The data wheel sends data back and forth, allowing you to track and automate pretty much anything. Popchef created Facebook ads with a CPC of less than 0,04€ by retargeting users who added meals to their cart and left without buying anything. The good news is you can pretty easily hack it with other tools like Zapier, Webhooks, write Keys and simple Urls, without being a programmer.
