Billboards and CTV both build awareness. But they work very differently. Understanding the trade-offs helps you allocate budget effectively.
The Fundamental Difference
🛣️ Billboards
- Static message, fixed location
- Everyone passing sees it (maybe)
- Location-based
- No targeting control
📺 CTV
- Dynamic video to targeted households
- Only your defined audience sees it
- Audience-based
- Full targeting control
Reach Comparison
Billboards
- Reach: Everyone driving past
- Targeting: Geographic only (this road, this intersection)
- Frequency: Depends on driving patterns
- Control: None. You get everyone or no one
A well-placed billboard might get 50,000+ daily impressions. But how many are potential PI clients? How many are even from your service area?
CTV
- Reach: 90% of U.S. households via streaming
- Targeting: Geographic + demographic + behavioral
- Frequency: Controlled per household
- Control: Full. Reach exactly who you define
CTV reaches 1,000 targeted households more efficiently than billboards reach 100,000 random passersby.
Targeting Comparison
Billboard Targeting
What you can target:
- Physical location (this highway, this intersection)
- General demographics of traffic (commuter routes vs. downtown)
What you can’t target:
- Specific behaviors
- Income levels
- Age ranges
- People who actually need lawyers
CTV Targeting
What you can target:
- Specific zip codes
- Behavioral signals (auto loans, motorcycle owners)
- Demographic filters
- Intent signals (legal research behavior)
- Your first-party data (client lookalikes)
See Why Demographic Targeting Wastes Budget.
Message Comparison
Billboard Constraints
- 6-8 words maximum
- Static image only
- No audio
- No storytelling arc
CTV Capabilities
- 15-30 seconds of video
- Full audio-visual experience
- Complete storytelling arc
- 94-96% completion rates
You can communicate a brand impression with a billboard. CTV delivers your full message with emotional impact.
Measurement Comparison
Billboard Measurement
What you can measure:
- Estimated impressions (traffic counts)
- Location visibility studies
What you can’t measure:
- Who actually saw your billboard
- Whether it drove action
- Website visits from billboard exposure
- Calls attributed to billboard
- ROI with any confidence
Billboards are essentially unmeasurable at the response level.
CTV Measurement
What you can measure:
- Exact impressions delivered
- Household-level exposure
- Verified website visits
- Attributed conversions
- Cost per lead and cost per case
CTV accounted for 38% of impressions but 63% of attributable conversions. Measurement that proves ROI.
Cost Comparison
Billboard Costs
| Market | Monthly Cost |
|---|---|
| Small market | $1,500-3,500 |
| Mid market | $3,000-8,000 |
| Major market | $5,000-15,000+ |
| Premium locations | $10,000-30,000+ |
Plus production: $500-2,000 for design/printing.
Cost per impression: Extremely low (fractions of a cent) Cost per qualified impression: Unknown (unmeasurable)
CTV Costs
| Market | Monthly Budget |
|---|---|
| Small market | $15,000-25,000 |
| Mid market | $30,000-50,000 |
| Major market | $50,000-80,000 |
| Top market | $75,000-150,000+ |
Plus production: $15,000-40,000 for initial creative.
Cost per impression: $0.035-0.050 (CPM) Cost per qualified impression: Measurable (targeted audience)
CTV’s higher absolute cost comes with targeting and measurement that billboards lack.
Strategic Uses
When Billboards Make Sense
- Specific location relevance: Near hospitals, crash sites, major intersections
- Pure brand building: When measurement isn’t required
- Budget constraints: Can’t afford minimum viable CTV
- Supplement: Adding to existing TV/CTV presence
- Iconic placement: “Own” a famous location
When CTV Makes Sense
- Growth objectives: Need to build market presence with measurement
- Targeting needed: Want to reach specific household types
- Accountability required: Must prove ROI to partners
- Competitive markets: Need differentiation beyond location
- Full-funnel approach: Integrating awareness with search capture
The Attention Factor
Billboard Attention
- Viewed while driving (distracted)
- Competes with traffic, phone, passengers
- No engagement mechanism
- Hope they looked up
CTV Attention
- Viewed in living room (relaxed)
- Sound and motion capture attention
- Full-screen, lean-back experience
- Nearly everyone watches the full ad
The depth of attention is incomparable.
Integration Considerations
Billboard + CTV
Billboards can reinforce CTV messaging:
- Same visual identity
- Same tagline
- Location presence + household reach
- Brand consistency across touchpoints
Billboard Without CTV
Billboards alone provide:
- Location-based awareness
- Brand presence in physical space
- Unquantifiable impact
- Limited targeting
CTV Without Billboard
CTV alone provides:
- Targeted household reach
- Measurable attribution
- Full messaging delivery
- Optimization capability
Most firms prioritize CTV over billboards given measurement advantages.
The Verdict
For most PI firms with growth objectives and accountability requirements, CTV outperforms billboards:
| Factor | CTV | Billboard |
|---|---|---|
| Targeting | ✓✓✓ | ✗ |
| Measurement | ✓✓✓ | ✗ |
| Message depth | ✓✓✓ | ✗ |
| Attention quality | ✓✓✓ | ✗ |
| Location specificity | ✗ | ✓✓✓ |
| Budget flexibility | ✓ | ✓✓ |
| ROI provability | ✓✓✓ | ✗ |
Billboards are a supplemental tactic for specific location objectives. CTV is a strategic growth driver, and the same logic applies even more clearly against cable TV’s shrinking audience.
