Associating Your Blogger Page with Your Google+ Page

We recommend that you connect your Blogger page with your Google+ for many reasons from being able to manage comments form one location to helping with the indexing of your blog pages themselves.  It is just a good idea all the way around.

Integrating Google+ Comments with Blogger

Google+ Comments is an alternative to the default commenting system on Blogger, available to blog authors who have upgraded their Blogger profile to Google+.  Google+ Comments lets you bring the conversations together in one place, right under your blog post.
