LinkedIn ads for B2B

How LinkedIn targeting actually works

LinkedIn targeting is built on profile data that members maintain themselves for professional reasons, which is why it holds up better than inferred targeting elsewhere. You can reach people by job title, seniority, function, skills, company size, industry, named company list, and membership of groups.

The practical advice is to pick one primary attribute and add at most one qualifier. Job function plus seniority is usually stronger than job title, because titles vary wildly between companies and a title list will always have gaps. Function plus seniority catches the head of marketing, the marketing director and the VP marketing without you having to guess at every variant.

Watch out for audience expansion and the LinkedIn Audience Network, both of which are on by default and both of which will widen your targeting past what you chose. On a B2B budget that matters. We turn them off at launch, measure the core audience honestly, then decide whether widening is worth it.

• Job function plus seniority beats a long job title list
• Company size and industry keep the audience commercially relevant
• Turn off audience expansion until you know what the core audience does
• Aim for an audience large enough to deliver, usually tens of thousands, not thousands

Account-based targeting and matched audiences

If you sell to a defined list of companies, upload it. LinkedIn will match your company list against its own company pages, and you can then run campaigns against only those accounts. This is the closest thing in digital advertising to buying attention from a specific boardroom.

Match rates depend on how clean the list is. Company names alone match poorly because of trading names, legal suffixes and subsidiaries. Including the company website domain lifts the match rate substantially. Lists need a minimum size to activate, so very short target lists need combining or widening.

Once the list is live, layer job function and seniority on top so you reach the buying committee rather than everyone at those companies. Then build a second campaign that retargets anyone from those companies who engaged, because in account-based selling the engagement signal is the thing sales actually wants.

Which LinkedIn ad format for which job

Single image sponsored content is the reliable default. It appears in feed, works for both lead forms and site traffic, and gives you enough space to make a real point. Document ads, where a multi-page PDF is swiped in feed, tend to perform well for research and guide content because people can judge the value before giving details.

Video works for building familiarity rather than for direct response. Thought leader ads, which promote a post from a person rather than the company page, often outperform company posts because they read as a colleague speaking rather than a brand broadcasting. Conversation and message ads land directly in the inbox and can perform strongly, though they need a genuinely useful reason to be there.

Text ads and spotlight ads sit in the right rail on desktop. They are cheap and easy to dismiss, so treat them as low-cost support for a campaign carried by feed formats rather than as the main event.

• Single image sponsored content: the dependable workhorse
• Document ads: strong for guides, benchmarks and frameworks
• Thought leader ads: a person's voice usually beats a brand's
• Message ads: high visibility, needs a genuine reason to be in the inbox

Making the B2B economics work

LinkedIn clicks cost more than almost anywhere else, so the maths has to start from the deal, not from the click. Work backwards: average deal value, close rate from a qualified lead, and how many leads you need. That gives you a cost per lead you can genuinely afford, and it tells you quickly whether LinkedIn is viable for your offer.

As a rough guide, LinkedIn tends to make sense when a customer is worth thousands rather than hundreds, and when the buyer is identifiable by role. A product with a low ticket price and a broad audience is usually better served on search or Meta, and we will say so rather than take the budget.

Long sales cycles also change how you judge results. If your deals take six months, the campaign that looks poor at week eight may be the one filling the pipeline. Measuring pipeline created rather than leads generated is the difference between managing this channel well and switching it off just as it starts to work.

Bidding and budget on a smaller audience

LinkedIn offers maximum delivery, cost cap and manual bidding. Manual bidding gives the most control and is where we usually start, because it stops the platform paying top of range while it works out what your audience is worth. Cost cap is useful once you have a proven cost per lead and want to hold it while adding budget.

Daily budgets need to be realistic against the audience size. A very small audience with a large daily budget forces frequency up quickly and burns the list. LinkedIn also spends slightly over the daily budget on strong days, so set the number with that in mind.

Campaign objective matters more than people expect, because it changes who LinkedIn shows the ad to. A traffic objective finds clickers. A lead generation objective finds form completers. If you want leads, do not run traffic and hope.

• Start on manual bidding to learn the real clearing price
• Move to cost cap once you have a proven cost per lead
• Match the objective to the outcome, not to the traffic you want to see
• Keep daily budget proportionate to audience size to control frequency

Lead quality, CRM handoff and the feedback loop

Lead gen forms pre-fill from the member profile, so they convert well and cheaply. The risk is that a two-click form attracts people who were mildly curious. The fix is not to abandon forms but to add friction where it filters usefully: a qualifying question, a custom field, or an offer that only appeals to someone with the problem you solve.

The handoff matters as much as the form. Leads should flow into your CRM automatically with the campaign and creative attached, so that three months later you can see which campaign produced deals rather than which produced downloads. Leads sitting in the LinkedIn interface waiting for a manual export go cold and lose their source data.

Then close the loop. Once you can send qualified and closed statuses back, you optimise towards the campaigns that produce real pipeline. In our experience this often reorders the ranking completely, and the campaign with the highest cost per lead turns out to be the one worth scaling.

• Add one qualifying question to filter the merely curious
• Sync leads to the CRM automatically with campaign attribution attached
• Contact speed matters, a lead worked within the hour converts far better
• Judge campaigns on pipeline created, not on form fills

Retargeting and the case for a longer sequence

B2B buyers rarely act on a first exposure, so the retargeting layer is where LinkedIn budgets usually earn their return. Build audiences from website visits, video views past a meaningful percentage, lead form opens that were not completed, and company page engagement.

Sequence the message by depth. Someone who watched a quarter of a video needs a different ad to someone who opened your pricing page and left. Early stage retargeting should keep teaching. Late stage should make the specific case and ask for the meeting.

One overlooked move is retargeting people who engaged with the ad itself. LinkedIn lets you build audiences from ad engagement, which means the money you spent reaching cold prospects produces a warm list you can work again at a fraction of the cost. For an expensive channel, that reuse is what makes the budget stretch.
