Thanks for reading and commenting James! To answer your question there are are couple examples of how Google+ impacts your search ranking: 1. Setting up a Google Authorship - This improves your "trust" score in Google's search algorithm to improve your ranking and also includes your picture from your Google+profile next to your search link in your results. This is more of a personalized view of search and usually leads to higher CTR's. 2. Google's social search - The search algorithm includes personalized search results specifically from Google Plus activity. The more relevant and content-based your Google+ posts are, the more search results you are likely to show up in.
