Client account cross-sell units sold is the total number of products sold as a result of advertising a different product.

How it works: You report conversions with cart data for completed purchases on your website. If the ad that was interacted with before the purchase has an associated product (see Shopping Ads) then this product is considered the advertised product. Any product included in the order the customer places is a sold product. If these products don't match then this is considered cross-sell. Cross-sell units sold is the total number of cross-sold products from all orders attributed to your ads. Example: Someone clicked on a Shopping ad for a hat then bought the same hat, a shirt and a jacket. The cross-sell units sold in this order is 2. This metric is only available if you report conversions with cart data.
