Thanks for all the info, so Matt says Google is not considering G+ as ranking factor, I don' believe this. All social media engagement have a correlation with rankings. I think now a days correlation value of Google+ is increased(this is why they index everything ASAP).
Guys Need help:
We recently faced a situation where we replaced the Facebook like button with Share button from our internet marketing blog(company site/blog).
Still I personally feel ‘Like’ was getting more engagement than share button, what will you advice for me. Implementing both Like & Share button is a good idea? I believe since our site only deals with particular industry i.e. Internet Marketing, less people will be sharing the blogs. We feel Facebook share is much valuable than Like, but we are confused here.
