Facebook is one of the most popular social media platforms in the world, with more than 2.3 billion users. There are billions of eyes constantly scrolling though posts, videos, photos, status updates, and yes, advertisements.

When it comes to advertising, there is no company in the world that has more information about its users than Facebook. It includes much more than just your age, gender, alma mater, and interests. While those things are valuable for marketing purposes, Facebook also knows which websites you visit, how often you visit them, how much time you spend doing various things online, and what you purchase. From a business marketing standpoint, this information is absolute gold.
