What is a good click through rate?
All the responses so far haven't actually answered the question, which is what is a GOOD click through rate, not what IS a click through rate. We don't need the definition of a CTR to answer the question, as the OP already knows that.
A good one varies wildly according to your source of traffic. Organic, search traffic will bring a higher CTR than random hits. Further, it also depends on what the visitor is clicking on (link? banner? text ad?).
