Buy Legal Leads: Treat the First Purchase as a Test, Not a Bet

Firms that buy legal leads for the first time almost always make the same mistake, and it has nothing to do with choosing the wrong supplier. They buy a small batch, work it unevenly for two weeks, sign nobody, and conclude that bought leads do not work. Then they try a different supplier and repeat it.

The problem is that the first purchase was never designed to answer a question. It was a small bet with no defined size, no defined duration and no agreed measurement, so whatever happened afterwards could be read any way the reader was already inclined to read it.

This article is not about which supplier to choose. That is a separate question with its own checklist, and it is worth working through first. Nor is it about whether to buy at all rather than build the channel in house. This is about the mechanics of the first purchase itself, once those two decisions are made.

What you are actually buying

You are not buying cases. You are buying attempts, and a rate. Every purchased lead is a chance to reach somebody who raised their hand, and the only thing that matters commercially is what share of those chances convert and what each signed case ends up costing.

That framing matters because it tells you immediately that a single lead carries almost no information. If one in fifteen leads signs, then the first fourteen leads signing nobody is the single most likely thing that can happen. It is not a warning sign. It is the expected result.

How many leads before the number means anything

This is the part firms skip, and it is the part that decides whether the test can work at all.

If a realistic sign rate is somewhere around one in ten to one in twenty, a batch of ten leads cannot distinguish a good campaign from a bad one. Zero signings out of ten is entirely consistent with a campaign that would have produced a perfectly acceptable rate over a hundred. So is two signings out of ten, in the other direction. A small batch does not give a weak answer, it gives no answer, and the firm that reads one anyway is reading noise.

Before you buy, work out roughly how many leads you would need to see before the result would change your mind, and buy at least that many or do not start. For most injury firms this lands in the low hundreds rather than the dozens, spread over enough weeks that the intake team is not overwhelmed in the first three days.

If that number is more than the firm is willing to spend, that is a genuinely useful finding. It means the honest answer is not yet, rather than a test that was always going to be unreadable.

The budget to put at risk

Decide the whole number before the first lead arrives, and treat it as spent. Not a monthly commitment you can cancel in a huff halfway through, and not an open tap. One defined amount, agreed internally, that the firm can lose entirely without anybody needing to justify it afterwards.

This is what stops the two failure modes. A firm with no defined ceiling keeps going long past the point of learning anything, because stopping feels like admitting a mistake. A firm with no defined floor stops on week two after a bad run and calls it a conclusion.

What to measure, and what to ignore

Four numbers, agreed in advance, all of them recorded per lead rather than remembered in aggregate:

Contact rate. What share of leads you actually spoke to. This is mostly a measure of your own speed and persistence, not of lead quality, which is exactly why it has to be separated out. A campaign cannot be blamed for people your office called once on day three.

Qualification rate. Of the people you reached, what share matched the criteria you set. This is the number that genuinely evaluates the supplier.

Sign rate. Of the qualified, what share retained. This mostly evaluates your intake and your follow up.

Cost per signed case. The only number that decides whether to continue. A high cost per lead with a high sign rate beats the reverse every time, and firms routinely get this backwards by shopping on lead price.

Splitting the first three is the whole point. A firm that tracks only signings cannot tell a supplier problem from an intake problem, and will confidently blame the wrong one. Most practice management systems will record this if somebody decides the fields in advance, and there is a wide range of tooling built for exactly this kind of pipeline tracking if the existing system will not.

The terms that make a test possible

Three things belong in writing before the first lead, and all three are ordinary asks that a serious operator will not object to.

Written qualification criteria. States, case types, injury threshold, how recent the incident, whether the claimant has already retained counsel. Without this, every later disagreement is an argument about adjectives.

A return or credit mechanism. What happens to a lead that is plainly outside the criteria, with a defined window for raising it. This is not about clawing back money, it is about having a shared definition of a miss.

A pause right. The ability to stop delivery at short notice if intake capacity disappears. Leads arriving into an office that cannot work them are worse than no leads, because they produce a bad result that then gets blamed on the campaign.

Where most first purchases actually fail

It is rarely the leads. It is the follow up, and it fails in a way that is invisible from the inside because every individual decision looked reasonable.

A lead is called once, goes to voicemail, and is marked as no answer. Nobody calls back the next morning, or the evening after that, and the record quietly dies. Meanwhile the firm is forming a view about lead quality based on people it never spoke to.

A first purchase needs a written follow up sequence that runs regardless of how anyone feels about it, and somebody who owns it. The discipline involved is ordinary lead nurturing practice pointed at an intake queue, and applying it is usually the single largest improvement available to a firm that thinks bought leads do not work for them.

Speed matters here more than almost anything else, and the minutes after a lead arrives do most of the work.

When to conclude

At the end of the agreed volume, not before, and against the four numbers rather than a general feeling. Three outcomes are available.

Continue. Cost per signed case is inside what a case is worth to the firm. Scale carefully and keep measuring, because the rate that held at a hundred leads does not automatically hold at a thousand.

Fix the intake and retest. Qualification rate was fine and sign rate was poor. That is your problem, not the supplier's, and switching supplier will reproduce the result exactly.

Stop. Qualification rate was poor against criteria that were written down and agreed. That is a supplier answer, and it is a clean one, which is the entire reason for writing the criteria down first.

The honest summary

Buying legal leads is not a gamble, but it is routinely run as one. Size the purchase so the result can be read, decide the money before you start, measure the four rates separately, and agree the criteria in writing so that a disappointing month produces a finding rather than an argument. Firms that do this usually get an answer on the first attempt, whichever way it goes. Firms that do not tend to buy from four suppliers in a year and never learn anything from any of them.
