We have a potential client who wants us to display ads on our site via the doubleclick digital ad server (http://ad.doubleclick.net with parameters). Does this go against the Google Adsense TOS since they own doubleclick, I believe? The client ad is not part of the Google inventory. I cannot find anything in the TOS about this but want to err, of course, on the side of caution.
Thank you in advance.
