Here is a Lynda.com video up on Youtube that shows you how to add a favicon to your web site. It requires creating the favicon, uploading it and then editing your template file to add a line of code to reference the file you uploaded. This is a small thing that makes a big difference and is forgotten by some developers.
Favicons are little tiny logos. They have the icon file type .ico
PNG transparent file can used to create a favicon by going to a web site, x-icon, that will convert your file to an icon file. Assuming that you created a favicon called favicon.ico you now need to open your header.php file and add a line of code under head as shown below.
<head> <link rel="shortcut icon" href="<?php echo get_stylesheet_directory_url(); ?>/favicon.ico" />
