Stop Reporting Traffic: Cost Per Signed Case Is the Only Metric That Matters

What is cost per signed case?

Cost per signed case is your total marketing spend on a channel divided by the number of retained clients that channel actually produced. Not clicks, not calls, not form fills — signed retainers. It is the only marketing number that belongs in the same conversation as your firm’s revenue, and most agencies never show it to you.

Why don’t most agencies report it?

Because it requires accountability at every step of a chain most agencies do not control — or do not want measured. To compute cost per signed case you must track a click to a call, a call to an intake, and an intake to a retainer, then tie that retainer back to the channel that started it. Every step is a place for wasted spend to hide. Traffic reports have no such problem: traffic always goes up somewhere.

How do you actually measure it?

The chain looks like this, and each link is a solved problem:

1. Call tracking and form attribution tag every inquiry with its source —

organic, Local Service Ads, PPC, Google Business Profile, referral.

2. Intake integration ties inquiries to your CRM so unqualified contacts

and duplicates fall out of the count.

3. Retainer matching connects signed cases back to the originating source.
4. Channel math: monthly channel spend ÷ signed cases from that channel.

If your agency says this is impossible, they are describing their own program, not the state of the art.

What does the number change?

Everything. Real examples of the decisions cost per signed case forces:

• A channel producing cheap leads and expensive cases loses budget to a channel

producing fewer, better inquiries.

• Local Service Ads often sign cases at a fraction of paid-search costs — but

only when the profile, reviews, and responsiveness are managed. The number tells you when they are not.

• Organic search looks expensive in month three and looks like a bargain by

month eighteen, because content compounds while ad prices only rise. The number is how you prove the compounding to a skeptical partner.

What should a Personal Injury firm target?

There is no universal benchmark — case values differ too much between a rear-end settlement and a trucking verdict — and anyone quoting you a single industry number is selling something. The honest approach: establish your baseline across every channel in the first ninety days, then force each channel to beat it. Across our portfolio, disciplined attribution plus monthly rebalancing has consistently pushed the share of new cases sourced through digital past half of all new business.

The uncomfortable question to ask your agency

Ask them: “What did a signed case cost me, by channel, last quarter?” If the answer is a traffic chart, you have an activity report, not a marketing program. Your marketing deserves the same scrutiny as any other investment the firm makes — that is not a metaphor, it is the whole method.
