I don't bother with keywords mostly. As far as I can tell, they don't do anything. How do search engines rank sites? By links. How many pages do you link to on your site, and more importantly, how many other sites have links to yours. Search engines just use spiders, which are effective but stupid. They collect the various links and the more there are the more popular they think your site is.

Talent is God's gift to you. Using it is your gift to God.
