Here my progress so far:
I can't tell whether these stats are good. This is my first teepspring campaign.
0 sales thus far. It hasn't even been a full day yet, so maybe I need to wait longer?
I have the ad set at $30/day,
How much longer should I wait before determining whether this is a failure, and cancel the ad?
My design is targeting a very specific niche. It's not a trend-based design.
