Amazon A10 Algorithm in 2025: How to Optimize Your Listings for Maximum Sales
If you’re an Amazon seller, staying ahead of the competition requires understanding how Amazon’s search algorithm ranks products. Over the years, Amazon has evolved from the A9 algorithm to the more advanced A10 algorithm, placing greater emphasis on organic engagement, external traffic, and customer experience rather than just sales velocity and paid ads.
So, what does this mean for your Amazon SEO strategy in 2025? This guide breaks down the key differences between Amazon’s A9 and A10 algorithm and provides actionable strategies to help your listings rank higher and drive more sales.
A9 vs. A10: What’s Changed?
Amazon A9 Algorithm (Previous Model)
The A9 algorithm primarily focused on sales velocity. The more a product sold, the better it ranked.
Other key ranking factors included:
- Sales history and velocity (high sales = better ranking)
- Keyword relevance in titles, bullet points, and backend search terms
- Click-through rate (CTR) and conversion rate (CR)
- Competitive pricing
- Amazon PPC ads boosting ranking
Amazon A10 Algorithm (Current Model)
The A10 algorithm has shifted ranking factors to prioritize organic engagement and external traffic over paid advertising.
Key differences include:
- External traffic matters more – Amazon rewards products that bring in traffic from Google, social media, and influencers.
- Organic sales have a stronger impact on rankings than PPC – Paid ads alone are no longer enough to improve ranking.
- Seller authority and reputation influence visibility – Strong feedback scores, low order defect rates (ODR), and good customer service help improve rankings.
- Customer engagement metrics matter – Time on page, review quality, and user interactions now play a role.
- High-quality listing content is prioritized – A+ Content, videos, and detailed FAQs improve rankings.
Key Takeaway: If your strategy relies only on PPC ads, your rankings may suffer. To succeed in 2025, you need a well-rounded Amazon SEO strategy focused on organic traffic, high-quality content, and strong seller metrics. Learn how to optimize your listings in our Amazon SEO guide!
How to Optimize for Amazon’s A10 Algorithm in 2025
Amazon SEO is more competitive than ever, and to rank high, sellers must adapt their strategies. Here’s how:
1. Drive External Traffic to Your Amazon Listings
Amazon now prioritizes products that bring traffic from outside its platform.
To stay competitive, sellers should:
- Leverage Google SEO & Google Ads – Optimize your product pages for high-intent searches. Use Google Search Console to monitor search performance and improve visibility outside Amazon.
- Utilize Social Media Marketing – Platforms like TikTok, Instagram, and YouTube can drive qualified buyers.
- Partner with Influencers & Bloggers – Influencer-driven referral traffic signals to Amazon that your product is in demand.
Pro Tip:
External traffic is a major ranking factor in A10. The more customers you bring from outside Amazon, the better your organic rankings.
2. Optimize Your Listings for Higher Engagement
Amazon favors listings that keep shoppers engaged.
Improve your product detail page by:
- Writing compelling product titles and descriptions with relevant keywords.
- Using A+ Content and videos to provide an engaging shopping experience.
- Adding an FAQ section to answer common questions and reduce purchase hesitation.
Pro Tip:
The more time shoppers spend on your listing, the higher Amazon ranks your product.
3. Build Strong Seller Authority & Reputation
Amazon now evaluates sellers based on their overall performance.
To improve your seller authority:
- Maintain high feedback scores and keep order defect rates (ODR) low.
- Encourage more reviews by providing excellent customer service and sending follow-ups that remind buyers to share their experience.
- Offer reliable shipping and prompt customer support to maintain a strong seller rating.
Pro Tip:
Sellers with high ratings and good performance metrics get better visibility in search results.
4. Focus on Organic Sales & Brand Loyalty
Amazon rewards sellers who generate repeat purchases and build customer trust.
To improve your organic ranking:
- Enroll in Amazon’s Brand Registry to unlock exclusive marketing tools.
- Offer discounts and subscribe-and-save options to encourage repeat purchases.
- Use Amazon Posts and social proof to increase product visibility.
Pro Tip:
Returning customers signal to Amazon that your product is high quality, improving organic rankings.
Common Amazon A10 Mistakes (and How to Fix Them)
Even experienced sellers make critical errors when adjusting to Amazon’s new ranking system.
Avoid these common pitfalls:

- Neglecting external traffic sources – Amazon prioritizes off-platform traffic.
- Ignoring engagement metrics – Poor CTR and low dwell time can hurt rankings.
