Has anyone had any good/bad experiences with Facebook ads?

[John W]

I have never placed Facebook ads but from the perspective of a prospect, I never saw a single ad that was remotely relevant. Some were frankly surreal or creepy. Over the years Facebook has served me ads that imply that it has thought variously that...

1) I am gay.
2) I am Hindu.
3) I am a jock.
4) I live in Birmingham, U.K. and can afford £457 love-seats.

All of these are inaccurate.

One of my friends started dating an engineer and was promptly bombarded by adverts for wedding rings, Victoria's secret and technology schools. She was highly disturbed out about this.

Unless someone can come along with actual nuts-and-bolts money answers that suggest my experience is atypical I would suggest that you not spend a significant amount of money.
