I promote my books
seven days a week.
Sunday is a huge eBook buying day.
I always promote on Sundays.
But I’m also aware
that Sunday is a religious day
for many of my readers
in the USA.
So I wait to promote.
I don’t promote early in the morning.
I promote around 3 pm EST or later.
It doesn’t make a big difference
in sales
yet it makes those readers happy.
Consider timing
when promoting.
