The most popular social media sites for distributing B2B content are LinkedIn (used by 83% of B2B marketers), Twitter (80%) and Facebook (also 80%).

Using social media boosts website traffic: companies gain a 185% lift in Web traffic after achieving 1,000 Facebook likes, and businesses with 51 to 100 Twitter followers generate 106% more traffic than those with 25 or fewer followers. (MarketingProfs)
