How to find your own best time
- Start with two or three of the slots above, in your audience's time zone.
- Post at each for two to three weeks with similar content.
- Compare reach or views after 48 hours in your analytics, and keep the winner.
Your analytics also show when your followers are online: Instagram Insights (Most active times), TikTok Studio (Followers tab) and YouTube Studio (When your viewers are on YouTube). Those beat any average.
