Should your business use Google AdWords or facebook Ads? Depends on your goal. If you want to get people straight to your website to buy your products, use Google AdWords. If, on the other hand, you want to build an email mailing list (with a free offer such as an e-book) or build brand awareness, use Facebook. Why? People use google to search for things they need, such as a chiropractor in Brooklyn, or stylist in Berlin, whereas people go to facebook to socialize and so are more likely to react to a soft offer.
