I get a lot of questions about whether or not to invest time in the Google+ social layer. Normally, I suggest that the answer to the question of “which social networks to use” is customer-focused. That is, learn where your customers are, and then focus energy on those social networks. Google+ might be a useful exception to this rule, however. If Google is responsible for a lot of traffic to your website, and if SEO matters to you, then I think it would be wise to invest some energy into Google+. This post offers some useful ‘quick steps.’ You should of course have a strategy for Google+ that extends beyond these tips, however.
