You can use your Average Order Value to check for acquisition performance.
Say customers acquired via your Shopify Online Store have an AOV of $100, Facebook Ads $95, and Amazon $75. That makes it really easy to compare the channels e.g. compare their costs vs value.
If you also measure the Repeat Purchase Rate by channel you can see how likely it is that those customers come back and buy again. That'll help decide if a slow channel catches up in the long-term.
In Repeat Customer Insights your acquisition channel performance is measured in several metrics and compared across time.
