Hi, I didnt know where to put this topic so hopefully it is okay here.

I have a forum and I would really like to know more about how much I can generate monthly from Google Adsense. I dont understand most of the jargon.

It has 3800 members, here are some average statistics:

Page views (are these impressions?): 500,000
Hits: 4,000,000
Unique: 20,000

Now Ive played about with the calculators you can find online, so I entered:
Impressions: 500,000
Click through rate: 0.5%
Cost per a click: $0.05

...and it came out with $1,250 a day, hmm, I must be clearly doing something wrong. :D Thats a lot of money.

Im not looking for an accurate answer, just a range, even if its a fairly big range I want to understand it better and know what I can make off my forum (Im not wanting to test it as I like to plan it a lot more than that, Im curious really).

Its IPB forum software, I would place Google Adsense at the header and footer so visibly in reach.

Thanks alot,
Nick.
