Facebook Ads vs Google Ads: Which Should You Use?
Deciding between Facebook Ads and Google Ads comes down to one question: do you want to reach people who are already searching for what you sell, or introduce yourself to people who don't know you exist yet? Google Ads captures existing demand — someone types "emergency plumber near me" and your ad appears at exactly the right moment. Facebook Ads creates demand — your ad appears in the feed of someone who never searched for you but fits the profile of your ideal customer.
The short answer for most small businesses: if people actively search for your product or service, start with Google Ads. If your product is visual, new, or impulse-friendly — or nobody knows to search for it — start with Facebook Ads. And if you can afford to test both, the two platforms work better together than either does alone. The rest of this guide breaks down when each one wins, what they cost, and how to choose with a limited budget.
Facebook Ads vs Google Ads: The Core Difference
Both platforms are pay-per-click advertising, but they intercept customers at completely different moments.
Google Ads is intent-based. Your ads show when someone searches for keywords you choose. The person has a need right now and is actively looking for a solution. That intent is why Google search clicks convert well — the hard part (wanting the thing) is already done.
Facebook Ads is audience-based. Your ads show to people based on who they are — age, location, interests, behaviours, and lookalikes of your existing customers. They weren't looking for you, so your ad has to earn attention with a strong image or video and a compelling offer. Facebook (and Instagram, which runs on the same Meta ad system) is closer to digital billboard space, except the billboard knows who's walking past.
What Each Platform Costs
Costs vary enormously by industry, so treat any single "average" number with caution. That said, industry benchmark reports are consistent on the general pattern:
- Facebook clicks are cheaper. Meta clicks typically cost a fraction of Google search clicks — often in the range of one to two dollars, and lower for pure traffic campaigns.
- Google clicks cost more but convert more often. Recent WordStream benchmark data puts the cross-industry average search CPC above five dollars, with legal and other professional services costing far more. But average conversion rates on Google search are several times higher than typical Facebook conversion rates, because searchers are further along in the buying process.
- Both platforms get more expensive every year. Benchmark reports across the industry show steady year-over-year cost increases on both platforms, which makes sloppy targeting more punishing than it used to be.
The practical takeaway: don't compare cost per click. Compare cost per customer. A cheap click that never buys is more expensive than a costly click that does.
Side-by-Side Comparison
| Google Ads | Facebook Ads | |
|---|---|---|
| Reaches people who are… | Actively searching | Scrolling their feed |
| Best for | Urgent needs, services, high-intent products | Visual products, new brands, impulse buys |
| Cost per click | Higher | Lower |
| Conversion rate | Higher (intent already exists) | Lower (you're creating intent) |
| Creative needed | Text ads; simple to produce | Strong images or video; creative is everything |
| Targeting based on | Keywords and search intent | Demographics, interests, lookalikes |
| Results speed | Fast — traffic on day one | Slower — algorithm needs a learning period |
| Weakness | Limited by search volume | Ad fatigue; needs fresh creative |
When Google Ads Is the Better Choice
Choose Google Ads first when demand for what you sell already exists and shows up as searches:
- Urgent, need-it-now services. Plumbers, locksmiths, towing, emergency dental. Nobody discovers a locksmith through a Facebook ad at the moment they're locked out.
- High-intent local services. Accountants, lawyers, contractors, clinics. People search, compare, and call.
- Products people search for by name or category. If there's real monthly search volume for your keywords, Google lets you stand directly in front of it.
- B2B with a clear problem. Business buyers research on search engines. A well-targeted search ad meets them mid-research.
The main limitation of Google Ads is that it can't create demand. If only a few hundred people a month search for what you sell, your ceiling is a few hundred people — no budget increase changes that.
When Facebook Ads Is the Better Choice
Choose Facebook (Meta) Ads first when your customer doesn't know they want you yet:
- Visual, impulse-friendly products. Apparel, home decor, food, gifts, beauty. A scroll-stopping video can sell what nobody was searching for.
- New or unfamiliar products. If you invented something, there's no search volume for it. Facebook is how you build awareness from zero.
- Precise audience, low search volume. If your ideal customer is "new parents in a specific region who follow fitness accounts", Facebook can reach exactly them.
- Event promotion and local awareness. Restaurant openings, markets, classes — where geography and interests define the audience better than any keyword.
- Retargeting. Showing ads to people who already visited your website is one of the highest-return tactics on Meta, and it works for any type of business.
The catch: Facebook is a creative game. Weak images and generic copy get scrolled past no matter how good the targeting is, and even strong ads wear out and need refreshing every few weeks.
What About a Small Budget?
With a limited monthly budget, spreading it across both platforms usually means neither gets enough data to perform. Pick one platform and one goal:
- Service business with searching customers → put the whole budget into Google search ads on your highest-intent keywords, restricted to your service area.
- Product business or new brand → put the budget into Meta, starting with one strong video or carousel ad and a simple conversion objective.
- Either way, install tracking first. The Google tag and the Meta pixel are free. Without conversion tracking you're guessing, and both platforms' algorithms optimize far better when they can see which clicks turn into sales or leads.
Give the platform at least a month before judging it. Both ad systems have a learning phase, and week-one results are usually the worst you'll ever see.
The Best Answer for Most Businesses: Both, in Sequence
The strongest advertisers don't treat this as either/or. They use each platform for what it does best:
- Facebook creates demand — introducing the brand to cold audiences with engaging creative.
- Google captures demand — catching those same people days later when they search for you or your product category.
- Retargeting closes the loop — Meta retargeting brings back website visitors who didn't buy the first time.
This is also why running ads works better on a site with solid organic foundations — people who see your ad often search your name before buying, and you want them to find a credible result. If your site isn't ranking for anything yet, our plain-English guide to SEO covers the basics, and pairing paid ads with an organic social media presence makes the ads themselves cheaper: platforms reward businesses that people already engage with.
Quick Decision Checklist
- Do people actively search for what you sell? Yes → Google Ads first.
- Is your product visual or new to the market? Yes → Facebook Ads first.
- Is your budget small? Pick one platform, one goal, and track conversions.
- Already getting website traffic? Add Meta retargeting regardless of which platform you started with.
- Growing and profitable? Run both: Facebook to create demand, Google to capture it.
There's no permanently correct answer — the right platform is the one whose cost per customer is lowest for your specific business, and the only way to know that number is to run a disciplined test and measure it.
