CTV Advertising for Law Firms: The Complete Guide

79% of households stream. 83% of legal ad spend is still broadcast. CTV closes that gap. Here's how targeting, costs, and measurement actually work.

Connected TV advertising puts your firm on the big screen (Hulu, Peacock, YouTube TV, local news apps) with targeting and measurement that traditional broadcast can’t touch.

This guide covers everything: how CTV works, what it costs, how to measure results, and why it’s becoming the primary awareness channel for growth-focused law firms.

For the full picture of where legal ad dollars are moving, see our 2026 market analysis covering $72M in monthly spend across 28 DMAs.

What Is CTV Advertising?

CTV (Connected TV) is television content streamed via internet-connected devices: smart TVs, Roku, Amazon Fire TV, Apple TV, and gaming consoles. When someone streams content on these devices, they see ads. Your ads, if you’re running CTV campaigns.

CTV is not cable TV (linear, scheduled programming), broadcast TV (over-the-air signals), or YouTube on a phone (that’s mobile video). CTV is streaming content on a television screen with programmatic ad delivery that’s targeted, measurable, and runs across premium inventory from major networks and apps.

A related term is OTT (Over-The-Top), which is video content delivered over the internet, bypassing traditional cable and broadcast distribution. CTV is a subset of OTT: it specifically refers to OTT content watched on a television screen rather than mobile devices or computers.

The distinction matters because CTV combines the impact of television (big screen, living room, high attention) with the precision of digital advertising.

Why CTV Matters for Law Firms

The Audience Has Moved

WHERE TV VIEWING HAS SHIFTED

According to Nielsen, streaming now accounts for 44.8% of total TV viewing, surpassing broadcast and cable combined for the first time. For adults under 50, it’s the majority. If your advertising strategy is broadcast-only, you’re missing a growing share of your market.

The people you’re trying to reach (adults who drive, work, own homes, have families) are watching Netflix, Hulu, YouTube TV, and local news apps on their smart TVs. CTV reaches them there.

Targeting Changes Everything

Broadcast TV is a blunt instrument. You buy a time slot on a local station and hope your target audience is watching.

CTV enables household targeting, delivering ads to specific households based on demographics, behaviors, and data signals rather than broad program-based buying. You can target by demographics (age, income, household composition), geography (down to zip code or radius around your office), behaviors (auto loan holders, homeowners, people researching legal topics), and intent signals (recent searches, website visits, in-market indicators).

Instead of reaching everyone watching the 6 PM news, you reach households that match your ideal client profile, regardless of what they’re watching.

Measurement Is Real

Broadcast TV measurement is statistical estimation. Ratings tell you approximately how many people might have seen your ad.

CTV measurement is deterministic. You know exactly how many households saw your ad, which households visited your website after exposure, which converted (called, filled out a form), and your cost per lead and cost per case. This isn’t correlation. It’s attribution: tracking the connection between ad exposure and business outcomes like website visits, calls, and signed cases.

How CTV Advertising Works

The Technical Flow

You define your audience (geography, demographics, behaviors), then the platform identifies matching households using data from streaming apps, devices, and third-party sources. Your ad serves when they stream on any content they watch. The platform tracks exposure, recording which households saw your ad, and attribution connects outcomes by matching website visits and conversions back to exposed households.

Inventory: Where Your Ads Run

CTV ads run across premium streaming content including major streaming apps (Hulu, Peacock, Paramount+, Discovery+, Max with ads), live TV streaming (YouTube TV, Sling, FuboTV), free ad-supported streaming like Pluto TV, Tubi, Freevee, and local news apps, plus network apps from ABC, NBC, CBS, and Fox.

Your ads appear in commercial breaks, just like traditional TV, but only to the households you’re targeting.

Ad Formats

The standard :30 spot gives you enough time to tell a story, establish credibility, and deliver a message. :15 spots work well for frequency and reinforcement, particularly for retargeting or brand reminders. :60 spots are less common, used for complex messages or storytelling, though some inventory doesn’t accept them.

