“It’s generally recommended to post at least once per day, and no more than 3 times per day, on Instagram.
I’ve found similar times of day to Facebook effective: my Iconosquare stats showed that 8pm was my best time, closely followed by 6am. Remember I’m on the West coast, so that’d be 9am and 11pm Eastern time.
Instagram is currently my second favorite platform, and I post six times a week.”
