In 2014, Mark Zuckerberg, CEO of Facebook, said that the
main focus of the network is to become a "personalized newspaper for each
person." Therefore, Facebook is constantly learning about the behavior of
its users, seeking to empower them to come up with the definition of what
actions define whether content is interesting or not. The goal is to keep
visitors for longer on the social network, interacting with as many
publications as possible.
The “like” button, implemented in 2007 - three years after
the launch of the social network - was the first significant change in the
algorithm aimed at mapping the level of relevance of content to users. The
strategy developed until, in 2016, the reactions were launched, other buttons
that aim to go beyond the approval of a publication: they seek to measure the
engagement it generates, receiving positive and negative feedback.
Two of the aspects that guide this analysis are:
1. Origin of the publication
By 2015, after concluding that its users were very
concerned about losing updates from their closest friends through news feed
information, Facebook's algorithm allowed them to choose which pages or people
they'd like to see the updates first. Before that there were only filters for
what people did not want to see, with the option to hide posts and unfollow.
Relevance of content and engagement with other users or pages was measured by
tastings, shares and comments. At this point, the News Feed Preferences were
launched to empower them in this choice.
2. Relevance of the publication
Based on the history of interactions, the Facebook
algorithm can predict when a publication will be tanned, clicked, commented or
marked as spam. The combination of variables creates the relevance score, which
organizes the order in which the posts will appear for each user. The first
that appears will therefore be the most capable of engaging at that moment.
This calculation is always fed by positive and negative feedbacks. The same
logic is used with Facebook Ads. If ads are expected to improve users' social
network experience, the relevance score contributes to the identification of
the target audience for companies that use that attraction strategy.
The Instagram Feed Algorithm
By the year 2014, Instagram had no algorithm that
individually monitors users' activities for suggestion of photos in its
"explore" tab. There, the most popular publications were shown among
all users, without any specific guidance. In addition, the timeline showed the
publications in chronological order, regardless of their relevancy. However,
when acquired by Facebook, Instagram started to focus on improving the user
experience, since it was estimated that they did not see 70% of the photos of
their feeds in their visits to the social network. From the new algorithm, the
order of publications in the Instagram feed is defined by the following
factors:
- Number
of likes and comments to measure engagement;
- Level
of user interaction of the post source;
- Publication
time, so the social network does not lose the chronological characteristic of
the visualization;
- To
whom the user sends direct messages and what type of content shared with these
people.
