Guys i found a good trick for seo over internet.In this trick you basically create a favicon.ico file. A favicon is a small 16 x 16 pixel icon that is displayed when you bookmark a page and add it your Favorites. Place this file in the root directory of your server and you can track how many referrals are coming from people that have bookmarked your site. Favicons are created with special software that creates the correct file format. They are also great for branding purposes.
