How to Advertise on Facebook: A Guide for UK Businesses

With over 35 million UK users, Facebook remains one of the most powerful advertising platforms available to British businesses. Its audience spans every age group, interest, and profession, and its targeting capabilities are among the most sophisticated of any advertising platform.

Yet many UK business owners find Facebook advertising frustrating — they boost a post, see little return, and conclude that Facebook ads ‘don’t work’. The truth is that Facebook advertising does work, but it requires more than a boosted post. This guide walks you through how to advertise on Facebook properly, from the basics of Meta Ads Manager to effective targeting and measuring your results.

Getting Started With Meta Ads Manager

Facebook advertising is managed through Meta Ads Manager (formerly Facebook Ads Manager). To access it, you need a Facebook Business account — separate from your personal profile — and a Facebook Page for your business. If you haven’t already, set these up at business.facebook.com.

Inside Ads Manager, campaigns are structured across three levels: the campaign (where you choose your objective), the ad set (where you define your audience, budget, and schedule), and the ad itself (the creative — image, video, or copy). Understanding this hierarchy helps you organise your advertising logically and makes testing easier.

Before you create your first ad, install the Meta Pixel on your website. This is a snippet of code that tracks visitor behaviour and enables you to measure conversions, build custom audiences, and run remarketing campaigns. Without the Pixel, your ability to optimise campaigns is severely limited.

Choosing the Right Objective and Audience

Facebook’s campaign objectives broadly fall into three categories: awareness (reach and brand recall), consideration (traffic, engagement, video views, lead generation), and conversion (purchases, enquiries, store visits). Choose the objective that most closely matches what you actually want to achieve — the algorithm will optimise your ads accordingly.

For most UK small businesses, ‘Leads’ or ‘Conversions’ objectives deliver the best return, because you’re telling Facebook to find people most likely to take a meaningful action. Avoid ‘Engagement’ campaigns if your goal is sales — likes and comments don’t pay the bills.

Facebook’s audience targeting options include location (UK-wide or by town and radius), age, gender, interests, behaviours, job titles, and more. You can also upload a customer list to create a ‘Custom Audience’, or ask Facebook to find people similar to your existing customers using ‘Lookalike Audiences’. Start with a defined audience rather than leaving targeting broad — broad targeting works best with large budgets and advanced conversion data.

Creating Effective Facebook Ads

Facebook is a visual platform, and your creative is the single most important variable in your campaign’s success. High-quality images and short videos consistently outperform text-heavy ads. Use eye-catching visuals that stop the scroll, and pair them with copy that speaks directly to your audience’s needs or desires.

Your ad copy should lead with the benefit, not the feature. Instead of ‘We offer professional accountancy services’, try ‘Stop spending evenings on your accounts — hand them to the experts’. Address a pain point and offer a clear solution. End with a strong call to action that tells people exactly what to do next.

Test multiple ad variations — different images, different headlines, different calls to action — and let Facebook’s algorithm identify which performs best. Running at least two or three creative variations per ad set gives you much more useful data than running a single ad.
