请高手帮忙! How to get my website high in google search result?

My website is a formal one with meta tag to optimize the search results. In my domain name, there are two concatenated strings: xxxxxxxyyy.com. When I use xxxxxxx as a keyword to search in google, it won't show. I tried yahoo and msn, all the same, - no show.

I think my domain should be on the 3rd on google search result. The first one and second are: xxxxxxx.com and xxxxxxx.net. Mine should be in third logically because mine is xxxxxxxyyy.com. There are no other domains having string of xxxxxxx.

Now what do I need to do to resolve this issue? I emailed to google, yahoo and msn to inquire but couple days past no words.

Any advices are appreciated!
