Overview

Amazon Seller Central provides sellers with reporting tools to measure the effectiveness of their promotions. By linking promotion IDs to order-level data, sellers can evaluate whether their Buy One Get One (BOGO) and percentage-off promotions are driving meaningful results or simply cutting into margins.

Key Points / What Sellers Need to Know

• Promotion ID is your tracking key — Every promotion you create in Seller Central is assigned a unique Promotion ID, which appears in your order reports and allows you to connect specific sales back to the promotion that drove them.
• Two reports contain promotion data — Your Promotion ID surfaces in both the Order Report and the Order Item Report, giving you visibility at both the order level and the individual product level.
• Redemption rate matters most — The reports let you calculate what percentage of customers actually redeemed your promotion, helping you gauge whether shoppers are noticing and responding to your offers.
• Cumulative cost tracking is built in — You can tally up the total discount cost of a promotion across all qualifying orders, making it straightforward to compare promotional spend against incremental revenue.
• Qualified vs. non-qualified order comparison — The data lets you compare the average order size for customers who qualified for your promotion against those who did not, revealing whether promotions are actually increasing basket size.

How Promotion Tracking Works

When you create a promotion in Seller Central — whether it is a Buy One Get One deal, a percentage-off discount, or another offer type — Amazon assigns it a unique Promotion ID. This identifier then gets attached to every order that qualifies for or redeems that promotion. You can find this ID by navigating to the Promotions section under the Advertising tab in Seller Central. Once you have the ID, you can cross-reference it against your downloadable order reports to isolate exactly which transactions were influenced by your promotional activity.

Analyzing Promotion Effectiveness

The real value of these reports lies in the analysis they enable. Sellers should focus on three core metrics when evaluating a promotion. First, look at the redemption rate — the percentage of eligible customers who actually used the promotion. A low redemption rate may indicate poor visibility or an unappealing offer. Second, examine the average order value for promoted versus non-promoted orders. If your promotion is not lifting basket size, it may simply be discounting sales that would have happened anyway. Third, calculate the cumulative cost of the promotion by summing all discounts given, and weigh that against any lift in total units sold or revenue during the promotional period.
