After peak season, short-term data windows and 30-day averages mislead you because buyer intent has dropped. Track CPC, ROAS, and ACOS daily instead, adjusting bids each day while the market is low-intent. You need current signals, not stale noise.
99% of the time, you never want to make optimizations based on 48 hours, 72 hours worth of data, especially on Amazon PPC. But now that selling season is over, you want to track your cost per click, your ROAS, your ACOS, basically like a hawk day to day. Because if you start making adjustments based on the last 30 days, you are going ahead and working with the worst type of data. Consumer intent is basically gone. Selling season is basically over. So now you want to watch your cost per click. You wanna watch your bid adjustments. You wanna watch your ACOS at a day-by-day basis.
