You might sell red boots online but not blue ones, Google will now show you the products you don't sell that you might be able to easily sell and reach more customers.
The new report is called the Shopping Assortment Report which will list the top 100 products that you don't already offer in your Merchant Center product feed for each Google Product Category.
Here is a screen shot of what the report looks like:
The report shows you:
- Identify key products that are missing from your feed. Identify popular products you do sell, but may have forgotten to include in your data feed, or may have the incorrect GTIN associated with the product.
- Expand your product offerings. Identify popular products you currently do not sell, but may wish to source from suppliers and add to your product feed.
