In terms of total conversions, 165 isn't really enough to make a good judgment on. I would say that your ballpark conversion for Clickbank would realistically be around 1:500 for "general" traffic (ie. not super targeted PPC type traffic).
Also 2012 is a pretty shitty niche to be in because most of the people who are into that stuff are fringe loonies and not necessarily buyers... The highest converting niches are ones where you can offer people a solution to really pressing, immediate problems.
However, the fact that 0 people out of 165 have clicked through to the order form is a strong clue that the sales page sucks and I would consider switching products.
Really you need to mainly work on traffic so you can get more data faster, so you can make more informed decisions.
