What are the 4 criteria for Amazon ranking weight? How to improve？

The Four Criteria for Amazon Ranking Weight:

The four criteria for Amazon ranking weight are the order defect rate, cancellation rate, late shipment rate, and effective tracking rate.

Amazon's ranking rules are governed by the A9 algorithm, which employs a scoring system to evaluate listings. When Amazon buyers search for keywords, the A9 algorithm selects products highly relevant to those keywords from various product categories and presents them to the buyers. Products with higher scores are more likely to rank higher in the search results page. The A9 algorithm evaluates Amazon listings based on the following three dimensions:

1. Relevance to Keywords: The A9 algorithm considers factors such as the listing title and product description to determine which keywords trigger the display of your listing.
2. Product Conversion Rate: Amazon prioritizes products over stores, so a high conversion rate indicates the quality and value of the product. Therefore, sellers should focus on improving product quality and maintaining good reviews.
3. Customer Satisfaction: The A9 algorithm evaluates customer satisfaction based on Amazon buyer feedback and the order defect rate.

In addition to the above factors, Amazon's emphasis on FBA (Fulfillment by Amazon) promotion and encouragement for sellers to use FBA services means that products using Amazon logistics are more likely to rank higher in search results.

In summary, the four criteria for Amazon ranking weight are the order defect rate, cancellation rate, late shipment rate, and effective tracking rate. Key factors influencing Amazon product search ranking include sales volume, positive feedback rate, and performance indicators.
