I was wondering if Google allows publishers to float adsense ads, in particular to use it as the DEFAULT AD SETTING in Clicksor (so AdSense ads will be shown when Clicksor doesn't have enough ads)? Also, I was confused as to the number of adsense ads allowed to be shown on a single webpage, as some says 3 and some other says 4.. This is because when you are using adsense as the default ad setting on other ad network/s, google doesn't automatically take out any adsense spots even if it exceeds the limit of allowed spots.. THanks heaps in advance.. Cheers
