Alex, reading the questions from your survey above - is this a 2 part question? Take the survey and also list your favorite overall metric, no matter the metric?
If I'm an ISM paid on lead to sale, the answer is conversion.
If I'm a forward thinking dealer principle, I want VDP views. All. Day. Long.
More VDP views can equal more online form leads but it's also going to increase phone calls and more importantly, foot traffic.
When are we going to quit being so lead centric and focus on the experience, effortlessly leading the customer right through the showroom door?
Bonuse: a vehicle with a shit load of VDP views and no action is telling you something.
Online Lead conversion alone is a "blind" metric.
