Most people are unaware of the power of Google+ and have a profile because they heard that it is useful for search engine optimisation (SEO). Being a fairly new social network, on Google there is camaraderie that is rarely felt in more established networks. You can join communities (types of forums for different interests), host hangouts, troubleshoot technical problems, or do subtle product promotion. Social updates will rank on Google, and search results will feature in the top pages in your followers’ search results.
