I'm not sure what their strategy was if any, but we didn't see any noticeable increases with other leads, engagement or contact methods. Our website referrals tanked since May for the group, see the snapshot below from ATC backend reporting (green line on right) on a dealership with no changes to ATC in the given time-frame. Our dual analytics attribution shows a 67% drop in ATC referrals too from June to July.
I appreciate the inside look at the analytics. Curious as to what your daily inventory level is? How many vehicles do you have listed on Autotrader?
