Hi,
My site (well its actually a blog) gets around 200 uniques per day, which for a new site is fairly ok.
So far I have been advertising as much as I can on forums and in signatures and chat rooms, I found this VERY effective. Also, alot of people have found my site through technatori which i had never used so I dont know how it got on there but its effective.
Commenting on blogs is also a very good method.
These are all very easy and simple steps to average traffic, hopefully in the near future I will be able to tell you how to get hundreds of thousands, but not yet.
Thanks,
Shane
