Case Study: Carter Jonas achieves clear call attribution and higher-quality inbound leads with Infinity Tracking

How the Property Consultancy Increased the Rate of Qualified Inbound Calls by 10.4% as they Navigated an Ambitious Period of Growth

Carter Jonas is a long-established, multi-disciplinary UK property consultancy with almost 40 branches and over 700 staff. The firm was receiving thousands of inbound calls a month—about 65% of its leads—but had no attribution visibility, and its rapid expansion (locations doubled over three years) meant it urgently needed a scalable way to understand what was driving enquiries at each location.

Infinity implemented visitor‑level call intelligence and flexible segmentation by location, region and channel, tracking every digital touchpoint down to the keyword. As a result Carter Jonas saw a 10.4% rise in quality calls, a doubling of calls from referral sites, a 9.7% increase in PPC-qualified leads and a 50% drop in missed inbound calls; they are now connecting their CRM to Infinity to further measure marketing ROI.
