Folks at Blizzard Internet Marketing wrote a very good beginner's SEO guide to Wordpress. I shared some of my thoughts and they were kind enough to put in on their Update section of the post. Check it oot! There are tons of SEO guides for Wordpress and I read any I can find because there's always that one tiny bit of tip that skipped someone else's list. Always, always read everything you can. Then discard all that doesn't work for you.
