Lets look at the anatomy of a well optimized page.
You should try and optimize each page for only one keyword or phrase.
Only use keywords that will actually show up as text on the page to avoid keyword stuffing.
Does not facture in Googles algorithm but can affect your CTR on the Search Results page.
Try and use a H1 tag as close to the top of the page as possible. Use the same keyword/phrase used in the title tag.
On page optimization is the easy part of SEO (Search Engine Optimization) It really comes down to proper code structure and focusing on targeted keywords and phrases. The hard part is building links to your site. I said hard but not impossible. I will cover this topic at a later date.
