TikTok ads reach over 1 billion users, and CPMs are still significantly lower than Meta and Google. Early movers on TikTok Ads are seeing some of the best returns in digital advertising right now.
Getting Started with TikTok Ads
Stop treating TikTok Ads Manager like a lesser version of Meta. It is not. Right now, it is one of the most cost-efficient paid channels available to UK advertisers, and most of your competitors are either ignoring it or running it badly. That gap will not last. The brands building TikTok ad capability today are locking in CPMs of £3 to £8 at a time when Meta is routinely charging £10 to £18 for the same UK audiences. When the market catches up, and it will, those early movers will have the data, the creative muscle, and the algorithm history to compete. Everyone else will be paying a premium to enter a crowded auction.
TikTok Ads Manager is the platform's self-serve advertising tool, allowing businesses to create, manage, and optimise paid campaigns across TikTok and its partner apps. Newer than Meta or Google's ad platforms, TikTok Ads Manager has matured rapidly and now offers sophisticated targeting, creative tools, and measurement capabilities that hold up against either platform in most campaign types.
What makes TikTok particularly compelling right now is its audience composition and engagement rates. The platform is no longer exclusively a Gen Z playground. Over 40% of TikTok's UK user base is aged 25 or above, and the average user spends roughly 95 minutes per day on the app. According to Ofcom's 2023 Online Nation report, TikTok is now used by 29% of UK adults aged 16 to 64, with time-on-app figures that outpace every other social platform measured. That depth of attention, combined with a relatively uncrowded advertising auction, creates an opportunity that sharp marketers are capitalising on before budgets inflate and CPMs rise to match the other major platforms.
To put this in concrete terms: a UK e-commerce brand running a product launch on Meta might pay £12 to £15 CPM during a competitive period. The same campaign on TikTok could achieve £4 to £6 CPM, delivering two to three times the impressions for the same spend. For awareness campaigns in particular, that difference compounds dramatically over a campaign flight.
The account setup process mirrors other platforms: create a TikTok Ads account, install the TikTok Pixel on your website for conversion tracking, set up your billing, and configure your account settings. The pixel is non-negotiable. Without it, you cannot track conversions, build retargeting audiences, or optimise for business outcomes. Do not spend a single pound on TikTok ads before it is installed and verified.
When installing the pixel, you have two options: manual code installation (paste the pixel script into the <head> tag of your site) or partner integrations (Shopify, WooCommerce, and most major CMS platforms have native TikTok Pixel connectors that handle installation without touching code). For client websites, the partner integration route is almost always faster and less error-prone. Always verify the pixel is firing correctly using TikTok's Pixel Helper Chrome extension before launching any paid activity.
Enable Advanced Matching when setting up your pixel. This feature sends hashed customer data, email addresses and phone numbers, alongside pixel events, helping TikTok's algorithm match conversions more accurately, particularly in a post-iOS 14 environment where browser-based tracking is less reliable. Brands who enable Advanced Matching typically see a 10 to 20% improvement in reported conversion attribution.
TikTok's campaign structure follows the familiar hierarchy: Campaign (objective), Ad Group (targeting, budget, schedule, placement), and Ad (creative and copy). Available objectives include Awareness (reach), Consideration (traffic, video views, community interaction), and Conversion (website conversions, lead generation).
Choosing the right objective matters more than most beginners realise. If you select a Traffic objective, TikTok's algorithm optimises for clicks. It finds people most likely to tap your link. If you select Conversions, it optimises for purchases or form completions, which requires the pixel and ideally at least 50 conversion events per week to exit the learning phase. For new accounts with limited data, start with Traffic to generate pixel events before switching to a Conversion objective once you have sufficient data for the algorithm to work with.
At Byter, we have seen TikTok Ads deliver exceptional results for hospitality clients, particularly for reaching younger demographics. The CPMs are typically 30 to 50% lower than Meta, meaning your budget goes further. The creative requirements are different though. Ads must feel native to TikTok to perform. That is the trade-off, and it is one worth making.
Understanding TikTok's Campaign Structure in Depth
Understanding where each decision lives within the three-tier structure helps you test more efficiently and diagnose performance issues faster.
Campaign level is where you set your objective and campaign-level budget cap. Keep this broad. One campaign per objective is usually sufficient when starting out. Resist the urge to create multiple campaigns for the same objective. It splits your budget and prevents the algorithm from learning efficiently.
