Post History

The imported content may be a problem in that Google will see it as duplicate content, and Google does not like duplicate content. I'm not sure if the whole site gets actively penalized for the duplicate content, but I'm pretty sure that searches that match that content don't go here but to the other place. Someone with more knowledge of SEO that I possess should weigh in on that, but conceivably removing the duplicate content might make Google look more kindly on this site. 

And after that, I think we have to face the fact that most traffic to any site comes through search and that the other place is likely to rank above this place for a long time to come. So, making sure that the place is doing all the SEO right has to be a large part of the answer, if not the whole of it.
