How to Target the Right Audience on Facebook Without Wasting Budget

# How to Target the Right Audience on Facebook Without Wasting Budget

Facebook advertising works. That part's true. But spend £500 on the wrong audience and you've basically set that money on fire. The good news? Getting your targeting right doesn't require a marketing degree—it just requires understanding what actually works in 2024, not what Facebook's sales team told you works.

Over the last five years, Facebook's targeting options have changed dramatically. Some of the old methods don't work like they used to. And there's a genuinely counterintuitive strategy that often beats precise, narrow targeting. Let me walk you through it, with real numbers and examples that apply to UK businesses.

The Four Main Targeting Types (And What They Actually Do)

When you log into Facebook Ads Manager, you'll see several ways to reach people. Here's what each one actually means:

Interest targeting shows your ads to people who've said they're interested in something. If you're a plumber in Birmingham, you could target people interested in "home improvement" or "bathroom design." Facebook knows this because they've browsed related pages, joined groups, or clicked on similar content.

Behaviour targeting is based on what people actually do—not what they say they like. This might be purchase behaviour (people who've bought home improvement products online), device usage, or travel habits. If you run a holiday lettings business, you could target frequent travellers.

Lookalike audiences are Facebook's attempt to clone your best customers. You upload a list of your existing customers (email addresses, phone numbers, or people who've visited your website), and Facebook finds similar people. This is powerful because it's based on real behaviour: the people you've already convinced to buy.

Custom audiences let you directly target people you already know. Visited your website? Already a customer? They go in a custom audience. You literally show ads to people who've already engaged with your business.

Why Detailed Targeting Isn't What It Used To Be

Here's the honest bit: Facebook's detailed targeting has weakened significantly.

In 2018, you could target someone by their job title, income bracket, relationship status, and twenty other data points. It was almost surgical. But privacy regulations—especially GDPR in Europe—forced Facebook to reduce the data it collects and uses for targeting.

In March 2021, Facebook removed hundreds of interest categories related to ethnicity, religion, politics, and sensitive health conditions. Then they quietly weakened interest targeting across the board. Many of the niche interests that used to work brilliantly simply stopped working as well.

What does this mean for you? Targeting 25–35-year-old women interested in yoga who live in South London and earn £40,000+ a year doesn't narrow your audience as much as it used to. Facebook just doesn't have that level of accuracy anymore.

We've tested this repeatedly with clients. A plumber who tries to target only "homeowners interested in bathroom renovation" gets roughly the same result as someone who targets "people aged 25–65 in their postcode area." The detailed targeting adds friction without adding precision.

Why Broad Targeting + Good Creative Often Wins

This is where it gets interesting. The most cost-effective approach for most small businesses is broader targeting combined with genuinely good creative.

Here's why: when you go too narrow, you run out of people to show ads to. A local electrician in Coventry might think "I'll target only men aged 40–60 in my area interested in electrical work." That might be 5,000 people. Show ads to them constantly, and you'll dominate their feed—but you'll also exhaust that audience within two weeks.

A better approach? Target "people aged 25–65 in a 5-mile radius of your postcode" (maybe 50,000 people) and let Facebook's algorithm work out who's most likely to care. Your good creative—a clear before-and-after photo, a customer testimonial, a time-specific offer—does the targeting work for you.

We worked with a local kitchen fitter in Manchester who initially spent £800 on ads targeting "women aged 30–50 interested in interior design and home improvement." He got 3 enquiries. We re-ran the same budget with the same audience size but broader (people aged 25–65 in the area) and significantly better creative: short videos of actual kitchens being installed, real customer reviews, and a clear price guide. He got 8 enquiries.

Same budget. Better creative. Broader audience. Better results.

Why? Because the creative told the story better. People who weren't "interested in interior design" but were thinking about their kitchen renovation clicked anyway. Facebook's algorithm learned who to show it to. You can't be more targeted than the algorithm once it has good data to work with.

When Narrow Targeting *Does* Work

That said, there are situations where you should go specific:

Lookalike audiences nearly always work. If you have 50+ customers and can export their email addresses or phone numbers, upload them to Facebook and create a lookalike audience. Facebook will find people similar to your paying customers. This is gold because it's based on behaviour, not guesswork.

Custom audiences work when you have an email list. If 200 people have already visited your website, show them ads again (but different ads—don't just repeat yourself). They've already shown interest. They're much more likely to convert.

Local targeting is essential. If you're a local business, don't go broad geographically. A hairdresser in Aberdeen doesn't benefit from being seen in Cornwall. That's not narrow targeting—that's just not wasting money.

A Practical Example: How BrightClick Would Approach This

Let's say you run a carpet cleaning business in Leeds. Here's what actually works:

1. Start with a lookalike audience. If you've had 30+ customers in the last year, upload them. Target the lookalike audience (roughly 1% of similar people in the UK, usually 100,000+ people). Budget: £300–500 for your first test.

2. Create one piece of strong creative. A short video of a heavily stained carpet becoming spotless. Or before-and-after photos. 30 seconds maximum. Mention your local area and your price point.

3. Run it for two weeks. See what your cost per enquiry is. If it's under £20 per enquiry and you charge £100+ per job, you're winning.

4. Add a custom audience. Target people who've visited your website but haven't booked. Show them a different ad—maybe a customer review or a special offer.

If the lookalike audience works, you can scale it. If it doesn't, you've only spent £500 learning that your creative or pricing isn't resonating. That's information worth having.

What Small Business Owners Should Actually Do

Here's what I'd recommend, in order:

• Don't overthink targeting at first. Set a small budget (£200–300), pick your local area and a sensible age range, create one good ad, and see what happens. You'll learn more from real data than from theorising.

• Test lookalike audiences before anything else. They work more reliably than manual targeting, especially for local businesses that have been operating for a few years.

• Assume you'll waste 10–15% of your budget learning. That's normal. It's not a failure.

• Get your creative right. Spend more time on your ad's image or video than you do on your targeting settings. People skip ads because they're bored, not because of your targeting.

• Review results after two weeks. Don't panic after three days. If you're paying £15 for an enquiry and your margins support it, you're doing fine.

The Bottom Line

Detailed Facebook targeting used to be your competitive advantage. It isn't anymore. The platform's changed. Privacy laws have changed. What works now is smart audience selection (lookalike audiences, custom audiences, basic location targeting) combined with creative that actually speaks to people.

Your budget isn't wasted because your targeting is too broad—it's wasted when your creative is weak or your offer doesn't match what you're showing. Fix those, and you'll be ahead of most small businesses already.

If you need a second pair of eyes on your Facebook strategy or you're not sure where to start, BrightClick helps local businesses in the UK get this right. But the most important thing you can do today? Create one genuinely good ad and test it on a small budget. You'll know in two weeks whether you're on the right track.
