All depends on the content. I had a mobile media forum. With 400 daily uniques i was making $11 (on average) a day.
Well forum really not get that much of money from adsense with 900 unique per day. Income depends on the content of the site.... I have 1 site which is content site earning $18 a day from 500 uniqe a day.
Clicksor for example. Start a forum offering free (something). Start a new thread with the topic "Get free something here". In the body say: Download it here -link- Clicksor would eventually highlight the "download" keyword. Then you just lock the thread, lock the keyword in clicksor tools and delete the link. 90% of the people visiting that thread, looking for free something would click on "Download" Similar things could be done using adsense (on a smaller scale). Its how you implement the ads.
Taking a quick look at your forum, the first thing I would do is switch to vBulletin and cut down on the number of forums you have. Start with fewer forums that have more activity and then add more as activity increases. Right now it looks like lots of semi-inactive forums. Nobody wants to partake in an inactive community. I'm not saying that creating a successful forum is easy. God knows it is not. It takes a LOT of hard work. But once you hit that tipping point, they can become highly lucrative.
Thanks. I'm sure it will become more active. Was hacked a while back had 1000+ members within 3 months. I'm sure it will get up there soon enough thanks for your remarks again guys. The Gun Owner don't you own lws?
$10.00 a day s possible with one site with around 200 page impressions but you have to make sure your CTR is good as well.
Try to make your website to comes in google no. 1 atleast 25 keywords then you will get lots of money through them.
