If you scroll down your Facebook news feed, you’ll most probably see a post which says Sponsored or Suggested Post on it. Or if you’re on a desktop computer, you’ll see ads on the right side of your screen. You’ll even see in-stream video ads while you’re watching a video on Facebook. Also, you’ll see ads or sponsored messages on Facebook Messenger, Instagram, and the Audience Network. These adverts are known as Facebook ads. Individuals, small businesses, and large corporations pay Facebook billions of dollars a year to show their ads to Facebook users. And it’s not surprising because compared to other platforms, Facebook gives their advertisers the best bang for their buck.
