Amazon’s Algorithm in 2025: A10, Relevance & Ranking Signals
Amazon continues to fine-tune its search algorithm to improve customers’ shopping experiences in 2025, as it has done in previous years. The algorithm’s ranking system, more widely known as A10, determines the order in which products are displayed in search results. For sellers, knowing how this system operates is key to achieving greater visibility, conversions, and sales.
As Amazon’s previous A9 algorithm targeted sales metrics and keyword relevancy, A10 advances the scope of algorithmic targeting by incorporating brand equity, external traffic, customer metrics, and product relevance beyond the site. Sellers who take advantage of these signals will position themselves better relative to their competitors and bid for the highest-ranking spots.
What is the Amazon A10 Algorithm?
The A10 algorithm represents an evolution of Amazon’s A9 search system. Through the integration of on-Amazon dimensions (e.g., sales velocity and reviews) and off-Amazon dimensions (e.g., brand equity and external traffic), A10 determines which product listings are most relevant and trustworthy to the customer, and in turn, shapes the relevant search results.
More specifically, A10 seeks to reward sellers who build a brand on trust and sustained genuine engagement while punishing those who solely depend on strategies like paid ads and keyword stuffing. The algorithmic shift reflects Amazon’s commitment to customer satisfaction and brand equity.Differences between the A9 and A10 Algorithms Analysis
Factor A9 Algorithm (Old) A10 Algorithm (New)
Primary Focus Sales velocity & ads Relevance, authority, and engagement
Advertising Influence High Moderate
External Traffic Minimal impact Strong ranking signal
Brand Authority Not prioritized Highly influential
Customer Engagement Secondary factor Major ranking factor
Organic Visibility Based on conversion rate Based on relevance and authenticity
In the A10 revision, it appears that Amazon seeks to prioritize the organic performance of the seller and create an incentive for sellers who are able to develop a favorable and sustainable engagement with customers as opposed to those who rely on advertising and temporary boosts in sales to manage their accounts.
Core A10 Algorithm Ranking Signals:
1. Relevance and Keyword Optimization
In the ranking of factors for Amazon, keyword relevance remains an important ranking factor for Amazon. For A10 algorithms, Amazon still tracks the search terms to assess which listings correspond to user intent, but it is now placing greater emphasis on the semantics of the relevant keyword as opposed to keyword adjacency.
To rank higher:
– Put primary and secondary keywords in a natural way in your title, bullet points, and description.
– Focus on long-tail keywords that reflect buyer intent, e.g. “eco-friendly water bottle (instead of just “water bottle”).
– Use accessory search terms in a strategic way, avoiding duplication and irrelevant words.
A10 also interrogates your keyword context and ensures that your listings will match the meaning and purpose of the buyer’s search.
2. Click-Through Rate (CTR)
Amazon interprets a high Click-Through Rate (CTR) as a signal that a product listing is relevant and attractive. Under A10, more visibility is given to listings that have:
– Interesting titles
– High-quality main images
– Competitive prices
– A higher number of positive reviews
Your CTR improves when your product listing becomes one of the more highly ranked products among its competitors. This is A+ ranked visuals along with persuasive copywriting.
3. Conversion Rate (CR)
Once a product listing is clicked, the CR is the measurement of the likelihood that the product will be purchased. A10 also rewards listings that have positive sales performance with minimal bounce rates.
Your CR can be increased by:
– Writing clear, benefit-oriented product descriptions
– Using lifestyle images alongside infographics
– Using A+ Content to build trust
– Emphasizing unique selling propositions/points (USPs)
Amazon requires as well as wants products that can provide consistent sales as this improves user experience and revenue earned from the sales.
4. Sales Velocity and Historical Performance
Sales velocity under the A9 model has less dominance compared to A10, still, it is a significant determinant of success. A10 prioritizes consistent sales growth over temporary spikes that are visible in ad campaigns.
Stable long-term sales occurrences build the trust of a customer which in turn provides ranking stability. This reliable sales trend has a strong influence on the sales ranking of the listing.
