An “About” page may not be enough to stay in the competition. If you want to keep up with the pace, add an author box in your every content. Creating an author box manually may be tedious because you have to do that in every post, and does not appeal that much since its just plain text doesn’t look exactly what its trying to tell to readers. Author box plugins simplifies this task so you don’t have to worry whether your author information is placed after your content because it is automatically generated when you published a blog.
