Stop reporting cost per lead. Start reporting cost per signed case.

Cost per lead is the most misleading number in legal marketing. Here's why it drives bad budget decisions, and what it takes to replace it.

Ask most firms what their marketing costs and you will get a cost-per-lead figure. Ask what a signed case costs to acquire, by channel, and the room usually goes quiet. That gap is where a great deal of legal marketing budget quietly goes to die.

Why cost per lead misleads

Cost per lead treats every inquiry as equivalent. It is not. A form fill from a broad-match keyword and a phone call from a high-intent local search convert at wildly different rates and produce matters of wildly different value. Optimizing toward the cheaper of the two is a rational response to the wrong metric.

Worse, ad platforms optimize toward whatever you tell them to. Feed Google a form submission as your conversion event and it will get very good at producing form submissions — including from people whose matters you would never take.

Why the number is hard to produce

Not because the maths is difficult. Because the data sits on two sides of a wall. The ad platform knows the click; the intake system knows what the matter became. Connecting them requires that someone own both, and in the standard arrangement — agency on one side, firm's own CRM on the other — nobody does.

• The agency cannot see which leads signed, so it optimizes on what it can see
• The firm cannot see which channel produced a signed matter, so it cannot challenge the report
• Both parties are behaving reasonably and the number still never gets produced

What closing the loop looks like

1. 01Every lead source is tagged at the point of capture, including phone calls.
2. 02Intake records what the matter became — consultation booked, retainer signed, declined and why.
3. 03Retainer outcomes flow back into the ad platforms as offline conversions.
4. 04Reporting shows cost per consultation and cost per signed case, by channel and by practice area.

This is the reason the Attract Engine and Intake OS are the same engagement here. Attribution that reaches the retainer requires owning both halves — which is also why we are not a marketing agency.
