Overview

Amazon displays a "Sales Trend" badge on product listings that gives shoppers a rough idea of how many customers have recently bought a particular item — for example, "10K+ bought in past month." While sellers cannot opt out of this feature, understanding how it works and what drives it can help you use it to your competitive advantage.

Key Points / What Sellers Need to Know

• Sales Trend is a customer-facing estimate — It shows shoppers an approximate count of recent buyers for a product, helping them gauge popularity at a glance.
• Data refreshes at least daily — Amazon updates these numbers frequently, and the count excludes returns and cancellations, so it reflects genuine completed purchases.
• Not all ASINs display a badge — A minimum purchase threshold must be met before the badge appears, and not every product category is currently eligible.
• You cannot turn it off — Like Best Seller badges, Amazon's Choice labels, and Best Sellers Rank, the Sales Trend badge is controlled entirely by Amazon and cannot be disabled by sellers.
• It counts customers, not units — The metric tracks unique buyers across all sellers of that ASIN, so it will not match your individual unit sales or order counts in Business Reports.

How Sales Trend Is Calculated

Amazon's Sales Trend metric estimates the number of individual customers who have purchased a specific ASIN within a recent time window. This is an important distinction: it counts buyers, not total units sold or total orders placed. If one customer buys three units, that registers as a single customer in the sales trend figure. The data also spans every seller offering that particular ASIN, meaning the badge reflects the product's overall popularity rather than any one seller's performance. Returns and cancellations are stripped out of the calculation, so the number represents completed, legitimate purchases.

How Variations Are Handled

The way Amazon displays Sales Trend data depends on whether a customer is viewing a child ASIN or a parent ASIN. When a product page shows a specific variation — say, a particular color or size — with a single price, the sales trend badge reflects purchases of that individual child ASIN only. However, when the listing presents the parent ASIN with a range of prices across all variations, the badge aggregates the total customer count across every child ASIN in that variation family. This means a parent listing can display a significantly higher number than any single variation would on its own, which can make multi-variation listings appear more popular to browsing customers.
