Also, never ever submit your site to Google. You'll end up in their "sandbox" rather than simply letting the Google spider do what it was made to do.
Create excellent content-filled pages that center around high-demand, low-supply keywords. Remember your Title, Keywords and Description META tags, using that page's keyword and some long-tail stuff. Add the keyword sparingly through your page and you're good to go.
Or.....
Use Site Build It like I do and forget everything I just said!
