single cost-per-click figure.
The rest of the answer depends on how people find businesses like yours, how you judge a lead, and whether your industry faces special advertising rules.
Google Ads vs Meta Ads: intent versus attention
On Google Search, someone types "accountant for small business near me" or "commercial roof leak repair". They have a problem and are looking for someone to solve it. Your ad is an answer to a question they asked.
On Facebook and Instagram, someone is scrolling past friends' photos and short videos. Your ad interrupts them. That can work very well, but the ad has to create interest rather than meet it.
So the useful question is not "which platform is better?" It is "do enough people already search for what I sell?" If yes, start with Google. If hardly anyone searches for it, Google has little to show your ads against, and Meta is the more natural starting point. Keyword Planner, inside your Google Ads account, shows monthly searches and estimated costs for your keywords before you spend anything, which makes it a quick way to check.
When Google Ads is usually the better first bet
- Urgent needs. Plumbers, locksmiths, towing, emergency dental care, pest control. Nobody scrolls Instagram hoping to find a locksmith.
- Considered purchases that people research. Accountants, lawyers, IT services, business software, home renovation. Buyers search, compare and shortlist.
- Local services with obvious search terms. "Physical therapist in Denver", "AC repair near me", "wedding venue Jaipur".
The trade-off: search volume is finite, and in competitive trades clicks can be expensive. You can only buy as many clicks as there are searches, however much budget you add.
When Meta Ads earns its place
- Services people do not know to search for. A new kind of treatment, a meal subscription, a home energy audit. Demand may exist, but it has not turned into searches yet.
- Visual or emotional offers. Interior design, wedding photography, fitness coaching, cosmetic dentistry. A before-and-after photo does work that a text ad cannot.
- Audiences you can describe but who do not search. People in a particular area with a particular interest, who would respond to the right offer but would never type it into Google.
- Retargeting. People who came to your site from a Google ad and left can be reminded on Instagram a few days later.
The trade-off: Meta leads often need more follow-up, because many of them were not planning to buy anything that day.
Lead quality: the number most comparisons ignore
Both platforms offer forms inside the ad, so people can send their details without visiting your website. Meta's lead ads fill in the form using information people have already shared with Facebook, according to Meta's lead ads documentation. Google offers lead form assets in Search, Performance Max and some Display campaigns. Pre-filled forms make submitting almost effortless, and that is exactly why they can bring in more low-intent leads: people who tapped submit without much thought, or who do not remember doing it when you call.
So cost per lead is a misleading number to compare. Compare cost per qualified lead or, better still, cost per customer. Here is an illustrative month for a home renovation company spending $2,000 on each platform:
- Google Search: 40 leads at $50 each. Sales qualifies 18 and wins 5 jobs. Cost per qualified lead: about $111. Cost per customer: $400.
- Meta lead ads: 110 leads at about $18 each. Sales reaches 60 of them, qualifies 14 and wins 3 jobs. Cost per qualified lead: about $143. Cost per customer: about $667.
On the dashboard, Meta looks almost three times cheaper. In the bank account, Google did better. The numbers are invented, but they show why you should never choose a platform on cost per lead alone. It can go the other way too: a well-run Meta campaign with a qualifying question in the form can beat a Google campaign bidding on vague keywords.
On either platform, lead quality improves when you add one qualifying question to the form, such as budget range, timeline or service area, and when someone calls every lead within minutes, not days, while they still remember who you are.
To get numbers like the ones above, record the outcome of every lead, and ideally send it back to the ad platform so its bidding learns what a good lead looks like. Google's enhanced conversions for leads and Meta's Conversions API both support sending offline results from your CRM back to the platform.

Industry rules that change the answer
Some businesses face advertising restrictions that tilt the choice.
On Meta, ads for housing, employment, and financial products and services fall into special ad categories. For advertisers based in the US, or ads reaching the US, Canada or Europe, these ads cannot be narrowed by gender, age options are generally fixed at 18 to 65+, ZIP codes cannot be targeted, locations need a minimum radius (15 miles or 25 kilometers in the US and Canada, 15 kilometers in Europe), and lookalike audiences are unavailable. A mortgage broker, a recruitment agency or a real estate agent in those markets loses much of Meta's targeting precision, which often makes Google the stronger place to start.
On Google, lead form assets have their own eligibility requirements, including a good history of policy compliance, a business in an eligible category, and a privacy policy linked from the form. Health, legal and financial advertisers should read each platform's policies for their industry before building campaigns, since some claims and targeting options are restricted.
A simple test plan for a service business
If you are still unsure, run a Google Ads vs Meta Ads test, set up so that it produces a clear answer:
- Fix measurement first. Every lead gets a source (Google or Meta) and an outcome (unreachable, unqualified, qualified, won), whether in a spreadsheet or a proper CRM system.
- Start Google on your highest-intent searches: the ones that combine a service with a location, or describe an urgent need. Keep keyword targeting tight at first.
- Run Meta in parallel with one clear offer, such as a free site survey or a first consultation, using an in-ad form with a qualifying question or a fast landing page.
- Give each platform enough budget to produce a meaningful number of leads. A rough rule: budget equals your expected cost per lead times 30. If you expect $40 leads, that is about $1,200 per platform for the test. A handful of leads tells you very little.
- Judge after four to six weeks on cost per qualified lead and cost per customer, not on clicks or cost per lead. If your sales cycle is longer than that, allow more time before deciding.
- Move budget toward the winner, but consider keeping a small Meta retargeting campaign even if Google wins. The audience is small, so the budget can be too.
When neither is the right next step
Paid ads multiply what already exists. If there is no clear landing page, nobody answers the phone during business hours, or leads wait two days for a callback, more traffic just produces more wasted leads. In that case, spend the first month fixing the page and the follow-up process.
And if most of your new customers already come from referrals and repeat business, a small search campaign on your brand name and core service may be all the paid advertising you need for now.
Something to do this week, before any new campaign: pull your last 50 leads, from any source, and mark each one qualified or not. If your records cannot tell you, fix that first, because without it you will never know which platform is working.
If you would like help setting up a fair test between the two, our Google Ads team and Meta Ads specialists can set up the tracking, run both campaigns and go through the results with you, including when the numbers say to spend less rather than more.
