I've read that in Collectibles, (and a couple other categories) that recency of listing is the most important best match factor and that instead of re-listing or using GTC, unsold items should be re-submitted as "sell similar" so it gets launched as a new listing. But this has to be done on a single listing basis, correct? If I use a profile to re-list an item, does it launch as a new item or just as a re-list? With hundreds of items ending every day or so, the time involved to re-list each one as a "sell similar" is nuts. Any suggestions?
