Hi Looney,
I have written a few *very* general SEO topics on my small business website blog:
Small Business Website Blog
You are welcome to comment or ask for clarification, I could really use the feedback since it is so new!
I have written this from a business owner's point of view, and really explaining in general terms what things mean and why you need them.
The main thing that I see boost site's SEO rankings is when you submit a sitemap. It really is not "OK" to assume that google and other search engines can actually reach (!) every page on your site, so submitting a sitemap with all of your URLs defined and how often they change tends to be the highest performing thing you can do initially.
Hope this helps!
