Using the SellerChamp View Summary feature, once the items have been added to a manifest, our systems can break down items according to their sales rank in a graphically representation.
In regards with the time it will take to sell items on the basis of their sales rank, in essence, lower the sales rank the faster item will sell along with what category it has been listed within and it's price, but in general the sales rank breakdown is as follows:
Less than 100 - very popular and fast selling (edited)
Less than 5000 - popular
Less than 25000 - will sell if price right
Less than 50000 - might sit for a while before selling
