Another question is when we place PPC ads it show the destination url and display url. I see some people put direct link to destination url and put different domain name. So what is the point we buy domain? Since i can just choose any domain to be appear and directlink is totally different domain? Sorry quite new to this really need some help.
Last question. Is when i bid $1 for CPC and than suddenly i drop to $0.10 will adwords or adcenter hate that since it is so much different? Please help me if you know the answer. Thanks in advance!
