Question
UTM Parameters as Hidden Fields - not coming through
I included hidden fields to capture utm parameters for forms within Marketo landing pages that we're driving traffic to through paid search. But, I'm getting quite a few blank sources coming through. Anyone know why that may be?
I'm also receiving quite a few default ("no source", as an example). Thoughts on what % of overall form fills I should expect to see blank and default values?
Thanks!
