Facebook vs Instagram: Which Is Better for Your Small Business?

"Should we be on Facebook or Instagram?" It's the question we get asked most often. The honest answer: it depends on who your customers are, what you sell, and how much time you can realistically commit. Here's how to make a decision based on data rather than guesswork.

Facebook by the numbers. Facebook's organic reach for business pages has dropped to roughly 2.6% to 5.2% of your followers. That means if you have 1,000 followers, somewhere between 26 and 52 people will see your average post without paid promotion. The platform's fastest growing demographic is now users aged 55 and over, while younger users have migrated to Instagram and TikTok. Facebook's strengths lie in its Groups (still unmatched for community building), Marketplace (excellent for local product businesses), and Events (ideal for hospitality and entertainment).

Instagram by the numbers. Instagram's engagement rate averages around 0.50% to 0.70% for most accounts, but smaller accounts (under 10,000 followers) often see rates closer to 1.0% or higher because the algorithm favours accounts with strong relative engagement. Gen Z users are twice as likely to discover new brands on Instagram than on Facebook. The platform rewards Reels heavily, with short form video content receiving significantly more distribution than static images or carousels.

When Facebook is the right choice. Local service businesses (trades, cleaning, gardening) where word of mouth matters. Facebook Groups let you build a local community and become the go-to recommendation. Businesses targeting customers aged 40 and over, who remain Facebook's core audience. Event based businesses like pubs, restaurants, and live music venues where the Events feature drives footfall. B2B services where longer form content and direct messaging work better than visual posts.

When Instagram is the right choice. Any business where the work is visual: food, beauty, fitness, interiors, fashion, photography, floristry. Product based businesses that benefit from Instagram Shopping. Businesses targeting 18 to 40 year olds, particularly women (who make up roughly 57% of Instagram's UK user base). Personal brands and freelancers where showing your personality and portfolio matters.

The case for picking just one. Running both platforms properly takes real time. You need different content for each (a Facebook post with a paragraph of text and a link performs well there but dies on Instagram). You need to engage with comments and messages on both. If you're a small team or a solo business owner, doing one platform brilliantly will always outperform doing two platforms half heartedly. Our recommendation: master one, build a routine, then add the second when you have capacity.

What about TikTok? TikTok's average engagement rate (2.6% to 4.0%) dwarfs both Facebook and Instagram. If your audience is under 40, if you can produce short video content, and if your business has any visual or personality driven angle, TikTok is worth serious consideration. The barrier to entry is lower than you think: raw, unpolished content often outperforms slick production on TikTok.

How to decide in 5 minutes. Answer these three questions. Where do your current customers spend their time online? (Ask them.) What type of content can you create most consistently? (Photos, videos, or written posts.) Is your goal brand awareness or direct enquiries? If your answers point toward community and conversation, start with Facebook. If they point toward visuals and discovery, start with Instagram. If they point toward video and a younger audience, start with TikTok.
