Best ads on Facebook are brand ads and these work on your subconscious. Unlike Google Search that shows immediate intent, you don’t have an immediate need while browsing FB. Sure there’s the occasional impulse buy for some iPhone case or jewelry you don’t need, but the big companies don’t care for your clicks. E.g. what are the default beverages people buy when organizing an event? Beer and Coke and it’s not a coincidence or because there aren’t better choices.

In other words, as long as you look at ads, your buying choices get influenced by them, so you are generating revenue for pay-per-view ads, even if you never clicked on one.

I don’t mind seeing ads though, as long as they are tasteful. What I mind is the tracking and in that regard Facebook is among the worst.
