is there any tool to estimate/calculate adsense earning of a site

we have a forum and we didn't started to use AdSense on it Still i want to if it worth more than getting an sponsor

 

Dont think so as I think there are too many factors such as reputation, new visitors/old members/ placement/ origin of traffic, etc.

Post some stats on here and I am sure people can give you an idea.

 

add adnsense on your forum & manage seperate earning channel on a adsense control panal, this will let you know about the earnings you get from your forum..thnks!

 

Depends on your niche + traffic. Even that will give you a pretty rough estimate. Best way is to just try... other than that it's all just guessing.

 

our Forum , receiving 3000 UV Daily Traffic 80% From search engine and 20% from links in other website and also we Got Strong PR 6

 

Well, what about the niche?

 

Normally, forums have very less CTR. But, if your forum get CPM ads, then it might be useful.

 

you can caluculate it only basis of ctr and cpm ,
even u think ctr is same for all websites then what about cpc and ecpm they wary for niche to niche and site to site

 

May be you can earn anything between $ 5 - $ 15 , you can surely try it for a day

 

It seems that real life sponsors pay more than Adsense, but its very difficult to fill your page with ads you sold.

 

Getting real life sponsors for a blog/forum is not easy , or rather close to impossible

 

if you'll make your forums inside the website and you'll put ads on website margins [not on forums] you'll get good CPM.
