Overview

Amazon has begun displaying a new “sales trend” badge on product detail pages, showing an estimated recent purchase volume such as “10K+ bought in past month.” The feature launches in select categories this quarter, and sellers should watch it because the badge adds a visible social‑proof cue that can sway click‑through rates and conversion performance.

Key Points

• Badge content — Eligible listings show a rounded figure (e.g., “12K+ bought in past month”) that represents the total units sold during the most recent 30‑day window.
• Automatic qualification — Amazon adds the badge automatically once a product crosses the hidden threshold; there is no opt‑in or manual enrollment required.
• Initial category rollout — The first wave covers health & personal care, home, and sports & outdoors, with Amazon indicating that additional categories may follow later in the year.
• Rolling purchase window — The estimate updates daily based on the last 30 days of sales, so a badge can appear, disappear, or change from “5K+” to “15K+” as momentum shifts.
• Absolute vs. relative metric — Unlike Best Seller Rank, which ranks products against peers, the sales trend badge reports an absolute sales range that shoppers can read without interpreting a rank number.
• Broad estimate ranges — Numbers are presented in wide bands (e.g., 1K‑5K, 5K‑10K, 10K+), preventing competitors from seeing exact figures while still conveying demand strength.
• No impact on pricing algorithm — The badge does not alter Amazon’s price‑adjustment logic; it is purely a visual cue on the detail page.
• Visibility effect — Early tests in the home category showed listings with the badge enjoyed a 7% higher click‑through rate compared with identical listings lacking the badge.

How the Sales Trend Badge Works

1. Threshold detection — Amazon continuously monitors each eligible SKU’s sales over the past 30 days; when a product exceeds the internal volume threshold (for example, 8,000 units), the system flags it for badge generation.
