The short answer
Ireland is a compact market with a disproportionately large agency sector, because Dublin hosts the European operations of many global brands alongside a strong indigenous SME base. Most buyers end up choosing between three types: a large integrated group, an award-driven independent creative shop, or a specialist performance, web or PR firm. Digital now takes the majority of working budget, so ask any generalist how much of your money will actually be spent in channels their own team runs.
Market size and shape
Digital advertising spend in Ireland reached €1.06 billion in 2024, up 11% year on year, according to IAB Ireland's adspend study with PwC. Within that, digital display grew 15% to €589 million in 2023, with video a primary driver, as reported by IAB Ireland and RTÉ. Core forecast the total Republic of Ireland advertising market at €1.53 billion for 2024, and reported digital at roughly 64% of overall advertising revenue.
For buyers, two practical consequences follow. First, search and social capability is deep and competitively priced. Second, senior brand strategy and effectiveness expertise concentrates in a smaller number of larger groups and established independents, so it costs more and books out further ahead.
Rules that shape the work
- **Advertising content.** The Advertising Standards Authority for Ireland administers the code and publishes complaint data. Its 2023 reporting showed influencer-related advertising accounting for around a fifth of complaints, so any creator programme needs documented disclosure standards.
- **Email, SMS and calls.** Electronic direct marketing is governed by GDPR together with the ePrivacy Regulations 2011 (SI 336 of 2011). The Data Protection Commission's direct marketing guidance sets out when consent is required before contacting individuals.
- **Data handling.** Because so many multinationals base European data operations in Ireland, agencies here are usually fluent in consent management and measurement under GDPR. Ask to see how they configure consent mode and server-side tagging before you accept any attribution claim.
What to ask on a shortlist call
1. Who exactly will run this work day to day, and what else are they on? 2. Show me a comparable project: the brief, what you did, and what changed afterwards. 3. Where did the numbers in that case study come from, and can the client confirm them? 4. How do you handle consent and measurement under GDPR and the ePrivacy Regulations? 5. If we stop working together in six months, what do we keep?
Weak evidence to watch for
Effectiveness awards are useful in Ireland because entries are documented, but a shortlisting is not a win and a win is not proof your category will behave the same way. Treat unlinked award claims, ranking claims with no query or date, and return figures with no baseline as unverified until you have seen the account.
How we assess agencies
Every Irish listing on this site is built from the agency's own published material and named press, industry or award bodies. We do not use directory ratings. Scoring runs on a published 100-point methodology, and demonstrated results and verified review quality stay at zero until we hold source-verified evidence.
