TikTok ads in 2026
It’s one of the most common questions we get as a TikTok marketing agency: are TikTok ads actually worth the investment? The honest answer is, it depends. But it depends in specific, predictable ways we can quantify.
This guide gives you the unvarnished picture of what TikTok advertising can deliver in 2026, where it works, where it doesn’t, and how to know in advance whether it’s the right channel for your brand.
The Short Answer
TikTok ads are worth it for brands willing to invest in platform-native creative and with a product or service that resonates with TikTok’s audience. They’re not worth it for brands that plan to repurpose TV ads or Instagram content without adapting for the platform.
The platform itself is not the variable that determines success. The creative is.
What the Numbers Actually Say
Here are data points from our own client campaigns that give a realistic picture of what TikTok advertising can achieve:
| Campaign / Metric | Result |
|---|---|
| App installs (CarCloud) | 100,000+ at 60p CPI — beating all other digital channels by 200%+ |
| TikTok Shop GMV | £7M+ for clients including The Ordinary and Vax |
| Tracked revenue from TikTok ads | £8M+ across our client portfolio |
| Average TikTok CPM (UK) | £3–£10 — typically lower than Meta equivalent |
| Over-55 CPA performance | Better than Facebook on one client — contrary to platform stereotype |
Where TikTok Ads Work Best
E-commerce with the right product
TikTok’s combination of organic discovery, creator affiliate content, and TikTok Shop ads creates a purchase journey that’s genuinely powerful for the right product categories.
Beauty, health, food, fashion, home, tech accessories – products that demonstrate well on video and sell at accessible price points consistently see strong results.
App install campaigns
TikTok’s algorithm is particularly effective at finding users likely to engage with specific apps. Our CarCloud campaign – 100,000+ installs at 60p CPI – is one example, but the pattern holds across multiple app install clients.
TikTok consistently competes favourably with Facebook and Google on CPI.
Brand awareness for 18–35 year olds
If your target audience is 18–35 and you’re building brand awareness, TikTok’s reach within that demographic is unmatched by any other single platform in the UK.
CPMs are generally lower than Meta and the immersive format delivers stronger attention metrics than standard display.
Brands with genuine TikTok content capability
The brands getting the best ROI from TikTok ads aren’t those with the biggest budgets — they’re the ones who understand the platform.
That means working with native creators, building platform knowledge in-house, or partnering with a specialist TikTok agency.
The creative is the primary variable.
Where TikTok Ads Don’t Work as Well
Highly considered B2B purchases
TikTok’s strength is discovery and impulse.
For enterprise software, professional services or complex B2B categories where the sales cycle is long and decisions involve multiple stakeholders, TikTok is unlikely to be your primary conversion channel.
Products that can’t be shown visually
TikTok is fundamentally a visual platform. Products and services difficult to demonstrate in a short video – abstract financial products, complex technical services – face a creative challenge that budget alone can’t overcome.
Brands unwilling to adapt their creative
This is the most common reason TikTok ads underperform.
Brands that repurpose existing TV ads, Instagram graphics or corporate video content without adapting for TikTok consistently see worse results than brands that invest in platform-native creative.
The creative is the targeting. On TikTok, the right content finds the right audience. The wrong content – however well-targeted – fails regardless of budget.
What Does a Proper Test Cost?
A meaningful TikTok ads test requires:
- A minimum of 60–90 days to get statistically useful data
- At least 3–5 creative variations (not one video and done)
- A daily budget of at least £50–£100 to drive enough impressions for meaningful learning
- Platform-native creative —-which may require creator fees, production costs, or agency support
Total minimum investment for a credible TikTok ads test: £5,000–£15,000 depending on your creative approach.
This is significantly lower than an equivalent test on Meta or Google, and the data you generate informs your strategy well beyond this initial test.
How to Know If TikTok Ads Are Right for Your Brand
- Is your target audience 18–45? A significant portion of them are on TikTok.
- Can your product or service be demonstrated effectively in 15–60 seconds? If yes, TikTok’s format suits you.
- Are you willing to create content that looks native to TikTok – not polished TV ads?
- Is your product in an accessible price range for considered-but-not-complex purchases?
- Can you measure success clearly – installs, purchases, form submissions?
If you answered yes to most of these, TikTok ads are worth testing. I
f you answered no to most, the channel may not be the right fit right now.
TikTok Ads vs Meta: How Does the ROI Compare?
If you’re weighing TikTok against your existing Meta spend, we’ve written a detailed breakdown in our TikTok Ads vs Meta Ads guide.
The short version: for younger audiences and e-commerce, TikTok often wins on CPM and ROAS. For broader demographics and retargeting, Meta is still stronger. Most brands should be running both.
The Competitive Argument for Acting Now
Beyond whether TikTok ads work, there’s a strategic timing argument worth considering.
TikTok’s advertising ecosystem is still less crowded than Meta’s, which means CPMs are lower and organic reach is still meaningful alongside paid activity.
The brands achieving the strongest results on TikTok – £8M+ in tracked revenue across our portfolio – started early enough to learn the platform before it became saturated.
Our Honest Assessment
TikTok ads are genuinely worth it for the right brands, with the right creative, and with realistic expectations.
The brands that fail on TikTok treat it as a cheaper version of Meta.
The brands that succeed treat it as a distinct platform with its own content culture.
