OTT (Over-The-Top) is bought on CPM only, averaging $33.60. YouTube Ads is bought on CPM only, averaging $8.40. 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 advertising on YouTube - skippable and non-skippable
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
OTT (Hulu, Peacock, Roku, Samsung TV+, etc.) is bought exclusively on CPM with 15- and 30-second video creative. Rates run $25–40 CPM — the highest of any digital channel — because inventory is finite premium video and the ROAS story is measured against linear TV, not against Facebook.
15s or 30s video, 1920×1080 (16:9), broadcast-quality mastering. No skippable formats. Most platforms require closed captions and mezzanine-file delivery through demand-side platforms.
OTT has a real budget floor: most DSPs require $5K–10K/month minimum, and to reach reliable frequency in a metro DMA you need $15K+/month per platform.
YouTube ads run through Google Ads on CPM (for TrueView and Bumper) or CPV (cost per view — you pay only when viewer watches 30s or engages). CPM averages $6–10; TrueView effective CPV is $0.05–0.15. Non-skippable pre-roll runs $15–25 CPM.
6s bumpers (non-skippable), 15/30s non-skippable, and TrueView (skippable after 5s, but you're only charged if viewer engages). 16:9 1920×1080; vertical 9:16 for Shorts inventory. Companion banners boost CTR.
$50–100/day covers TrueView on a defined-topic audience. Bumper campaigns can start at $30/day. YouTube's audience-based targeting means small budgets are viable for niche verticals.
