1) I created 5 pages of content (Home, FAQ, About Us, etc.).
2) I put them in a simple template with site-wide links. I also linked to it from one of my other sites (it’s very relevant so it makes sense).
3) I added tagged the site on only 2 social bookmarking sites.
4) Commented in 1 forum, put the URL in one directory (niche specific), and submitted it to Digg.
5) Installed Google Analytics
6) Created a sitemap, pinged Google, and put the sitemap in my Robots.txt. Logged into Google Webmaster Central and submitted my sitemap there.
This is a great contribution.
