Hi, I created 1 channel in adsense on the header of my website, I notice that it displays about a range of 10-15 different advertisements for all of my pages. Every time I load the site, it is the same advertisement. My question is if I create another channel, and put it on the right side of my website, is that going to show the same advertisement as the header, so I end up having two advertisment of the same thing on the same page? Also, how to increase the dynamic advertisment (from 10-15 to more advertisment) on display so that it change more frequently each time I load the page?
Creating channel for different ads places can help, because at adwords advertiser can pick place where at website he want to advertise.
I have noticed sometime they show the same advertisers but most of the time they are different. It depends on the number of available advertisers. But, it is always the highest bid advertisers on the first ad unit on the page.
thanks, and how to increase the available advertisers? now, it is always those 10-15 advertisers, how can I increase that?
