What sort of a news site do you run? It may sound a bit harsh, but if you're trying to make a global, or even national news site, then you probably won't make it. The competition is just too well established.
The way to break into the market is to go for a niche - for example, a specific sport, or pastime, or whatever. I assume that your website relates to a specific area, so what area is this? Promoting your website is all about ideas to increase its exposure (notwithstanding
SEO), so without knowing what the area is, it's difficult to come up with a plan. Try and have a think about your target audience, and where you can reach them with your message.
