Top Online Advertising Agencies in Ireland (Updated August 2026)

The companies in this list are ordered alphabetically by name. That is the only ordering applied, so a company's position implies no ranking, preference or assessment of quality.

Paid media is a daily job rather than a campaign. The bidding, budget and audience decisions taken between reports are what decide whether spend converts or evaporates. Most agencies here also make the creative and set up the conversion tracking underneath it. Starting budgets run from 275 to 4,500 euro, and the fee model matters as much as the figure, because a percentage of spend pays the agency more for spending more of your money.

Who owns the ad account when you leave?

  • Fee model, stated plainly. Flat retainer or percentage of spend. The second one pays the agency more when it spends more of your budget.
  • Account ownership. Your ad accounts and your data should be in your name. Agencies that resist this are creating a switching cost.
  • Depth over breadth. An agency spending daily in one platform beats one nominally covering six.
  • Review volume. Rare in this market, so where it exists, read it properly.
  • Whether a prize mechanic is involved. Prize-led campaigns convert well and carry rules most advertisers miss, so read up on running a competition or prize draw before the media is booked.

Before signing, ask who owns the ad account, the pixel and the historical data. Losing years of conversion history in an agency switch costs more than the retainer you were arguing about.

Matching agency size to your spend

Ireland's paid media agencies range from solo operators to teams of hundreds, and the difference in what you get is not just price. Match the agency's size to your budget and complexity rather than to its portfolio.

  • Contract length. Many agencies bind clients to three or six month terms. Ask what happens to your creative library and campaign history if you leave early.
  • Creative versus media split. Some agencies build ads and buy media themselves. Others outsource creative and only manage spend. Ask who actually produces what you will run.
  • Minimum spend thresholds. Budgets here start from 275 euro at one end and 4,500 euro at the other. Below an agency's usual threshold, expect a junior account handler rather than senior attention.
  • Reporting cadence. A weekly dashboard versus a monthly call is a real difference in how fast you can catch a campaign going wrong.
  • Who owns the landing page. Paid performance is capped by it, and most agencies here will not touch it. The conversion and user research firms will.
  • Sector experience. An agency used to hospitality or ecommerce brings platform-specific playbooks that general experience does not match.

Where paid media stops and another discipline starts

An online advertising agency plans, builds and runs paid campaigns across platforms such as Google, Meta, LinkedIn and programmatic display, then manages the daily bidding and budget decisions that decide whether spend is wasted or converted. Most also produce the ad creative, set up conversion tracking and report on cost per acquisition rather than clicks alone.

What usually sits outside this: organic search, PR, brand strategy and, in most cases, the landing page build itself, though a few agencies here fold that in.

Two neighbouring categories are worth checking before you brief. Once the plan spans more than digital channels, it belongs with the media agencies on this list. And paid social straddles both categories, so if creative and community matter as much as the buying, the social media agencies are the better brief.

Businesses typically bring this work in when a founder can no longer run campaigns alongside everything else, when monthly spend crosses a few thousand euro and mistakes get expensive, or when conversion tracking needs setting up properly for the first time. Below that point, a business often manages its own campaigns. Above it, an agency's platform experience starts paying for itself.

Retainer, percentage of spend, or one-off project fee

This list publishes no hourly rates, only starting project budgets, and they range from 275 euro to 4,500 euro. Most sit around 900 euro, which functions as the common entry point for an ongoing paid media retainer in Ireland.

The usual pricing models here are a flat monthly retainer, a percentage of ad spend, or a one-off project fee for a single campaign build. A percentage fee means the agency earns more as your spend grows, so ask for a cap before signing.

What moves the price: how many platforms you run on, whether creative production is included, how much conversion tracking needs building from scratch, and how often the agency reports. The 4,500 euro entry points here belong to agencies with review evidence and larger teams. The 275 to 900 euro range covers founder-led shops better suited to a smaller monthly budget.

  1. 1. 23 The Agency

    Best for creator-supported campaigns

    Location
    County Dublin, Ireland
    Team size
    1-10

    23 The Agency runs creator-led campaigns for beauty, fashion and lifestyle brands from County Dublin, with a team of under ten led by director Mark Rogers.

    What sets them apart

    The unusual part of the offer is talent management alongside campaign work: the agency represents online personalities as well as booking them for brands. That shortens the route to a creator, and it also puts the agency on both sides of a negotiation, which is worth asking about directly.

    Who they suit

    Services also cover PR and events. No starting budget or rate is published and there are no verified reviews on the listing. It suits a consumer brand whose plan is built around named creators rather than paid placements, and it is the wrong fit for search or programmatic work, neither of which the agency lists.

