Checking search trends in torrentz.com.

Is there a way to check the no of searches performed for a particular keyword at torrentz.com or any other torrent site.

I am asking this question because I would like to do a torrent campaign and before that I would like to know whether it is worth it.

go to isohunt.com, you'll get top 300 most searched keyword

Got it isohunt Zeitgeist.
