Detailed explanation of Amazon A9 algorithm: from keyword layout to category node card control

The core of the Amazon A9 algorithm lies in how to improve the search ranking of products through multiple steps such as keyword layout, inclusion, sorting, and category node control. This article will introduce this process in detail to help sellers better understand and apply the A9 algorithm.

Step one: Keyword layout and buried words

The first step in running the Amazon A9 algorithm is keyword layout, which is to bury words in the product page to let the system understand what type of product you are selling. Buried words mainly involve four important positions: Title (title), Bullet Points (five-point description), Search Terms (backend keywords) and Product Description (product description). These positions are ordered from highest to lowest weight as follows: Title > Bullet Points > Search Terms > Product Description. Title has the highest weight and is therefore the most critical. When burying words, you must not only look for all words related to the product, but also ensure that these words are embedded in the above four areas in a natural and smooth way to avoid over-stuffing of keywords that affects the readability of the content.

It’s worth noting that Amazon indexes individual words, not phrases. This means that even if keyword A appears in the title and keyword B is in the Search Terms section of the backend, as long as the user searches for “A+B”, the product will still appear in the search results without the need for the two to appear next to each other or use a comma Separate. In addition, repeated use of the same words will not help improve rankings. Words already included in the Title should be avoided from appearing again in Search Terms.

Step 2: Keyword inclusion test

After completing the keyword layout, the next step is to ensure that Amazon has included these keywords and check the inclusion status. A simple and effective method is the ASIN + keyword test method: Take power bank as an example, if the ASIN is 123456ABCDE, you can enter “123456ABCDE PowerBank” in the front search box to check whether the product appears in the search results to determine the keyword Whether it has been included. If you find that some keywords are not included, you can add them to the title and set the exact match mode with the on-site CPC advertisement, and increase the bidding amount to about $24 for about 35 days, which can usually speed up the inclusion process.

Step 3: Keyword ranking optimization

After the keywords are successfully included, the next task is how to optimize their ranking in the search results. According to the principle of the A9 algorithm, the key factor that determines the product ranking under a certain keyword is the conversion rate brought by the keyword, not the overall conversion rate of the entire product page. In other words, the higher the conversion rate of a single keyword, the higher the search results ranking for that keyword will be. Therefore, newly launched products can improve the natural ranking of specific keywords by inviting local friends in the United States to use core keywords to search and complete purchases.

Step 4: Category node selection and control

The last step involves the selection and management of the category to which the product belongs. Each product will be classified into a specific category on the Amazon platform. Choosing the right category correctly will not only help increase the exposure of the product in the search results, but also increase the chance of discovering the product through category browsing (Browse). In order to ensure the best results, it is recommended to refer to products with excellent performance in the same category to set the category. At the same time, it is very important to keep the category stable. Frequent changes may cause the existing rankings and weights to be reset.

In short, by in-depth understanding and application of the rules of Amazon’s A9 algorithm, sellers can manage and optimize their product lists more effectively, thereby obtaining higher search rankings and more attention from potential customers. Although there are rumors that Amazon may adjust the existing algorithm system, judging from the current actual operation, the A9 algorithm still plays an important role.
