The first place to start in learning about SEO is right from the source - not from the random know-it-alls here who have already given you outdated advice that would cause more harm than good.

Check out Google's Webmaster Guidelines: http://support.google.com/webmasters/bin...swer=35769
and SEO Starter Guide: http://static.googleusercontent.com/exte...-guide.pdf

And a few non-Google sites that have really good information:
