We’ve been advised by Shopping.com that they are changing the number of mandatory fields for products from 3 to 9 with effect from 1st July 2010. These are now all required for a feed:
Image (Minimum size 150 x150 pixel)
MPN or UPC (certain products only)
No massive showstoppers for most e-store owners as these are fields which are almost universally contained within an e-store by product. MPN might present a problem if you don’t have the data, although this only affects products in Consumer Electronics and/or Media.
If you are already a Feed Manager customer this need not be a concern; your shopping.com feed will be updated in line with their new listing instructions.
However, if you are submitting a feed to shopping.com independently, you’ll need to take action in the next couple of weeks to prevent problems with your listing.
