Why Law Firms Are Shifting to CTV Advertising

44.8% of TV is streaming. 90% of households use CTV. 23% higher ROI than broadcast. CTV gets 38% of impressions but 63% of conversions. That's why.

The biggest PI law firm brands were built on television. Now those same firms, and ambitious competitors, are shifting budgets to CTV. Here’s why.

The Audience Migration

The most fundamental driver: viewers have moved.

You can’t advertise to people where they aren’t. As viewership shifts to streaming, advertising must follow. Cord-cutting isn’t just young people anymore. The 35-54 demographic, core PI client potential, is substantially streaming.

The Attribution Gap Closes

For decades, law firms ran TV ads on faith. You spent money, hoped phones rang, and tried to correlate timing with results. Proving TV ROI was essentially impossible.

CTV changes this:

  • Household-level tracking: 90%+ match rates connect ad exposure to website visits
  • Conversion attribution: Track forms, calls, and cases back to CTV exposure
  • Multi-touch visibility: See how CTV influences other channel performance

CTV accounted for 38% of impressions but 63% of attributable conversions, demonstrating measurable impact that traditional TV can’t provide.

Partners can now see television ROI. That visibility changes budget conversations.

The Targeting Advantage

Traditional TV wastes impressions by design. Everyone watching a program sees your ad, whether they’re potential clients or not.

CTV eliminates that waste:

  • Target specific zip codes (not just DMAs)
  • Layer behavioral signals (auto loans, motorcycle owners, workers’ comp researchers)
  • Reach intent audiences (legal research behavior, competitor website visitors)
  • Exclude existing clients and irrelevant households

The efficiency difference is 2-3x. Reaching 25% potential clients at $42 CPM beats reaching 8% at $25 CPM.

The Optimization Capability

Broadcast TV is static:

  • Buy flights weeks or months ahead
  • Limited ability to change mid-flight
  • Optimization happens between campaigns
  • Learn slowly, adjust slowly

CTV is dynamic:

  • Adjust budgets in real-time
  • Pause underperforming segments immediately
  • Test creative variations continuously
  • Learn fast, adjust fast

ROAS improves 6.6% after 30 days and 24% after 90 days with consistent CTV investment. That improvement comes from continuous optimization traditional TV doesn’t allow.

The Competitive Pressure

As sophisticated firms shift to CTV, they gain advantages:

  • Better targeting = more efficient spend
  • Attribution = provable ROI = bigger budgets
  • Optimization = compounding improvement

Firms still on broadcast-only face competitors who:

  • Reach audiences they can’t (cord-cutters)
  • Spend more efficiently
  • Improve faster

The competitive gap widens over time. Early CTV adopters build advantages that compound.

The Cost Structure Shift

CTV pricing has evolved favorably:

Inventory growth: Every major streaming service now has ads. Supply increased dramatically.

CPM compression: By 2025, only Netflix and Max average CPMs above $30. Most platforms have settled into competitive ranges.

Direct buying efficiency: Direct auctions average $14 median CPM floor vs. $19.50 for resold inventory.

CTV has become more affordable as it’s become more capable.

The Integration Opportunity

CTV creates a system opportunity traditional TV couldn’t:

CTV + Search coordination:

  • CTV generates branded searches
  • 75% of consumers search after seeing TV ads
  • Search campaigns capture CTV-generated demand
  • Attribution connects the system

CTV + Retargeting:

  • Identify households exposed to CTV
  • Retarget across digital channels
  • Reinforce message across devices

CTV + Social:

  • Coordinate messaging across screens
  • Sequence awareness → consideration → action

Traditional TV operates in isolation. CTV integrates with digital marketing.

The Local Opportunity

Local CTV advertising is the fastest-growing segment:

PI firms serve local markets. CTV targeting aligns perfectly: zip codes, radius targeting, DMA precision.

The Strategic Shift

Firms aren’t just moving budget. They’re changing strategy:

Old Broadcast Model

  • Mass reach, hope for response
  • Measure by phone ring correlation
  • Optimize between quarterly flights
  • Television as standalone channel

New CTV Model

  • Targeted reach, measured response
  • Track from impression to case
  • Optimize continuously in real-time
  • Television integrated with digital

This is fundamental transformation, not just budget reallocation.

The Holdout Risk

Firms delaying CTV adoption face growing risk:

Audience erosion: Broadcast-only reach shrinks each year as streaming grows.

Competitive disadvantage: CTV adopters improve efficiency while you don’t.

Talent gap: Marketing teams with CTV experience increasingly valuable.

Attribution blindness: Can’t prove TV ROI = can’t defend TV budget.

The question isn’t whether to shift. It’s how fast and how completely. Every quarter you wait, competitors build advantages you’ll have to overcome.
