Pre-Roll Video is bought on CPM only, averaging $18.00. TikTok Ads is bought on CPM only, averaging $10.80. Analysis for United Kingdom in 2026.
The UK is Europe's largest digital ad market and one of the most mature globally, with roughly three-quarters of total media spend now flowing through digital channels. Google and Meta together capture more than 60% of that, but the UK has unusually strong adoption of programmatic display, connected TV (ITVX, Channel 4, Sky), and Amazon Ads relative to mainland Europe. CPMs trend 15-25% above the US in several premium categories — partly auction density, partly currency. The UK GDPR (post-Brexit) plus the ICO's increasingly assertive guidance on cookies and consent make first-party data strategy a real competitive advantage here, not an afterthought.
Video ads that play before online content
Short-form video advertising on TikTok
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
Pre-roll (the video ad before online video content, non-YouTube) is CPM-priced at $12–20, sold through DSPs against a video inventory pool separate from social. Skippable and non-skippable formats coexist; non-skippable commands a 20–30% CPM premium.
15s (most common), 6s bumper, or 30s. 1920×1080 16:9, 24 or 30fps, H.264. Captions and audio-off usability increasingly required as autoplay-muted becomes default.
$3K–5K/month for standalone pre-roll; often bundled with programmatic display or OTT in a single video-inclusive DSP buy.
TikTok Ads runs on CPM ($8–12 typical, higher for premium placements like TopView). CPC is available but the platform's optimization heavily favors CPM-bid campaigns. Auction density is lower than Meta but growing quickly; creative quality dominates.
9:16 vertical video (1080×1920), 9-60s (best performance 15-30s), native-feeling — polished ads underperform UGC-style creative here by 2-3x. Sound-on is standard. Captions optional but boost completion.
$500/day ($15K/month) is the practical floor for the Traffic and Conversion objectives to exit learning phase in a reasonable window. Smaller budgets work for Awareness and Video View goals.
