B2B marketing is still about reaching individuals. LinkedIn hosts the largest group of professionals online, with over 400 million members, including senior executives, opinion leaders, and decision makers. Professionals use LinkedIn to gain industry news, expert advice, professional learning, and peer insights. Content on LinkedIn receives significantly more views than job postings. Examples showed how targeted content campaigns on LinkedIn increased an influencer's followers by 1,845 in one month and helped automotive brands reach almost 2 million new buyers with trebled conversion rates. An alumni email campaign on LinkedIn also had high open and click-through rates and engagement from employees.
