The Core Challenge & Bottleneck

Inbound property buyers and sellers submitted website inquiry forms but waited an average of 4 hours for human reps to call back. By that time, over 70% of prospects had already contacted competitor firms or failed to answer the phone. The client was burning $12,000/month in PPC advertising with a miserable 4% lead-to-appointment conversion rate.
