if you +1 a blog post - what does that do exactly?
I've been reading about this a little, but I'm not entirely sure if the search engine + and the blog post + and the gmail + account are all working together or if they're semi separate. I assume they all tie in together somehow but I have yet to find something written on this that explains it and what it does (most of the articles are how to use)
I keep hearing the +1 is good for seo but I'm not fully understanding what it does and how it works. Am I going to want the + button on every page of my ecommerce/educational website or just my blog?
thanks in advance!
