Favicon is really a 16 X 16 small graphic icon that appears within your browser address bar beside a web site domain name. Also, it is known as a shortcut icon, website icon, bookmark icon or maybe a URL icon. Its gives branded look for your website and makes it stick out. By default in all blogger blogs you see a small orange icon
that shows next to all subdomains with BlogSpot as the extension. Even those who have purchased domains see that orange icon as the default favicon. Most of your might have observed that your custom favicon displays in both Firefox, chrome and other major browsers but you can not see favicon appearing in Internet explorer instead you see the same orange icon.
