Make your website useful. Nice content. Niche content.
Get links from directory. High PR directory. Suggest from homepage. Eg. bid directory is a good source. I love it.
leave comment at people blog and forum. Leave signature and link.
social bookmark your site. add them to popular bookmark site. If your content is good, lots of people will bookmark it as well.
