Lets say there was a website with 50,000 views a day compared to a forum with 50,000 views a day. Both are on the same subject. Using ads, which one is more likely to make more?
Website, clearly. With forums you are getting a lot of repeat visitors who probably would not pay attention to the ads.
Website because you would be continually attracting new visitors. I would guess forum users are blind to ads as mentioned above.
I think website is more likely to make more. Since forum people are more oriented to forum than clicking ads.
I agree, majority of the CPM networks don't allow forums unless it is attached to a website, you can guess the reason.
I voted for website, because people get used to the place they visit everyday. Website is different from forum at this point)
