Here is the relevant bit from the T&C. From what I gather, it would be okay to simply stick the link unit in div and disable overflow to hide the 'google ads' sign. I have a hard time believing that is not against the rules, but I figure I should ask anyway, since I want to use it beneath my nav bar, and I want to be absolutely crystal clear and abiding so I don't get banned. Another small question... My current layout for a website I am working on is set up with 3 advertisements. One leaderboard on the top right (728x90), the wider link unit size beneath the nav bar, and a wide skyscraper I think (160x600 is the size); Now my question about ad placement is I currently have the wide skyscraper in the leftmost position directly beneath the navbar. Is this problematic being directly in the viewer hotspot? I'm obviously aiming for most clicks, and that would be a prime location IMO, but I don't see many other sites doing that. Is something wrong with it? Thank you so much!
you may want to do further research on that ad placement. Either that, or shoot them a customer service message.
