A new infographic from media information company Vocus shows just how Facebook is growing as a marketing tool for businesses. It outlines the stats which suggest that, although the social networking site started out as a personal platform, it's a top resource for finding and engaging consumers. For example, Facebook fans are 79 per cent more likely to purchase your products. And with 50 per cent of businesses seeing a drop in marketing costs upon moving their brand onto Facebook, it seems to be a win:win formula.
