This is a controversial area for many on eBay. But I was given specific direction and reasoning by this eBay employee.
He stated that items begin to go stale after only 90 days. He hinted that items appear dormant after 180 days. The only way to combat this is to end the item, REWORK the item and then list it again. The key is to REWORK the item before listing it again.
Do NOT simply end and re-list. Use AI to rework the title and description as well as make changes to the Item Specifics and price. Then list the item again.
This was something that my son and I were already doing and have been seeing results. We are now more aggressive with the practice by ending items quicker than before. This is now something we do as part of our daily routine. Items no longer become stale as we rework them before they are 180 days old.
