I recently had one of my ad campaigns disabled right after I put an amazon banner ad at the top of my site. I know sites that mainly redirect to other sites aren't allowed to be advertised with adwords, but I thought having one banner ad was okay. Do you think the fact that I had it at the top of the page, and not at the bottom, was the problem? Or are you not allowed to have amazon links or banners anywhere on a site advertised with adwords?
I think banner ads is too big to be used with adwords, especially on the top of the page, instead you can insert some links related to any words in your contents.
