Facebook Ads vs Google Ads: Which Is Better for Small Businesses?

They're both "ads." But they work completely differently.

This is one of the most common questions we get from small business owners. And the answer isn't "both" — at least not at first.

The truth is, Facebook (Meta) Ads and Google Ads attract customers in fundamentally different ways. Choosing wrong means burning money. Choosing right means getting leads for a fraction of what your competitors pay.

Google Ads: Catching People Who Are Already Looking

When someone types "emergency plumber near me" into Google, they have a problem right now and they want it fixed. Google Ads puts you in front of these people at the exact moment they're searching.

This is intent-based advertising. The person has already decided they need something. You're just making sure they find you.

Best for:

• Service businesses (plumbers, accountants, solicitors, dentists)
• Anything people actively search for when they need it
• High-value services where one customer is worth hundreds or thousands
• Local businesses targeting their area

Facebook/Meta Ads: Creating Demand From Scratch

Nobody opens Facebook or Instagram thinking "I need a new kitchen." But if you show them a stunning before-and-after of a kitchen renovation with a compelling offer, suddenly they're interested.

This is interruption-based advertising. You're reaching people who weren't looking for you, but might want what you offer once they see it.

Best for:

• Visual products and services (interior design, fashion, food, fitness)
• Brand awareness for new businesses
• Offers and promotions (flash sales, seasonal deals)
• Building an audience over time
• E-commerce products under £100

The Quick Decision Framework

Ask yourself one question: Are people actively searching for what I sell?

If yes → Start with Google Ads. If no → Start with Facebook Ads. If both → Start with whichever has the clearest path to measuring results.

Why Not Both?

You can run both eventually. But splitting a small budget across two platforms means you don't get enough data on either to optimise properly.

If you've got £1,000/month, putting it all into one platform will get you better results than splitting £500/£500. Once you've got one platform working profitably, then expand to the other.

The Costs Compared

Google Ads:

• Higher cost per click (£1–£10+ depending on industry)
• Higher intent — clicks are more likely to convert
• Typical conversion rate: 3–8%
• You pay per click

Facebook/Meta Ads:

• Lower cost per click (£0.30–£2 typically)
• Lower intent — people are browsing, not searching
• Typical conversion rate: 1–3%
• You pay per impression or per click

So Google clicks cost more but convert better. Facebook clicks cost less but need more warming up. The cost per lead often ends up similar — it's the buying journey that differs.

The Tracking Problem

Both platforms will tell you they're responsible for every conversion you've ever had. They're both lying.

The single most important thing you can do before running any ads is set up proper, independent tracking. Google Analytics with UTM parameters, conversion tracking on your actual enquiry form, and ideally call tracking if phone calls are important.

Without this, you're letting the ad platforms grade their own homework.

Common Mistakes We See

On Google Ads: Running broad match keywords with no negatives, sending traffic to the homepage, no conversion tracking. We see this in about 80% of accounts we audit.

On Facebook Ads: Targeting too broad, no retargeting pixel installed, creative that looks like stock photography, and boosting posts instead of running proper campaigns through Ads Manager.

The Bottom Line

Neither platform is "better." They're different tools for different jobs. The right choice depends on your business, your customers, and how they buy.

If you're not sure which one suits your business, start with the data you have. And if you don't have data yet, that's the first problem to solve.
