The gauge shows your estimated Win Rate %.
Pro Strategy
- If you are FBA and they are FBM, you can likely price 5-10% higher and still win.
- Don't obsess over 100% win rate. Sometimes it's better to share the box at a higher profit margin than win it all at $0 margin.
- Seller Rating matters less than Price, but poor metrics (<90%) will kill your eligibility entirely.
Core Concepts
The Buy Box
The white box on the right side of the Amazon product page containing the 'Add to Cart' button. 82% of sales go to the Buy Box winner.
FBA Advantage
Fulfillment by Amazon (Prime) is a massive ranking factor. An FBA seller can often price higher than an FBM seller and still win the box.
Price War
Automated repricers lower prices to win the box. Set a 'Floor Price' to avoid selling at a loss.
