From experience and talking to other webmasters, 1% CTR is considered "good". Especially if you have a lot of visitors and return visits. Return visitors rarely click on ads, that's evident with forums. Forums have the worst CTR I have ever seen in the history of online advertising. And I have a lot of forums that I run. A few with 2 million + posts.
