It would be great to create a funnel report that compares the different conversion rates by a given property.
For instance: Funnel report by Original Source with made up numbers:
MQL > SQL | SQL > Opp. | Opp > Customer | |
Paid Search | 50% | 20% | 10% |
Organic Search | 60% | 30% | 15% |
Paid Social | 45% | 15% | 5% |
Organic Social | 60% | 20% | 2% |
etc. etc...
As I can tell, the only way to do this is to set up INDIVIDUAL funnel charts and set the filter of "Original source" = Paid search (and change this per funnel chart).
