There are a lot of things to be done. First you have to have a great
SEO done for you web-site (starting from defining set of key-words and having those keywords on the page at least 5% for each page), second you should run ad campaign, and the 3-d is to post articles, and other content with back links to bookmarks, and different article boards and other sources ... well it takes time for sure ..
Also I would suggest never use automatic submitters for domains registered not so long ago...
