There has been a tremendous amount of controversy along with some accusations surrounding the monopolistic behaviors and the possibility that the search giant is abusing their dominant position in the market by including Google+ signals in the SERPs. But, the fact still stands that it is their engine, they will do as they please, and if you don't like it you are not obligated to use it. But seeing how you can better your search results by using Google+ that seems to be reason enough for me. Just like you would optimize the content on your website, be sure that you optimize your personal and business page on Google+. Ensure that your profile is complete with a descriptive summary and include links to your website and other social networks so that you can cross pollinate your social sharing. Leverage your other social profiles as well, both personal and business.
