You really could do to set up reciprocal links with other sites in a similar field. The more inbound links that your site receives, the higher it's perceived relevancy by the search engines. If you want to link Sysxtreme to my company's website (we do computer spares), visit http;//www.totis.co.uk click on the links text button at the bottom right hand side of the home page and fill in the form. I'll get you added.
Also, make sure that you register on as many web directories as possible. The main one is
www.dmoz.org.
You need to make your home page "spider friendly", so make sure your meta tags are filled with relevant keywords (not just random crap).
