亚马逊A9算法个人解析

• A9算法介绍（个人观点，有错我也不改）

 1.为什么叫A9算法.

1.算法单词Algorithm 刚好9个字数.
2.亚马逊参考标题，5点，ST，长描述，预期用途，商品类型，特定风格，相关主题，A+ 这9项Detail Page的具体组成部分来收录我们的产品.

2.什么是A9算法.

A9算法是一种排序算法，即亚马逊通过对客户的产品搜索、购买等行为进行精准记录和分析, 从亚马逊众多的产品类目中里挑选出客户搜索更为相关的产品，并根据相关性排序展示给客户, 以确保客户能尽快找到“想要购买的产品”。
Ps. 专业术语叫做追求最大化RPC（Revenue Per Customer买家收益）
对于RPC，其实就是考量产品是否符合顾客的需求,是否能激发顾客购买欲望，以及产品和服务是否能令顾客满意愿意重复购买.
相关性——符合客户搜索需要
转化率——激发顾客的购买行为
满意度&复购率——带来极致客户体验

2018年以前A9算法有过官方描述，现在可以通过时光机追溯原始页面

亚马逊官方对搜索算法的描述：
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话题挺火热的，这边顺便放一下我用AI询问出来的答案.
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.

• A9算法的原理（具体看思维导图.不展开讲了）

1 A9算法四大原理

1.Searching Indexing搜索收录
2.Product Relevance商品匹配度
3.Past Search Patterns 过往搜索痕迹
4.Past Traffic Patterns 过往流量痕迹

2 A9算法三大影响因素

1.转化率
2.相关性
3.顾客满意度&留存率

• 了解研究A9算法的意义

1.A9算法是亚马逊运营一切工作和优化的理论依据，最最权威的指南手册.
理解了A9算法，你就明白了怎么去优化你的Listing,你为什么要去花钱投放广告，一个卖家一个运营每天该去做些什么以及很多其他的问题.
2.锻炼数据分析能力，形成以数据说话的数据化思维.
3.有效拒绝镰刀，不当跨境小韭菜.

整理A9算法来开这个系列帖的原因挺多的.

1.1劣质资料满天飞，没有一个标准完善的回答.
1.2身边很多运营朋友的不了解和不重视.
1.3一拳打在无良服务商和讲师们的上巴上.

这几年跨境电商作为一个热门行业, a lot of (Boss)(投机资本)和打工同志们涌入.对这类专业知识和资源的需求提供了镰刀们存在的土壤,知识本身的垄断和获取渠道的封闭催生了良莠不齐的培训机构和讲师.什么水平什么性质大家也有目共睹.
开这个帖子单纯分享下个人见解，给后来者一些参考的信息.
附件里的思维导图既是A9算法的大致框架，也是亚马逊最基础需要掌握的知识点.在之后可能存在（我又懒又忙）的帖子系列里算是作为一个总目录吧.
