Presenting inventory

McCarthy Chevrolet Lee’s Summit wanted to promote the dealership's current inventory and pricing to shoppers who are in the market for a vehicle and then measure the return on ad spend.


Reaching active car shoppers again

McCarthy Chevrolet Lee’s Summit partnered with automotive advertising agency Omni Advertising on this campaign to find new customers and to show ads to people who had previously viewed specific vehicles in stock.

To look for new customers, the team showed automotive inventory ads to specific zip codes and cities around the dealership near Lee’s Summit, Missouri, and to a lookalike audience based on its current customer list. To create the ads, the team uploaded a catalog of its inventory and installed the Facebook pixel on its website to provide information about visitors’ activities there.

The automotive inventory ads then used the information from the pixel to show people vehicles they had previously looked at online, helping to bring these shoppers to the next phase in the vehicle buying journey. The ads appeared in a slideshow format, showing multiple vehicles and prices. Video ads showed several angles and the exterior and interior of one vehicle.

Reaching people who are actively shopping for cars online, and are more likely to buy, helped increase the dealership’s return on ad spend. To further increase returns, the team also selected campaign budget optimization to automatically distribute budget across the campaign's ad sets based on their performance.

Finally, to measure and verify the results of the ads, the team used Facebook’s offline conversions measurement solution and uploaded sales data from the dealership's customer database to Facebook Ads Manager. Facebook matched up the sales information to people who engaged with the ad campaigns to show how many purchases came from which ad sets.

The automotive inventory remarketing works very well. The metrics usually look great on these ads, but now seeing the sales with offline conversions, it further proves that inventory remarketing is a best practice for converting traffic back to sales.

Facebook’s offline conversions is an awesome way to measure the success of our ad campaigns. Previously we had to estimate results, but now we know for sure how many customers are actually exposed to and engaging with our ads. Measuring vehicle sales through offline conversions really helps us understand what is in demand and what resonates with different audiences.
