Amazon credits a sale to your ad up to 7 days after the click. Every fresh report understates sales — the trap behind most panic bid cuts, explained.

Amazon credits a sale to your ad for up to 7 days after the click — a buyer who clicks Monday and buys Friday lands in Monday's numbers, on Friday. So the most recent days of every report always show spend that's complete against sales that aren't. Judging campaigns on this week's data is the single most common cause of panic bid cuts that were never needed.

## FAQ

Q: Is the attribution window always 7 days?
A: Sponsored Products uses 7-day attribution; Sponsored Brands and Display differ (14 days on some views). The practical rule holds regardless: recent days undercount sales.

Q: Does the lag affect organic sales numbers too?
A: No — order reports record purchases when they happen. Only the credit of a sale to an ad lags. That's why ad dashboards and order dashboards disagree about "today".

Q: How should I set date ranges for decisions?
A: Windows ending 7+ days ago for judgement (e.g., a 30-day window ending last week). Fresh windows for spend and delivery monitoring only, never for pausing keywords.
