orders property
Orders is the total number of purchase conversions you received attributed to your ads.
How it works: You report conversions with cart data for completed purchases on your website. If a conversion is attributed to previous interactions with your ads (clicks for text or Shopping ads, views for video ads etc.) it's counted as an order. Example: Someone clicked on a Shopping ad for a hat then bought the same hat and a shirt in an order on your website. Even though they bought 2 products, this would count as 1 order. This metric is only available if you report conversions with cart data.
