1. Use text not graphics for your web design. Web pages that are loaded with graphics are not friendly to search engines' crawlers. Search engines classify and rank pages by text, not graphics.
   
   
2. Build your web page content around specific key phrases. Your web pages must have specific themes. It would be very difficult to rank high for generic terms.

You want as many pages as possible to be indexed and ranked well.
   
   
3. Organize your website internal links. You want all your web pages to be crawled and indexed by the search engines. You want to make it easy for crawlers to find your internal pages. It is best to include text links to these pages from your home page, and to cross-link all your web pages.
   
   If your navigational system uses Java-script or images, then you have to add text links at the top or bottom of your web pages to make sure that the crawlers follow all the links. Double-check all your links to verify they are working.
   
   
4. Include your key phrases at the following places.

   c. Headlines and subheadlines. Place your headlines at the top of your web pages page. Your headline and subheadline texts should be enclosed with special header tags such as h1, h2, h3.

It is not only the quantity of links that counts, but also the quality of the links. So, you will be better off with a few links from good quality web pages (those that ranked high by the search engines) than many links from low-ranked web pages.