According to IAB research, CTV ads are non-skippable with completion rates averaging 94-96%. When your ad serves, it gets watched.

CTV Targeting for Law Firms

Geographic Targeting

  • DMA (Designated Market Area): Nielsen-defined geographic regions used for local television advertising, covering entire TV markets like Dallas-Fort Worth.
  • State: Follows state boundaries.
  • Zip code: Include specific areas or exclude ones you don’t serve.
  • Radius: Reach households within a set distance from your office.

For most law firms, DMA targeting with zip code exclusions is the right balance: broad enough for reach, refined enough to avoid waste.

Demographic and Behavioral Targeting

Demographic targeting covers age ranges, household income levels, home ownership status, and presence of children. But behavioral targeting is where CTV gets powerful for law firms:

  • Auto-related segments: Reach current auto loan holders, recent auto purchasers, and multiple vehicle households. Ideal for auto accident practices.
  • Employment segments: Target specific industries and job types for workers’ comp or employment law cases.
  • Health-related segments: Reach people researching specific conditions or medications for mass tort campaigns.
  • Legal intent segments: Find people actively researching lawyers and legal topics.

Behavioral targeting comes from aggregated data (purchase history, browsing behavior, survey responses) matched to households.

First-Party Targeting

You can upload your own data for targeting:

  • CRM lists: Target households matching your past client profiles.
  • Website visitor retargeting: Reach people who’ve already been to your site.
  • Exclusion lists: Keep current clients from seeing ads.

First-party data is powerful but requires sufficient list size, typically 5,000+ records for matching.

CTV Measurement and Attribution

What You Can Measure

CTV platforms track impressions (times your ad served), reach (unique households exposed), frequency (average exposures per household), and completion rate (typically 95%+). More importantly, they measure verified visits (households that saw your ad AND visited your website), conversions (form submissions, phone calls, chat initiations), and efficiency metrics like cost per visit and cost per lead.

How Attribution Works

CTV attribution uses household-level matching. The platform records IP address and device ID when your ad serves. When someone visits your website, their IP/device is captured. The platform matches website visitors to ad exposure, and if a match occurs within the attribution window (typically 14-30 days), it’s counted as a verified visit.

For phone calls, integration with call tracking platforms like CallRail or Invoca enables call attribution back to CTV exposure.

Attribution Windows and Benchmarks

A 7-day window is conservative with high confidence. 14 days is balanced and typical for local services. 21-30 days suits longer consideration cycles. For personal injury, 14-21 days is appropriate. Someone sees your ad, gets in an accident a week later, searches for you, and that’s a valid attribution path.

Realistic benchmarks for law firm CTV campaigns:

MetricTypical Range
CPM$30-50
Completion rate95%+
Verified visit rate0.4-1.0%
Cost per verified visit$30-75
Cost per lead$200-500

Results vary by market, targeting, creative quality, and practice area. For deeper analysis, see our guide to CTV ROI benchmarks.

CTV Costs and Budgeting

How Pricing Works

CTV is priced on CPM (Cost Per Thousand), the cost to deliver 1,000 advertising impressions. You pay for ad deliveries, not clicks or outcomes.

Inventory TypeCPM Range
Premium (Hulu, Peacock)$40-55
Mid-tier streaming$30-45
FAST channels (Tubi, Pluto)$20-35
Blended/programmatic$32-45

CPMs vary by inventory quality, targeting specificity (tighter targeting = higher CPM), seasonality (Q4 and election years are higher), and market (major metros cost more). For a detailed breakdown, see CTV CPM rates explained.

Monthly Budget Recommendations

Market SizeMinimumRecommended
Small DMA (under 300K households)$12-15K$18-25K
Mid DMA (300K-800K)$20-30K$35-50K
Large DMA (800K-2M)$35-50K$60-90K
Top 10 DMA$60-80K$100-150K

These budgets achieve meaningful reach and frequency. Below minimum, you’re not reaching enough households often enough to build awareness. For market-specific guidance, see CTV budget by market size.

