averageOrderValueMicros property
Average order value is the average revenue you made per order attributed to your ads.
How it works: You report conversions with cart data for completed purchases on your website. Average order value is the total revenue from your orders divided by the total number of orders. Example: You received 3 orders which made $10, $15 and $20 worth of revenue. The average order value is $15 = ($10 + $15 + $20)/3. This metric is only available if you report conversions with cart data.
