You can follow the steps below:

Visit the eBay website and register an account. If you already have an account, please log in directly.

Click the "My eBay" button in the upper right corner of the webpage and select the "Seller Center" option.

On the "Seller Center" page, select the "Start Selling" button and then select "Create a Store."

Fill in basic information such as store information and bank information as required, including store name, store policy, product classification and operating area.

After filling in the store information, you need to upload at least one product list to complete the store opening. You can set product prices, descriptions, pictures and other details as needed, and choose the appropriate shipping and payment methods.

After completing the product settings, your store has been successfully opened. At this time, you can manage your store through the store homepage to edit store information, add new products or manage orders.

It should be noted that before opening a personal store, you need to understand and confirm eBay's seller policies and handling fees to ensure that your store complies with the regulations and standards of the eBay platform. In addition, in order to increase product exposure, you can also consider using advertising and other services to increase product sales.
