so you are womdering how we generate traffic to our own sites ?? :P
That's a pretty broad question that can not be answered in one post. Anything in paticular that you would like to know?
Have very strong meta tags and you can reach 2 of PR if you have a good domain. Look for other various specs like keyword density, power keyword, blockwords..etc. and you can boost your PR a little bit. Alot of backlinks helps alot, especially if the origin web site has a high PR.
