Facebook shopping

The majority of time spent on mobile is in apps, and people spend the majority of that time in just a handful of apps, including Facebook and Instagram.1 For people, the mobile shopping experience is often difficult to navigate. Customers can experience slow load times and too many steps on the way to checkout. This is bad for people and bad for marketers.
On Facebook we’ve seen that people are coming to our platform not only to connect with friends and family but also with products and brands.
