For e-commerce value based custom audiences is a MUST! Here's how to set your up: • Go to audiences section • Create custom audience and select "website traffic" • Change the dropdown from URL to Event (make sure Advanced Mode is turned on) • Choose the Purchase Event • In the optional parameters box choose "value" • Type in whatever value you want, in this case I did over $100 in purchase value but you can specify any value you want • Choose your audience time window and save it!
