UTM best practices?
Are there any downsides to putting UTM values into custom fields to retain this information with a lead? I'm using embedded forms on our site (no landing pages yet) and hidden fields with custom fields for the UTM values.
I'm also following some discussions about passing the UTM values into cookies so it's not lost if a conversion doesn't occur and the users comes back to convert in a subsequent visit. That's of interest down the road a bit.
