How we unnecessarily burned 20k with Facebook Ads
I wanted to call this out:We solved the first problem through a separate tool, which labels the user with the originating source when registering.Yes, yes, yes, and  yes. If you're spending any significant amount of money on advertising, you need to be doing this. Don't rely solely on third-party cookies and session unification attempts. If you have a USER table in your database/crm, add the five UTM fields to it! Conversions for most businesses are a multi-day and, often times, multi-device process.
