I've noticed this mostly on Google properties, YouTube in particular. Most of my YouTube viewing is done on my TV through an Amazon FireTV device, so I see a lot of ads. Now, Google knows me very well and should be able to target me with super effective and compelling advertisements. Yet, I get tons of ads for products that I would never, ever purchase. Things like women's beauty products (not a woman), alcohol (never drink), trucks (not interested). While things that I would be interested in are never seen; science fiction movies, technology news, etc. I really don't see how Google (or any other ad company) are successful at all. I'm guessing they are just spewing ads to everyone on the planet and hoping that some stick. It feels like the "male enhancement" emails have the exact same process and probably work just as well.
