LinkedIn Is Most Important Social Network for B2B Marketers

LinkedIn Most Important Social Network Among B2B Marketers (via BtoB)When asked which social media method is most important for their social outreach, LinkedIn was the clear winner among B2B marketers (chosen by 30%) according to new research by BtoB.  Facebook  followed with 19%, Twitter with 16%.  YouTube was significantly less popular with just 8%, and Google+ was most important for only 1% of B2B marketers.

However, when asked which channels they use most often, B2B marketers named LinkedIn, Facebook and Twitter almost equally. Other favorite social channels included YouTube, Flickr, Digg, Stumbleupon and Tumblr.

So while Twitter is used just as often as LinkedIn and Facebook, it’s considered less important – by B2B marketers – than the other two platforms.

Marketers were also asked to name the three major obstacles their company faces regarding social media adoption:

  • lack of resources was cited by 70% of respondents
  • 57% listed poorly define success metrics and key performance indicators
  • 44% blamed “lack of knowledge about social media”
  • 22% cited management resistance
What obstacles is your company facing in terms of social media adoption, and which social media platform is key for your social outreach?
