There are other way, but keep on to the one you know best, as much as the money is come, best of luck.
I guess the traffic I get, Banner ads would give more profit? Nearly 1000 uniques a day and around 7000 page views. Daily, 25-35 members and nearly 400-800 posts. But too sad income. Getting around 22-30 clicks a day.
In my extremely limited experience, the amount you get from a click can vary all over the place. One day you will get 3 cents, the next 24 cents, the next less, the next more. Just keep on developing and promoting the site, and get rid of anything that might get you banned. You are doing well.
