When will Facebook get data from other websites and applications?
Many websites and applications use Facebook services to make their content and advertisements more attractive and relevant. These services include:
- Social plugins, such as our 'Like' and 'Share' buttons, can make other websites more social and help you share content on Facebook;
- Facebook Login, which allows you to use your Facebook account to log in to another website or application;
- Facebook Analytics (Facebook Analytics) to help websites and applications better understand how people use their services;
- Facebook advertising and measurement tools that allow websites and applications to display Facebook advertisers' ads, run their own ads on Facebook or elsewhere, and understand the effectiveness of their ads.
When you visit a website or application that uses our services, we receive information even if you are not logged in or do not have a Facebook account at all. This is because other applications and websites do not know who is using Facebook.
This means that Facebook will collect data from many places, such as applications that allow you to log in with a Facebook account, allowing you to share articles on Facebook's news site and in other places.
It can be said that it is not easy to escape Facebook's coverage.
Bessel said that the information collected by Facebook includes the IP address of the user's computer, the type of browser used by the user when surfing the Internet, the system software (Android, macOS, Windows, iOS, etc.) running on the user's computer, and other data.
Bessel said that Facebook does not sell these data, but use them to meet user needs. Although it is true, but it can also use this data for ad targeting, in order to more accurately target users to sell goods, but also better Understand the user's network behavior.
Bessel explains: 'If you visit a lot of sports websites that use our services, you may see more sports-related stories in NewsFeed.'
This is also why sometimes Facebook ads will follow you.
Bessel's blog post does not provide any new information, but it is part of Facebook’s enhanced transparency plan. The company is working hard to explain to the government and users how the data it collects is shared.
