Which campaigns produced matters that actually paid?

Legal marketing is measured at the top of the funnel because that is the only place anything is countable quickly. Cost per lead, cost per consultation, cost per signed matter. All three are available within days, and none of them is revenue.

The revenue arrives when the matter resolves. For a transactional practice that might be weeks. For personal injury it is commonly a year or more, and the fee depends on a settlement nobody could predict at intake. So the campaign that produced a case is scored long before anyone knows what the case was worth.

Matching collected fees back to the client removes the timing problem entirely. The client who called in March 2025 and whose fee was collected in July 2026 is one match, and the campaign running in March 2025 is credited with the fee. There is no window to expire and no model to trust.

In most practice areas the spread between an ordinary matter and an exceptional one is enormous, and the exceptional ones carry the year. Ranking channels on signed matters treats a routine case and a career case as one each.

Ranking on collected fees does not. A channel that produces fewer but larger matters moves to the top, which is where it belongs and where no lead-based report will ever put it. This single change is the most common reason a firm's channel ranking inverts.

Legal intake happens on the phone. A prospective client searches, clicks, reads for ninety seconds and calls. The form, where one exists, is a fallback. That means the conversion the ad platform records — if it records one at all — is a call event with no outcome attached.

A call tracking export supplies the caller's number and the campaign; Clio supplies the fee and the client's number. Those two files join on the number, which is why this segment reconciles unusually well. Firms that already run call tracking usually get a high match rate on the first upload.

A firm running family, criminal and personal injury work has three different buying cycles, three different fee structures and three completely different advertising markets. A blended cost per client across them is not a number anybody can act on.

A practice area column splits the report so each can be funded on its own evidence. For multi-office firms, an office column does the same thing on Growth and above.

A personal injury or mass tort practice will get almost nothing useful from twelve months of data, because the fees collected this year came from matters signed one to three years ago. The first upload should be three years wherever contingency work is a meaningful share of revenue.

That sounds like a burden and is usually not: the export is the same report with a wider date range. What it changes is the quality of the answer — with three years the report can show which channels produced the cases that actually resolved, which is the only version of the question a managing partner cares about.

Transactional practices are the opposite. Estate planning, immigration and family work resolve fast enough that twelve months is genuinely sufficient.
