i have been experimenting various methods of tapping traffic on hourly basis and realized that Twitter is far much effective source. My method involved publishing a breaking news item on my news wesbite 'Cable News Corp' and then discussing it on twitter. Google indexed the top discussions on Twitter and i found hundreds of those searching for the keyword 'cuba 5.6 earthquake strikes in eastern cuba' landed on my site. Those publishing news can try this and see if it will work well for.
it is easier working hard to market a site using your own means than buying traffic. Most of the traffic you purchase is not human. I purchased traffic sometime ago and i was frustrated since the traffic hardly brought any profitability. The pattern showed that he traffic was coming from the same source and could hardly go beyond the homepage. Twitter traffic shows interest on your pages and you can use analytics to evaluate how the traffic has clicked on your pages and ads. Use twitter, Facebook, Digg and DP to get traffic.
