Some years ago a keyword expert named Dan Thies wrote a fabulous free guide to learning SEO (search engine optimization.) He has since updated it and if you feel hazy about SEO you really should download his free guide. There's no opt in or anything, you can just grab the PDF here at his site:

Also I have an article up about SEO and how you should use certain plugins for your WordPress blog if you want to get it spidered well by the search engines:

Don't be intimidate by SEO. It's just a matter of learning how to do a few things consistently to improve rankings on your site. Anybody can learn, especially if they do a little reading on it and check out a free guide like Dan's.
