I don't get any advertisements on my Facebook wall.
That said, I had a better response to comments about my book in Google+, simply because of the way Google+ works. Instead of simply having friends and family and people who have some connection with as part of your circle of contacts, with Google+ you generate circles based on common interests. So I have a number of people interested in publishing and promotion, as well as a number of writer, editors, readers, and so on in my circles. Seems like a more targeted approach.
