Be bold. Use the <b> </b> tags around some of your keywords on each page. Do NOT use them everywhere the keyword appears. Once or twice is plenty.

Deep linking. Make sure you have links coming in to as many pages as possible. What does it tell a search engine when other web sites are linking to different pages on your site? That you obviously have lots of worthwhile content. What does it tell a search engine that all your links are coming in to the home page? That you have a shallow site of little value, or that your links were generated by automation rather than by the value of your site. Here is an example of deep linking, in this case to my personal happiness workbook.

Become a foreigner. Canada and the UK have many directories for websites of companies based in those countries. Can you get a business address in one of those countries?

Social bookmarking. Make it easy for your visitors to social bookmark your website, creating important links that the search engines value. There are plenty of free social bookmarking widgets available.
