Short links give us all an organic view, rather than a direct view, which helps with our search visibility within Etsy.
To post a short link, copy the link for your item. When pasting, make sure to erase everything from the end of link until the end of the 9 or 10 digit unmet after the "listing" portion of the link. For example, see below;
