Method one
First enter the seller center, click I want to publish, and then jump to the category selection page. If you put the main keywords of your product in the category selection box, there will be a long input box. Put your main keyword in, and then press enter, and he will automatically help you choose the corresponding category. Because categories are automatically matched according to keywords, sometimes the categories you want may be different. If you are not yourself, you can adjust it manually.
Method 2
Take your product subject words and go to your e-commerce platform for search. Then sort by sales volume, see which category of peers sells better, and refer to the categories they put. Because it is a virtual product, it is generally recommended to refer to the categories put by peers to avoid the problem of penalty points for violations.
If you don't know what category to put your peers in, take Taobao Tmall as an example. You can search Baidu, store detective plug-ins, download and install them on your browser, refresh the peer baby page, and you can see them at the top of the main picture. The free function of this plug-in is enough for us to use, and there is no need to pay.
