Amazon SEO is one of the most important methods for sellers on the platform to reach more customers and increase their sales. Just like Google, Amazon operates with a search engine logic and uses its own algorithm. The purpose of this algorithm is to determine the order in which users see the products they are searching for. As a result, customers often base their purchasing decisions on this ranking. At this point, Amazon’s A9 and A10 algorithms come into play. So, what do these algorithms mean, and what are the key differences between them?
What is the Amazon A9 Algorithm?
The Amazon A9 algorithm was the main system that organized product rankings on the platform for a long time. Its methodology focused on sales history, keywords in product descriptions, and price. Most importantly, it was sales-driven. In other words, the more a product sold, the higher the algorithm ranked it. The aim was to create a sales-oriented system.
However, the downside was that it made it much harder for new products to be discovered.
What is the Amazon A10 Algorithm?
The Amazon A10 algorithm was introduced to address the shortcomings of A9. This time, the priority was to enhance user experience. Unlike A9, the A10 algorithm is not just about sales figures but also about customer satisfaction and product reliability.
The main principles of the A10 algorithm include:
- Time users spend on the product page
- How informative and clear product descriptions are
- The number and quality of customer reviews
- The ratio of organic sales to paid (advertised) sales
- The seller’s overall performance and customer satisfaction
As these factors show, Amazon now focuses not only on sales but also on improving the overall customer experience.
Key Differences Between the A9 and A10 Algorithms
The biggest difference between the A9 and A10 algorithms is the shift in focus. While the A9 system was sales-oriented, the A10 system prioritizes customer satisfaction and trust in the product. Other notable differences include:
- While A9 placed more emphasis on advertising spend, A10 considers organic sales to be more valuable.
- In A9, the time users spent on a product page was not a major factor, whereas in A10 it is a strong ranking signal.
- A9 made it difficult for new products to gain visibility, but A10 allows high-quality content and proper optimization to help new products rise faster.
- In A9, seller performance had limited impact, while in A10, factors such as customer satisfaction, fast shipping, and return rates carry significant weight.
Strategies to Adapt to the A10 Algorithm
For brands that want to succeed with A10, focusing only on sales is no longer enough. High-quality content and customer satisfaction now play a central role in building trust and improving rankings. Key strategies include:
- Provide clear, complete, and accurate product information.
- Use high-quality photos and visuals that show the product in use.
- Encourage satisfied customers to leave reviews—one of the most effective ways to improve rankings.
- Advertising is still valuable, but organic preference signals much stronger reliability.
- Fast delivery, easy returns, and strong customer service are critical factors for A10.