What Budget Gets You

At $30K/month in a mid-size market, expect roughly 750,000-1M impressions, 150,000-200,000 households reached, 5-6 frequency per household, 4,500-7,500 verified visits, and 60-150 leads depending on conversion rate.

Beyond Media: Full Campaign Costs

CTV campaigns involve more than media spend:

  • Creative production: $10-50K for quality :30 spots.
  • Platform fees: Often included in CPM or add 10-15% of spend.
  • Management fees: Apply if working with an agency.
  • Tracking setup: Call tracking and pixel implementation.

Plan for creative as a real investment. Cheap creative undermines expensive media. See hidden costs of CTV advertising for the full picture.

CTV Creative for Law Firms

What Works

  • + The hook (first 3 seconds): Interrupt with relevance. Their problem, not your firm
  • + Credibility (seconds 4-15): Specific experience, results, specialization
  • + Emotional connection (seconds 10-20): Real stories and real stakes
  • + The call to action (final 5-8 seconds): Large phone number, firm name, clear next step

What Doesn't Work

  • Starting with your logo (nobody cares until you've established relevance)
  • Generic stock footage (looks like every other law firm ad)
  • Cramming too much information (one message, one CTA)
  • Weak audio (CTV is sound-on, so invest in professional voiceover)
  • Tiny phone numbers (if they can't read it from the couch, it's useless)

Creative Rotation

Don’t run one ad forever. Plan for:

  • 2-3 variations minimum to prevent fatigue
  • Refresh every 8-12 weeks in heavy-frequency campaigns
  • Test different hooks to find what resonates
  • Seasonal relevance when appropriate (winter driving, summer activities)

For production guidance, see CTV creative production requirements.

Social is good for retargeting and reinforcement. CTV is better for initial awareness and brand building. The big screen carries more weight than the phone screen. See CTV vs social media ads.

Getting Started with CTV

Platform Options

  • Managed service platforms (MNTN, Tatari): Handle campaign management with built-in optimization. The right choice for most law firms focused on performance.
  • Self-service platforms (The Trade Desk, Roku OneView): Give you direct control but require expertise and ongoing management time.
  • Direct publisher deals (Hulu, Peacock): Guarantee premium inventory but come with higher minimums and less targeting flexibility.

For most law firms, managed service platforms offer the right balance of capability and simplicity. See self-serve CTV vs managed for help deciding.

Implementation Essentials

CTV is not a switch you flip for immediate leads. It builds awareness that converts over time. Give it at least 90 days before evaluating success.

Branded Search Protection

This is critical and often missed.

THE SECOND-SCREEN REALITY

$1-10 branded keyword CPC vs $50-150+ generic Source: Industry Data

When your CTV ad works, people don’t call immediately. They grab their phone and search your name. If competitors are bidding on your brand terms, they intercept your leads. According to MNTN Research, 65% of second-screen users go to an advertiser’s website while streaming, but they often search first.

CTV creates demand. Search captures it.

If you’re running CTV without protecting your branded search terms, you’re paying to generate leads for competitors.

Branded search protection means bidding on your own firm name, defending against competitor conquesting, coordinating CTV and search timing, and capturing the demand you create. This is why CTV can’t be run in isolation. It’s part of a system. See our complete guide to branded search protection.

The Taqtics Approach

We run CTV differently.

Exclusivity: When we work with a firm, competitors in your market can’t access our custom audiences. Your targeting is yours alone.

Full-service creative: We produce the spots: strategy, scripting, production, editing. No hand-off to a third-party production house.

Search integration: CTV and branded search run as one coordinated system. We create demand and capture it.

Real attribution: Connected tracking from impression to lead to signed case. You know what’s working.

Transparent reporting: You see everything: impressions, reach, frequency, visits, conversions, costs.
