Is there anything preventing me from putting a CJ ad on the same site I have a CJ ad running? I imagine not, but I just wanted to double check.
As long as it is not contextual ad, you should be fine! Is it a static CJ ad or is it dynamically populating products based on the content of the web page? (sort of how AdSense is context-sensitive)
You mean Adsense ad running. Google's TOS states you can't run any other form of Contextual ads. If it's not a contextual service, then you can pretty much use it. ~G
You can put CJ ads on the same page with AdSense, I've use both for more than 2 years, and there's no problem.
