亞馬遜A9算法個人解析

A9算法介紹（個人觀點，有錯我也不改）

1.爲什麼叫A9算法.

1.算法單詞Algorithm 剛好9個字數.
2.亞馬遜參考標題，5點，ST，長描述，預期用途，商品類型，特定風格，相關主題，A+ 這9項Detail Page的具體組成部分來收錄我們的產品.

2.什麼是A9算法.

A9算法是一種排序算法，即亞馬遜通過對客戶的產品搜索、購買等行爲進行精準記錄和分析, 從亞馬遜衆多的產品類目中裏挑選出客戶搜索更爲相關的產品，並根據相關性排序展示給客戶, 以確保客戶能儘快找到“想要購買的產品”。
Ps. 專業術語叫做追求最大化RPC（Revenue Per Customer買家收益）
對於RPC，其實就是考量產品是否符合顧客的需求,是否能激發顧客購買慾望，以及產品和服務是否能令顧客滿意願意重複購買.
相關性——符合客戶搜索需要
轉化率——激發顧客的購買行爲
滿意度&復購率——帶來極致客戶體驗

2018年以前A9算法有過官方描述，現在可以通過時光機追溯原始頁面

亞馬遜官方對搜索算法的描述：
If you've done a search on Amazon,you've used our search engine.

Our work starts long before a customer types a query. We've been analyzing data, observing past traffic patterns, and indexing the text describing every product in our catalog before the customer has even decided to search. As soon as we see the first keystroke, we're ready with instant suggestions and a comprehensive set of search results.
最近AI話題挺火熱的，這邊順便放一下我用AI詢問出來的答案.
What is the A9 algorithm search engine mechanism of Amazon platform and what is the logic of A9 algorithm?

The A9 algorithm, also known as the Amazon Search Algorithm, is the search technology used by Amazon to help customers find products on its platform. The main goal of the A9 algorithm is to provide relevant search results to customers, based on their search query, in order to improve the overall user experience.
The logic behind the A9 algorithm involves a combination of factors, including:
Relevance: The algorithm considers how closely a product matches the keywords in a customer's search query, as well as other factors such as product title, description, and category.
Sales Velocity: The algorithm also considers the popularity of a product based on its recent sales history. Products that have been selling well are considered more relevant than those that haven't.
Availability: The algorithm takes into account whether a product is currently available and in stock, as well as the estimated delivery time for each product.
Customer behavior: The algorithm considers the past search and purchase behavior of each customer, using this information to personalize search results.
Product ratings and reviews: The algorithm also considers the ratings and reviews of products, as well as the reputation of the seller.
By taking all of these factors into account, the A9 algorithm is able to deliver relevant search results to customers and help them find the products they are looking for on Amazon.
