Pretty much do what these ppl have already posted. Some sites I post my articles to: ehow, squidoo, ezinearticles, and hubpages. Some social networks I post to: Faves, digg, mixx, and folkd. Make sure you don't post the same title everytime mix it up a bit. You should be focusing on a couple of key phrases anyways.
start making back links for your website, back links can help you to get your website up in search engines, try it
I agree with Manny,Try to build quality back links Also use Social Bookmarking,Directory Submission,forum posting etc to improve SEO in google search
You need to do complete seo of your site in order to get higher ranks in google, seo is not a simple thhing which you can do in a day or two....it can extend up to months and years and then give some results.....there are lot of different ways and many companies specialize in providing such services......so you need to get it done from a professional if you are not an seo expert.....
