I've tried Google Adwords, nothing but a waste of money for me. Got maybe one interior detail from it over 4 months running a couple different ads and wasted hundreds of $. I've heard some people have good luck with it, but not me in my area. There's also so much to learn about keywords and what not, it was just not worth it for me.
I had a Facebook ad running, got a bunch of people to like my page, but no sales from them even after offering discounts for anyone that likes the page.
Maybe other people have had better luck, but not me.
