I believe the effectiveness of Facebook advertising in general depends totally on what you're trying to sell. We tried it briefly for about a three-month stint and didn't get a single conversion. We targeted engaged women in the 20-30 age bracket within this region for wedding photography. It ran about $250/mo but didn't net one single inquiry whereas our Google ads account for about 40% of all inquiries for our services at half the price.
