I realize Shopzilla is contextual however; the Shopzilla Publisher BETA features text next to an image and a large Shopzilla logo at the top. No one would confuse it with the Adsense ads. Would this still violate TOS for Adsense?
I suggest to send question to adsense staff before placing other ads. Let them confirm or deny this idea
From official Shopzilla Publisher Blog: "Compatibility with Google AdSense We've had some questions lately about whether the Shopzilla Publisher Program can be used alongside of Google AdSense, and the answer is YES! Since Shopzilla's ads are not contextual, you won't violate your agreement with Google."
