Facebook Ads vs Google Ads: Which Is Better for a Small Business?
Facebook ads or Google ads? A plain English comparison for small businesses: how each works, which suits your business, and how to test without wasting money.
The short answer: Google Ads is usually better when people already search for what you sell (plumbers, dentists, lawyers, repairs), because you reach them at the moment they’re looking. Facebook and Instagram ads (Meta ads) are usually better for creating demand for things people don’t search for, or for visual products and offers, because you reach people based on who they are and what they’re interested in.
Many small businesses do best starting with one, proving it works, then testing the other. This guide explains how each platform works, which suits which businesses, and how to run a small test without wasting your budget.
The key difference: intent vs interest
| Google Ads (search) | Facebook and Instagram ads | |
|---|---|---|
| How people find you | They search for something | They’re scrolling and see your ad |
| Mindset | Looking to solve a problem now | Browsing, not actively shopping |
| Targeting | Keywords people type, plus location | Location, age, interests, behaviors, lookalikes |
| Best at | Capturing existing demand | Creating new demand and awareness |
| Ad format | Mostly text in search results | Images, videos, carousels |
| You usually pay | Per click | Per impression or click, depending on settings |
Think of Google as a shop counter where people ask for what they need, and Facebook as a local market where you catch people walking past.
When Google Ads is usually the better choice
- Urgent services: emergency plumber, locksmith, towing, roof leak, broken windscreen
- Services people research before buying: dental implants, accountants, solicitors, kitchen renovations
- Anything people type into Google with clear buying intent, like “book a [service] near me”
- Local service businesses where customers compare a few options and call
For many home service businesses, Google’s Local Services Ads are also worth comparing. You pay per lead rather than per click.
What Google Ads needs to work
- A focused list of keywords that show real buying intent
- Negative keywords to block irrelevant searches (like “jobs”, “salary”, “DIY”)
- A landing page that matches the ad and makes contacting you easy
- Conversion tracking, so you know which clicks turn into calls and forms
Without these, it’s easy to spend money on clicks that never turn into customers.
When Facebook and Instagram ads are usually the better choice
- Visual businesses: restaurants, cafés, salons, home décor, fitness, events
- Offers and promotions: a new menu, a seasonal deal, an opening
- Products people don’t search for until they see them
- Building awareness in a local area before people need you
- Retargeting: reaching people who already visited your website
What Facebook and Instagram ads need to work
- Eye-catching images or short videos (real ones usually beat polished stock content)
- A clear, simple offer or message
- Sensible local targeting
- A way to measure results: the Meta Pixel on your website, or lead forms within the platform
Which is cheaper?
It depends entirely on your industry, location and competition. Clicks for competitive local services on Google can be expensive. Facebook can reach lots of people cheaply, but fewer of them are ready to buy.
The only number that matters is cost per customer:
Total ad spend ÷ number of new customers from the ads
Track that for each platform, and you’ll know which is better for your business.
How to test without wasting money
- Pick one platform first, based on the guidance above.
- Fix the basics before spending: a clear landing page, a tappable phone number, a working form.
- Set up tracking: conversion tracking in Google Ads, or the Meta Pixel and lead tracking on Meta.
- Start with a small, fixed budget you’re comfortable losing while you learn.
- Run it for long enough to get real data. A few days isn’t enough.
- Track every enquiry to a sale. Ask callers how they found you.
- Keep what works, cut what doesn’t, then test the other platform.
Common mistakes
- Boosting random Facebook posts without a clear goal or audience
- Sending Google Ads traffic to your homepage instead of a page about the specific service
- Broad keywords that match unrelated searches
- No tracking, so you can’t tell what’s working
- Giving up too early, or the opposite, running ads for months without checking results
- Ignoring free options first, like your Google Business Profile and reviews
Should you run ads at all?
Ads are a great way to get customers quickly, but they stop working the moment you stop paying. Before you spend, make sure you’ve covered the free basics:
- A complete Google Business Profile
- A steady flow of reviews
- A website that clearly explains your services and makes contact easy
These also make your ads perform better, because people who click will trust what they see. For more free ideas, see how to get more customers for your small business.

Frequently asked questions
How much should a small business spend on ads to start?
There’s no universal number. Start with an amount you’re comfortable treating as a learning cost, run it long enough to collect real results, and judge it on cost per customer. Increase spending only on what’s clearly working.
Is boosting a Facebook post the same as running an ad?
Boosting is a simple form of advertising, but it gives you fewer options for targeting, goals and tracking than setting up a campaign in Meta’s Ads Manager. It can work for promoting a post to local people, but for leads or sales, a proper campaign with a clear goal usually performs better.
Do I need a website for Google Ads?
For standard search ads, yes, you need a page to send people to, and a good landing page makes a big difference to results. Google also offers call-focused options and Local Services Ads, which don’t depend on a website in the same way.
Can I run both at the same time?
Yes, and many businesses do. A common approach is Google Ads to catch people who are actively searching, plus Facebook or Instagram retargeting to remind website visitors who didn’t get in touch the first time. Just track each one separately so you know which is paying off.
Should I hire someone to manage my ads?
If your budget is meaningful and you don’t have time to learn, a specialist can save money by avoiding common mistakes. Ask how they’ll track enquiries and customers, not just clicks, and make sure you own the ad accounts.
Summary
- Google Ads catches people already searching; Facebook and Instagram reach people who aren’t searching yet.
- Service businesses with urgent or researched services usually start with Google.
- Visual, offer-led and awareness-focused businesses often start with Meta.
- Judge both on cost per customer, not cost per click.
- Fix your basics first, start small, track everything.
