Do you know if you want to have a chance to go viral on Instagram, you should post between 6PM-8:59PM. However, the prime best time to post is at 8PM.

I recommend you spread the image/video posts between Friday, Saturday and Wednesday for the best engagement. You don't have to post every day. Keep time zones in mind.

Aim for volumes around those times and keep it consistent for over 30 - 60 days following this pattern to be able to analyze results and gauge any success.
