The short answer
A dealership that connected its CRM and DMS data to LinkOne grew monthly leads by 25% in nine months, and 35% of the vehicles it sold were verified as influenced by its advertising. Sold VINs were matched to the buyer and to the ads that buyer saw, using privacy-safe UID2 identifiers.
The 35% is an attribution measure: vehicles sold to buyers who had seen the advertising. It is not a measure of incremental lift.
Which ads actually sold cars?
Dealership data sits in separate systems: the CRM, the DMS tools and the ad platforms. That makes it hard to see which impressions or campaigns led to a vehicle sold.
Without those systems working together, this dealership couldn't optimize toward the numbers that matter, like cost per verified sale or impressions per car sold.

Questions about this case study
- What results did the dealership get from connecting its CRM and DMS to LinkOne?
- Within nine months, monthly leads rose 25% and 35% of vehicles sold were verified as influenced by advertising, a 7x improvement in visibility into what drives car sales.
- How does LinkOne connect ads to vehicle sales?
- LinkOne matches the buyers in your DMS or sales file to their ad exposure, then identifies the vehicles they purchased. You can see which campaigns reached those buyers, even without an ad click.
- What if our DMS can't be connected?
- A vehicle sales file can support sales matchback when a direct DMS connection isn't available. Without a DMS connection or sales file, you can still run campaigns and receive standard reporting, but we can't verify vehicle sales against ad exposure. We'll confirm your options during setup.
