I’m a light G+ user. From an SEO and B2B point of view it is my preferred social platform,partly because it allows me to decide, with greater flexibility, what to share and with whom. Though it has does have SEO benefits that Facebook doesn’t, for many the jury is still out on the real value of G+ as a means to promote your business. Personally I think it’s value will grow as the platform develops and the latest development is vanity urls now open to all (who meet the criteria).
