To the common question:
“I have been posting coupons to FB coupon groups for months. I haven’t had a single sale from this. What am I doing wrong?”
I have this response:
In general, stop doing things that don’t work. This will free your time and energy so that you can do other things that can work.
Two things at play here.
1: you need to find where your ideal audience is and they’re not on FB coupon groups. If your ideal audience is “people wanting to learn piano”, you need to present your course to those people in that place.
2: you might be asking for too much trying to get the sale so quick. I recommend you look into content marketing, where you build up trust using a steady stream of free content before asking for the sale.
