By enabling the "show author profile below posts" option on your Blogger blog, the name, Google+ profile picture and a small description of the author of your posts will be displayed below the posts.
Once you enable the feature, it will only display on the desktop view of your blog and not on the mobile view. Nevertheless, you can make it to display on the mobile view of your blog with a little modification to your blog's template.
Enabling it on the mobile view of your blog, will definitely contribute to the increase in Google+ and followers of your blog authors.
