Facebook was designed to be a platform where people could chat and interact with one another, but now it’s more about putting ads in and tailoring it to brands and people promoting their material than anything else.
The ideal use of Facebook is to make use of the world’s largest collection of customer data. Every action a user performs is a piece of data for Facebook. Facebook’s ad targeting is amazingly effective. For example, I only see ads for advertising tools from those who run ads. Additionally, the Look Alike audiences are a useful tool. This is when a company sends Facebook its whole customer list, and FB generates a list of 2–10 million individuals who “like” your customers. They also collect information over time about everyone who interacts with your page and website, allowing you to target “warm” prospects.
