/case/ - Case Studies

I'm looking at this idea of moving the email input to the very top of the checkout flow. I don't see how we can tell if it actually helps conversion without a long run. It's probably just a seasonal fluke in traffic volume. I need to see some actual data on field completion time before I believe it does anything.

The order of the other fields is a huge confounder here. If you don't keep everything else exactly the same, we won't know if the change worked or if people just got distracted by something else. We should run this for at least two full weeks to account for weekend behavior.
