What I don't get with any of this stuff is that it actually works. Maybe I'm weird, but every time I see that ads actually work and people actually buy stuff as a result, it's a shock to the system. Perhaps that's from enjoying a predominantly ad-free existence online, but I can't for the life of me think of a case where I've actually clicked on an ad, let alone completed a purchase.

I'm much more used to clicking on links that are organically ranked high in DDG or Google, when I am specifically looking to buy something. I have to admit, I barely make a handful of purchases per year, so perhaps I'm just totally disconnected from this whole topic.
