TikTok Ads for UK small businesses: a practical guide

TikTok Ads are the fastest-growing ad channel in the UK, but most small businesses either ignore them entirely or throw budget at them without a strategy. Here's how to do it properly.

Is TikTok worth it for UK SMEs?

If your target audience is under 35, the answer is almost certainly yes. TikTok has over 20 million active users in the UK, and its ad costs are still significantly lower than Meta's for comparable reach. The platform rewards creativity over budget — a £20/day campaign with a great native-looking video can outperform a £500/day campaign with a polished corporate ad.

What it costs

TikTok's minimum daily budget is £20 per ad group — lower than Google's typical floor. Average CPMs in the UK run £3–£8 (vs £8–£15 on Meta), and CPCs are typically £0.30–£0.80. For e-commerce and DTC brands, TikTok often delivers the lowest cost per acquisition of any paid channel.

What actually works on TikTok

TikTok is not Facebook. The ads that perform are native, raw and fast. Skip the polished production. The top-performing TikTok ads from UK brands look like user-generated content — vertical, 9-15 seconds, hooking the viewer in the first 2 seconds with a question, a problem or a surprising result. Use TikTok's native text overlays, trending sounds and creator-style editing.

Targeting: broad is better

TikTok's algorithm is remarkably good at finding your audience if you let it. Unlike Facebook, where you layer interests, TikTok's 'Broad' targeting with good creative consistently outperforms narrow interest targeting. The platform learns from who engages and optimises automatically within 24–48 hours.

Measuring TikTok alongside your other channels

The biggest mistake UK businesses make with TikTok is measuring it in isolation. TikTok often starts the customer journey — someone discovers your product on TikTok, then searches for it on Google two days later and buys. If you only track the last click, Google gets all the credit and TikTok looks like it's losing money. You need a unified view that shows every platform's contribution.
