Behind the transformation

How a Florida PI Firm Signed 4 Cases in One Week of ChatGPT Ads

Personal injury is one of the most expensive categories in paid advertising, and costs climb every year. This Florida firm wanted an edge, so Rankings.io launched it on ChatGPT ads as an early adopter, with a small test budget aimed at its highest-value auto accident cases. The result: 4 signed cases in the first week, on less than $115 in spend.

FROM CHALLANGES TO SUCCESS

How the Firm Started: The Challenge

Personal injury is one of the most expensive categories in paid advertising. Firms compete for the same clicks on the same mature platforms, where costs climb every year and a single case can cost hundreds or thousands of dollars to acquire. 

This Florida firm wanted an edge: a way to win new cases where they did not have to bid against competitors.

At the same time, AI answer engines began to open up advertising, creating a genuine first-mover opportunity. The catch was uncertainty. The channel was brand new, with no established benchmarks and no proof that AI-platform traffic would actually convert into signed cases rather than just clicks.

The firm needed a way to test the opportunity without betting a large budget on an unproven strategy.

How We Did It: The Strategy

Rankings.io treated this as a controlled experiment with a clear goal: find out, fast and cheaply, whether a brand-new AI advertising channel could produce signed cases. We created a strategy to move first, start lean, and measure success by cases rather than clicks.

1. Experiment Early With an Emerging Channel

Rather than wait for ChatGPT ads to become crowded and expensive, we launched the firm onto the channel as an early adopter. Being first meant less competition, lower costs, and a chance to learn the platform before the rest of the market caught on.

2. Start Lean With a Controlled Test Budget

We kept the initial spend deliberately small so the firm could validate the channel with minimal risk. A tight budget also forced discipline, putting every dollar behind the firm's highest-value case type.

3. Target the Firm's Highest-Value Case Type

We focused the campaign on auto accident cases, the firm's priority practice area, and pointed traffic to a dedicated, conversion-focused auto accident landing page built to turn visitors into consultations rather than just views.

4. Test Multiple Creatives and Measure by Signed Cases

We ran multiple ad variations to learn what resonated on the new platform, then judged performance by the only metric that matters: signed cases. This kept the experiment honest and proved the channel on real business outcomes, not vanity metrics.

Before & After

The experiment paid off almost immediately. Within the first week of launching on an entirely new advertising channel, the firm signed four new cases, all on a tiny test budget.

The real win was bigger than four cases. The firm now has early proof that AI advertising can deliver signed cases at a fraction of the cost of saturated channels, and a head start on a platform its competitors have not yet discovered. An experiment became a repeatable new source of cases.

Key Wins

  • 4 signed cases in the first week from a brand-new ChatGPT ads channel
  • Under $115 in spend to sign those cases, under $30 per signed case
  • $11.73 average CPC at a 0.66% click-through rate
