The business group that you’ve linked to your Merchant Center account contains more unique Business Profiles than your local product inventory feed. Make sure all your Business Profiles have complete inventory data.
Benefits
If you provide inventory data for all your locations, your local products will show in ads and free listings for users shopping nearby. Well-timed ads and listings help drive more traffic to your retail location.
How to find locations with missing data
Compare the list of store codes in your Business Profile Manager to the store codes in your local product inventory feed. If there are Business Profiles with missing inventory data, add the data to your local product inventory feed.
