1.69% non-active to 2.78% active
The 50/50 A/B test
One audience. Two experiences.
For 12 Mondays (May 4, 2026 to July 20, 2026), live traffic on every McLarty dealership was split into two groups. Roughly 39% of visitors got Speed Layer Active. The rest did not.
Same sites. Same ads. Same inventory. Same shoppers. The only variable was whether Speed Layer was on.
That makes this a clean A/B test. The cohorts shared identical conditions except one: speed. When the faster cohort consistently converts better across 28 rooftops and 12 weeks, the signal is hard to dismiss.
