How will conversions be impacted (if at all) after a campaign ends?

The correct answer is that conversion insights may continue to come in after a campaign ends due to the 14-day lookback window. Amazon DSP's attribution model typically uses a 14-day lookback window, meaning that a conversion can be attributed to an ad impression or click that occurred up to 14 days prior to the conversion event. Therefore, if a customer saw or clicked an ad on the last day of the campaign and then converted within 14 days, that conversion would still be attributed to the campaign even after it has officially ended. The other options are incorrect because conversion insights do not stop 14 days before the campaign ends, and it's inaccurate to assume no insights will come in afterward due to the lookback window.
