So does that mean you can actually use any ads on the same page, as long as they have a different color?
This has been a rule for as long as I can remember. However, the other ad agencies may have their own issues with being placed on the same page as Google
What about image ads then? You cant really tell the difference (i see alot of arcades with adsense and fastclick image ads on the same page).
This is a problem. But on the bottom side you can see a link that say......... Google Ads or Other Site Ads
Not sure about the image ads. As long as you aren't hiding the Google link on them, then there is no mistaking that it's a Google Ad .
you can run 2 contextual ads on the same site, same page. i've confirmed this with Chitika and it is fine with both adsense and chitika. only thing to remember is that if you run adsense search box, you cannot use chitika search box. others may have their own rules
