Here's an example of how we're currently tracking lead source (utm_source) and lead source details (utm_medium) through the various channels for a white paper we want to promote:
Email: xyz.com/marketing-test.html?utm_medium=whitepaper&utm_source=email
Web: xyz.com/marketing-test.html?utm_medium=whitepaper&utm_source=web
Facebook: xyz.com/marketing-test.html?utm_medium=whitepaper&utm_source=facebook
How would I track the source and details for a banner ad that we want to promote on a 3rd party website or on multiple 3rd party websites?
xyz.com/marketing-test.html?utm_medium=whitepaper&utm_source=bannerad
I feel like this doesn't full capture everything because we want to know which 3rd party website generated the conversion.
