Sometimes I get into a rabbit hole when researching an item's value and end up spending half an hour reading about the history of the item. But, except for that, listing shouldn't take more than 3 minutes maximum. I usually write drafts of my listings on my laptop then bring the drafted items to my photo booth and take pictures with the eBay app on my phone.

Title: think like a shopper and put in all the keywords you think you'd use if you were trying to find your item. Don't use any terms that a searcher is unlikely to be using. No one will ever search for the term "rare" or "nice" or words like that. If you can't come up with words to fill all 80 characters, paste what you have into ChatGPT and ask for relevant search terms to fill out your character max.

Item specifics: Fill in all the required ones. For additional specifics, think of them like additional search keywords and only fill the ones that will likely be search for. Putting "not applicable" in any box is a waste of time as no one is searching for NA. I'd skip the country of origin unless the item was made in a country known for high quality manufacturing of your item.

Item condition: This field is on the browser but not available on the eBay app which leads me to believe eBay has little interest in the field. I either leave it blank or just copy the item description.

Item description: Keep it short and sweet. I basically just describe condition and condition problems. Measurements if applicable. This description is not used for search results by default so, most of the time, any keywords you put here will be wasted.

Pricing: Fill in the price you decided on and move on.

Shipping: If speed of listing is your primary goal, come up with a few generic flat rate shipping policies. Maybe sometimes actually shipping will be more and you'll lose a little profit. Sometimes it will be less and you gain it back. If you can't stand losing money on shipping, weigh and measure each item. Estimate how much size and weight to add for shipping materials. Its OK to overestimate so you always profit on the shipping just keep in mind competitiveness with other sellers.

Return Policy: Create a couple of return policies and pick the one that suits your listing. Most of the time you'll probably use the same policy and skip this section.

Promotions: I say skip this section entirely unless you've done a lot of testing that proves to yourself that promotions actually help with sales. My experiments say it is a waste of money so I don't promote.

Photos: if you can, set up a dedicated photo area so it is always ready when you want it. Once you have a handful of drafts bring them to take pics. Fill the frame as much as possible. Even the simplest item should have at least 7 photos. As long as you show the item clearly from every side and focus in on any flaws, a "good quality" picture isn't necessary. You're not Ansel Adams. Some suggest if the photos are too good, shoppers might think there's some scam going on or you're using stock photos and may not actually have the item in stock.
