Every blogger want to show the author details on their blogs. That widget is commonly said as 'About-me' widget. New visitors to our site want to know more about it before they determine whether or not it’s worth clicking around.
Look here, what I recommend including in those few sentences that can write on about me page for better understanding.they are A link to your full About page,about you,what you doing and your social profile id's. Here I'am showing a simple author box with massive effect. It is my personal author-box widget that i use in my blog.
