With the success of SnapChat, Facebook are going to trial posts that will disappear, you will have the choice of 1 hour to 7 days.
For us marketers this will be an interesting feature if rolled out to everyone. Allowing for sale and offer messages to only last for a certain amount of time. I’m unsure if the engagement of those posts will disappear as well.
Looking forward to testing this once it’s out. Facebook are rolling this out to mobile app users first.
