So we keep doing ad-targeting and spending tons of money on campaigns, but where are we going with this? No one seems to care about the effectiveness of these ads, or if the algorithms really know which ads to serve. The ads industry is a giant industry following its own set of rules making loads of money. No one is to blame I guess. But if the goal is simply to make the metrics and KPIs look good, I think that kind of spending is missing the point. It also contradicts to how engineers try to optimize the speed/performance of everything to save cost. On one hand arguing over tiny little things over CPU cycles and memory usage to save infra cost, on the other hand spending crazy loads of money on ads. I don’t have a solution to all these. I guess I am just ranting.