  2. 2. Acolad

    Best for advertising across multiple languages

    • Top awarded
    Location
    Dublin, Ireland
    Team size
    1001-5000
    Min project
    From €900

    Acolad is a language and content company founded in 1995, with 1,001 to 5,000 staff globally and a Dublin presence. It is the only entry on this list whose core service is translation and localisation rather than media buying.

    What sets them apart

    The relevance to advertising is campaign adaptation: getting ad copy to hold its tone and persuasive intent in another language, using a mix of human linguists and machine translation tooling. Sectors are government and administration, technology and e-commerce.

    Who they suit

    Projects start from 900 euro and the listing carries a top-awarded badge, with English and Chinese as the working languages shown. It suits a company already running campaigns that now needs them to work in several markets. It will not plan or buy your media, so it sits alongside an advertising agency rather than replacing one.

  3. 3. CJ Digital Marketing

    Best for founder-led work for SMEs

    Location
    Cork, Ireland
    Team size
    1-10
    Min project
    From €275

    CJ Digital Marketing is run by its founder, Charlie Johns, from Cork, with a team of under ten. The work is Google and Meta ads for local service businesses, retailers and trades, with SEO and web design alongside.

    What sets them apart

    Two things stand out on the listing. Projects start from 275 euro, the lowest entry point here by a wide margin, and the ongoing service is offered with a money-back guarantee, which almost no agency in this market does. Ask exactly what triggers it and over what period.

    Who they suit

    There are no verified reviews on the listing. It suits a small business that wants managed campaigns on a budget that would not open a conversation elsewhere. A founder- led shop this size means direct access and a hard ceiling on how much can run at once.

  4. 4. Hovi Digital Lab

    Best for AI-assisted lead generation

    • Top awarded
    Location
    Dublin, Ireland
    Rating
    4.8 (5 reviews)
    Team size
    51-200
    Min project
    From €4,500

    Hovi Digital Lab runs paid advertising from offices in Dublin, Dubai and Beirut with a team of 51 to 200. Campaign management leans on automation, with bidding and targeting adjusted continuously rather than reviewed on a weekly cycle.

    What sets them apart

    Clients are software, computer services and technology firms. The team works in English and Arabic, which matters for brands expanding into Middle Eastern markets.

    Who they suit

    Projects start from 4,500 euro, at the top of the range on this list, and the listing holds a top-awarded badge with 5 verified reviews at 4.8. It suits an organisation with enough monthly spend that automated bid management pays for itself. Five reviews is a small sample for a team this size, so ask for references at your budget level rather than their largest account.

  5. 5. iDigitalise.net☑️

    Best for campaigns run across several markets

    • Highly recommended
    • Top awarded
    Location
    Dublin, Ireland
    Rating
    4.9 (47 reviews)
    Team size
    51-200
    Min project
    From €900

    iDigitalise runs paid advertising and SEO from Dublin, with offices in Albania, the United Arab Emirates and the United States, and a team of 51 to 200.

    What sets them apart

    Its distinguishing feature on this list is review volume: 47 verified reviews at 4.9, more than every other agency across these directories combined. In a market where most listings carry no reviews at all, that is the strongest evidence available here, and it is worth reading rather than counting.

    Who they suit

    Projects start from 900 euro, which is low for the team size. Sectors are internet and technology, and the listing carries the directory's "Highly recommended" and "Top awarded" badges. It suits a business running campaigns in more than one market, though the 900 euro floor against a team that size means asking who will actually hold your account.

  6. 6. MarketingConsultant.ie

    Best for strategy-led paid search

    Location
    Dublin, Ireland
    Rating
    5.0 (1 review)
    Team size
    1-10
    Min project
    From €900

    MarketingConsultant.ie is a one-person consultancy in Stillorgan, Dublin, run by Ronan Hickey, who manages paid campaigns across Google, Bing, LinkedIn and social platforms directly rather than through an account team.

    What sets them apart

    The model is closer to a fractional marketing director than an agency. Strategy and an audit of existing activity come before any spend, so advertising is tied to a commercial goal rather than run as a standing line item. Clients are e-commerce and retail businesses.

    Who they suit

    Projects start from 900 euro. The listing shows 1 verified review at 5.0, which is not a sample worth drawing conclusions from. It suits a business that needs senior judgement and cannot justify a full-time marketing hire; single-operator consultancies carry an obvious continuity risk, so ask what happens during holidays and illness.

