Its a good question - think about it, not only does google not allow you to disclose information about your adsense account, like Clicks, Page CTR and eCPM, they also won't tell you what revenue they share with you. So why?, well its a licence to rip you off that why, by hiding the information they stop you comparing with other people and knowing if you are getting a fair deal.

Knowlege is power and for all we know every cent google give us for our clicks could net them 50 cents or more. Having seen all my numbers stay the same but revenue drop to less than half, whats the answer - smartpricing, so my clicks are worth less than before, but is the advertser paying less, well only google know and they aren't telling - something to hide maybe.

IMO google is turning into the new microsoft - don't be evil - try don't be dishonest and sneaky google

How can they tell how much the clicks are worth anyway (the theory behind smartpricing) where do they get the info from - google analytics maybe, but how many companies implement it fully, do they want google to know how much they make, when I implemented it I didn't bother with the revenue part - I didn't have the data as all my 'sales' are subject to conversion and possible cancelations - but from google data it would seem like click throughs to my site make no money. There are other factors, not everyone buys first visit, but they come back later maybe and then may even become a regular customer, mabe spending 1000's over the course of a year - all from one click - or maybe not - how do google know, or is it an excuse to drop your adsense revenue and keep more for themselves - only google know - and they ain't saying

I think they don't tell us how much they share with us because they don't share a fixed amount. The share we get is probably calculated by an algorithm that takes many factors into account and changes click by click.

All i know is that each month a bunch of money is paid into my bank account and that's good enough for me.

Mark, besides that, you can't find a decent ads publishing service out there that can give you anything close to Google (service wise), that's why you have to live with it.

If I found any other decent service that can perform a little close to G Adsense, I would've left them long time ago.

Tony - I know, for google its a sellers market

PPC network is such a market where people will go to any extend to make few extra cents. Already they are facing all sorts of click frauds and other law suits. I guess it is for the benefit of the market to keep the vital information secret, google is probably right about that.

They keep the information secret simply because they have to, as alemcherry pointed out.

The problem with revealing of information is that it leads to a lot of reverse engineering and tricks of that nature. If you give a scumbag enough rope, he'll eventually try to tie it around someone else's throat. This is what the search engines have taught us, and Adsense to some extent teaches us the same thing.

Personally, I don't have a problem with that. If I did, I'd use another ad company. They are out there (check out www.adbility.com for a whole bunch of them). The problem is that Google has the dominant publisher revenue generator right now, so it's assumed that they're the highest-paying.

It really isn't as big of a seller's market as you guys seem to think it is. There are other options.

they could tell you what percentage of the revenue they share, you can't reverse engineer that, how many other biz modles can get away with saying - we will pay you commission, but we are not telling you how much
