Amazon orders have a certain impact on product ranking, but the specific factors may be complex and cannot be fully determined.

Here are some possible ways of impact:

1. Sales volume: The number of Amazon orders can be used as an indicator of product sales volume. Generally speaking, products with higher sales volume are more competitive in ranking. Amazon's ranking algorithm may consider product sales data and rank products with higher sales volume higher.

2. Reviews and ratings: Many Amazon users refer to other users' reviews and ratings to decide to buy, so high-quality reviews and ratings can increase product sales. Higher ratings and positive buyer feedback may have a positive impact on product ranking.

3. On-page click-through rate (CTR): The number of clicks on the product on the Amazon page may also affect the ranking. If a product has a high exposure rate in the keyword search results, but a low click-through rate, Amazon may lower its ranking and believe that the product is not attractive enough to users.

4. Advertising campaigns: Through Amazon advertising services, sellers can run ads to increase exposure and click-through rates. Advertising campaigns may help increase the number of orders for a product, which in turn has a positive impact on rankings.

Please note that Amazon's ranking algorithm may combine multiple factors to determine the ranking order of products, and the specific weights and influencing factors may be adjusted at any time. In addition, the ranking algorithm for each market and category may also be different. Therefore, it is recommended that sellers focus on multiple factors such as quantity, quality, and marketing activities to increase product visibility and sales, rather than relying solely on the number of orders.
