1. Research keywords.
2. Use two of your main keywords in home page title (tag)
3. Try to use both keywords in description (tag)
4. Use both in keywords (tag)

5. Use your main keyword in heading once.. I mean in h1 tag. (if it's to big, use css to customize its size)
6. Use your second keyword in h2 tag heading once.
7. Bold your keywords when you can on page.

Use your keywords in any text that you write on your website.. Your keyword score should be at least 1%.

Sorry for my English

Yes there is a lot more to it ... i am sorry i don't have a link of any decent ebook that i can post here but i'll try to find and post a link later meanwhile here are few tips that would help.

1 - Use the keyword in page title tag (don't use same keyword for title tag on all pages of your website)
2- Maintain a good keyword density (you can use this tool to check keyword density.)
3 - Bold your target keyword a couple of times in the text
4 - Use keyword as heading once
5 - Use keyword in Alt tag
6 - Use keyword as anchor text in your internal links.
7 - Submit a sitemap to Google Webmaster Tools, you can create a XML sitemap with this tool.
8 - Don't over do step 2 and 3

This is all i can think of right now ...
