LinkedIn Ads for B2B: When It Works, How the Targeting Works, and What It Costs

LinkedIn is worth its price when your buyer is identifiable by employer, role and seniority, and the deal is big enough to absorb an expensive click. For Critical Minds, a Dutch management consultancy, tightly matched targeting produced 8 per cent CTR at EUR 1.00 CPC. When the buyer is not identifiable that way, spend the money on search instead.

That is the whole decision, and most of what follows is about the two halves of it: how the targeting model actually works, and what the arithmetic has to look like before it is worth using.

When LinkedIn is the right channel

The case for LinkedIn is precision, and precision is the only thing it sells that the other large paid channels do not. You can address the finance directors at manufacturing companies with 200 to 1,000 employees in Belgium and the Netherlands, and nowhere else can do that in one campaign builder.

Precision costs money. A LinkedIn click is expensive relative to what the same click costs on search or on Meta, which is a directional claim any practitioner will confirm and which is doing all the work a made-up average would do. The consequence is a simple filter: the channel earns its place when the value of reaching exactly the right person exceeds the premium you pay to do it.

That filter rules LinkedIn out more often than the genre admits.

Skip it when the buyer is not identifiable by firmographics. If your customer is an SME owner, an independent developer, or anyone who treats LinkedIn as a place they keep a CV rather than a place they work, you are paying for targeting you cannot use.

Skip it when the deal is small. Work the chain: click cost, clicks per conversation, conversations per deal, deal value. If a deal cannot absorb the cost of the clicks it takes to find it, the channel is wrong and no creative fixes it.

Skip it when you cannot describe your ICP in LinkedIn's terms. The platform's advantage is that it will address a list of job functions at a list of companies. If you cannot write those two lists, a broader channel gives you the same result cheaper.

Skip it for Japan and Korea. LinkedIn is small in Japan and used for different purposes; see LinkedIn in Japan for the size question and advertising in Japan for what to buy instead.

The targeting model

This is the part worth learning properly, because it is the product.

Company attributes. Company name, industry, size band, growth rate, and uploaded lists of companies. This is the layer most European B2B campaigns should start from, because most European B2B ICPs are firmographic before they are anything else.

Member attributes. Job title, job function, seniority, years of experience, skills, degrees and fields of study, and group membership. Job title and job function behave differently and the difference matters: titles are what people write about themselves and vary wildly across languages and company cultures, while function is LinkedIn's own normalisation. In multilingual European campaigns, function plus seniority is usually more reliable than a title list.

Skills. Underused, and genuinely useful for technical audiences where the job title tells you nothing. A skill is self-declared, which is a weakness for seniority and a strength for capability.

Audience uploads. Contact lists and company lists, uploaded or pushed from a CRM. This is how account-based work happens on LinkedIn, and it is the subject of LinkedIn account based marketing in more detail than fits here.

Retargeting. Two sources. Website visitors, captured by the LinkedIn Insight Tag. And on-platform engagement: people who watched a video, opened a lead form, clicked an ad, visited the company page, or responded to an event. The second is the more interesting one for a European B2B advertiser, because it works without depending on cookie consent behaviour on your own site.

Exclusions. Exclude your own employees, your current customers and your recent converters. Almost nobody does this at launch and it quietly wastes a meaningful share of the budget.

Two constraints sit over all of it.

The first is the audience floor: LinkedIn will not run a campaign below 300 members. Layer aggressively enough and you will hit it, at which point you widen a facet, merge two markets, or accept that the segment belongs to sales rather than to media.

The second is that Audience Expansion and the LinkedIn Audience Network both widen delivery beyond the audience you defined. Which of them is on by default has varied by objective and format, so do not rely on remembering. Open the settings and decide deliberately. A campaign built on careful layering and then delivered through an expanded audience is a campaign you cannot read.

Formats, briefly

Single image, video, carousel, document and text or spotlight units cover almost everything. Lead Gen Forms pre-fill from profile data and sit on top of most of them.

One European constraint is worth stating because it invalidates whole plans: LinkedIn stopped serving Message Ads and Conversation Ads to members located in the EU, a privacy-driven change from 2022. If your plan involves Sponsored Messaging into Europe, check Campaign Manager before you build it.

Beyond that, do not take format performance rankings from articles, including this one. Which format wins depends on the offer and the audience, and it is cheap to test.

There is one format decision that is not really a format decision, which is whether the ad should come from the company page at all. Thought Leader Ads promote a post from a named person's profile, and they change the kind of attention the ad gets rather than the volume.

Budget logic

Budget per market, not in total. The mistake we see repeatedly is a five-figure European budget divided across eight countries, which produces eight datasets too small to learn from and one report that says nothing.

Fund two or three markets well enough to read them, then move budget to what worked. Cost per click varies enough between European markets that a single pan-European number hides the spread, so split the campaigns and let your own delivery report show you where the money goes further.

We do not publish an average CPC to plan against. The figures in circulation come from aggregate agency posts with no disclosed sample or method, and planning a budget on one is worse than planning on nothing, because it feels like information. Set a test budget large enough to produce a readable result, then scale from your own cost per qualified lead.

What two real campaigns produced

Both numbers below are ours, from named engagements, and neither is a benchmark.

For Critical Minds, a B2B management consulting firm in the Netherlands, LinkedIn campaigns ran at 8 per cent CTR and EUR 1.00 CPC. What produced that was not a format trick. It was an audience tight enough that the message could be written for exactly the person receiving it, in one market, in the right language.

For Valor, a Dutch personal wardrobe service for executives, a three-week sprint targeted executive assistants at the Top 900 companies in the Netherlands rather than the executives themselves. It spent EUR 406, produced 7,357 impressions, a 22 per cent landing page conversion rate, EUR 26.20 per conversion, and 2 qualified leads at EUR 130 each. The sample behind the 22 per cent is small and worth stating plainly: EUR 406 produced roughly 15 conversions. Read it as evidence that the targeting hypothesis deserved a test, not as a rate to plan a budget against. The full campaign, including why the gatekeeper hypothesis was worth testing at all, is in LinkedIn advertising for international B2B.

The same campaign carries the measurement lesson. Thirty-seven people opened the lead form and two completed it. On form opens it looked like a success. On qualified leads it was two conversations.

The mistakes European B2B keeps making

1. One campaign, all of Europe, in English. Dutch, German and British professionals read the same claim differently, and a single English campaign averages across the difference rather than working for any of them.
2. Budget spread until nothing is readable. Covered above, and it remains the most expensive of these.
3. Measuring form fills. Optimise toward form fills and the platform will find you people who fill in forms. Measure cost per qualified lead, meaning a lead your sales team wants to speak to.
4. Accepting the delivery defaults. Expansion settings undo the targeting work.
5. No exclusions. Paying to advertise to your own staff and your existing customers.
6. No CRM connection. Without it you cannot attribute pipeline, which means you cannot defend the budget when it is questioned.
