All WordPress blogs should have favicons (the little icon that displays to the left of the website address in your browser screen). The default WordPress favicon just smacks of amateurism. And you’re not an amateur, right?
Fortunately, installing a favicon on your WordPress site is a piece of cake. And although there are plugins available that can do it for you, such a task definitely falls into the “you do absolutely not need to use a plugin to do this” category. After all, you want to keep your site lean and mean.
