Ever heard of p-value?
You find your sales per hour are down “significantly” for the last hour, and you find that 100 times over the last year.
How many times have you definitively been able to find out why?
My point is you will get so many false positives, some false negatives, and you’ll have zero forensics to make it actionable… why are you trying to do this, is it a gimmick to sell to other sellers?
If so, ok, go for it. You won’t get my subscription fee.
If not, why not focus on the actionable stuff:
- My ranking dropped
- Someone starting selling on the listing or Buy Box percentage went down
- My product is under hazmat or other ineligible status
