What about the advertisement with binoculars that says your green denim jacket doesn't really go with your eyes? Well, a recent marketing study (PDF) is saying that making a highly visible advertisement content aware is too much for consumers. It seems that to optimize clicks and purchases you should use a highly visible ad or a more diminutive ad that is content-aware, but not both. For marketers, this report talks about the consumer having this crazy notion of privacy and at some point they start to feel like you're crossing the line."
