The steps to refresh the category nodes on Amazon using a table are as follows:

First, enter the Best Seller category through the Amazon front desk, and keep clicking until you reach the smallest node.

In Amazon's large category template, find the BTG category guide. BTG is Inventory File Templates. Find the BTG of your product category from it. BTG is in Excel format.

According to the detailed introduction of BTG, you can find keywords suitable for your products. Keywords are category node IDs.

Enter the Seller Center and navigate to Inventory > Add products via upload.

After uploading the CSV table, you need to upload the CSV inventory template and the corresponding browsing node ID in the background.

After the upload is complete, you can view the listing and then further edit or adjust it. You can edit the listing by modifying the CSV file or directly clicking Inventory > Manage Inventory.

The above are the detailed steps to refresh the category nodes on Amazon using a table. I hope it will be helpful to you.
