Zuckerberg smiles: How much does a like cost?

It's no secret that Facebook is making money for which we can only dream of.

However, it's worth asking what Facebook earns so much money, except for ads.

The answer may be a little scary: from our personal information. In other words, what we give for free, they get millions of them. In fact, users in the social network world are money machines, even when they do not buy anything. The reason for this is that social networks are an extremely important and comprehensive tool for marketing research.

Every time you click "like", "share", join a fan page, or even add a new friend, you create a new set of statistics that major corporations offer big money to get it.

Here are the exact values ​​of your profile:

- Only your app is worth about $ 81 - Each of your friends in the profile is worth about 0.62 cents - Each of your "like" has a value of about 0.03 cents

On average, each profile is worth $ 1,800, and a serious business or site group worth $ 3.1 million, Azra reports.

Seeing and tracking Facebook's growth over the last three years, it is estimated that they have collected 2.11 billion of information they can sell. In this way, Facebook earns about $ 1.2 million a day from its users' free work, creating what the Wall Street Journal calls "the greatest unpaid workforce in human history."
