How much does a sales rank tell me about the likelyhood of a product selling? If one EAN has a sales rank of 40,000, but another EAN for the same item with a more detailed title / description has a sales rank of 145,000 do I have far less chance of selling it with the second EAN? I would have thought that a more detailed title would be the better EAN to sell under?
Also, is it possible that an EAN with no current items for sale under that listing might have had a much better sales rank a few months back when there were some active listings? That is to say does the fact a product / EAN has no current items listed under it automatically demote its sales rank.
