I just post between 6:00 AM and 7:00 AM in my local time zone (US East Coast) Mondays and Fridays.
Been less than a month, my story has been viewed 220 times, my first chapter has 31 views, second chapter 17, and the rest settling around 4 - 7. Got one comment, one like.
That's better than I expected, because I am juggling some themes and subjects that aren't everyone's cup of tea, I open with a dream sequence, and the first six chapters are slow buildup and character dynamics/investment.
And I post at that time because I'm a morning person and the kids aren't up yet
Granted I don't have experience to know if that's "good" on a relative scale, all variables considered, but I know every time I post I get more views. That works for me
