CTV Advertising for Law Firms

Completion rate measures what percentage of viewers watch your entire ad. For CTV, this number is remarkably high. It fundamentally changes what streaming TV advertising is worth.

What Completion Rate Means

Video Completion Rate (VCR) = Viewers who watched 100% of ad / Total impressions × 100

A 95% completion rate means 95 out of 100 viewers watched your entire 30-second spot. Not the first 5 seconds. Not 50%. The whole thing.

CTV Completion Rate Benchmarks

COMPLETION RATES BY PLATFORM

94-96%

CTV/Streaming completion

— IAB/Innovid

15-30%

YouTube skippable completion

20-40%

Social video completion

70-85%

Linear TV completion (estimated)

The gap is dramatic. CTV viewers watch your message. Other channels, they skip, scroll, or ignore.

Why CTV Completion Rates Are High

CTV Advantages

Non-skippable format in most inventory

Lean-back living room environment

Lower ad load than traditional TV

Sound-on by default

Full-screen presentation with no distractions

Premium streaming runs fewer ads per hour than traditional TV. Viewers aren't fatigued by endless commercial breaks. They accept ads as part of the experience.

Why Completion Rates Matter for Law Firms

Message Delivery

1

0-5 seconds

Hook and attention grabber

2

5-15 seconds

Problem identification and empathy

3

15-25 seconds

Solution and credibility building

4

25-30 seconds

Call to action and firm name

If viewers skip at 5 seconds, they miss 80% of your message—including your firm name and phone number. With 95% completion, nearly everyone sees the full arc. That's the difference between "I saw a lawyer ad" and "I saw Smith & Jones."

Cost Efficiency

You pay for impressions. If 50% of viewers skip, you're paying for impressions that delivered partial value.

COST PER COMPLETED VIEW

CTV at $40 CPM, 95% completion

YouTube at $15 CPM, 25% completion

The "cheaper" channel is actually more expensive for delivered messages.

Attention Quality

Completion is one thing. Attention is another. CTV delivers both:

Mobile/social video attention

Viewers aren't just completing—they're paying attention.

Completion Rate by Spot Length

Spot LengthTypical Completion
15 seconds96-98%
30 seconds94-96%
60 seconds90-93%

Shorter spots complete slightly higher, but 30-second spots still achieve excellent rates. For PI messaging that needs to build empathy and credibility, 30 seconds with 95% completion beats 15 seconds with 97% completion.

Completion Rate vs. Other Metrics

Completion rate matters, but it's not the only metric:

MetricWhat It Measures
Completion RateDid they watch?
Verified Visit RateDid they visit your website?
Conversion RateDid they become a lead?
Cost Per LeadWhat did you actually pay?

High completion is necessary but not sufficient. Great creative with 95% completion and 0.3% verified visits beats mediocre creative with 95% completion and 0.1% verified visits. Completion gets the message seen. Creative makes it matter.

What Affects Completion Rates

Improves Completion

Engaging creative that maintains attention

Fresh creative (not over-exposed)

Premium content environments

Relevant audience targeting

Reduces Engagement

Repetitive creative causing tune-out

High frequency fatigue

Background/ambient viewing

Irrelevant audience (they complete but don't engage)

The Competitive Advantage

When competitors run YouTube pre-roll, 75% of their message is skipped. When you run CTV, 95% of your message is seen.
