I think the pricing page is giving you a high ctr % because it's really the only option for a visitor to understand the product.

Perhaps you should work on your template and include a simple features page as well. CTR from features -> pricing would be more meaningful than what you have atm. The very best measure though is email subscribe opt-ins (bonus points for double opt-ins).

Although you should really have a statistically valid number of uniques to qualify the idea (a few k). Keep working on your process and generating more ideas and you'll find something with market fit!

Depends on how little. 0.5% is not an unreasonable conversion rate for product purchase. 1-5% is probably good for email signups.

A lot of people click through to pricing pages just to see what it is like. I do that, even when I know I won't be purchasing the product on that visit. Only signups and clicks on "Buy Now" are legit stats for conversion numbers.
