Source Attribution for Twitter

[Moriah_Diedrich]

I'm trying to set up a source tracking campaign for my company's Twitter ads.

Here is our Smart List:

...and our Flow (which we use to track Person Source in Salesforce):

The campaign isn't tracking any members even though we know that multiple people have clicked the ad and filled out the form.

Any ideas why the campaign isn't tracking people based on the smart list and flow above?

Is Marketo just not a feasible place for attribution tracking things like Twitter, LinkedIn, etc.?

Am I wasting my time trying to get this campaign to work?

Thanks in advance!
