F) Page Size
The less kilobytes your page uses, the better - especially for the home page. Optimize your images and make sure the page loads quickly. Most people and businesses in the Western world may have high speed, but cell phones and other countries might not. If your site loads slowly, you may have already lost your visitor before they've even had a chance to browse around.

G) Usability
Make sure that your site follows good usability rules. Remember that people spend more time on other sites, so don't violate design conventions. Don't use PDF files for online reading. Change the colours for visited links, and use good headers. Look up usability for more tips and tricks, it will be worth your while.

H) On Site Optimization
Use the keyphrase you have chosen in your title (most important), your headers (when appropriate), and within the text. Make sure that your page/content is ABOUT your keyphrase. If you are selling widgets, than write about widgets. Don't just stick the word widgets into the text.

I) Globals
Globals are the links that remain the same on every page. They are the reference for new visitors to keep them from getting lost. Sometimes they are on the left of the page, sometimes they consist of tabs at the top. Often they are in the footer of the page as well. Make sure that you have an old style text version of your globals on every page. I usually create tabs at the top, and put the text versions in the footer at the bottom of the page. Find out what works best for you.

J) Headers
Use bold headers. On the Internet, people scan they don't read. So initially, all they will see are the headers. If your headers don't address their concerns, they won't stick around long enough to read your content. Use appropriate keyphrases when you can.
