After that i got an idea that i can do this for my another client too. so i have opened that account and have gone to "Edit Campaign Setting". But i didn't see that "Content Bid" check box. Have anyone seen like this?
Sorry i have Mentioned that as Campaigns. The Options differs between each Account
After that i have checked all my clients. 20% of the clients are not having this feature to be enabled. Anyone knows the Answer? Thanks
