"catalunya is one of the few terms that I do well on. I chose catalunya because the search volume was far higher than catalonia but probably no the best rationale"

Sadly thats prob why your sales are low as their looking for something different to what your site offers. Its better to get low targetted traffic than high general traffic.

Check your log files and see what language your visitors use, if its not English that will again show why you get low rev.

Do a test with someone like Crazy Egg – visualize your visitors to see where people do click and find possible faults in your design / layout. For example in one of my sites I found people where clicking in mad places, so made them links tot eh bookings page and saw rev go sky high.
