When it comes to advertising you see on Facebook, Google and so on, it's not really them deciding to target you, but the advertisers themselves. Their ad networks allow access to you and the ability to target people by interests. The fact that you were talking about whiskey before is more likely a coincidence.
Still, the fact that the advertiser managed to sell you this really expensive product, shows that their targeting can be used really well.
no way its coincidence.
I've heard about this happening to others too many times. I had NOT been searching for anything related to whiskey. no way its chance.
When you advertise, it's up to you to try and guess who are the people that might be interested in what you are advertising, so you don't advertise just to people who have searched for the specific term. So you try to guess and target the right people on other demographic data.
Yeah, I’ve studied marketing, I know.
