Search Engine Optimization

• Get as many different sites in the search engine as you can.
  You can see which of your site is in the search eningne.
  By using the e.g.(google) "site:www.yourdomain.com yourdomain" syntax.
• All of these sites should contain a link to the sites you want to rank high. Many sites do this with a menu. Prefer includes for a menu - frames suck here the most. With a frame menu you have only one site linking to your main sites thats really bad.
• Avoid using "home" as a anchor text or something like that for sites you wan't a good ranking. If the design can't afford changing these words for linking use images. Here you can add alttext (alt="keywords") which is nearly as good as real text.
• Old Search Engine Optimization also influence your ranking so keywords in
  • the metatitle <title>...</title> and
  headings <h1>...</h1>
  as well as an average keyword density (frequency of one keyword divided by number of words total).
  here you can check it:
  keyworddensity.com
  keywordcount.com
  will do a nice boost in ranking.

• anchor text going to your site from the main directories.
  dmoz.org yahoo.com looksmart.com
• link text from other sites.
• how you link (e.g. to your main site 'home') within your site.
  If you have 2-3 domains with many sites in the search engine index.
  And all link with the same link text to a site. You can go to the top without directories and links from other sites.

• pagerank and algorithm similar to that.
