Amazon A/B Testing – How to Run Split Tests for Higher Sales
In the fast-paced world of Amazon selling, small tweaks can make a big difference in conversions. That’s where A/B testing, also known as split testing, becomes an invaluable strategy. Whether you're trying different product titles, images, or pricing strategies, running data-backed experiments can help you discover what truly works to boost sales.
In this guide, we’ll break down everything you need to know about Amazon A/B testing in 2025—how it works, what you can test, and tools to do it right.
What is A/B Testing on Amazon?
A/B testing involves comparing two versions of a product detail element (like a title or image) to see which one performs better. Version A is your control, and Version B includes the change you're testing. Over time, you measure which version gets better engagement, conversions, or sales.
Amazon sellers can use A/B testing to:
- Improve product click-through rates (CTR)
- Increase conversion rates (CVR)
- Reduce return rates
- Better understand buyer behavior
How Amazon A/B Testing Works (Manage Your Experiments)
Amazon provides a built-in tool for split testing: Manage Your Experiments (MYE). Available to Brand Registered sellers, this feature lets you test different versions of:
- Product titles
- Main images
- Bullet points
- Product descriptions
- A+ Content
Here’s how to use it:
- Access the Tool: Go to Seller Central → Brands → Manage Your Experiments.
- Select an Eligible ASIN: Not all ASINs qualify. Your product must have high enough traffic to produce statistically meaningful results.
- Create Two Versions: Upload a Version A and Version B for the selected element.
- Set Duration: Amazon recommends a minimum of 4 weeks.
- Monitor Results: Amazon provides performance metrics to determine which variant wins.
💡 Pro Tip: Only test one variable at a time to isolate what’s driving the change.
💡 Pro Tip: Experiment with Listing Timing & Seasonality Split testing isn’t just about content—timing matters too. Test how your listings perform during peak vs. off-peak shopping periods. This helps uncover when your audience is most responsive and which version drives higher conversions. For example, run version A during a non-promotional week and version B during a sales event. Use SentryKit alerts to track changes in conversion rates, impressions, and reviews.
What Can You A/B Test on Amazon?
1. Product Titles
Try different keyword placements, formatting, or value propositions. Example:
- A: “Stainless Steel Water Bottle – 1L”
- B: “1L Leak-Proof Stainless Steel Sports Water Bottle – BPA Free”
2. Main Images
Images are key drivers of clicks. You can test:
- Angles or zoom levels
- Lifestyle imagery vs. product-only images

3. Bullet Points
Test clarity, formatting, or sequence of benefits. Some shoppers read these in detail!
4. A+ Content
Visual A+ pages can tell your brand story—but what layout, visuals, or headlines work best?
5. Product Descriptions
Try long vs. short formats or narrative vs. technical language.
