Personal Injury Marketing: How to Plan the Spend and Know What Worked

Most personal injury marketing budgets are set one of two ways. Either the firm spends what it spent last year with an adjustment, or it spends what it believes a competitor is spending. Neither of those is a budget. They are both guesses wearing a spreadsheet.

The awkward part is that the number which should set the budget is one most firms cannot state on demand: what it currently costs them to sign one case. Not to buy a lead, not to book a consultation. To sign. Until that number exists, every other marketing decision is being made in the dark, and the firm has no way to tell an expensive channel from a profitable one.

This article is about the money and the measurement rather than the channels. If you are still deciding which channels to run, the channel by channel breakdown covers that ground, and the build it or buy it question is worth settling first. What follows assumes you are spending already and want to know whether it is working.

Start from cost per signed case, not cost per lead

Cost per lead is the number everybody quotes because it is the number everybody can calculate quickly. It is also the number that hides the most. Two channels can deliver leads at the same price and differ by a factor of three in what they cost you per signed case, because the leads convert at completely different rates.

The calculation you want is straightforward and most firms already have the inputs. Take everything you spent to acquire cases in a period, including the retainer you pay an agency and the salary of anyone whose job is marketing, and divide it by the number of cases signed from those efforts in that period. That is your blended cost per signed case.

Then do it again per channel. The blended figure tells you whether the programme works. The per channel figures tell you what to do next, and they are usually where the surprise is. Firms routinely discover that the channel they were about to cut for having a high cost per lead has the lowest cost per signed case in the account, and that the cheap channel they were proud of signs almost nobody.

Once you have that number, the budget question stops being philosophical. If a signed case is worth a known average fee to you and costs a known amount to acquire, the correct budget is however much you can spend while that gap stays comfortably positive and your intake can still handle the volume.

What the budget actually has to cover

The spend line that firms plan is usually just media: the ad budget, the agency fee, the cost of leads. The spend that actually determines the result includes several things that never make it onto the marketing budget at all.

Intake capacity is the big one. Every acquisition channel assumes somebody answers, follows up and keeps following up. A firm that buys more volume than its intake can work is not buying cases, it is buying a larger pile of unreturned calls, and the cost per signed case rises even though nothing about the marketing changed. If you are adding budget, the honest version of the plan says who is going to work the additional volume.

The second is the tracking itself. Call tracking numbers, a CRM that records source on every matter, and somebody whose job it is to keep the source field accurate. This looks like overhead until the first time you try to decide between two channels and find you cannot, because half your matters are attributed to a source called other.

The third is the creative and the landing pages the traffic arrives on. Sending better traffic to a page that does not convert is the most expensive mistake on this list, and it is invisible in a media report that only counts clicks.

Fast money and slow money belong on separate lines

Personal injury acquisition splits cleanly into things that produce cases this month and things that produce cases next year, and the two need to be budgeted and judged separately. Mixing them into one marketing number is how firms end up cancelling the slow thing during a quiet quarter and starting again from zero eighteen months later.

Paid search, local service ads and purchased leads are fast. Spend goes in, enquiries come out, and both stop when the spend stops. You can turn these up or down in a week, which makes them the right tool for a capacity gap and the wrong tool for building anything durable.

Search visibility, content and reputation are slow. They take months to move, they compound, and they keep producing after you stop paying. The three assets inside an SEO line item behave differently enough from each other that even this category needs splitting once you are spending seriously on it.

A reasonable working split is to fund the fast channels to whatever your intake can absorb, then commit a fixed slow money line that you agree in advance not to raid. The agreement matters more than the exact percentage, because the slow line is always the one that looks optional in the month you need cash.

Why last click attribution misleads in personal injury

Attribution in this practice area is genuinely hard, and the standard tools are built for a shorter and simpler buying journey than the one your clients actually take.

Somebody is in a collision. They ask a relative. They look at two or three firms online over several days. They read reviews. They go quiet for a week because they are dealing with an insurer and a car. Then they search your firm by name and call. Last click attribution records that as a branded search, and the channel that genuinely introduced them gets nothing.

This produces a specific and predictable distortion: branded search and direct traffic look extraordinarily efficient, and everything upstream looks wasteful. Firms then cut the upstream spend, watch branded search volume fall a few months later, and struggle to explain why.

Two practical corrections. First, ask every signed client how they heard about you and record the answer, even though a meaningful share will say they cannot remember. It is imperfect and it still catches things the analytics cannot see. Second, watch branded search volume as an output rather than an input. If your name is being searched more, something upstream is working, whatever the attribution report says about it.

The lag is the hardest part to manage

The gap between spending the money and knowing whether it worked is long enough to break most review cycles. A lead arrives, intake works it over days or weeks, a case gets signed or does not, and the fee arrives a year or more later. Judge a channel in month one and you are judging lead volume, which is not what you are buying.

The way through this is to pick a milestone early enough to measure and late enough to mean something. Signed cases is usually the right one. It is far enough down the funnel to reflect lead quality and close enough to the spend to review quarterly.

It also means accepting that a channel needs a fair trial. Cutting after three weeks because the cost per lead looked high tells you nothing about whether those leads would have signed. If you cannot commit to running something long enough to see signed cases from it, that is a reason not to start it rather than a reason to start it and stop early.

What to review monthly, and what to leave alone

Reviewing everything every month is how good channels get killed by normal variance. Split the review by how fast the underlying thing can actually change.

Monthly is for the operational numbers: spend against plan, lead volume, how fast intake is responding, how many enquiries went unreturned, and whether anything has broken. Response time belongs here because it is the one variable you can fix this week and it moves conversion more than most media decisions do.

Quarterly is for the money questions: cost per signed case by channel, which channels are worth more budget, and whether the slow money line is showing early signs of life. These are the decisions with real consequences, and they need enough signed cases behind them to be worth making.

Annually is for the structural question of whether the mix is right at all, and whether the practice areas you are buying are still the ones you want to be in.

The questions worth asking before you sign anything

Whether you are hiring an agency, buying leads or bringing something in house, the same small set of questions separates a proposal you can evaluate from one you cannot.

What exactly am I buying, and is it exclusive to my firm. How is a lead defined, and what happens to one that turns out to be outside my practice area or my state. What will be reported to me, how often, and does it include anything past the click. What is the term, and what does leaving look like. Who owns the assets and the data if we stop working together.

The exclusivity question is worth particular attention in personal injury, because shared and exclusive leads behave so differently that comparing their prices directly tells you almost nothing useful.

A provider who answers these plainly is not necessarily the cheapest. They are the one whose performance you will be able to judge, which over a year is worth considerably more.
