About data mapping across feeds
Local inventory ads show shoppers what nearby stores have the products they're looking for. To surface this information, Google matches data across the 4 possible sources for local inventory ads: Google My Business Locations, the local products feed, the local product inventory feed, and the products feed.
Data mapping between the online products feed and the local products feed only occurs if you are using a legacy local products feed.
About matching
The key links between all of your data submissions are your product identifiers and your store codes. These attributes must be consistent across all of your data sources.
As a starting point, we grab the unique ID for a product that matches a shopper’s search query. Depending on how you set up your feeds, this ID is at least one of the following:
-
idin your products or local feed and/or -
webitemidin your local products feed
Using the product ID, we grab information about that product from your products feed (if applicable), local products feed, and local products inventory feed. Then, we use your store code to gather information about the store where that product is sold.
