Thanks Christopher and Luke. If I understand it correctly, it might help a bit,.. but it does not pay off big time 
Luckely the social traffic is also important on it's own.
Which social media do you use?
I am pretty sure Google+ becomes more and more important. But here in the Netherlands nobody uses it, except SEO marketeers How is this in the USA @Christopher Glaeser? And Luke, in your country?
