Is there a public benchmark for cost per signed case in legal?

Not an audited one. Figures circulate, but they vary enormously across practice areas and almost never state what was counted as a case or which costs were included. The number worth acting on is your own, calculated the same way each month, compared against your own prior quarters.

What schema type should a law firm use to mark up its services?

LegalService identifies the firm, Attorney identifies each lawyer, and FAQPage marks question blocks so they can be lifted cleanly. Those three plus BreadcrumbList cover almost every firm. Our structured data for AI search page carries the field-level detail and the mistakes that invalidate the markup.

Can I compare my firm to a competitor using only public data?

On visibility, yes: rankings, reviews, publishing cadence, citations in AI answers and link profiles are all observable for any domain. On economics, no. Intake conversion, cost per signed case and case value live inside their systems, and any competitor figure for those is an estimate wearing a benchmark's clothes.

Do legal industry reports include marketing performance benchmarks?

Mostly not at channel level. The Clio Legal Trends Report, the Thomson Reuters State of the US Legal Market and the ABA Legal Technology Survey Report concentrate on rates, utilisation, collection and technology adoption. Where client acquisition appears, it is usually discussed in general terms rather than as cost per case by channel.

How much data do I need before a benchmark means anything?

It depends on signed case volume, not elapsed time. A firm signing a handful of cases a month will see month-to-month swings that are pure noise, so quarters are the smallest honest unit. A high-volume practice can read monthly movement. Match the reporting period to the volume, not to the calendar.

Does publishing structured data improve our benchmark numbers?

Indirectly at most. Markup makes your services legible to search engines and assistants, which can affect visibility, and visibility eventually shows up in your own performance data. It produces no comparative numbers by itself. The two senses of the phrase meet there and nowhere else.

Who offers structured data for benchmarking legal services?

By Mohammad Kashif, Chief Technology OfficerLast updated September 21, 2026

Two things share that phrase: schema markup that labels legal services for machines, which you publish yourself, and comparative performance data, which no vendor sells as an audited legal benchmark. The usable version is built from your own records.

One question sorts the real offers from the rest: how many firms are in the sample, and over what period? The published legal benchmarks that can answer it, such as the annual Clio Legal Trends Report or the Thomson Reuters State of the US Legal Market, measure practice economics rather than marketing channel performance.

Do you mean schema markup, or comparative performance data?

The phrase gets typed by two people with almost nothing in common. One is a marketer or a developer looking for the vocabulary that labels a legal service so a machine can read it: what the service is, who provides it, where it is offered, what it costs. The other is a firm owner looking for numbers to sit beside their own, so they can tell whether their own cost per signed case is good, bad or normal for their practice area.

The first sense is settled and cheap. The types are public, free to publish, and applied to your own pages rather than bought from anyone. Nobody sells it as a dataset because it is not a dataset, it is a labelling standard. If that is what you came for, the implementation reference is our page on structured data for AI search, linked at the foot of this one.

The second sense is the hard one, and the answer is less satisfying. There is no audited, comparable dataset of law firm marketing performance on sale. What exists is a set of partial sources, each measuring something real, none of them interchangeable, and most of them describing your own firm rather than anyone else's.

Where does law firm benchmarking data actually come from?

Every number a firm could benchmark comes from one of six places. Knowing which one a figure came from tells you immediately what it is allowed to prove. The table further down adds a seventh, a vendor's own client base, which is the one source you cannot inspect and the one most benchmark claims quietly rest on.

Google Search Console, for impressions, clicks and average position per query. First-party, free, and the cleanest demand signal you own. It says nothing about any other firm.
Your analytics platform, for sessions by channel through to a form submission. This is where channel comparison starts, and it is why we keep pointing firms at the analytics setup guide before anything else.
Your intake and case management records, which are the only place a signed case exists as a fact rather than an estimate. The denominator of every meaningful marketing number lives here, not in a marketing tool.
Call records, because real leads arrive by phone and never touch a form. Without them the channel picture is systematically wrong, not just incomplete.
Market-level keyword and ranking data, which is genuinely comparable across firms because it is measured the same way for everyone. The catch is that search volume is reported nationally, so a state or metro figure only exists where the query itself names the place.
Published industry reports, which are the closest thing to a real benchmark in legal. The Clio Legal Trends Report, the Thomson Reuters State of the US Legal Market and the American Bar Association's Legal Technology Survey Report are the recognised ones, and all three centre on practice economics rather than channel-level marketing cost.

