I have a website that allow people to create an accounts and add listings to the website. Kind of like a recipes site where people can submit different recipes. My plan is for each recipe page, I plan to place two of my adsense add there and allow the person submitting the recipe to place 2 of his/her adsense ads.

So eventually as more and more people add recipes and their adsense adds, there will be a number of different pages with different adsense accounts.

My question is if this is legal from the stand point of Google.

Thank you for you help.

According to Adsense TOS, the most ad units you can have on any single page at a given time is Three. But this does not include other ads like link units or referrals

So can I have ads from two different accounts on the same page. One account will be from me and the account will be from the person who added the listing that created that page.

I know you can have 2 accounts on the same page, as I have seen numerous other sites do it for extended periods of time. I don't think that you can have 2 ads from each account though, as that would be a total of 4 ads, and as stated above you can only have 3. Unless 1 of those is a referral ad or something like that.

Yes, it is allowed to have more than one Adsense publisher's ads on the same page. No worry.

Thank you everyone for your responses. I feel a little better now knowing that I can allow people to put their adsense ads on my website pages.

My next question is. Is there any risk to doing this in terms of Google banning my account and all the other people's adsense account should one account violate Google's TOS.
