Are TV Leads Worth It for Personal Injury Firms? How to Measure What You're Actually Getting

Your TV rep says the campaign is working. Your intake team says TV callers are different — more committed, better cases. But when your managing partner asks what you're paying per signed case for TV versus Google LSA, you go quiet. That silence is the problem. Most PI firms spending $50,000–$150,000 a month on broadcast cannot produce a reliable cost per case for the channel — not because the data doesn't exist, but because the infrastructure to connect it hasn't been built.

This guide breaks down how to measure TV lead ROI for a personal injury firm: what data you need, why broadcast is structurally harder to track than digital, and what a reliable cost per case calculation looks like when the math actually holds up.

Why TV ROI Is So Hard to Measure Accurately

Digital channels have built-in attribution infrastructure. A Google Ads click carries UTM parameters. An LSA lead has a timestamp and source number from Google's system. A Facebook ad fires a pixel event. TV has none of that. A viewer sees your commercial, picks up their phone — and calls hours or days later, or Googles your name instead. That gap is your attribution problem.

The result: TV spend either gets full credit for every brand search that followed a commercial airing, or it gets zero credit because no one can prove the connection. Both errors distort your cost per case significantly.

The Tools TV Advertisers Actually Use for Attribution

There are practical approaches to TV attribution that move you from guessing to data-informed. None are perfect. Used together, they tell a reasonable story.

Dedicated Phone Numbers by Market and Daypart

Assign dedicated tracking numbers to your TV campaigns — by market if you run multiple markets, and by daypart (morning, afternoon, prime time, late night). Calls on those numbers attribute directly to TV with high confidence. CallRail integrates with most PI intake systems and makes this a one-day setup.

The limitation: viewers who see your commercial but call your main line, visit your website, or search your name on Google won't appear on the TV-specific number. Expect dedicated tracking to undercount TV-influenced leads by 20–40%.

Geo-Lift and Time-Lift Analysis

Run TV in one market and not another for 60–90 days. Compare call volume and case intake between markets. The difference — controlling for other variables — gives you a rough lift estimate attributable to TV. Imperfect, but directionally useful. Especially valuable when entering a new market or deciding whether to pull back on spend.

Intake Source Questioning

Train your intake team to ask every caller: “How did you hear about us?” Record the answer in your intake system. Many TV-influenced callers will say “I saw your commercial” even when they called your main line. The data is imprecise, but it adds real signal. Firms that consistently capture it cut their TV attribution uncertainty significantly over time.

Building Your TV Cost Per Case Calculation

With attribution data in hand — however imperfect — here is how to build a working TV cost per case:

• Total TV spend (rolling 90 days): Include media buy, production amortized over the run, and any agency fees. Most firms undercount TV cost by excluding production — those costs belong in the attribution window.
• TV-attributed leads: Pull calls from dedicated TV tracking numbers, plus intake source responses indicating TV, plus a reasonable estimate for untracked TV influence based on your lift analysis.
• Signed cases from TV-attributed leads: Of those leads, how many became signed clients? Pull from your case management or intake system, filtered by TV source codes.
• TV cost per case: Total TV spend ÷ signed cases.

A firm spending $60,000 a month on TV — including production — that generates 40 attributed signed cases is running at $1,500 per case. Excellent, if your portfolio skews moderate-to-high severity. The same spend producing 12 signed cases lands at $5,000 per case. That number demands either a strategy change or a sharper attribution methodology before you draw any conclusions.

The 6–18 Month Settlement Lag Complicates TV ROI Even Further

Cost per signed case is a leading indicator of TV ROI. The true measure is cost per settled case — which requires waiting out PI settlement timelines. For heavy TV spenders, the 6–18 month lag between signing a case and receiving a settlement means TV's actual ROI won't be clear for 12–24 months after a campaign runs.

That's not a reason to avoid measurement — it's a reason to start now, so you have a reliable historical dataset when the settlement data arrives. Firms that wait until they want to evaluate TV before connecting the data end up with years of spend they cannot explain.

Comparing TV Cost Per Case to Your Digital Channels

TV ROI only means something in comparison. Here is the framework for an honest cross-channel view:

• Cost per signed case: TV vs. LSA vs. aggregators vs. SEO. Is TV producing cases at a competitive cost, or is it your most expensive channel?
• Case severity distribution: TV advertising reaches a broader demographic and often captures higher-severity cases — catastrophic injuries, wrongful death — that higher-intent digital searches may not generate. If TV cases settle at higher average values, a higher cost per case may still represent better ROI.
• Brand lift effect:TV creates awareness that benefits your entire acquisition strategy. Your Google Ads quality score improves. LSA call volume increases. Branded search traffic grows. Some of those downstream effects belong in TV's ROI calculation, even when they're difficult to quantify precisely.

Signs Your TV Spend Is Not Worth It (With Numbers)

TV may not be delivering for your firm if:

• TV cost per case is more than 2x your best-performing digital channel, with no meaningful difference in case severity.
• You can't attribute more than 30% of your TV spend to specific cases — your attribution infrastructure is too weak to make data-driven decisions at all.
• TV-attributed leads have rejection rates above 35%, suggesting the creative is generating curiosity calls rather than qualified prospects.
• You've been running the same creative for 12+ months with no performance data to justify the approach.

Signs TV Is Worth Scaling (With Numbers)

TV is likely worth maintaining or increasing if:

• TV cost per case is within 20–30% of your digital average, and TV cases carry higher average expected settlement values.
• Your branded Google search volume has increased measurably since launching TV — confirming the brand awareness effect is real and quantifiable.
• Your intake team reports that TV callers arrive further along in their decision — they've already decided to hire an attorney and are calling to choose one, not to explore options.

What This Requires From Your Data Infrastructure

Measuring TV ROI accurately requires three things: intake source tracking, dedicated tracking numbers, and a system that connects lead source codes to case outcomes over time. Most PI firms running TV spend cannot produce a reliable cost per case for the channel — because that infrastructure doesn't exist yet.

Building it doesn't require a technology overhaul. It requires consistent source coding at intake, a tracking number setup that takes a day to configure, and a reporting workflow that compares TV-attributed cases to TV spend on a rolling 90-day basis.
