From my experience, huge traffic does not always mean huge clicks.
It depends on the topic, niche, and visitor type. For example, if your domain is about parking, do you think people who land on your page are going to click? They know what parking is all about, and they know those are just advertisements....So a domain like this may get lots of traffic, but I seriously doubt it will make anything much of parking, or anything at all for that matter.
Maybe you can reveal what subject your domain is about?
