Google has made it easy to keep an eye on the popularity of your blog posts by adding a new section on Blogger dashboard.
This new section shows the number of +1s individual posts have received.
Today we’re happy to introduce the +1 counter, which allows you to quickly scan your dashboard to see which posts are most popular on your blog. Each time a reader clicks the +1 button on a post, a +1 gets added to that post’s counter and their profile photo and name will appear.
Google +1 button is already part of the Share button feature of Blogger. It is enabled by default on dynamic templates. It has to be manually added to regular templates.
