The nature of the Facebook Newsfeed should encourage you to pace your updates. When people are browsing Facebook, they see an up-to-the-minute list of their friends’ updates and shared content. Get your information in there from time to time instead of all at once so that you can reach the most people.
Make a calendar of what you’d like to post. Pay attention to holidays. Do you have any events or upcoming specials? Tools like HootSuite allow you to enter your posts at once and then will post your updates automatically on the days you specify.
Whatever you choose to do, check your Facebook Insights to see what performs the best. What kind of content generates the most engagement? What days and times are most successful? Use this information to adjust your social media schedule to really get the most out of it.
