While each audience is unique, having a rule of thumb can be extremely helpful when you’re first starting out. Sprout Social recently published the results of their “Best Times to Post on Social Media: 2018 Industry Research”, a report which includes preferred time slots for the big 4 — Facebook, Instagram, Twitter, and LinkedIn.

Using this data as a guide empowers marketers with the best opportunities to maximize personalized consumer engagement.
