Programmatic Display averages $0.66 CPC and $3.30 CPM. Pre-Roll Video is bought on CPM only, averaging $18.00. 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.
Automated display ad buying across multiple exchanges
Video ads that play before online content
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
Programmatic display buys the same display inventory as GDN plus long-tail supply-side sources (AppNexus, Xandr, Magnite) through a demand-side platform. Every impression is a real-time auction. CPMs are the lowest of any channel ($2–5) but so is attention.
All standard IAB banner sizes: 300×250, 728×90, 160×600, 320×50 mobile, plus HTML5 rich media for higher-tier placements. Video pre-roll in the same DSP: 15s/30s at 1080p.
$3K–5K/month is the practical DSP minimum. Retargeting on programmatic is where small budgets get outsized ROI.
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.
