Short question with long answer...
There is a LOT of work getting your site to be seen on Google if it is not being hit by natural traffic. We would all love to have our site on the first page of Google (and often pay for customers for it to happen).
Suggest you start here
http://www.google.com/addurl/ to get your sie crawled by Google for a stasrt. There are other methods as well.
Read the forums here and elsewhere on Search Engine Optimization (SEO) this should give you some pointers on how to make sure your site shows up on Google searches.
I could go on but do some reading first on at least the topics above.
Also can you clarify what your site is about?
