The process of listing items on eBay is as follows:

1. **Register as a seller**: You need to log in to the eBay official website and click "Items for sale" in the upper right corner to start the registration process. Then enter the details of the item you want to sell and select the category that matches the item you are selling. Then enter or edit the information for the item and click "List".

2. **Set title and subtitle**: Set a title containing keywords for your product to facilitate buyers to search for your product. It is usually recommended that the title be within 80 characters. You can also add a subtitle to provide more descriptive product information to increase buyer interest. The subtitle can use 55 characters.

3. **Upload pictures**: Upload high-quality pictures of your product, preferably with a white background, and the product accounts for 80% of the picture. Make sure the picture reflects as much detail as possible to give viewers a real feeling about your goods.

4. **Select Category**: When listing an item, you need to select the appropriate category, which will help buyers find your product in the correct category.

5. **Describe the item**: In the item description setting module, you can select "Standard" to enter the item description directly, or click "HTML" to use HTML code to add a more complex item description.

6. **Check and Submit**: Before submitting, check whether your contact information is correct and edit it if necessary. After ensuring that all information is accurate, submit your item listing.

7. **Link Payment Account**: Link your Payoneer account and complete the authentication in order to settle the transaction. Please note that it may take 3-5 working days for seller registration and authentication, during which time you may not be able to list items.

Please note that the above steps may vary depending on the different eBay sites (such as the US site, the UK site, etc.), and you should refer to the specific guidelines of the local site for specific operations. In addition, make sure to comply with eBay's rules and policies to avoid violations that may lead to account restrictions or bans.
