The 5 Amazon FBA Metrics You Should Be Tracking Every Day

One thing I’ve learned working with Amazon sellers is this: growth doesn’t happen by chance. It happens when you track the right metrics and make decisions based on real data.

If you’re not paying attention to the numbers that matter, you’re leaving money on the table—or worse, risking your account. Here are the 5 key metrics every Amazon seller should track to stay profitable and keep their business healthy.

1. Order Defect Rate (ODR)

This is one metric Amazon takes very seriously. Your ODR is a combination of negative feedback, A-to-Z claims, and chargebacks. If this goes over 1%, you could face account suspension.

👉 Tip: Respond to negative feedback quickly, address customer concerns, and monitor your performance dashboard regularly.

2. Inventory Performance Index (IPI)

Amazon’s IPI score tells you how well you’re managing inventory. If you’re holding excess stock or have poor sell-through rates, your score takes a hit.

👉 Why it matters: A low IPI can mean storage limits and higher fees. Audit your inventory often, get rid of stranded stock, and keep things moving.

3. Conversion Rate (CVR)

Your conversion rate measures how many people view your product listing and actually make a purchase. Low conversions often mean something’s off with:

• Your product images
• Your pricing
• Your product descriptions

👉 Quick fix: Test and tweak. A/B test different images, refine your bullet points, and keep an eye on pricing strategies. Small changes can make a big difference.

4. Customer Acquisition Cost (CAC)

This one’s simple: how much does it cost you to acquire a new customer? You calculate it by dividing your advertising spend (like PPC) by the number of new customers you bring in.

👉 Why it’s key: If your CAC is too high, it eats into your profits. Focus on optimizing ad campaigns and finding more organic ways to drive traffic.

5. Repeat Customer Rate

Repeat customers are everything. Not only do they boost sales, but they also lower your customer acquisition costs over time.

👉 How to improve it:

• Build trust with great customer service
• Bundle products to encourage multiple purchases
• Follow up with buyers to make sure they’re happy (within Amazon’s guidelines, of course).
