What you do on other websites and apps which use Facebook’s service and technology will be used to track and according to your activities ads will be displayed.
Marketers can now select languages, “ethnic affinity and various life events such as people who have recently moved to a particular place or got a new job.
Advertisers who want to target the newly engaged can narrow that down to engagements within one year or within three months. There are even options to target baby boomers, video game console players, early or late adopters of technology, fans of specific sports teams or people who go on cruises.
