How much do personal injury lawyers spend on advertising?

SEO questions · Personal injury attorney SEO

Short answer

Anything from a few thousand dollars a month for a small local firm to millions a year for the firms on billboards, and there is no reliable public figure for the average. The more useful number is cost per signed case by channel. Published data puts a paid search lead at roughly two and a half times the cost of one from SEO.

Personal injury firms are among the biggest advertisers in local markets, which is why the question comes up so often. But most of the figures quoted online about what firms “typically” spend come from agencies with something to sell, and they rarely say how they were measured. So I will tell you what can be supported, and how I would think about the budget instead.

Why there is no good average

Spend depends on three things that vary enormously between firms: the market (a small city against Los Angeles or Miami), the case mix (car accidents against catastrophic injury or mass torts), and the firm’s model (a two-attorney practice against a volume firm with an intake team). An average across all of those would describe nobody.

What can be measured is the cost of each enquiry and each signed case, by channel. That is the number a budget should be built from.

What leads cost by channel

The most specific public data I know of comes from First Page Sage, which reported personal injury cost per lead across 49 firms in 36 states over 2022 to 2024: $442 from Google Ads, $378 from Local Services Ads and $183 from SEO. First Page Sage is an SEO agency and this is its own client data, so treat it as directional rather than neutral. It matches the shape I see in practice.

For context across legal advertising more broadly, WordStream’s benchmarks put the median legal cost per click at $9.87 and cost per lead at $131.63 across 13,474 US campaigns. Personal injury sits far above those medians. Competitive injury terms routinely cost $150 to $300 a click in most markets, and more in the largest metros.

Where the money usually goes

Paid search and Local Services Ads. Fast, measurable, and the largest digital line for most firms.
TV, radio and outdoor. Brand building for firms large enough to sustain it. Hard to attribute, and it drives branded searches that then show up in search channels.
Purchased leads. From lead vendors. Variable quality, often sold to several firms at once.
SEO and content. Slower to start, cheaper per lead once working, and it keeps producing after spend stops.

How to set your own budget

Start from the value of a signed case to your firm, after costs. Then work out your current cost per signed case by channel, which means tracking leads through intake to signed retainer rather than stopping at the form fill. A channel that produces cheap leads that never sign is expensive.

Then decide what you are buying time for. Paid search buys cases this quarter. SEO buys cheaper cases next year and the year after. Most firms that do well run both: ads for the near term, search building underneath so that each year a larger share of cases arrives without a per-click charge. I wrote about the economics in the cheaper number behind a $442 lead.

The leak most firms do not measure

Intake. A firm can spend heavily on advertising and lose a large share of the resulting calls to slow response, voicemail after hours or a receptionist who does not recognise a good case. The MIT lead response research found a twenty-one-fold drop in the odds of qualifying a lead between a five-minute and a thirty-minute response. In injury law, where the person is calling several firms, the effect is likely stronger. Fixing intake is the cheapest increase in advertising return available.

What a sensible split looks like for a smaller firm

A firm without a television budget cannot outspend the large advertisers in its market, and should not try. The places a smaller firm can compete are narrower: the map pack in its own part of the metro, practice area pages for the case types it actually takes, service area pages for the places it genuinely serves, and paid search focused on those same case types and areas rather than on the broadest, most expensive terms.

That focus matters more than the size of the budget. Spreading a modest ad spend across every injury term in a large city usually buys a handful of expensive clicks on everything and a strong position on nothing. Concentrating it buys visibility where the firm can win.

What to measure every month

Three numbers, by channel: enquiries, signed cases, and cost per signed case. If you only measure the first, you will keep paying for channels that produce calls you never sign. If you measure all three, the budget usually decides itself within a quarter.

Most firms that start tracking this way cut at least one channel within six months and move the money somewhere it signs more cases.

If you want more of your cases to come from search instead of paid clicks, my SEO for personal injury law firms starts with the map pack, practice area pages and your intake, in that order.
