If you’ve noticed a drop in your Buy Box percentage this year, you’re not alone.
Many Amazon sellers are seeing Buy Box suppression even when they’re FBA, priced competitively, and rated well. This isn’t a glitch – it’s the result of new 2025 algorithm changes that favor different seller behaviors than in years past.
Here’s what changed – and what you can do to reverse the trend.
What Is the Amazon Buy Box?
The Buy Box is the default “Add to Cart” option on a product detail page. It funnels 80–90% of all Amazon sales.
Only one seller wins the Buy Box at any given moment, even if 20+ offers exist. That winner gets nearly all the conversion.
Without the Buy Box, your listing becomes invisible to most shoppers.
Why Are Buy Box Wins Dropping in 2025?
đź”» 1. Amazon Prioritizes Delivery Speed, Not Fulfillment Type
In the past, being FBA almost guaranteed the Buy Box. Now, actual delivery time to customer is more important than whether you’re using FBA or FBM. If another seller can offer faster regional delivery – even via FBM – they may get the box.
đź”» 2. Price Stability Now Matters More Than Undercutting
The algorithm now flags erratic price changes as risky. Sellers using hyper-aggressive repricing tools are getting penalized for volatility.
đź”» 3. Price Parity Across Channels
Amazon is scanning pricing on Walmart, eBay, and your DTC site. If your product is listed cheaper elsewhere, your Amazon listing may lose the Buy Box – even if your price is competitive on Amazon.
đź”» 4. Listing Health + Return Rates Are Being Weighted More
Listings with high return rates, suppressed bullet points, missing images, or poor A+ content are seeing reduced Buy Box eligibility – even if seller metrics are strong.

-
High return rate on two color variants
-
Price was $3 lower on Walmart
-
