Facebook has launched a new update that allows you to add a button to your cover image and drive traffic to a video, website, app or your e-commerce store.
Go to your Page’s cover photo and click Create Call-to-Action and add a button to get people to take an action from your page.
Setup - Choose what do you want to make people do when they click the button. Give the setup manager the links where you want the traffic to move.
Destination (iOS) - Choose where to send these people when they tap the button on an iPhone or iPad.
Choose your call to action and the destination URL that you want to link to. Facebook will automatically choose the best destination based on your specified web address, but you can edit these suggested destinations and click Create.
Stats and Numbers:
On the right side panel, under "This Week" stats, you'll find a new addition which are the stats of your "Call-to-Action" button.
