I know the chances goes to 0% if it's for authentic, period correct, women's laderhozen. If it's a book about data science, then there's a good chance I'll click through. Of course, this is all anecdotal, especially since I always had ad block on back in the days before targeted ads, and have never really been subjected to ads that's weren't somehow related to me or the immediate context. If you've ever been around a child, you know how much targeted ads can work. They want the toys that they see. Showing them ads of Bentleys won't result in any sales.

I would recommend talking to someone that does A/B testing.