Ad Group level is where the bulk of your targeting decisions happen. Here you define your audience (interests, behaviours, demographics, or custom audiences), your placements (TikTok only, or including partner apps like Pangle), your budget and schedule, and your bidding strategy. A common mistake is over-targeting at the ad group level. TikTok's algorithm is powerful, and overly narrow audiences restrict its ability to find the right users. Aim for audience sizes of at least 500,000 for most campaigns.
For a practical example: if you are advertising a fitness supplement brand, rather than stacking five interest categories simultaneously (fitness + nutrition + health + sport + wellness), try separate ad groups with single broad interests. This lets the algorithm demonstrate which interest pool performs best and gives you actionable data rather than blended, uninterpretable results.
Ad level is where you upload your creative, write your ad copy, choose your call-to-action button, and select your destination URL. TikTok recommends testing a minimum of three to five creatives per ad group so the algorithm has options to serve. Treat each creative as a hypothesis: creative A tests a testimonial hook, creative B tests a product demo, creative C tests a problem-agitate-solve structure. The algorithm will allocate spend towards whichever performs best, but you retain the learning about which creative approach resonates with your audience.

TikTok Ads Best Practices
The golden rule of TikTok advertising is: Don't make ads, make TikToks. Ads that look and feel like organic TikTok content consistently outperform polished, traditional advertisements. Use vertical video, trending sounds, native text overlays, and a casual, authentic presentation style.
This distinction is critical and often where brands with big production budgets go wrong. A slickly produced 30-second commercial with a brand logo in every frame, glossy product shots, and a voiceover will be scrolled past in an instant. A shaky iPhone video of a real person demonstrating your product with a trending audio track will stop the scroll and drive results. TikTok's own data shows that ads featuring real people speaking directly to camera achieve 30% higher engagement than those that do not.
A useful real-world illustration: a Byter client in the food and beverage sector invested in a professionally filmed ad with studio lighting, polished graphics, and a branded end card. It generated a 0.4% CTR and poor view-through rates. We then created a 22-second iPhone video of a staff member doing a product taste test in the kitchen, with a trending sound and on-screen captions. That creative delivered a 2.1% CTR and a 68% average watch time. Same audience. Same budget. Fundamentally different creative philosophy.
The Hook is Everything. TikTok's algorithm measures watch time ruthlessly. If viewers drop off in the first second, the ad is deprioritised and your CPMs rise. Hooks that work well include: starting mid-action (don't waste time with intros), opening with a bold text statement on screen, posing a provocative question, or beginning with a surprising visual. Think about what would stop you scrolling, then lead with that.
Proven hook formulas for TikTok ads include:
The bold claim: "This changed how we run our business completely."
The direct call-out: "If you live in Manchester and love craft coffee, watch this."
The pattern interrupt: Begin mid-demonstration, show the finished result before explaining how you got there.
The social proof opener: "Over 10,000 people have tried this, here's why they came back."
This structure maps directly to the Hook-Hold-Convert Method we use at Byter across all content and paid creative. Hook in the first three seconds, hold attention through to at least 15 seconds with genuine value or demonstration, then convert with a single clear CTA. On TikTok, the hold phase is where most brands lose. They nail a strong opening and then drift into brand messaging that kills momentum. Keep the value delivery tight and specific all the way to the CTA.
Keep ads short. 15 to 30 seconds is the sweet spot. Hook in the first second. Use real people rather than stock footage. Show the product or experience in action. Always include captions, as many users browse with sound off. TikTok's auto-caption tool handles this natively within Ads Manager.
