Nobody lowers a bid because the data told them to
They lower it because the number looked scary on a Tuesday
Check your data window before you move a number
Amazon attributes sales to the click date
So the last few days of any report are still filling in
Cut a bid on a two day snapshot
You are punishing keywords for orders
That have not been reported yet
Sample size beats the metric on the screen
A keyword with a handful of clicks does not have a conversion rate
It has noise
Then confirm it is a bid problem at all
Amazon PPC has more failure points than the bid
A campaign that burns through budget by noon is not underperforming
It is capped, and lowering the bid hurts rank while spend stays flat
Move in small increments
Change one variable at a time
Log every edit with the date
Bids are the last lever you pull
Everything upstream tells you whether to pull it at all
