Notes:
Two imporant badge you can’t miss: (1) Profile badge and (2) Share badge. Share badge is very useful to boost your blog popularity. If you’re blogging using blogger / blogspot, see the sample placement here. Facebook Share is like voting for your blog. Everytime someone clicks the Share button, the number will increase. If you click the Facebook Share button on the blog’s frontpage, it means you vote for the blog. If you click the Faebook Share button when you are reading an article of a particular blog, you vote for the article not the blog; so the number will be added for the particular post / article.
