BS (Best Seller)

On Amazon, Best Seller is a dynamic label awarded to the product with the highest sales volume in a specific category over a recent time window (usually updated hourly). These products receive a “Best Seller” badge, which is shown on the product detail page and in search results.

Key points:

• The badge is category-specific - a product can be a Best Seller in one category but not in others
• Rankings are determined by sales velocity, not reviews or ratings
• Badges help drive higher click-through rates (CTR) and conversion rates

Where it appears:

• Product listing page (orange “#1 Best Seller” badge)
• Search results
• Category bestseller pages (e.g., amazon.com/Best-Sellers)

Why it matters:

• Indicates high demand and strong sales momentum
• Boosts credibility and trust with customers
• Can improve organic ranking due to higher engagement
• Helps identify trending products for competitive analysis or sourcing

💡 Example: A yoga mat with steady daily sales can outrank others in the “Exercise Mats” subcategory and earn the #1 Best Seller badge.

In short: BS means a product is the top-selling item in its Amazon category - earning a badge that increases visibility, trust, and sales potential.