Common Mistakes to Avoid:
Repurposing landscape or square videos from other platforms. Always shoot vertically in 9:16
Running only one creative per ad group and wondering why performance stalls
Setting audience interests too narrowly and restricting the algorithm's ability to find buyers
Launching a Conversion campaign without enough pixel data (fewer than 50 events per week)
Ignoring the learning phase. Allow campaigns at least 7 to 10 days before drawing conclusions or making significant changes
Adding a watermark from another platform (particularly the Instagram Reels logo). TikTok's algorithm actively suppresses content bearing competitor watermarks
Using a voiceover in the style of a traditional radio or TV commercial. This signals "ad" immediately and drives scroll-aways
Byter Tip
Byter Insider: We ran a TikTok Ads campaign for a fast-casual restaurant group in Shoreditch launching a new menu. Rather than producing new content from scratch, we applied our Content Flywheel approach, pulling the three best-performing organic TikToks from their account (a chef prep video, a customer reaction clip, and a trending sound duet) and pushing them as Spark Ads with a £30 per day budget per creative. Within the first two weeks, CPM came in at £4.20 against a Meta benchmark of £13.80 for the same audience. The chef prep video hit a 34% hook rate and 61% average watch time, well above platform benchmarks. By week four, 22% of their new reservation enquiries were attributable to TikTok, tracked via UTM parameters through their booking platform. The entire creative cost was zero. The budget went entirely on distribution.
TikTok's Unique Targeting Options
Beyond standard demographic and interest targeting, TikTok offers several targeting features worth understanding early:
Hashtag targeting allows you to reach users who have recently engaged with specific hashtags. This is highly useful for niche communities and interest groups. A gym equipment brand could target users who have engaged with #homegym or #fitcheck content in the past 30 days, reaching an audience that has demonstrated active interest rather than just fitting a demographic profile.
Custom Audiences work similarly to Meta's. Upload a customer email list, target website visitors via the pixel, or build lookalike audiences from your best customers. Lookalikes on TikTok tend to perform particularly well once you have at least 1,000 matched users in your seed audience. For best results, build your lookalike from your highest-value customers rather than all customers. The algorithm replicates the signal you give it.
Smart Audience is TikTok's automated targeting mode, where you give the algorithm minimal constraints and let it find users most likely to complete your objective. For newer accounts, this can outperform manually constructed audiences because it removes human assumptions from the equation. Think of it as equivalent to Meta's Advantage+ audience targeting: surrendering control in exchange for algorithmic efficiency.
Video Interaction Audiences are a particularly underused feature. You can retarget users who have watched a percentage of one of your existing TikTok videos. This allows you to build a warm mid-funnel audience from organic content viewers and serve them a conversion-focused ad. It is a highly cost-effective retargeting mechanic that maps directly to the 3-Layer Targeting Model: cold audiences at the awareness stage, video viewers as your warm layer, and website visitors or add-to-carts as your hot layer ready for conversion messaging. Most brands running TikTok Ads are only working the cold layer. The warm retargeting opportunity is largely untapped and consistently delivers the lowest CPAs we see on the platform.

Budgeting and Bidding on TikTok Ads
TikTok Ads Manager uses an auction-based system with three primary bidding strategies:
Cost Cap: you set the maximum cost per result you are willing to pay, and TikTok's algorithm attempts to stay within that threshold while maximising results. Good for campaigns with strict cost-per-acquisition targets.
Bid Cap: a more aggressive cap on what TikTok bids in each auction. This can limit delivery if set too low, but gives you tight cost control.
Lowest Cost (no bid cap): TikTok spends your budget to get as many results as possible at the lowest available cost. Best for new campaigns where you do not yet know your benchmark CPA.
For testing, start with Lowest Cost. Once you have 20 to 30 conversion events, you will have a realistic CPA to use as your Cost Cap target.
Minimum daily budgets are £20 at the ad group level. Start at £20 to £50 per day per ad group during testing, then scale winning combinations. A common scaling mistake is doubling budget overnight. Increases of more than 20 to 30% at a time can disrupt the algorithm's learning and spike your CPA. Scale gradually and monitor the first 48 hours after any budget change carefully.

Scaling What Works: The Creative Iteration Loop
Once you have campaigns running and initial data coming in, the real work begins. TikTok creative fatigue sets in faster than on other platforms. The feed is content-first and users consume enormous volumes of video daily, meaning the same creative can exhaust its audience in one to two weeks, particularly in smaller UK markets.
Establish a regular creative iteration cycle. Every one to two weeks, review your ad-level performance data. Pull the metrics that matter: hook rate (the percentage of viewers who watch past the first three seconds), average watch time, CTR, and conversion rate. Any creative missing two or more of those benchmarks is a candidate for replacement.
When you find a winner, iterate rather than reinvent. Swap the hook while keeping the body of the video the same. Try a different music track. Test the same script with a different presenter. You are looking for which variable drives the performance, not just hoping something new works.
