I think Adsense is probably one of the worst ways to monetize a forum. Some of you have traffic levels that should not be leaving you in the hole every month. You need to look at some alternative forms of monetization. I know it is easy to throw up adsense or yahoo but that is rarely a way to make any money with a forum.

$1! so far..

It really depends on how you use it and for what niche you are using it. It can be great extra source of income for your forum.

If you can make 5000 euro extra per month by installing AdSense, why wouldn't you. Since that is possible if you have 100k+ uniques (per day) on your forum.

There are ofcourse better ways to make money with your forum, but AdSense can provide a solid extra source of income.

Yeah but we don't live in a bubble where you just ad adsense on top of something else. You might have other means of generating income or ways that don't harm the user experience or impact it in a different way.

By that logic, pop-ups and pop-unders also could generate extra revenue, but I would not advise most people to use those to monetize their forums.

hmmm, you could be making more :D

I think I made about $4-$5k last year from my biggest forums. It's a gaming forums (low PPC) with 300k posts and 10k members. I hope to be in Big-Boards within 6 months. I make most my income via subscriptions and selling points. I get about 2000-3000 uniques per day.
