Nowadays, we know SMO by using Google+ (and Facebook, Twitter...) is good for SEO and ranking in SERP.
Then, I would like to use Google+ to optimize my new website SEO but I don't know how can I begin to use it.
I already associate my website with my Google+ profile to get my face in SERP of Google and it works fine.
But now?
I suppose I should make a community grow around my website.
Should I begin a blog with relevant texts, images etc. for visitors and link all my blog posts with my Google+ profile?
How can I use Google+ to optimize my new website SEO?
All suggestion can be useful.
