What Marketing Numbers Should a Law Firm Owner Look At Every Month?

Most law firm marketing reports fail in the same way. They are twenty pages long, they arrive a two weeks after month end, and the owner skims the first page and files it. Nobody is at fault — the agency produced what was asked for. It just does not support a decision.

An owner does not need everything measured. They need the smallest set of numbers that, taken together, would change what they do next.

The six

Total marketing spend. Everything: media, vendor fees, retainers, production, tools. Firms routinely underestimate this because it sits across several invoices and several vendors. A number that only counts ad spend understates the real figure, often substantially.

Signed cases. Not leads, not inquiries, not consultations. Cases the firm took. This is the output the spend exists to produce.

Cost per signed case. Total spend divided by signed cases. Blunt, and deliberately so. It is the one figure that connects what went out to what came back, and the direction it moves over a year says more than any channel breakdown.

Share of cases with a known source. What percentage of signed cases have a recorded origin. This is the trust indicator for every other number in the report. If it is low, the channel analysis underneath is unreliable, and an owner should know that before acting on it.

Speed to first contact. How long between an inquiry arriving and a human speaking to them. This is the stage where most firms lose most of the cases they will lose, and it is almost entirely within the firm’s control.

Average case value. Because cost per signed case is meaningless without it. A falling acquisition cost alongside falling case value is not an improvement, and it is a pattern that can run for a year before anyone notices.

Why those and not others

Each one, if it moved sharply, would prompt an owner to do something.

Spend rising without cases rising prompts a conversation about where. Cost per case climbing prompts a look at which channel. Unknown-source share falling prompts an intake process fix. Speed to contact slipping prompts a staffing decision. Case value drifting down prompts a conversation about case mix.

Compare that with impressions, bounce rate, or keyword position. Those explain things. They do not, on their own, prompt an owner to act — and they belong to the person managing the channel.

The two most firms are missing

Almost every firm can produce spend and signed cases. The two that tend to be absent are unknown-source share and speed to contact.

They are absent for the same reason: neither belongs to marketing or to intake cleanly, so neither team reports it. Marketing does not see what happens after the inquiry arrives. Intake does not think of response time as a marketing number.

They are also the two with the most recoverable value. A firm that raises its known-source share can finally trust its channel decisions. A firm that improves speed to contact usually finds cases it was already paying for and losing.

If you add only one number to your reporting this quarter, add speed to first contact. It is the cheapest thing to fix and the most expensive thing to ignore.

How to look at them

On the same axis, every month. Same six numbers, same order, same definitions. The moment the report changes shape, comparison across periods stops working.

With at least a year of history. Case volume in personal injury is lumpy. A slow month is not a trend, and a strong month is not a strategy working.

Segmented only when something moves. Keep the top-level view to six. When one of them changes materially, go one level down and find out why. Building the diagnostic detail into the monthly report means nobody reads either layer.

What this replaces

Most firms already receive several reports — one per vendor, each in a different format, each claiming credit within its own channel. None of them can answer the owner’s actual question, which is whether the whole thing is working.

The point of a short list is not that detail is unimportant. It is that an owner reviewing six numbers every month will notice a change, and an owner skimming twenty pages will not.

Before the numbers can be trusted

Two prerequisites, in this order. Every inbound contact has to be captured somewhere, regardless of channel or hour. And a lead record has to carry through to the case record, so a signed case can be traced back to where it came from.

Without the first, the denominator is wrong. Without the second, the source data is guesswork. Firms that skip these and go straight to reporting end up with a tidy dashboard built on numbers nobody can defend — which is worse than no report, because it invites confident decisions on unreliable information.