5. Off-Amazon Traffic
Amazon seems to be focusing on off-Amazon traffic sources including social media (TikTok, Instagram, Facebook), YouTube influencer campaigns, blog mentions and backlinks, and Google Search traffic. A10 views outside traffic as a testament to the strength and authenticity of a brand. When new visitors are brought to Amazon via your marketing channels, it shows that the product you are marketing is of a great value and worth the trust which strengthens your ranking power.
6. Brand Authority and Loyalty
Amazon evaluates the brand’s registry status, product catalog consistency, and customer loyalty (repeat purchases, brand searches, and engagement through Storefronts and Amazon Posts) to gauge the brand authority. Higher ranking is likely for brands that consistently maintain their identity, receive positive feedback, and build a strong customer base.
Ways to Build Brand Authority:
Enroll in Amazon Brand Registry.
Create a Branded Amazon Storefront.
Encourage followers to search for your brand name on Amazon.
Customer Reviews and Ratings
Reviews are still a very important part of Amazon’s ranking system. A10 takes into account:
Verified purchase reviews
Frequency of reviews (consistent positive feedback)
Detailed reviews that are authentic and have helpful votes
Spam or fake reviews are harmful to visibility. Make sure to ask for genuine reviews after a purchase and provide excellent service.
Inventory Health and Fulfillment
Amazon’s system prefers listings that are in stock and are eligible for Prime membership and fulfilled quickly. Continual stockouts are a sure way to harm ranking.
Using Fulfillment by Amazon (FBA) for order processing ensures quicker delivery and increases trust which in turn increases visibility.
How Off-Amazon Factors Influence Rankings in 2025
In 2025, Amazon’s system also uses external engagement metrics for determining rankings. For instance:
A viral TikTok can drive lots of off-Amazon traffic and increase your visibility.
A product on Google Discover or Pinterest can boost Amazon listing views.
Reputable blog mentions can increase brand trust and credibility.
Using many different ways to promote your products provides evidence to Amazon that your listings are high authority which improves rankings and increases the likelihood of conversion.
Strategies for Visibility under the A10 Algorithm
Increased visibility under A10 requires the following strategic priorities.
Prioritize Relevance – Target specific search intent to improve the match between user intent and your offer.
Build Brand Trust – Foster brand trust by maintaining consistency and communicating within your Amazon Stores.
Encourage Genuine Feedback – Automated follow-up emails and exceptional customer service are important to garner reviews.
Optimize External Promotions – Use social media, influencer marketing, and blogging to attract customers to your Amazon listings.
Enhance Your Listings – Increase the number of your images, describe your value propositions, and improve text to foster your listing’s rank.
Track Your Stock – Your rank will be best sustained when you avoid stockouts.
Analyze Your Data – Keyword and conversion rate trend analysis are useful for strategic planning and systems like Amazon Brand Analytics or Helium 10 provide these insights.
Amazon’s Future Algorithm
Amazon’s algorithm will incorporate more facets of AI and personalization. Beyond 2025, Amazon will probably integrate:
Real-time analysis of customer sentiment contained in reviews and questions and answers sections.
Voice search capabilities for Alexa users.
Increasing consumer sentiment will reward sellers of eco-sustainable and sustainably sourced products.
Sellers who maintain adaptive A10 system-driven engagement and customer satisfaction will continue to provide value.
Conclusion
With A10 comes another step in the right direction in terms of authenticity, trust, and relevance on the platform by Amazon. A10 provides for the first time the possibility of distance for sellers, as A10 focuses on off-platform influence and long-term performance rather than aggressive advertising campaigns.
To thrive in 2025, sellers will have to complement on-Amazon efforts with robust off-Amazon marketing. Consistent products, valuable content, and an audience cultivated over time will be necessary to ‘win’ the algorithm.
You have mastered A10 and are therefore selling, not just products, but trust and recognition as a brand on the largest marketplace on the Internet.
