Here is what each advertising channel actually costs, what it actually produces, and how to build an advertising system you can measure.
A PI firm owner in Phoenix called me to review his advertising spend. He was running $18,000 per month in ads across TV, Google, and Facebook. When I asked which channel was producing the most signed cases, he paused for a long time before saying he thought it was Google but was not sure. That pause is the entire problem with how most PI firms approach advertising. The spend is real. The results are guesses.
The American Tort Reform Association published data showing that legal services advertising now costs $3.2 billion per year in the United States. Personal injury makes up the largest share of that by a significant margin. The category has grown every year since 2017 and showed no sign of slowing through 2024.
That money is being spent. The question is whether it is being measured. Most PI firms run advertising across two or three channels simultaneously, use a single phone number across all of them, and have no system that ties a ringing phone to a specific ad, platform, or campaign. When they sign a case, they record that the client called. They do not record which channel produced the call.
Bo Royal at Pareto Legal calls this the attribution problem, and it is the root cause of most wasted PI advertising spend. Without attribution you cannot cut what is not working or scale what is. You end up spending more across all channels hoping the aggregate produces more cases, which it sometimes does, without telling you anything useful about what to do next.
The fix is not complicated. Every advertising channel needs its own tracked phone number or dedicated landing page so that every call and every form submission can be attributed to a source. This is not optional. It is the minimum infrastructure required to make any advertising decision with actual evidence.
Personal injury attorney advertising runs across five main channels in 2026. Understanding what each costs, what each produces, and when each makes sense prevents you from spending money in a channel that is wrong for your firm size or market.
Google Search Ads. The highest-intent channel available to PI firms. The person clicking your ad just typed car accident lawyer near me or personal injury attorney Houston. They are not browsing. They need a lawyer right now. The cost per click ranges from $80 to $300 in most mid-sized markets and can exceed $500 in metro areas like Los Angeles, New York, or Miami. A starting budget of $1,500 to $3,000 per month will produce meaningful data in most markets outside the top 10. The critical variable is what happens after the click. A Google Ad landing on a homepage that takes no action converts at 1 to 2 percent. A quiz funnel on the same traffic converts at 6 to 12 percent. The ad spend is the same. The cases are not.
Google Local Service Ads. LSAs appear above regular Google Ads. They carry the Google Screened badge, show your reviews directly in the listing, and charge per lead rather than per click. For most PI firms they represent the best cost per lead available in Google's ecosystem because the pay-per-contact model removes the risk of paying for clicks that never convert. The limitation is that LSA budgets are capped and Google controls how leads are distributed. LSAs should run alongside Google Search Ads, not replace them.
Facebook and Meta Advertising. Facebook does not capture demand. It creates it. The person seeing your Facebook ad was not searching for a lawyer. They were scrolling. This means Facebook requires different creative than Google. Educational content, video, and quiz-style hooks outperform direct offers because they meet the user where they are rather than where you wish they were. The cost per click on Facebook is lower than Google, often $5 to $25, but the cost per signed case is similar or higher because conversion rates are lower and the lead qualification process is longer. Facebook works best for PI firms that have their follow-up system built out, because many Facebook leads require multiple touchpoints before signing.
Connected TV and streaming advertising. CTV spend in the legal category grew 241 percent between Q1 2023 and Q4 2025 because it solves the geographic targeting problem that made traditional TV expensive for smaller firms. You can run a 30-second spot on Hulu or Peacock targeted to adults 35 to 65 within a specific ZIP code who have recently searched for legal services. Minimum budgets are lower than broadcast television and attribution is more trackable through landing page URLs shown on screen. This channel makes sense for firms ready to build brand recognition in a defined geographic market alongside their digital performance advertising.
Traditional broadcast television. At sufficient scale and with proper call tracking, broadcast TV can work for PI firms. The problem is scale. TV requires frequency to move. A viewer who sees your ad once does not call. A viewer who has seen it twenty times over six weeks might. That frequency requires budget. Most PI firms running broadcast TV are spending less than the threshold required to achieve meaningful frequency in their market. The exception is regional firms running $20,000 or more per month on television alone with dedicated tracked numbers for each market.
Every advertising channel delivers one thing: a lead who made contact. What happens after that contact is what determines whether you sign the case or lose it to the firm that followed up faster.
Research published in the Harvard Business Review found that following up with a lead within five minutes makes you 100 times more likely to convert them than following up at 30 minutes. In PI, where someone has just been in an accident and is calling multiple firms, this window is not five minutes. It is often two or three.
Most PI firms do not have a system that calls a lead back within five minutes unless a staff member happens to be free when the lead comes in. Advertising spend produces leads. The absence of an immediate follow-up system loses them to a competitor who answered first.
This is the sequencing principle that determines whether advertising produces cases or just produces activity. Build the follow-up system first. Confirm that it calls every lead within seven minutes, every day including weekends and holidays. Then scale the advertising. The case volume you get from $5,000 per month in ads with an immediate follow-up system will exceed what most firms get from $15,000 per month without one.
The only number that tells you whether your advertising is working is cost per signed case. Not cost per click, not cost per lead. Cost per signed case. Divide total advertising spend last month by cases signed from advertising last month. That is your number.
