线上广告十五问 (15 Questions About Online Advertising)

This is not really a book, but rather just a screed. I ask 15 questions about online advertising that nobody ever dares to ask.The real question of course is: Does online advertising work?The right question to ask would be: for whom does online advertising work?Do banner ads, what we once called interactive advertising and now call display ads because nobody clicks on them, and much less "interacts" with them, work for publishers? Do they work for advertisers? Or do they just work for the middlemen based in Silicon Valley?
