Types of LinkedIn Ads: A Complete Guide for B2B Marketers

In the world of B2B marketing, precision is the difference between a wasted budget and a high-quality pipeline. As of 2025, LinkedIn has solidified its position as the premier platform for professional engagement, boasting over 1 billion members and 65 million decision-makers. For marketers, understanding the various types of linkedin ads is essential to reaching the right people at the right time.

Why LinkedIn Ads Matter for B2B Marketing

LinkedIn is not just a social network; it is a professional database with unmatched targeting capabilities. Unlike platforms like Meta or TikTok, where user data is often based on personal interests, LinkedIn provides accurate “firmographic” data. This allows you to target users based on their exact job title, seniority, company size, and specific industry.

The Leading Platform for Professional Targeting

According to industry benchmarks for 2025, LinkedIn is responsible for 80% of all B2B social media leads. The platform is specifically designed to support the professional mindset, making it the ideal environment for lead generation, thought leadership, and recruitment.

Full-Funnel Growth

Different types of linkedin ads serve different stages of the buyer journey. Whether you are building top-of-funnel awareness through video or driving bottom-of-funnel conversions with Lead Gen Forms, LinkedIn provides a cohesive ecosystem to move professionals from discovery to a closed deal.

The Main Types of LinkedIn Ads

Selecting the right format is the first step toward campaign success. Here are the primary categories available to B2B marketers today.

1. Sponsored Content

These ads appear directly in the LinkedIn feed. They are the most versatile for driving engagement.

• Single Image Ads: The “bread and butter” of LinkedIn advertising.
• Video Ads: Essential for product demos. Note that according to LinkedIn Marketing Solutions, videos under 30 seconds see a 200% higher completion rate.
• Carousel Ads: Ideal for step-by-step guides or showcasing multiple product features.
• Document Ads: A top format for Lead Generation. These allow users to read and download whitepapers or case studies directly in the feed without leaving the app.

2. Thought Leader Ads (2026 Trend)

This is one of the most powerful additions to the LinkedIn ecosystem. Thought Leader Ads allow brands to “sponsor” or boost posts from the personal profiles of their CEOs, employees, or industry influencers. This builds a layer of human trust that corporate brand pages often struggle to achieve.

3. Sponsored Messaging (InMail)

Delivered directly into a member’s LinkedIn Inbox, these are high-impact but require a delicate touch.

• Message Ads: A direct, personalized message.
• Conversation Ads: A “choose-your-own-path” experience with multiple response options.

Best Practice: Use Sponsored Messaging only for exclusive invitations like Webinars or VIP events. LinkedIn imposes strict frequency caps to prevent spam; if your message doesn’t offer immediate value, your “Cost Per Open” will skyrocket.

4. Connected TV (CTV) Ads

The newest innovation in LinkedIn’s arsenal, CTV ads allow B2B brands to reach professionals on their home televisions. This is a game-changer for top-of-funnel brand awareness and high-level executive targeting.

How to Choose the Right LinkedIn Ad Type for Your Campaign

To maximize your Return on Ad Spend (ROAS), you must align your format with your specific marketing objective.

• For Awareness: Use Video Ads or Single Image Ads to introduce your brand to a broad but relevant audience.
• For Consideration: Use Carousel Ads or Document Ads to share deep-dive whitepapers or case studies.
• For Conversion: Always utilize Lead Gen Forms. They eliminate the need for users to leave the platform, which increases the likelihood of a submission.

When setting up your targeting, focus on “Job Function” combined with “Seniority” rather than just job titles. This ensures you do not miss decision-makers who might have unique titles within their organizations.

Conversion Tools: The Power of Lead Gen Forms

Rather than a standalone ad type, Lead Gen Forms are an “add-on” that can be attached to Sponsored Content or Messaging. They use pre-filled data from the user’s profile to reduce friction.
