This question has been asked so many times from so many people,
well you can try submitting your website to google, that improves it a bit, but to drastically improve traffic on your site you need to do some hard work, leaving a site motionless never helps, you must post a different thing every day, get users interested, there is no point with adwords from google really because no one actually really goes on to the site they just click on accidently and say, stupid add and shut it again!!!
