Yeah, like Jen said, there's usually no good ratio when it comes to views/sales. I had sales on days when I had views under 30/day too.
I notice on days I post a lot in teams, my views sky rocket, which is fine and I will gladly accept. But I know that I probably won't get any sales from it since I'm not really not marketing my items, just helping out.
But on promotion days, I'm hoping those higher views will bring me in sales.
