This might not be what you did, Bill, but I've seen something similar many times. And I'm guilty of what I'm about to say, too... so many times
We all get excited about the new shiny thing and give it special placement on our site, but it doesn't get the results we wanted. Technologists come up with a new way to do something, and it doesn't get the engagement they wanted. After seeing and doing this as a dealer and in different tech companies, a simple lesson has been learned:
Don't fuck with customer expectations.
If CTAs are in the same places on consumer sites, mimic that. If a customer searches for a car via drop-downs on most consumer sites, mimic that. It is easy to forget car shoppers are car shoppers once every few years. They are grocery shoppers, electronics buyers, Amazon browsers multiple times a month/week. When you introduce something different, you confuse and frustrate people. I know, this is an excitement killer, but when you're doing something different, it never hurts to have "Plain Jane Boring Plan B."
P.S. This post is mostly for future Alex and developers he is talking to.
