I've attempted to setup a campaign that tracks the referring URL to a Marketo landing page using a UTM to track the original source. So the path would be: Clicks Twitter Advertisement that has UTM: http://www.godigitalmarketing.com/learn/blog/brand-building-how-to-turn-a-negative-review-into-a-positive-branding-strat?utm_source=twitter&utm_medium=social%20&utm_campaign=BB16Q2 They land on our blog page, if they click the C2A at the bottom of the page they are redirected to a marketo landing page that has a hidden referrer field in the form: Then I have a campaign set to trigger off of the UTM source in the URL (If referrer contains "twitter" then lead enters campaign flow) This is not working currently and I feel like I am missing something big, or don't understand something important about UTMs... HELP!

Hi Thomas,I just ran a test.I used first Brand Building: How to Turn a Negative Review into a Positive Branding Strategy - G/O Digital MarketingThen I clicked the "download ebook" link at the bottom, I got here: Building Blocks For Your Online BrandLooking at the form, I see the hidden leadsource field with the value "twitter", so the capture of the referrer parameter to the hidden field works as expected.So you could try to use the "fills out form" without the constraint but with a "lead source = twitter" filter.Now, your own trigger should work-Greg
