I have a gorgeous bag that i want to sell on ebay.
The designer is fairly unknown though so i doubt many people would search by the designers name so im just wondering the best way to list the bag in order to get the most exposure to buyers and searchers?
It depends on how high volume of a seller you are. If you normally list a lot of items or will be listing other items with this one, you might get enough hits just because people check out one of your auctions, then clicks "see seller's other auctions".
I'd also look at the completed auctions for this brand. You never know, some brands have a following and people obsessively look for them on eBay. I recently sold a pair of shoes from a relatively obscure brand but had 50+ watchers and a ton of bids because I feel like all the same people search for that brand and collect them.
If neither of these are the case (you are a low volume seller and completed auctions aren't high/there aren't even any completed auctions!) then I'd consider an alternate route like a consignment shop. eBay is all about getting a lot of people to your auction, so if you can't, there's no use going through all the trouble IMO.
I love "discovering" different designers on EBay. Hope you have great luck. I would still put the designer name in the title, but more importantly, use all of the descriptors accurately. I sometimes do look only by color or type or whatever. That is how I found the Camuto bag I carry. I would not have known to look for the brand.
