The challenge

A personal injury firm wants more viable motor-vehicle matters without increasing irrelevant calls.

What WKND built

Ad groups by buyer question: Representation process and firm fit (50% or $45,000); Consultation preparation (30% or $27,000); Attorney comparison and service information (20% or $18,000).

Landing page

Use an attorney-led page with service area, matter types, representation process, authentic credentials, and a clearly explained consultation. The initial form should ask only what routing requires. Send case documents and detailed incident information through secure intake. Explain any actual fee arrangement accurately rather than using an invented settlement promise.

Intake and follow-up

Provide live routing during staffed hours, a clear after-hours process, consented follow-up, appointment reminders, and an attorney handoff. Log qualification reasons and engagement status. A booked intake is not a signed case; a signed case is not a fee recovery.

The lesson

The scenario can produce attractive expected case economics and still consume cash for months. Sell the intake and measurement discipline alongside acquisition. The future fee figure is probability-weighted planning value, not 90-day ROAS.
