I’ve been using TribalFusion with my most prized site, ZuneBoards. I’ve been making a lot more money with CPM ads than CPC ads (CTR sucks on forums!). I turned $300 a month into $1,000 a month, which is pretty good in my opinion. However, I couldn’t help but notice my TribalFusion CPM has been slowly going down and down. At one point I was making $60 a day… now? Only $25-$30 a day. I started experimenting with ADSDAQ and I’ve been seeing some good results. I’ll update later on this subject.
