Case Study | Top Personal Injury Firm in a Top 5 DMA
How a top PI firm grew case volume +20% and dropped cost per case −10%.
Decades of broadcast advertising had carried the firm this far, but the precision they needed to grow more cases at a lower cost was not something broadcast could deliver.

Client

Market
A top 5 U.S. media market
Heritage
Decades of broadcast-led legal advertising
Goal
Grow case volume while lowering the cost behind every case
The Problem
Broadcast was producing cases.
It just wasn’t producing them efficiently enough to keep growing.
The firm relied heavily on broadcast television and templated campaigns to drive case acquisition in one of the largest U.S. media markets. Three things made that strategy harder to scale: market fragmentation made it difficult to reach the audiences that actually mattered, competitors moved quickly to mimic the firm’s messaging, and broadcast offered no way to know which campaigns were producing signed cases.
They needed performance data, not impression counts, to keep growing case volume without rising cost. They needed a partner who would build the campaign around their specific firm rather than apply a template that competitors could copy.
The Results
Case volume grew 20% while the cost behind every case dropped 10%.
Most campaigns force a tradeoff between volume and efficiency. This one moved both metrics in the right direction at the same time.

Why It Worked
Three things made the difference.
Partnership
An embedded extension of the firm’s marketing team, not a vendor handoff.
Precision
Audience-first targeting in the moments people actually need a PI attorney.
Dual lift
More cases and lower cost per case at the same time, which is the harder result to deliver.
