The "30 day trial" concept has been abused by scammy internet marketers to a point where I don't think people trust it as much, especially for a new or relatively unknown product. Does your product work by any chance as a freemium model? I've had better luck with this than 30 day trials. It combines the best of both worlds: a free product that requires no credit card to demonstrate the usefulness, but a premium version which requires credit card right away.
