Add query string on PPC ad that appends to Marketo form as hidden field

[Anonymous]

Our PPC vendor is currently driving traffic to our main website (not to a specific PPC landing page/form). We are able to see leads that enter the site via PPC and converted by filling out a web form (as we've added code onto all of our success pages). However we are not able to track this back to a particular lead without manually matching the time stamps of the PPC conversion to the time a lead submitted that particular form.
 
Our PPC vendor wanted to know if we can add a query string from our PPC ads and append/pass that data to the marketo form they use on our site, as a hidden field. This would allow us to see that “john smith” clicked through from a PPC ad and submitted the form -- allowing us to report on PPC ROI.

Has anyone done something like this before? We are currently in testing mode with this vendor, but when we reach volume we'll absolutely need automation to know which lead came via PPC (ie through a hidden field, which would update their lead source to PPC).

Thank you!

Yes, you can definitely do this.

Define which fields should be appended via the hidden form:

Lead Source
AdID
AdGroup
Keyword

etc

Then use a url parameter creator to help you keep track of it all.

The Form you can add any field and make it Hidden, tell it to be dependent on the URL Parameter = X.

There are some great discussions on this if you look for url parameters.

Hey Kate,

This article has instructions on how to set up your form to do exactly this: https://community.marketo.com/MarketoArticle?id=kA050000000LH7uCAG

Susana Moreira​, I can look up that old doc if you really need it, but I already have another new one I wrote a little while back that gives all of the same details. Tracking Lead Sources

Thank you Josh and Kenny for the incredibly fast replies. I think I have all I need. Have a great weekend!

What happens if the same lead responds to more than one PPC campaign - won't this just capture their most recent response as the old data would be overwritten?
