The secret of an effective advertising campaign is to create content that will attract attention of exactly those people whom we want to reach - i.e. target group. Thanks to analysis and collection of data on users (which in 2016 was 1.65 billion, or a quarter of the Earth's inhabitants!), Facebook allows for very precise match of displayed ads to the right users. We are able to analyze not only the information posted on by profiles' holders, but also activity of recipients, their place of residence, education, visited places, musical preferences, friendships, and much more. All this so that the content displayed would be the most personalized and fit the users' tastes. This shows how strong is the tool in our hands which, if used properly, will bring great results to your brand!
