Focus on one keyword per page.
Make sure you underline, italicize, and bold your keywords at least once.
Have your keyword in your H1, H2 and H3 tags preferably at the front of each title.
Try to keep your keyword density from 1 to 3%, anymore and it may be considered keyword spam.
Have your keyword listed in your title.
I do hope these techniques help you out.:) There are also some great authors here on Hubpages that write some awesome must read SEO articles. Just do a search on the search bar on Seo and Hubpages.
