B2B
- Twitter
- Facebook
- Linkedin
- Google+
The four main social media platforms you should be using if you're in B2B are Twitter, Facebook, Linkedin and Google+.
Google+ is a strange one since no one uses it due to it being horribly unuser friendly. However, posting on it will help with Google rankings so my advice would be that if you post a link on any of the other 3 platforms, post the same link on Google+ anyway and it will be helpful for your rankings. The good thing about Google+ is that it requires little to no maintenance; just post and forget about it.
