Should Your Business Advertise on TikTok?
TikTok has grown into one of the largest and most engaged platforms in the UK, and its audience now spans well beyond teenagers into millions of adults with real spending power. For the right business, TikTok Ads offer reach and engagement at a cost that is genuinely hard to match elsewhere.
TikTok suits businesses that can tell a visual, entertaining or demonstrable story, consumer products, food and drink, fashion, beauty, travel, apps, and increasingly local and considered purchases too. It is less suited to dry, purely rational B2B (that is LinkedIn's territory), though even B2B brands are finding an audience with the right creative.
The platform rewards authentic, native content over polished corporate ads, which levels the playing field for smaller businesses. This guide covers how TikTok advertising works, formats, costs, and what makes it convert, so you can decide if it fits and run it well.
How Do TikTok Ads Work?
TikTok Ads run through TikTok Ads Manager and appear natively in users' feeds as they scroll. Like other platforms, you choose an objective (awareness, traffic, leads, sales), set targeting and budget, and TikTok's algorithm optimises delivery.
What makes TikTok distinctive is how much the algorithm and creative drive results. TikTok's feed is content-first, so a genuinely engaging ad can be pushed to a huge audience cheaply, while a weak one dies quickly regardless of budget. The platform is built to surface content people enjoy, so ads that feel like native TikToks (rather than interruptive adverts) perform far better.
This means TikTok rewards volume and testing of creative more than fine bid-tuning: the businesses that win are usually the ones producing lots of authentic, native-feeling content and letting the algorithm find the winners. Creative is the lever, more than targeting or bidding.
What Are the Main TikTok Ad Formats?
TikTok offers several formats, most built around full-screen vertical video:
- In-Feed Ads — appear in the main "For You" feed as users scroll. The core format for most businesses; they look and feel like organic TikToks.
- Spark Ads — boost real organic posts (yours or creators'), keeping authentic engagement and social proof. Often the best performers.
- TopView and Brand Takeover — premium, high-visibility placements shown on app open. Expensive, for big awareness pushes.
- Branded Hashtag Challenges and Effects — encourage user participation; strong for viral brand campaigns with bigger budgets.
For most UK businesses, In-Feed Ads and Spark Ads are where to start, they are cost-effective, native and scalable. Spark Ads in particular let you amplify content that is already resonating, which is a reliable way to get more from what works.
How Do You Target the Right Audience on TikTok?
TikTok targeting options include:
- Demographics — age, gender, location and language.
- Interests and behaviours — based on the content people engage with.
- Custom audiences — retarget site visitors, video viewers and customer lists.
- Lookalikes — reach people similar to your best customers.
However, a key TikTok principle is that the algorithm is very good at finding the right audience if you feed it strong creative and clear conversion signals. Over-narrow targeting can actually hurt, because it limits the algorithm's ability to optimise. Many successful TikTok advertisers use broad targeting plus excellent creative, and let the system find who responds.
So on TikTok, targeting matters less than on LinkedIn or Google, and creative matters more. Give the algorithm room and great content, and it will typically find your buyers. Retargeting warm audiences (site visitors, engagers) remains valuable for driving conversions.
How Much Do TikTok Ads Cost?
TikTok is generally one of the more cost-effective platforms for reach and engagement. Typical UK costs:
- Cost per thousand impressions (CPM): often £3–£10, cheaper than most platforms for awareness.
- Cost per click (CPC): roughly £0.20–£1.00.
- Cost per result: varies widely with creative and offer.
TikTok Ads Manager has a minimum spend to run campaigns, and a realistic starting budget is around £500–£1,500 a month to gather enough data and test creative. Because creative is so decisive, budget for making several pieces of content, not just running one ad, TikTok success comes from testing and iterating.
As with any channel, the number that matters is cost per lead or sale against customer value, not CPM. TikTok's low reach costs make it powerful for building awareness and demand cheaply, provided your creative earns attention. Judge it on results and give the creative room to work.
What Makes TikTok Creative Convert?
On TikTok, creative is everything, so getting it right is the whole game:
- Look native — make ads that feel like organic TikToks, not polished commercials. Authentic beats slick.
- Hook in the first 1–2 seconds — TikTok is fast; grab attention instantly or lose it.
- Use trends, sounds and formats that are working on the platform right now.
- Show, do not tell — demonstrate the product, the transformation, the moment.
- Feature real people and creators — user-style content and creator partnerships build trust and perform strongly (Spark Ads shine here).
- Keep it short, punchy and clear with an obvious next step.
The brands winning on TikTok are rarely the ones with the biggest budgets, they are the ones making the most genuinely engaging, native content and testing relentlessly. If you can create (or commission) authentic short video consistently, TikTok can deliver reach and sales that are hard to get anywhere else.
