I worked for a healthcare recruitment company in a capital city with some large hospitals and a number of universities. I can't for the life of me understand why they chose to spend so much money on trying to track healthcare professionals online when they could just advertise it on-premise where they actually hang out.

We already know that “personalized ads” aren't much netter than context one: https://techcrunch.com/2019/05/31/targeted-ads-offer-little-...

I can't understand why every company want me offer “personalized” service. It never works, and if I can't manually set preferences, then it's not personalized (because “personalization” means exactly that).
