This would be against the AdSense TOS and could get both of you banned. I wouldn't take the chance. If you want to share the revenue from the same page, then just use a script that rotates through both of your IDs.
I don't see why it will. Isn't that exactly what DP does over here with revenue sharing? I personally get part of my earnings from a site where different client IDs are rotated, but that site has only 1 banner spot per page, so doesn't display multiple IDs at once.
You do need Google's permission to do this, otherwise it's against the TOS. Digital Point only displays the ads of one publisher on each page - those with sharp eyes will notice that the top right banner and link units in each thread belong to the same account.
It is a million dollar question. I see contradiction here: 1. The Google Adsense's TOS forbids it: https://www.google.com/adsense/static/en_US/LocalizedTerms2.html 2. However, a Google Adsense technical staff personnel says something else: http://groups.google.co.uk/group/adsense-help-misc/browse_thread/thread/fbfea071f2d3238/469186586562bfb5
hmmmm, controversial question.... they probably have that because they don't want webmasters to sneak in their adsense code into someone else's page lol
Even if you request permission, I would still be wary of doing it. I would do what nichevalue says and rotate the ads. One time load Account #1 ads, next time load Account #2 and the Account #1 the time after that.
Yes, it is allowed. But send them an email first to let them know about it. I personally emailed them long time ago regarding this issue and they said it is OK.
thanks for the info..just search this from big G. as im making an adrevenue script for building backlinks on my SEO site..
