LinkedIn ads: which formats exist and when to use which

LinkedIn ads are often the sharpest channel there is for B2B, precisely because you can target with surgical precision on job function, industry and company size. But “creating a LinkedIn ad” is not one single thing: there are several ad types, each with its own role in your funnel. In this article we run through the formats and tell you, per type, when it pays off and when it does not.

Why the ad format matters so much

On LinkedIn you pay a premium for reach. Click prices are higher than on most other channels, so every wasted euro counts. Choosing the right LinkedIn ad format largely determines whether your budget pays off or evaporates.

The mistake we see most often: picking one format (usually boosting a simple post) and hoping it solves everything. Strong campaigns combine formats, matched to where your audience sits in the marketing funnel.

Sponsored Content: your workhorse

Sponsored Content means ads in the feed: single image, video, carousel or document ads. This is the most used type and, for most B2B companies, the starting point.

When to use it:

• Single image for direct offers and lead campaigns.
• Video to build trust with a cold audience.
• Carousel to explain a process or several benefits.
• Document ads (a whitepaper or guide in the feed) to collect leads in exchange for value.

Document ads work particularly well in the MOFU stage, where your prospect is orienting themselves but is not yet ready to buy.

Message Ads: straight into the inbox

Message Ads (formerly Sponsored InMail), part of the format line-up for LinkedIn ad campaigns, land in your audience’s inbox. They feel personal and have high open rates, but they are expensive per send and quickly come across as pushy.

Only use them if you have a concrete, relevant offer: an invitation to an event, a demo or a personalised offer to a narrow audience. For broad awareness this format does not pay off. We advise against it while your proposition is not yet sharp, because then you burn goodwill instead of winning leads.

Lead Gen Forms: less friction, more leads

Lead Gen Forms are not a separate channel, but a format you attach to Sponsored Content or Message Ads. The form opens inside LinkedIn itself and is pre-filled with the user’s details.

The result: far less friction and a higher conversion rate than a landing page on your own site. The downside is that the lead does not always see your website, so you miss out on context and warming up. Our rule of thumb: use Lead Gen Forms if volume and cost per lead are your priority, and send people to your site if explanation and trust matter more.

Text Ads and Dynamic Ads: the quiet players

Text Ads sit in the sidebar on desktop and are dirt cheap per click. They rarely deliver much volume, but they are useful as cheap support alongside your main campaigns.

Dynamic Ads personalise automatically with the user’s name and profile picture. They stand out, but the effect varies a lot per audience. Both types are additions, not foundations. Do not start with them if you do not yet have Sponsored Content running.

Overview: which ad type for which goal

LinkedIn organises its formats into a few families, as you can also see in the official overview of ad formats. This table summarises what each type is strongest at.

Targeting: where LinkedIn stands out

The reason you pay that premium on reach is the targeting. No other channel lets you choose so precisely on job title, seniority level, company size, industry or even specific companies and member lists via Matched Audiences. In practice we see that most budgets do not evaporate because of the wrong ad type, but because of an audience that is too broad. Start narrow (one job function, one industry), measure what lands and only widen when the numbers justify it. The common mistake is the opposite: wanting to reach everyone and driving up your click price without the leads becoming any more relevant.

Budget: what to take into account

LinkedIn applies a minimum budget per campaign and click prices are structurally higher than on Search or Meta. So do not count on volume, but on quality: one meeting with a decision-maker weighs more than a hundred cheap clicks. What you will realistically spend depends heavily on your industry and audience. If your offer is not yet sharp, or your audience is broad and low-value, a comparison between Google Ads and LinkedIn Ads for B2B is an honest check before you put budget into this.

What we recommend for most B2B companies

You do not have to do everything at once. A build-up that works in practice:

• Start with Sponsored Content (single image and video) to reach your audience and learn what lands.
• Add Lead Gen Forms or document ads as soon as you know which message works.
• Scale with carousels and possibly Message Ads to your warmest segments.
• Support with Text Ads as cheap extra visibility.

Steer on customers, not on impressions

Whichever type you choose: the pitfall is steering on vanity numbers like impressions and likes. They say nothing about your revenue. We look at qualified leads and customers, and we are willing to tell you honestly when LinkedIn ads are not the smartest first move in your situation.

Sometimes the win is not more budget, but sharper targeting. In an account-based marketing project, that delivered 189% more MQLs, at 22% lower monthly costs.
