It does not take long for a pre scheduled campaign to go wrong..
It's ok to schedule a post for being closed on the holidays but trying to manage social engagement with scheduled posts is the wrong approach.
To be successful at social media you need to be just as engaged as your are trying to engage. When you post the same format and content over and over it gets old and boring and that's not what excites your fan base.
Get to know your followers, what they like and how they like you, then create groups, affinity groups and start listening to what they are doing, participate and get to know them, this is how you build a loyal social media following.
You need to check your social media platforms daily, listen to what your customers and fans are saying and then respond. Create affinity groups and engage to better create loyal groups.
