Overview

Amazon credits a Sponsored Products sale only when a shopper clicks the ad and completes the purchase within the next seven calendar days. Choosing a reporting window that mirrors this seven‑day attribution period lets sellers read true performance numbers and make budgeting choices on solid data.

Key Points

• Seven‑day attribution rule — A conversion is linked to an ad if the purchase occurs any time during the seven days after the click, meaning a March 1 click still counts if the order ships on March 7.
• Bulk of conversions happen early — Approximately 87 % of ad‑driven orders are recorded within the first three days, so short‑term data carries the most weight for evaluating keyword efficiency.
• Longer windows blur actionable insights — Extending the view to 30 or 60 days mixes fresh clicks with older ones, inflating ACOS and diluting ROI signals that are critical for day‑to‑day bid tweaks.
• Seasonal peaks stretch the decision timeline — During high‑traffic events such as Prime Day or holiday weeks, shoppers may wait up to six days before buying, still fitting inside the seven‑day rule but urging sellers to broaden the view slightly for those periods.
• Precise windows drive smarter bid moves — When the date range matches the attribution period, sellers can isolate under‑performing keywords quickly and reallocate spend without reacting to lagging, irrelevant data.
• Inventory planning benefits from accurate velocity — Knowing the exact conversion speed inside the seven‑day window helps forecast replenishment needs, reducing the chance of stockouts when demand spikes.
• Reporting consistency across campaigns — Applying the same seven‑day window to all Sponsored Products campaigns creates a uniform baseline, making cross‑campaign comparisons reliable and preventing misinterpretation caused by mixed timeframes.

How to Choose the Right Date Range for PPC Analysis

1. Lock onto the core seven‑day attribution window — Begin by configuring reports to capture only the seven days that follow each ad click. A click on April 10 contributes sales up to April 17; any order after April 17 is excluded from that click’s metrics.
