I guess its a stupid question to ask, but I really confuse at this time, I was doing some experiment for my non-english blog, and sometime the adsense ads doesnt show's so I'm looking for other good PPC like adbrite and bidvertiser, and what I want to ask is... Is it okay if I use adsense and adbrite/bidvertiser or other ppc in a same site?
Imranzia is right - it is ok. Adsense terms say that you can use other PPC ads on your site as long as they cannot be confused for Adsense ads. Adsense ads say "Ads by Google" on them, and adbrite/bidvertiser do not - so it is ok.
okay I got some news, it is okay to use adsense with other ppc, as long the other ppc ads have different theme.
