You probably have a list of Facebook pages who's updates are important to you - whether it be local businesses who you regularly purchase from, industry pages of interest to you, or organisations which your family interact with frequently, businesses which you're a customer of that you like! Facebook has changed their algorithm, meaning fans see less of the posts published by business pages.
Facebook isn't your friend! They'll only show your posts from your Business Page if you pay for Facebook adverts. This is a cool way to increase engagement & get your page seen by more people, organically!
