I had the same problem. My max bid was $0.50, but then it charged me $0.87 for a single click. I contacted teh support, and they were very helpful telling me that I had set incremental bids for countries. I had set the incremental bid for US to 100%, thinking that I was choosing to receive all visitors from US . The point of the incremental bid is that, in general you set a default bid, however, for countries where you think competition is higher, you set a percentage of the increase on the bid based on the default bid, so that it puts you ad at a higher position. Hope it helped.
So is there any way to insure traffic exclusively from the United States without having your bid increase?
1. Probably worth starting a new thread for a new question 2. I'm new to AC so not sure, but ring them. They have good support
so should I create another campaign for that ? can you show me a real example...maybe a tutorial or something please
