Easy promotion and traffic

Once a blogger has formed a network on twitter that is interested in the same topics that he writes about, then you got the perfect channel to promote your writings. If I take myself for example I follow (and get followed by) people interested in Social Media, Business and Design. This way of communicating directly to your niche, might explain the high click through rates on twitter. I once tested how many people would click a link in an ordinary messages using bit.ly, that offers detailed statistics on the clicks you get. It turned out that of the 100 followers I had 6 clicked the link within 10 minutes of each other.

Time value of your tweet

Analyzing the clicks with bit.ly showed that the traffic you get from tweeting a link are within a time span of 10 minutes, so the value of your message is of limited time. This is because of the way the main twitter feed works. The feed is real time, and messages that are old are not likely to be viewed by any followers.
