How to Advertise on LinkedIn: An Irish SME Guide

LinkedIn Ads is paid advertising that finds people by the job they do, rather than by what they watch or scroll past. According to LinkedIn, the platform helps businesses reach professional audiences, promote products and services and generate leads through targeted campaigns. The shortest realistic path is one campaign in Campaign Manager, worked through in order: objective, audience, format, budget, creative and measurement.

How to advertise your business on LinkedIn#

You advertise on LinkedIn by building one campaign in Campaign Manager and working through six settings in order. LinkedIn describes that path as choosing an objective, audience targeting, ad format, budget and schedule, creative, and measurement. Imagine Brendan, who runs a small software company in Kilkenny selling compliance tools to HR teams.

1. Open Campaign Manager. LinkedIn Help describes Campaign Manager as the tool for creating and managing ad accounts and advertising campaigns. Set the currency to euro, add a payment method and give the account a clear name.
2. Choose one objective. Leads, website visits and awareness are three different jobs. Pick the one that matches what the business needs next, and never mix two in a single campaign.
3. Build the audience in plain words. Job title means the words on someone’s profile, such as HR manager or operations director. Seniority means how far up the person sits, from entry level to owner. Company size means the number of employees. Industry means the sector, such as software, manufacturing or healthcare. In a market the size of Ireland, two or three filters are usually plenty.
4. Pick one format. A single image ad or a short video ad is enough for a first campaign, and the section below explains where the other formats fit.
5. Set the budget and schedule. Choose daily, lifetime or both, and set the schedule for the hours when the sales team can answer enquiries.
6. Load the creative. Use one clear image or a short video, a headline that names the outcome, and copy that explains the offer in a few short lines.
7. Set up measurement before spending. Turn on conversion tracking (Recording which ad clicks turn into enquiries or sales.) so a click can be tied to an enquiry or a booked call.

LinkedIn works as a B2B channel because members describe their work on their own profile, and this guide to building a go-to-market strategy shows how a channel choice like that fits the rest of the plan. For contrast, TikTok advertising buys broad consumer reach, while LinkedIn narrows the audience to a chosen professional group. The most common mistake is running three audiences and three messages at once, which leaves nothing to learn from.

Tip: Build the first audience from the job titles on the profiles of the five best existing customers, then widen it only if the audience is too small for the budget.

How much do LinkedIn ads cost in Ireland?#

There is no fixed price list, because LinkedIn sells ad space through an auction. LinkedIn Help says ad cost is decided by an online auction system and by the campaign or ad set’s optimisation goal and bidding strategy. In practice, the price of a click or a lead depends on who else is bidding for the same audience at the same moment.

Budget options come next. LinkedIn Help lists three choices, daily, lifetime or daily plus lifetime, and default daily budget recommendations are available only in US dollars and euro. One condition catches people out. Where a campaign total budget is set, LinkedIn Help states that the campaign needs an unspent budget of €100 to launch a new ad set.

Irish buyers ask about two numbers most often: cost per click (What you pay each time someone clicks your ad.) and cost per lead (What you pay on average for one enquiry.). LinkedIn publishes neither as an official rate, so the table below gives wide planning ranges instead.

Note: A campaign with a total budget will not release a new ad set unless €100 of that budget is still unspent, so build every ad set on day one.

The ranges are wide on purpose. For Brendan, the useful question is not the average price of a click, but whether a click on an HR director is worth more than a cheaper click on a general HR audience.

What affects LinkedIn cost per click and cost per lead?#

Four things move the price most: the size of the audience, the competition in the sector, the objective and bidding strategy chosen, and how well the ad matches the offer.

Audience size is the first lever. A wide audience usually costs less per click than a narrow list of senior decision makers, because fewer advertisers chase that broad group. Sector matters as well, because software, finance, recruitment and professional services draw heavy advertising in Ireland.

The objective changes the number too. A campaign judged on clicks is priced differently from one judged on enquiries, and the second usually costs more for each action. The bidding strategy then decides how hard the campaign pushes for volume.

The ad itself matters more than most people expect. A clear offer and a short headline produce more enquiries from the same spend, and a three-field form brings more leads at a lower cost each, though those leads are weaker. Brendan’s plan sits inside the ranges above, and he compares every lead against the value of one software licence.

Which LinkedIn ad format fits the goal?#

Match the format to the goal rather than to fashion. Single image and video ads, known on LinkedIn as Sponsored Content, work for attention and website visits, lead generation forms (Short built-in forms that collect details without a website visit.) work for enquiries, Message Ads suit a short named list, and retargeting (Showing ads again to people who already visited your site.) brings back visitors who already know the business.

Brendan starts with single image ads and one lead generation form, and he leaves retargeting until the website has enough visitors each month. LinkedIn is one channel rather than the whole plan, and a paid ads plan that runs search and social together usually carries the load better than one channel alone.

A sensible starter budget for Irish SMEs#

A sensible first month is one campaign, two audiences at most and €1,000 to €1,500 of ad spend, with the build work paid for once.

The €100 rule shapes how the campaign is built. If Brendan sets a total budget of €1,500 for the month, the campaign needs €100 of that budget still unspent before any new ad set can launch. He therefore creates both ad sets on day one, while nothing has been spent, and leaves them alone afterwards.

Typical Irish market estimate, October 2026, excluding VAT.

What moves the total most is the creative and the landing page, not the ad spend itself. Those two items can be reused in later campaigns, so month two usually carries only the ad spend and the reporting.

Watch out: Do not judge the campaign after a weekend. Give it a fortnight of steady spend, then compare the leads with the value of one customer before pausing anything.

How Baikou’s team runs lead-form ads in practice#

Baikou’s team runs this kind of lead-form advertising on Facebook for a business selling in several countries. Each country gets its own creatives, its own offer and its own enquiry form, and an SMS check filters out junk enquiries before anything reaches the sales team.

Automations then move every enquiry into the CRM, where an AI assistant with a knowledge base about the company and its offers drafts the follow-ups, and a person checks them. A salesperson steps in once the lead is qualified and has started replying. The same pipeline works with LinkedIn lead generation forms.

Putting LinkedIn Ads to work inside an Irish business#

Ads bring the enquiry, but the systems behind them decide whether it becomes revenue. The practical next step is to fix one offer, one audience and one measurement before any budget is committed. From there, run the campaign as a monthly process rather than a one-off test.

Every form entry is personal data. The business needs a lawful reason to hold it, a record of consent where consent is that reason, and a way to delete it on request. In Ireland, the Data Protection Commission handles complaints about how personal data is used.

For Brendan, every enquiry should reach his sales lead the same working day and live in a CRM (Software that holds customer details, calls and sales notes.), not a shared inbox. Because many business-to-business sales close on a call or a signed order, add those offline wins back into the report by hand. Train the sales team on what a good lead looks like, then review each month which campaigns produced real conversations.

Off-the-shelf tools handle simple forms well but struggle with long sales cycles, offline conversions and consent records that must follow how the business actually sells. Where nobody in the team can own the campaign, outside set-up help is usually cheaper than a stalled trial.
