When you pay for a video ad, does anyone actually watch it? On CTV, the answer is almost always yes.
What is Video Completion Rate?
Video completion rate (VCR) measures the percentage of video ads that viewers watch to the end. A 90% completion rate means 90 out of 100 impressions were watched completely.
This metric matters because an unwatched ad has no value. You’re paying for attention. Completion rate tells you if you’re getting it.
CTV Completion Rate Benchmarks
CTV delivers exceptionally high completion rates:
These numbers are consistent across multiple industry sources. When you run CTV ads, viewers watch them.
By Ad Length
15-second ads: ~94.5% completion 30-second ads: ~92-96% completion
Shorter ads complete at slightly higher rates, but even 30-second spots see over 90% completion. This is remarkable compared to other digital video.
CTV vs YouTube Completion
The contrast with YouTube is stark:
YouTube: 20-40% completion rates (often lower) CTV: 90%+ completion rates
Why the difference?
YouTube’s skip button: Viewers can skip most YouTube ads after 5 seconds. Many do. You pay for an “impression” where someone watched 5 seconds and left.
Lean-forward vs. lean-back: YouTube viewers are actively engaged with their mouse, ready to skip. CTV viewers are in TV mode, sitting back, watching content, not poised to click away.
Screen environment: CTV is full-screen TV viewing. YouTube on desktop is often one of many tabs. Attention is higher on CTV.
CTV vs Social Video Completion
Social video (Facebook, Instagram, TikTok) faces similar challenges:
Social video: Often 10-30% completion, sometimes lower CTV: 90%+ completion
Social feeds encourage scrolling. Videos auto-play but viewers scroll past quickly. Sound is often off. The environment works against full viewing.
CTV is the opposite. Non-skippable. Sound on. Full attention.
Why CTV Completion Rates Are So High
Several factors combine to deliver 90%+ completion:
Non-Skippable Format
Most CTV inventory is non-skippable. There’s no button to press. The ad plays, and viewers watch it, just like traditional TV commercials.
Full-Screen Environment
CTV ads fill the television screen. There’s no other content competing for attention. No sidebar, no other tabs, no scrolling feed.
Lean-Back Viewing
CTV viewers are in “TV mode,” relaxed, watching content, not actively engaging with a device. They accept commercial breaks as part of the TV experience.
Quality Content Context
CTV ads appear within streaming content people chose to watch. They’re invested in the show. They’ll wait through ads to continue.
No Easy Exit
On desktop or mobile, closing a tab or scrolling away is instant. On CTV, changing apps or leaving takes more effort. Viewers ride out the ad.
Viewability Benchmarks
Beyond completion, viewability confirms ads were actually displayed on screen:
CTV viewability: 95%+ is typical for non-skippable inventory Desktop video viewability: Often 60-70% Mobile video viewability: Varies widely, often lower
CTV’s full-screen format essentially guarantees viewability. The ad fills the TV. It’s visible by definition.
What This Means for Law Firms
High completion rates have practical implications:
Your Message Lands
When you pay for a CTV impression, someone watched your entire commercial. Your brand name, phone number, and message were seen. This isn’t guaranteed on other platforms.
Creative Investment Pays Off
Because completion rates are high, investing in quality creative makes sense. Viewers will see your entire spot. Make it count.
CPM Context Changes
CTV CPMs ($20-$40) look higher than YouTube CPMs. But when 90%+ watch the full ad versus 30% on YouTube, the effective cost per completed view may favor CTV.
Frequency Builds
High completion means each impression counts. You can build awareness with fewer total impressions because each one is actually viewed.
The Bottom Line
CTV’s 90%+ completion rates are one of its biggest advantages. When you pay for an impression, someone watches your ad. That’s the fundamental promise of TV advertising, and CTV delivers on it in ways that other digital video can’t match.
For law firms, this means your CTV investment goes further. Every impression is a real exposure to your message. That’s worth paying a premium for.
