Many thanks thegrif. I'm actually quite experienced with PPC - though admittedly in completely different industries to this one - and it had occurred to me before I started that PPC was simply not a viable strategy for this particular market. Having said that, I'd still expected to get a lot closer to break-even, and the fact that more people aren't clicking through to the various theme description pages (regardless of whether they're actually buying or not) makes me think I've screwed something up on the ux side of things, particularly as the traffic coming in should be pretty highly targeted. As I mentioned in my initial post, the fact that I personally would still use something more conventional (like themeforest) to find a new theme makes me think I am missing a crucial piece of the ux puzzle.
