This page shows results for an identical product to the one on our other “food processor” page, but we get the results in a different, theoretically more accurate way, using a UPC – a universal product code: 883049249285.
UPCs are a standardised way of identifying specific products and if the product data providers have supplied UPCs then they can be very useful for getting the exact results we want!
Just remember that they can sometimes be more trouble than they are worth, if not all retailers are using them properly. There are also many variations of the same product with different UPCs. Also, products will get discontinued eventually and your page stop showing any results – but that can happen anyway!
All in all, product codes are an extremely accurate way to do product comparison!
