Google has announced a set of stronger requirements for certain important fields. Google's blog post announcing these changes is available here. We have outlined the changes below and strongly recommended that anyone who is active on Google Product Search takes the time to make sure their feed is up to Google's new standards.
These new standards are well in line with what SingleFeed has long recommended and following them will improve your feed quality across all shopping engines.
GOOGLE'S NEW REQUIRED FIELDS
UPCs (Unique Product Identifiers)
Starting May 3, Google will require unique identifiers for all products except apparel and one-of-a-kind items. Products without unique product identifiers may not be listed in Google Product Search. What this means is that you will need to provide a UPC, ISBN (books) or the combination of an MPN (manufacturer part number) and Brand. All SingleFeed merchants are already providing the Brand attribute to Google because we map our required Manufacturer field to Google's Brand field. If you are unsure what any of these fields are, please review Google's instructions here and SingleFeed supported fields here. If you already provide UPCs or MPNs for all products in your feed no action is needed, but we do encourage you to double-check that they are valid identifiers.
If unique identifiers are unavailable for your products, you can file an exception request with Google.
Tax & Shipping
Starting June 6, Google will begin requiring tax and shipping information. There are two ways to provide Google with this information:
1. Set account-level default values in your Google Merchant Center account: These preferences will serve as the default values for all of your items. This is the easiest way to set up tax and shipping for your account.
2. Include item-level override values in your data feed: These values will override your account-level default settings for that item.
Please review detailed instructions through here. SingleFeed supports Google's new Tax field as well as Shipping Weight and Shipping fields. We recommend providing Shipping Weight in the feed (if available) and setting the rest of the shipping and tax rules through the Google Merchant Center interface.
GOOGLE'S NEW RECOMMENDED FIELDS
Google is adding support for Sale Price, which of course is a familiar field to most merchants. SingleFeed is already mapping our Sale Price field to Google's new Sale Price field and no action is needed from merchants who provide this information in their feed.
Sale Price Effective Date
Google is also introducing a new field called Sale Price Effective Date, which SingleFeed now supports. This field is used to specify the date range during which the sale price applies. You will find this field in your SingleFeed file or you may add it to your feed with the exact name: Sale Price Effective Date.
You can find detailed information about both of these fields here.
