Have a fairly large number of product pages on an ecommerce site that rank well in Google but we sell very few of the items and each year it diminishes a little more as Amazon grabs more and more of the business. These are first page rankings, usually below Amazon, then perhaps the manufacturer, sometimes followed by another retailer, then us. I'm trying to determine whether I should leave them or delete. The cost to leave them is minimal but I would prefer to concentrate my efforts on the items/pages that do sell.
This is a seasoned site which was hit hard by the first Panda. What would you do? Am I better off in Google with 1000 products/pages of which 100 products sell, or 100 product/pages?
