how to promote my other listings on my ebay listings

They'll just show your normal listing in its normal spot. But, if the people who rank above you are willing to pay too (or if their listings are just way better than yours), then eBay won't give you those higher rankings.

If you offer to pay enough, they'll rank you in spot #2 or even #1. Say you're trying to sell dumbbells and your listing normally ranks #3 in searches for 'dumbbells.' You decide to promote the listing. The next time someone searches for 'dumbbells,' eBay will consider how much you're willing to pay before putting you back in spot #3. You're essentially bribing eBay to put you above the competition. The normal rules of eBay SEO still apply, but promoted listings rank higher than normal listings. What makes them worth paying for is the search ranking. The only real difference is the word 'Sponsored.' If you change your listing, the change will appear in your ad as well. In a standard search, they basically work like any other listing. They’re the listings that appear as “ Sponsored” all over eBay. Here’s how they work and when to use them. But if you don’t understand them, you could do more harm than good for your profits. While many kinds of ads can waste your money, these are well worth the cost in most situations. Should you use eBay’s promoted listings? The answer is incredibly simple: yes!
