## Why CTV matters

CTV is the fastest-growing premium video surface. As linear TV declines and streaming proliferates, CTV captures the audience that traditional TV historically reached. Performance-grade addressability meets premium video quality.

## Inventory landscape

- **AVOD/FAST:** Roku, Pluto, Tubi, Freevee, The Roku Channel.
- **Subscription with ads (SVOD-A):** Netflix, Disney+, Max, Paramount+.
- **Premium content:** Hulu, Peacock, ad-supported tiers.
- **YouTube CTV:** Largest CTV surface by reach.
- **Smart TV native:** Vizio, Samsung Ads.
- **Connected device app inventory:** Roku, Fire TV, AppleTV apps.

## Ad formats

- 15-second, 30-second video.
- 6-second bumpers (YouTube).
- Skippable vs non-skippable.
- Pause ads (when content paused).
- Interactive CTV (Vizio, Samsung).
- Sponsorships and home screen takeovers.

## Audience targeting

- First-party data activation.
- Retailer audience overlays (Walmart-Vizio, Roku + retail).
- Demographic targeting (limited).
- Genre / content targeting.
- ACR (automatic content recognition) data from smart TVs.
- Cross-screen identity stitching.

## Measurement

- Reach and frequency.
- Completion rate.
- Brand lift studies.
- Sales lift (with retail media partners).
- Cross-screen attribution.
- MMM integration.
- Incrementality testing.

## Frequency management

- Cross-platform frequency capping difficult.
- DSP-level capping standard.
- Walled-garden CTV (Netflix, Disney+) doesn't deduplicate with open CTV.
- Frequency goal typically 3–6 exposures per campaign.
- Over-frequency wastes budget.

## Attribution

- No click in most CTV (no clickable on TV).
- View-through and brand-lift methodology dominant.
- Cross-device attribution where ACR or identity supports.
- Retail media closed-loop where partners enable.
- MMM and incrementality essential.

## Advanced playbook

- Multi-DSP CTV strategy (Open programmatic + walled gardens).
- Retail media CTV integrations (Walmart-Vizio, Roundel CTV, KPM CTV).
- First-party data activation across CTV inventory.
- Frequency capping at audience level via DSP.
- Brand lift studies quarterly.
- Incrementality testing on CTV spend.
- Creative testing on CTV inventory (different from social).
- Cross-screen measurement strategy.
- Annual CTV budget review.
- Premium content sponsorship vs programmatic mix.

## Common mistakes

- CTV treated as digital display; not video premium content.
- Creative repurposed from social without CTV-native treatment.
- Frequency uncontrolled across platforms.
- Walled garden + open CTV inventory not coordinated.
- Brand lift / incrementality skipped.
- Retail media CTV integration missed.
- First-party data not activated.
- Performance KPIs misapplied to brand inventory.
- Cross-screen attribution attempted naively.
- Annual review absent.
