Case Study: DEL Grande Dealer Group achieves deeper marketing attribution and cost savings with Marchex

Revolutionizing Automotive Digital Marketing with Marchex Solutions

DEL Grande Dealer Group, the Bay Area’s largest family-owned automotive group with 19 retail locations and 17 brands, faced fragmented marketing attribution, a critical GA4 launch, and complex CRM integration needs. They engaged Marchex to remove marketing blind spots and implement call-tracking and attribution capabilities (including Dynamic Number Insertion and GA4 event integration) to better capture customer intent across locations.

Marchex deployed a DNI-based call-tracking and attribution solution, integrated call-event data into Google Analytics 4 and the dealer’s CRM, and enabled multi-touch attribution with partners like Clarivoy, real-time call outcome labeling, and ad-platform feeds. As a result, Marchex gave DEL Grande Dealer Group session-level visibility into callers and outcomes, closed the sales loop by attributing leads back to campaigns, reduced wasted ad spend, and improved ROAS through more accurate, data-driven marketing decisions.
