LinkedIn

Dominant leader in B2B digital advertising with the world's largest verified professional identity graph

LinkedIn is the world's largest professional networking platform with over 1 billion members across 200+ countries. Founded in 2003 and acquired by Microsoft in 2016 for $26.2 billion, LinkedIn has evolved from a professional resume and networking site into one of the most powerful B2B advertising ecosystems in the world. Its advertising solutions allow marketers to target professionals with unmatched precision based on first-party data including job title, company size, industry, seniority, skills, and more. LinkedIn's advertising platform includes Sponsored Content (native ads in the feed), Sponsored Messaging (InMail and Message Ads), Dynamic Ads, Text Ads, and a robust Campaign Manager interface. The platform also offers LinkedIn Marketing Solutions, which encompasses lead generation forms, website retargeting, lookalike audiences, and conversion tracking. LinkedIn's Audience Network extends reach beyond the platform itself to third-party publishers. In the AdTech ecosystem, LinkedIn occupies a unique and defensible position as the only scaled professional identity graph with verified employment data. This makes it indispensable for B2B marketers, enterprise software vendors, financial services firms, and recruiters. LinkedIn's revenue has grown significantly under Microsoft's ownership, with LinkedIn revenue surpassing $15 billion annually. It competes with Meta, Google, and programmatic DSPs for B2B ad budgets but differentiates through the quality and accuracy of its professional audience data.
