This is another optimization tip that many people forget about. However, through use of your "alt" image attribute tag, you can slip in an extra keyword phrase or two that describes the picture users are about to see. The text only shows up when the user has turned off the 'view images' option in their browser or the image fails to load. But some search engine robots will pick it up too and the extra keywords could help your ranking. So take a few seconds to implement this optimization tip on your site and you could see improved results soon.
