I just started my store about 1.5 months ago. I got a campaign going and have been letting it run. Slowly, sales are growing (8-10 / day), which is great. Suddenly, sales have drastically decreased. 2 on the 24th, 5 on the 25th, 1 today.
I’m using the same campaign (increased budget from $30 to $40 per day), I search keywords on Amazon, and my item is the top product. I haven’t touched any settings, but suddenly, sales slowed down drastically.
