1. First, find the product category on Amazon's official website.

You can see the type of products for sale through the products searched on the homepage.

At this time, you can search for the desired product through the product category page or the search bar you are used to.

2. Then, you can click to select the product, and then click all other options in the drop-down list. Following this step, you can select all products or select a classification catalog.

Then click a product category in the drop-down list.

Select all product categories in the list.

3. At this time, you can click on the product category.

At this time, you can select all products or select different categories.

Then you can click on the last save category, that is, you can select different categories.

4. When choosing which product category to choose, you need to pay attention to the fact that the products are in different categories, where Amazon allows two products of the same brand (one of which is a brand) and the other is a type of choice.

However, several other types of product categories cannot pass category review.
