Favicon
Favicon is short for favorites icon. It's the small image or logo that you see in your address bar when you visit a website. You should be seeing a small "FW" in your address bar for Fierce Websites.
You can have a favicon for your website. It's simple. Speaking of simple, it's best to keep your favicon image as something recognizable, but not too intricate.
Create your own by visiting the Favicon Generator.
You do not need to put <link rel="shortcut icon" type="image/x-icon" href="/favicon.ico"> in the head section of all your pages as suggested, to have your favicon appear. Do upload it to your root folder. It should appear for any of your site links. However as you probably know, browsers can be tempermental and there may be times it does not show.
