Facebook and Instagram ads work on a completely different principle to Google Ads: they interrupt people who weren't looking for you, rather than catching people who were already searching. That's their biggest weakness and, used properly, their biggest strength. Here's how Meta advertising actually works, what a realistic budget and timeline look like, and which small businesses genuinely get results from it.
How Meta ads actually work
Facebook and Instagram ads are both bought and managed through the same platform, Meta Ads Manager, structured in three layers:
The platform then serves your ads to people within the audience you've defined who it predicts are most likely to take the action tied to your chosen objective, learning and adjusting delivery over the life of the campaign.
- Campaign — where you set the overall objective: awareness, traffic, leads, sales, and so on. This choice shapes how Meta's delivery algorithm optimises everything underneath it.
- Ad set — where you define the audience (location, age, interests, behaviours, or a custom list of existing customers), the budget, and the schedule.
- Ad — the actual creative: the image or video, the text, and the call to action people see in their feed or Stories.

Realistic budgets and timelines
A genuinely useful test budget for a local small business starts at around £10-£20 a day, run for at least three to four weeks. Anything shorter or smaller rarely gathers enough data for the algorithm to find its footing, and the first week or two of any campaign should be treated as a learning period rather than a verdict on performance.
It's also worth being realistic about what a first campaign should be judged on. Early results are about learning which audiences, creative and offers get any traction at all — the profitable, scaled version of a campaign almost always looks different from what launched in week one.

Boosting a post vs running a proper campaign
The "Boost Post" button on a business's Facebook or Instagram page is quick, simple, and generally the least effective way to spend ad money. It offers a stripped-down version of targeting and objectives, and typically optimises for engagement rather than genuine business outcomes like leads or sales.
Campaigns built properly in Ads Manager give access to the full range of objectives, detailed audience building, split-testing between creative variants, and — critically — proper conversion tracking. The difference in results between a boosted post and an equivalent budget run as a real campaign is usually substantial. If social advertising is worth doing at all, it's worth doing through Ads Manager rather than the boost button.

The Meta pixel, conversions and consent
The Meta pixel (or, more recently, the Conversions API) is a small piece of tracking code that reports back to Meta when someone who saw or clicked an ad goes on to take an action on your website — filling in a form, making a purchase, calling a number set up with click tracking. Without it, Meta has no way of knowing whether a campaign is actually generating business outcomes rather than just clicks.
Because this involves tracking individual visitor behaviour, it falls under the same consent requirements as other analytics and marketing tools — pixel-based tracking generally shouldn't fire until a visitor has given consent through your cookie banner. This is exactly the same territory covered in our guide to GDPR and cookie consent, and it's worth getting right before launching, both for compliance and because inconsistent consent handling quietly damages the accuracy of the very data you're trying to optimise against.

What makes good creative for a small local business
Meta is a visual, scroll-past-in-a-second environment, and creative quality has an outsized effect on results compared with search advertising. What tends to work for a small local business:
- Real photos and short videos of the actual business, staff, premises or work — genuinely outperforming stock imagery, which people scroll straight past.
- A clear, specific offer or hook in the first line of text, since most of the copy is truncated unless someone taps "see more".
- Simple, benefit-led messaging rather than a full sales pitch — the ad's job is to stop the scroll and generate interest, not close the sale on its own.
- A landing experience that matches the ad — sending someone to a generic homepage after a specific offer loses a large share of the interest the ad just created. This is where copywriting that actually converts on the receiving page matters as much as the ad itself.
Which businesses do well — and which don't
Meta ads suit visual, impulse-friendly and locally social businesses particularly well: hospitality, salons and beauty, retail, events, fitness and classes. These are purchases people are happy to be introduced to while browsing, where a good photo or offer can genuinely prompt a decision that wasn't there five minutes earlier.
Emergency and high-intent trades — a burst pipe, a broken boiler, an urgent legal need — usually do far better on search advertising, because the customer already has a defined need and is actively looking for a solution right now. Interrupting someone's Instagram feed with a boiler advert rarely lands with anyone except the small number who happen to need one that exact week.

How it complements search rather than replaces it
The useful way to think about the two channels is demand capture versus demand creation. Google Ads and search generally capture demand that already exists — someone typing "plumber near me" has already decided they need a plumber. Meta ads create or surface demand that wasn't actively being searched for — someone scrolling Instagram who wasn't thinking about redecorating until a nice photo of a finished kitchen changed that.
Our guide to whether to start with Google Ads or SEO covers the search side of that decision in more depth; for businesses with the right kind of visual, browsable offer, running both channels together — search for the people actively looking, Meta for building broader awareness and reaching people before they start looking — tends to outperform relying on either alone. If you'd rather have this built and managed properly than guessed at through the app on your phone, it's the kind of work covered by our paid advertising service.

Common questions
How much should I spend on Facebook ads to start?
£10-£20 a day for at least three to four weeks is a realistic minimum for a local small business. Anything less and the campaign never gathers enough data to optimise against.
Are Facebook ads better than Google Ads?
They're different. Google catches people actively searching for what you sell; Meta puts you in front of people who fit your customer profile but weren't looking. Demand capture versus demand creation.
Do I need to boost posts or run proper campaigns?
Boosting is quick but blunt. Campaigns built in Ads Manager give you proper objectives, audiences and conversion tracking, which is where the results actually come from.
Which small businesses do best on Meta ads?
Visual, impulse-friendly and locally social businesses — hospitality, salons, retail, events, fitness. Emergency and high-intent trades usually do better on search.
