Personal Injury Lawyer Marketing That Bids on Signed Cases
Accident-case leads cost more than almost anything else in legal advertising. We run Google, Meta and Microsoft Advertising for PI firms spending $100K+ a month, and judge every dollar by the contingency fees it brings in.
What a Personal Injury Lead Costs on Local Services Ads
Most agency pages list channels without a price. Here is what Local Services Ads produced for a personal injury firm we manage over three months, August to October 2026.
| Measure | Result |
|---|---|
| Leads received | 164 (calls and messages) |
| Leads Google billed | 116, or about 7 in 10 |
| Cost per lead, all leads | About $395 |
| Cost per billed lead | About $560 |
A billed lead is still not a client. The number that decides whether the channel pays is how many billed leads sign. With a target cost to sign a case of $3,000, a firm paying $560 per billed lead needs about 1 in 5 of them to sign. Below that rate, Local Services Ads cost more than the case is worth to the firm.
That sign rate is the first thing we measure, because it depends as much on intake as on the ads.
How Google Decides Which Injury Leads You Pay For
Local Services Ads charge per lead, not per click, and Google checks every lead when the prospect first makes contact. Leads it judges invalid or low quality are never charged.
Not charged
Leads Google rejects at first contact, plus duplicates. They still appear in the account, which is why the firm above received 164 leads and paid for 116.
Credited later
Charged leads are reassessed over time, and some are credited back automatically. Credits usually reach the account balance within 30 days, while the original charge stays on the invoice.
No longer credited
Google stopped crediting leads for a case type the firm doesn't take or a location it doesn't serve. Case categories and service area now have to be set exactly, because those mistakes are billed.
Before any of this, every attorney at the firm passes Google's screening, including a check of each state bar license. Rating each lead in the account's feedback survey keeps the record straight and can earn a small credit.
Bidding Search on Contingency Value
Search and Performance Max can bid on value, but a contingency fee arrives months or years after the click. So each signed case goes back to Google Ads on the day it signs, with an expected fee attached.
Case types don't carry the same expected fee. A rear-end auto claim, a catastrophic injury and a wrongful death matter are worth very different amounts to the firm, so each case type the firm signs carries its own value. Bidding then shifts budget toward the searches that produce the larger cases, without anyone splitting campaigns by hand.
The signed case is the event that matters, but it is rare. Qualified calls and booked consultations feed the bidding in between, so the account has enough data to learn from while cases are still being signed. Our guide to offline conversion tracking covers how those events reach Google.
Reaching People Right After an Accident
Video ads on smart TVs and YouTube reach people whose recent searches suggest an accident, an insurance claim or a comparison of injury firms. Few of those viewers call from the ad itself.
Inside Google Ads, video campaigns often show almost no conversions. We judge them instead by what follows: more searches for the firm's name, more calls from brand search and more signed cases in the weeks after a flight runs. Short follow-up videos on phones keep the firm in front of viewers who didn't act the first time.
Seasonal pushes, such as a Halloween flight, run under the same rule. They earn more budget only if signed cases rise.
Why Most Injury Leads Are Lost at Intake
An accident victim calls several firms and signs with whoever answers and takes the case seriously. A missed call after hours is usually a case signed by a competitor.
We track every ad phone number, so each call is tied to the campaign and search that produced it. Short calls, wrong numbers and solicitors never count as conversions, so the bidding doesn't learn to buy more of them. How that works is in our guide to Google Ads call tracking.
Intake results go into the same reports as ad spend. When the sign rate drops, the fix is often an intake script or staffing change, not a bid change.
Advertising Rules for Personal Injury Lawyers
ABA Model Rule 7.1 bars any false or misleading communication about a lawyer's services, including a true statement that misleads because it leaves out a material fact. Most states base their own rule on it.
State versions add their own requirements, from disclaimers to filing ads with the bar for review, and they differ widely. Every ad, landing page and intake script we write follows the firm's state rules, and none of them promises a result or a settlement amount.
What Injury Firms Ask Before Hiring an Agency
Is Local Services Ads worth it for a personal injury firm?
Usually, if intake can sign enough of the leads. Divide your cost per billed lead by your target cost per signed case: that gives the share of billed leads you need to sign to break even. Track that rate monthly, because it moves with your intake team as much as with Google.
How much should a personal injury firm spend on Google Ads?
Enough for the bidding to learn. A campaign needs roughly 50 conversions in a rolling 30 days, so at about $560 per billed lead, Local Services Ads alone would need around $28,000 a month. Firms below that level learn more slowly and pay for it in higher costs.
Can catastrophic injury and wrongful death cases be targeted separately?
Yes. Each case type gets its own value, so the bidding can favor the searches that produce higher-value matters. Local Services Ads also let the firm choose which injury categories it accepts leads for.
How do you measure TV and YouTube ads for a law firm?
By what happens after a flight runs, not by clicks. We compare brand searches, brand calls and signed cases during and after each flight with the weeks before it, and keep the budget only where signed cases rise.
Do you work with personal injury firms in any state?
Yes, anywhere in the US. Campaigns follow the advertising rules of each state the firm practices in, and Local Services Ads run only where the firm's attorneys hold an active bar license.
