I get around 15,000 total visits out of those about 8000 are uniques a month. One of them is a forum, so the page view is high for that one. How much should I be making with adsense with those figures? The sites are the three in my sig. Thanks.
Difficult to say. Forums are notorious for thei low CTR. However, other factors like pacement, topic of the forum, etc would determine how much you might make.
