How long is Amazon's lookback window from the point of conversion, used in reporting ad-attributed metrics?

Amazon DSP's standard lookback window for attributing conversions to ad impressions and clicks is 14 days. This means that if a customer sees or clicks an ad and then converts within 14 days, that conversion will be attributed to the ad. While other lookback windows (7, 30, or 60 days) might be available for specific campaign types or custom settings, 14 days is the default and most commonly used window for reporting ad-attributed metrics within Amazon DSP. Understanding this default is crucial for accurately interpreting campaign performance data.
