I'm deeply involved in digital advertising and I don't even understand what you're trying to say, so maybe you could rephrase? At the very least, the "common wisdom" number is suspect (a random lampshade). I've measured bot traffic as high as 98% from quality news sites like the OCRegister.com
I want to say that most online ads people don't get that "you can be losing 30% of your ad spending, but things can be dramatically worse and you will not know it no matter how hard you try"
