There is a simple way to know with some accuracy what Facebook knows about you.
Leaving the smoke of speculation and conspiracy, but also simple sociologisms.
For some time the section on "Preferences at advertising" is in fact easier to navigate and customize, for example, to get rid of ads from sources considered to be very little appropriate.
But how many are aware of this possibility and all who care to treat the parameters according to which the social network we bundles and shows an ad instead of another?
First, an introduction.
When a company creates an ad choose the type of audience you want to reach, and if the user falls in some respects in that target, the target ends.
Those aspects are precisely defined by preferences, in turn deduced from a number of activities carried out on the platform.
From the information I've shared the Pages you fans and interact with them more often to the advertisements on which you click, apps or sites that use frequent and information produced by the data provider and by the same advertisers.
In short, (almost) everything you do inside but also outside Facebook.
That almost everything ends So get organized in that vast section of which few are aware.
Analyze it well, virgin, that is as composed from the Facebook web and never changed by the individual, returns took a picture quite clear how it is sold to the advertising.
He spoke to the New York Times, giving the subject a purely political slant.
Putting that in light of the fact that even though we consider ourselves very discreet in our posts about politics, this alleged discretion not prevent to label platform.
On the precision or not, we will see later.
To give air to these skeletons in the closet must click on facebook.com/ads/preferences be logged.
So the tourist arrives on a page organized by themes, each expandable, containing a number of topics, ie topics, subjects, companies, sports teams, educational backgrounds, musical band, characters, reference newspapers, travel and places d ' interest and much more.
There is therefore your life in list format.
These lists are in fact customizable.
Each element can be removed and that other added.
But, as I said, it is unlikely that many have cognizance of this possibility.
For the vast majority of users did Facebook to draw quell'identikit.
It is indeed the basic mechanism through which those dollars 11,86 bill of advertising per user on average, $ 6.2 billion in the last quarter with a jump of 63% year over year.
From that tag, so to speak, originates much of that flow.
Facebook gets to determine those preferences also indirectly.
That it is deducting from common interests more likely interests.
It is probably the passage that puts tags senseless and complicates a little 'things.
In direct tests we performed many pieces actually come back, others much less, there were some even forgotten them.
The Food and Drink section passes from steak to lard the mozzarella up to pistachio, barley and yarrow.
But the components are 55 and it would eliminate perhaps 6 or 7.
Not a bad percentage.
Commerce and industry is richer, it has 123 preferences.
It goes Vueling and Alitalia (where in fact we often embark) to TripAdvisor through Netflix, Caterpillar transmission, Twitter, web radio, press freedom.
Let's say that in this case would we do without at least twenty.
But basically it is difficult to say, because we interact daily with an amount of content even from foreign profiles and pages on Facebook logic probably fall into certain topics.
Family and relationships, Fitness and Wellness, shopping and fashion have fewer preferences.
Very rich are the information collected under the hats People, News and Entertainment (249 items), Education & Hobbies and activities (in absolute section where profiling appears most lacking: we arrogate among other passions for the bunga bunga and a brand of cars that do not love too).
But they are Lifestyle and culture, and news and entertainment to constitute the identikit heart.
In the first case, apart from Lutheranism, the Liberal Party of Canada and the Chinese language or the US Republican, the profile looks quite sensible.
In the second matching it is much precisely because it is the 'easiest area to be "read" and so to speak decipher, since it brings together artists, movies, magazines, film and music genres, bands, TV channels, by comics , many of which end up at the People item.
In short, get lost in the preferences and labels that Facebook has saddled us during our "social life" is an exercise doubly helpful.
On the one hand it provides us with a solid platform of what it means profiling and the quantity of information that every day we give in to the company, allowing them to put them handsomely for sale.
On the other reminds us that there are instruments to limit this invasion, and that even the most powerful platform available continues to make the big mistakes.
Which, in a future perspective, portends room for improvement to say the least disturbing.
