Facebook – the social network that started in a Harvard dorm room 15 years ago – has evolved into a media and advertising giant. It’s helped create a new age of precise consumer insights. With over 2 billion users worldwide, Facebook can offer granular data about each and every one of them to advertisers – not just demographics but the very narrowly defined interests, conversations and interactions they have on the platform. Advertisers try to leverage all that information into online purchases by directly targeting consumers with messages meant to stand out as they scroll through a newsfeed.