  7. 7. Riordan SEO

    Best for paid and organic search together

    Location
    Dublin, Ireland
    Team size
    1-10
    Min project
    From €4,500

    Riordan SEO is a search marketing agency working out of Dublin and Cork under its founder, Fintan Riordan, with a team of under ten. It runs paid search and organic search together rather than as separate engagements.

    What sets them apart

    That combination is the point of the offer: paid clicks cover the queries where organic rankings are absent, and the organic work gradually reduces what has to be paid for. Sectors are software, e-commerce and B2B services.

    Who they suit

    Projects start from 4,500 euro, the joint highest entry point on this list, and there are no verified reviews on the listing. It suits a business that already gets most of its leads from search and wants one team accountable for both halves of it. The price floor rules out smaller monthly budgets.

  8. 8. SPB Media Ltd - Hospitality Marketing Experts

    Best for hospitality advertising

    Location
    Dublin, Ireland
    Team size
    1-10

    SPB Media works only in hospitality: restaurants, food and beverage brands and events, from Dublin with a team of under ten. Services are brand positioning, TikTok advertising and social media management.

    What sets them apart

    The single-sector focus means the agency already knows what a quiet Tuesday looks like and what a booking costs to generate, which a generalist has to learn on your budget.

    Who they suit

    No website, starting budget or rate appears on the listing, and there are no verified reviews. It suits a restaurant or venue group whose advertising is mostly social and video. The narrow platform list is the constraint: if the plan needs Google search or programmatic display, this is not the agency for it, and the missing commercial detail means everything gets established on a call.

  9. 9. Stone & Vale

    Best for agency experience at lower cost

    Location
    Letterkenny, Ireland
    Team size
    1-10
    Min project
    From €900

    Stone & Vale is a remote-first team of under ten based in Letterkenny, selling paid advertising, SEO and growth marketing to businesses across Ireland.

    What sets them apart

    Having no office is the commercial argument: the overhead that funds a Dublin agency's account structure is not in the rate, so senior time lands on smaller budgets. Sectors are e-commerce, B2B services and retail.

    Who they suit

    Projects start from 900 euro and there are no verified reviews on the listing. It suits a business outside the main cities, or one in Dublin that does not want to pay city rates for campaign management. As with any team this size, ask about capacity: how many accounts run at once, and who covers yours when someone is away.

  10. 10. Together Digital

    Best for enterprise and Fortune 500 experience

    • Best Large Digital Agency (Irish Web Awards)
    Location
    County Dublin, Ireland
    Team size
    1-10

    Together Digital is a digital agency in Dublin 3 with a team of under ten, covering digital strategy, web design and marketing for corporate, financial services and consumer goods clients.

    What sets them apart

    The listing carries a Best Large Digital Agency award from the Irish Web Awards, which is a named award from a real programme rather than a self-description. There is a mismatch worth raising on a call: the award category says large, the listed team size says under ten.

    Who they suit

    No starting budget or rate is published, and there are no verified reviews on the listing. It suits a corporate or financial services brand that wants strategy, build and advertising from one supplier, and because no commercial detail is published the budget conversation happens on the first call.

Online advertising gets a business in front of people actively looking to buy, and a well run campaign can prove it with real numbers. What it doesn't do is make that customer buy a second time without paying for another click. Acquisition and repeat purchase are billed differently, and the second one is usually cheaper to earn than to buy. Brandfire designs and builds loyalty and rewards programmes for brands across Ireland, the work that reduces how much of that ad spend has to happen twice.

Frequently asked questions

How much does online advertising cost in Ireland?
Starting budgets here run from 300 to 5,000 euro, and that is the agency fee rather than the media spend. Most agencies charge either a flat retainer or a percentage of spend. Ask which model applies, because a percentage fee rewards the agency for spending more of your money.
Should the agency fee include media spend?
Usually not, and you should insist the two are separated on every invoice. Bundled billing makes it impossible to see what you paid the platform versus the agency. Ask for direct access to your own ad accounts so the data is yours.
How do I judge a paid media agency?
Ask for a named client whose account they lost and why. Agencies that answer honestly usually understand attribution well. Then ask which platform they spend most in monthly, because breadth across six platforms often means depth in none.
What review counts should I expect?
Very few. One agency here has 47 verified reviews, another has five, and the rest have none. That single 47-review profile is the strongest evidence in this entire set of Irish agency lists, and it is worth reading rather than skimming.
How quickly does online advertising show results?
Faster than most other channels, since paid campaigns can start driving traffic within days of launch. Drawing conclusions still takes longer. Give a new campaign two to four weeks and a reasonable share of the budget before judging cost per acquisition, since platforms need data to optimise delivery properly.
