If you’ve joined Google+ - or if you're an SEO or webmaster waiting to get in – you probably want to know how Google will rank posts and/or links on the new social network. We already know that Google gives ranking weight to links on Facebook Pages and that it receives a Twitter feed that is stripped of the nofollow attribute. We know links are even more valuable when they come from a Twitter user whose posts are often ReTweeted. We know Facebook has an algorithm (called EdgeRank
) to determine which posts you see in your stream. So, how will Google determine the relative ranking value of posts. For example, does the name you give a circle [the mechanism for organizing your contacts and determining who sees what and whose posts you see (Exploring Circles
) inform Google on the relevance of posts to that circle?
Chatter on G+ certainly reflects this question and similar questions A few days ago, William Slawski, an SEO best known for his analysis of Google and other search engines patents, posted on Google+:
One of the very interesting things about Google + is the freedom of people to use whatever names they want for the Circles they place people within.
Information about the names of those Circles may be data Google can use to learn about relationships between people in the Google social graph. They might also be used as possible annotations or meta data to label people based upon expertise (designers, SEOs, journalists, etc.), or location (local, newyorkers, houston, fauquier county, etc.), or in other ways.
Those labels could potentially be used as a signal, in combination with others, about how particular individuals’ Google + posts might rank in search results. The strength of those signals might rely in part upon the reputations and credentials of the people creating the circles, so that the weight of each might be different.
Slawski followed up on that stream with two relevant and informative blog posts:

Both are well worth a read if you’re interested to know how Google+ may influence SERPs.
