Case Study: Stoneacre Motor Group achieves tripled PPC sales calls and 21.1% higher average order value with Infinity Tracking (Smart Match)

How did the automotive dealership group use Smart Match to triple PPC sales calls while boosting AOV by 21.1%

Stoneacre Motor Group, a multi-dealer automotive group, faced a clear challenge: they couldn’t reliably connect PPC-driven calls to revenue or identify which audiences and campaigns (notably Performance Max) were generating high-intent leads. With variable buying cycles and no call-to-revenue attribution, marketing and sales couldn’t optimise spend or accurately track outcomes.

Using Infinity’s Smart Match and integrating call-conversion data into Google Analytics 4 and Performance Max, Stoneacre tied calls back to specific vehicles and revenue to measure true cost-per-sale. The solution tripled PPC sales calls (+300%), increased average order value from PPC by 21.1%, improved the PPC clicks-to-calls ratio by 79%, and delivered precise, actionable attribution for better targeting and campaign optimisation.
