For some time now, some Google web search results have revealed the Google+ information of the author. This is a feature that is possible for any site that clearly indicates its content’s individual authors (mostly news sites and blogs).
So how do you link your Google+ account to your content? Well, I wanted to do it myself, so I did a little searching and found this helpful Google page that spells out everything you need to do to link things up. It turns out that there are a couple of ways of doing it.
If you regularly author content on a site, I would highly recommend linking your Google+ account. It will make it easy for Google Plusers of like interests to find and circle you. Being added to more Google+ circles obviously gives your content even more exposure.
