Personal injury is the practice area where the gap between a lead and a case is widest, and where it closes fastest. People who have just been in a collision are frightened, often in pain, and frequently calling three firms in the same sitting. The one that answers wins a disproportionate share of them.
Which means the most expensive failure in a personal injury account usually is not the account. It is a call that rang out at six in the evening, a callback attempted the following morning, or an intake conversation that treated an urgent caller like an enquiry. We instrument that whole chain, because there is no point lowering cost per click while the end of the funnel leaks.
You can win the auction and still lose the case in the ninety seconds after the phone rings.