What has to match before two firms' numbers can be compared?

A benchmark is a comparison, and a comparison requires that both sides counted the same way. This is where most legal marketing benchmarks quietly fall apart, because the definitions are never stated and they are never the same.

Six things have to agree before a number from another firm means anything next to yours. A benchmark that does not state all six is a number without units.

What counts as a lead. Form fills only, or calls and chats too? Are repeat callers deduplicated? A firm counting every inbound call and a firm counting only qualified consultations are not reporting the same quantity, whatever both of them call it.
What counts as a signed case. Retainer executed, matter opened, or fee collected? In contingency work these can be months apart and the choice moves the number more than any campaign will.
What is in the cost. Media spend alone, or media plus agency fees plus the intake salary answering the phone? The same campaign yields wildly different cost per case depending on where that line is drawn.
The attribution model and window. Last click and multi-touch will disagree about which channel earned a case, and a lookback window shorter than the time your matters take to sign will drop them entirely.
The time basis. Cases signed this month are rarely the cases this month's spend produced. Comparing spend and signings inside the same calendar month flatters fast practice areas and punishes slow ones.
Practice area and market. Immigration, criminal defence and mass tort do not share a cost structure, and a national average across all of them describes no actual firm.

Can you benchmark against competitors without seeing their numbers?

Partly, and the split is clean. Everything on the visibility side of the funnel is externally observable, because it is published. Everything on the economics side is not, and never will be.

You can compare, without anyone's cooperation: ranking positions for the queries you both want, review counts and average ratings, publishing cadence and topical coverage, how often each of you is named in assistant answers, indexed page counts, and the profile of sites linking to each domain. These are measured identically for every firm, which is what makes them comparable at all.

You cannot compare intake conversion rate, cost per signed case, consultation show rate or case value, because those numbers exist only inside another firm's systems. Anyone presenting them as a competitor benchmark is modelling, not measuring, and the model's assumptions are doing all the work.

Price is the partial exception, because some of it is published. Our own entry plan is $599 a month, on a public pricing page anyone can open and check. Most agencies publish nothing, so the $4,000–$10,000 a month band we use for a single-channel agency scope is our own benchmark for the category, not a surveyed market figure, and it is labelled that way wherever we cite it. A claim about what firms typically earn back is neither published nor benchmarkable, which is why you will not find one on this page.

What should you ask a vendor selling legal benchmarks?

The category attracts confident round numbers. The questions below are the cheapest way to find out whether there is a dataset behind one.

Applied to ourselves first: LexGrow does not publish an industry benchmark drawn from its own client base. A book of clients small enough to name individually produces case studies, not a benchmark, and presenting it as one would fail the first two questions below. What LexGrow sells instead is the structuring work that makes a firm's own comparison hold: one definition of a lead, one definition of a signed case, costs assigned the same way every month, and the observable side measured against named local competitors.

The last question is the one that ends most benchmark purchases honestly. For a firm signing a modest number of cases a month, the only comparison where the definitions are guaranteed to match is against its own prior quarter.

How many firms are in the sample, and over what period were they measured?
Are those firms in my practice area and my market, or is this all of legal averaged together?
How do you define a lead and a signed case, and does that match how my intake actually records them?
Is the cohort fixed between periods, or does the sample change each time, so movement could just be churn?
Which figures come from firms' own systems, and which are estimated from public data?
What can this tell me that my own quarter-over-quarter trend cannot?

What each source can benchmark, and where it stops

Source	What it measures	Comparable to other firms?	Where it stops
Google Search Console	Your impressions, clicks and average position per query	No, first-party only	Silent on everything after the click
Analytics platform	Sessions by channel through to form submission	No, first-party only	Ends at the form, not at the signed case
Intake and case records	Leads, consultations, signed cases, case value	Only if definitions are shared and identical	The only place a signed case is a fact
Call records	Phone leads tied back to a source	No, first-party only	Needs the source captured at ring time
Market keyword and ranking data	Position and estimated demand for any domain	Yes, measured the same way for everyone	Volume is national unless the query names the place
Published industry reports	Practice economics: rates, utilisation, adoption	Yes, at industry level	Rarely broken out by marketing channel
A vendor's client base	Whatever that vendor happens to measure	Only within that vendor's book of clients	Sample size and definitions usually undisclosed
