The Challenge
Legal services advertising is highly competitive, especially in practice areas like family law. Early campaign efforts produced leads, but costs fluctuated and results were inconsistent.
The firm needed a strategy that could:
-
Increase lead volume over time
-
Reduce cost per lead
-
Deliver consistent performance rather than peaks and valleys
-
Adapt to predictable seasonal shifts without losing efficiency
The Approach
Instead of relying on one-time optimizations, we implemented a long-term, iterative testing strategy across Google and Meta campaigns.
Key elements of the approach included:
-
Ongoing A/B testing of messaging, creative, and audience signals
-
Using every test to inform future improvements, not just short-term decisions
-
Developing new “challenger” ad elements based on proven high performers
-
Allowing campaign platforms to learn and optimize using increasing volumes of high-intent data
This process ensured the campaigns continually improved rather than plateauing as time went on.
The Results
Over a two-year period, the campaigns evolved into a reliable and highly efficient lead generation engine.
Lead Growth
-
Daily lead volume increased steadily from early 2024 through 2025
-
By year two, the firm was consistently generating 3–5+ leads per day
-
Lead growth was sustained, not driven by short-term spikes
Cost Efficiency
-
Cost per lead dropped significantly as the campaigns matured
-
Early costs in the $20–$40 range were reduced to single-digit and low-teens CPLs
-
Efficiency remained stable even as lead volume increased
Consistency & Predictability
-
Campaigns showed expected seasonality during holiday periods, with brief dips in volume
-
Performance rebounded quickly each year as demand normalized
-
By late 2025, results were predictable enough to support confident planning and budgeting
Industry Context: Legal Advertising Benchmarks
Cost per lead in legal marketing is typically higher than in many other industries due to competition, urgency, and the potential value of each case.
For family law and trusts & estates firms, it’s common to see:
-
$75–$200+ per lead in competitive markets
-
Higher CPLs in metro areas or during peak demand periods
Because a single retained case can represent significant lifetime value, success is measured less by the lowest possible cost and more by lead quality, consistency, and predictability.
In this case, the campaigns significantly outperformed typical legal benchmarks by delivering qualified leads at substantially lower costs while maintaining steady volume over time.
Why It Worked
The success of this campaign was driven by discipline and consistency, not shortcuts. Rather than chasing trends or resetting strategies, we focused on:
-
Continuous learning from real performance data
-
Building on proven insights instead of starting over
-
Refining messaging to better align with high-intent prospects
-
Scaling only after efficiency was established
As the system gathered more data, the platforms became smarter, costs stabilized, and lead quality improved.
“Since working with the HIG Digital Marketing team, we’ve seen a steady increase in qualified inquiries while our cost per lead became far more predictable.”
