Advertising in Ireland

Ireland is a small but disproportionately strategic European ad market — CPMs run roughly 5% above US baselines, but the country's outsized role as the European HQ for Google, Meta, TikTok, LinkedIn, and most major tech platforms makes it relevant beyond its population (~5.2M). Most platforms' EU-wide commercial decisions are made in Dublin, and EU GDPR enforcement against US tech companies routes through the Irish DPC (Data Protection Commission), which has been historically criticized as slow but is now more active. Domestic ad spend is dominated by retail, financial services, telecom, and a notably high concentration of B2B SaaS due to Dublin's tech employer base. English-language creative is standard; Irish (Gaeilge) creative is rarely used outside specific cultural campaigns.

Under the hood

The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.

OTT (Over-The-Top)
How it bills

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.

Creative at a glance

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.

Min. spend for signal

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.

Pre-Roll Video
How it bills

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.

Creative at a glance

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.

Min. spend for signal

$3K–5K/month for standalone pre-roll; often bundled with programmatic display or OTT in a single video-inclusive DSP buy.

Advertising in Ireland: FAQs

The Irish DPC is the lead supervisory authority for Google, Meta, TikTok, LinkedIn, Apple, and most other major US tech platforms operating in the EU. Its rulings shape what those platforms can offer to advertisers across the entire EU — recent decisions have constrained Meta's behavioral advertising approach, for example. For media buyers, watching DPC activity is effectively watching the leading edge of EU adtech regulation.

Yes — Dublin's tech employer concentration (Google, Meta, LinkedIn itself, Stripe, Salesforce, AWS, plus a large indigenous SaaS base) makes LinkedIn unusually deep for B2B targeting relative to the country's size. CPMs typically run \u20ac35-\u20ac75 for tightly-targeted senior-tech audiences. International B2B brands often run Ireland-specific campaigns to reach EU regional decision-makers based in Dublin.

Slightly lower on average — Irish CPMs run roughly 10-15% below UK equivalents on Meta and Google for broad consumer targeting. The gap narrows for premium B2B LinkedIn inventory, where Dublin's tech concentration drives competitive pricing. EUR/GBP exchange shifts make the apparent gap move quarter to quarter, so denominate budgets and benchmarks carefully when comparing.
