If you aren’t on Google Plus and you are trying to make money online, then I suggest you get a Google+ invite ASAP. Why am I pushing a Google+ account? For SEO, SEM and credibility purposes of course.
If you do a search for a name on Google, it looks for Google Profiles with a Google + account and displays any profiles found in the first few results, depending on the popularity of the search term. For example, searching for Jack Woods will show my Google Profile in the first few results. It displays my description, picture and a link to a few of my sites.
Now there might actually be very little SEO value in the links coming out of your profile, but I don’t think so. Google wants to build quality in its index. Right now they are using links from Twitter and Facebook and assigning search weight based on how often the link is found and the social network capital of those posting the link. I assume the same thing will be and/or is happening on Google+. Furthermore, I see them assigning more weight to certain authors in its index over time. If you are putting out quality content, here is your chance to shine.
Understand why it’s so important to have a Google+ account? Good, if you’ve got an account already, add me ( Jack Woods ) up, if not then get out there and get one right now. Make sure you also fill out your profile and include links to your best sites, it can only help you make more money if you take advantage of this.
