Don’t pay attention to what others say when it comes to the best time to post on YOUR social media account.
Take the time to acquire the information & research of your own followers & their patterns & work off those peak times.
You’ll see a much high engagement rate & follower growth.
A majority of my followers are on from 12am-3am. So I schedule posts for that time period.
If you look at what other people say; you’ll hear them say that you should never post at that time..
Come to your own conclusions.
