The optimal posting hours on Instagram to get more engagement are generally between 9 AM and 11 AM and 6 PM and 8 PM when people are most likely online. The weekdays, particularly Tuesday to Thursday, tend to have higher performance than the weekends. But really, the perfect time varies based on your audience's activities, geographic locations, and niches. Use Instagram Insights to find out when your followers are online. Trying various posting hours and measuring engagement (likes, comments, shares) will assist in fine-tuning your posting schedule. Alongside timely posting, maintaining a regular posting habit with compelling content is equally important for increasing reach and engagement.
