i got PR5 for http://hotnews.tblog.com but its daily traffic is just 10 or 15...how to increase the traffic???...or whats the problem with my blog?
well, increase you link popularity, directory submissions, buy links, surf arround the forums, you may have pe 9 and 20 visitors, the PR is not visitors related.
Have you done any keyword research? Are you targeting keyphrases that people are actually searching for and are you actually ranking well for them? Having PR5 will not necessarily help you.
Use tools like keyword discovery, wordtracker, overture etc. They will give you search counts for each phrase and will suggest alternative phrases for you.
