Facebook ads vs Google ads: which is better for small businesses?

It’s the question almost every small business owner asks before spending on ads. The honest answer: it depends on whether your customers are already searching for what you sell. This guide will help you decide in minutes.

The key difference: intent vs discovery

Google ads capture demand. They appear when someone actively searches for something, like “emergency plumber near me” or “buy running shoes online.” The person already has a need and is looking for a solution right now.

Facebook and Instagram ads create demand. They appear while people scroll their feeds. Most viewers weren’t looking for your product, but precise targeting by interests, behaviours and demographics lets you put it in front of people likely to want it.

Side-by-side comparison

When to choose Google ads

• People already search for your service (plumbers, lawyers, dentists, accountants, repair services).
• Your customers have an urgent need.
• You sell well-known products people compare online.
• You want leads quickly from people ready to buy.

When to choose Facebook and Instagram ads

• Your product is new or people don’t know to search for it.
• Your product is visual: fashion, beauty, food, home décor, fitness.
• You sell lower-priced items people buy on impulse.
• You want to build an audience and retarget website visitors.

Why the best answer is often both

The most effective campaigns usually combine the two. Facebook and Instagram ads introduce your brand to new people. Many won’t buy straight away, but they’ll remember you. Later, when they search on Google, your search ad is there to capture the sale. Retargeting ads on both platforms then remind visitors who left without buying.

How much should a small business spend?

Start with a budget you can sustain for at least four to eight weeks, because both platforms need time and data to optimise. It’s better to run one platform well than two platforms with too little budget. Once you know your cost to win a customer, scale what works.

Five mistakes that waste ad budget

1. No conversion tracking. Without it, you can’t tell which ads bring customers.
2. Sending traffic to your homepage instead of a focused landing page.
3. Targeting too broadly on Google, paying for irrelevant searches.
4. Never testing new creative on Facebook, so ads go stale.
5. Stopping too early, before the platforms have enough data to learn.