A good cost per signed case is 5 to 10 percent of your average attorney fee. If your average case generates $50,000 in fees, a cost per signed case under $5,000 is strong. If you are above that threshold, the question is not whether to spend more on advertising. The question is where in the system the conversion is breaking down.
Common breakdowns: the landing page is not converting (test your quiz funnel against your homepage on the same traffic), the follow-up is too slow (audit the timestamps from lead submission to first contact), or the intake is not qualifying leads correctly (review calls where the lead did not sign to find patterns). Fix the breakdown before increasing the budget.

Cost per click: $80 to $500+ depending on market. Starting budget: $1,500 to $3,000 per month. Ideal for: any PI firm with a converting funnel. Converts at 6 to 12 percent with a quiz funnel, 1 to 2 percent on a homepage. Requires dedicated call tracking per campaign to measure cost per signed case accurately.
Cost model: pay per lead, not per click. Budget: $500 to $3,000 per month depending on market and lead volume cap. Ideal for: any PI firm that qualifies for Google Screened status. Run alongside Google Search Ads. Converts at a higher rate than standard ads because the Google Screened badge pre-qualifies the lead’s trust level before contact.
Cost per click: $5 to $25. Cost per lead: $50 to $200 with the right creative. Starting budget: $1,000 to $2,000 per month. Ideal for: firms that have their follow-up system built because Facebook leads require more touchpoints. Best creative: quiz-style hooks, educational video, and specific accident-type targeting rather than generic lawyer ads.
The most expensive advertising mistake a PI firm makes is running ads before the intake system is built. Advertising delivers leads. An intake system converts them. Running one without the other is paying to generate activity that never turns into revenue.
The correct build sequence is: quiz funnel and landing pages first, then the AI intake agent that calls every lead within seven minutes, then the SMS follow-up sequence for leads who do not answer, then the ad campaigns. In that order. A firm that completes this sequence and then runs $3,000 per month in Google Ads will consistently outperform a firm running $10,000 per month into a homepage with no follow-up system. The difference is not the advertising budget. It is what the advertising budget is running into.
Crisp documented this sequencing principle in their work with high-growth law firms. The firms that scale quickly are not the ones spending the most on ads. They are the ones with the tightest conversion rates at the bottom of the funnel, which makes every dollar of advertising produce more cases at a lower cost per signed case.
When your advertising is working, you can answer the following questions without looking anything up. What is your current cost per signed case from Google Ads? From Facebook? What percentage of your advertising-generated leads do you contact within ten minutes? What percentage sign within the first call versus requiring follow-up? Which channel produced the most signed cases last month?
If you cannot answer these questions, your advertising is not working correctly. You may be signing cases. You may even be signing enough cases to justify the spend. But you are not running an advertising system. You are running a budget and hoping.
The shift from hoping to knowing starts with call tracking, then a dedicated intake process, then a reporting dashboard that shows cost per signed case by channel updated monthly. Once those are in place, advertising decisions stop being guesses and become simple arithmetic. The channel with the lowest cost per signed case gets more budget. The channel with the highest gets cut or improved. That discipline, applied consistently, is what separates PI firms that grow predictably from firms that have good months and bad months with no explanation for either.
Personal injury attorneys collectively spend $3.2 billion per year on advertising in the United States, with $2.5 billion on television alone. That grew 39 percent between 2020 and 2024. Individual firm spend ranges from $5,000 to $15,000 per month for small firms in mid-sized markets up to $40,000 to $150,000 per month for larger firms in top-15 metro markets. The right number for your firm is not an industry average. It is the budget that produces cases at or below your target cost per signed case.
Personal injury Google Ads cost between $80 and $500 or more per click depending on the market and keyword specificity. Broad terms like car accident lawyer near me in major metros exceed $300 per click regularly. More specific terms in mid-sized markets cost $80 to $150 per click. The cost per click is less important than the cost per signed case. A $300 click that converts into a $150,000 case at a 2 percent conversion rate costs $15,000 per signed case. A $100 click on the same traffic converting at 8 percent costs $1,250 per signed case. The funnel is more important than the click cost.
Yes. LSAs appear above standard Google Ads, carry the Google Screened badge, and charge per lead rather than per click. For most PI firms they produce a lower cost per lead than standard Google Ads because you pay only when someone contacts you through the listing. The limitation is budget caps and geographic coverage. Run LSAs alongside Google Search Ads rather than choosing one over the other. Together they cover more of the search results page and produce leads at different price points.
Traditional broadcast TV works for PI firms that can sustain enough frequency to build recognition, which typically requires $20,000 or more per month on television alone in a regional market. Below that threshold, the reach is too thin to achieve the repetition required. Connected TV advertising on streaming platforms works at lower budgets because it allows geographic and demographic targeting, and attribution is more trackable through landing page URLs. For most small to mid-size PI firms, digital channels produce more measurable results per dollar than traditional broadcast TV.
The best channel depends on your market, budget, and whether your intake system is built. Google Search Ads capture the highest-intent leads. Google LSAs produce leads at a lower cost per contact. Facebook generates demand rather than capturing it, which requires more follow-up but can produce volume at lower cost. The best advertising system uses two or three channels feeding one converting funnel, with call tracking on every channel and monthly reporting on cost per signed case by source. Picking one channel and ignoring the others leaves cases on the table.
