CTV Inventory and Measurement

Fastest-growing programmatic surface. Inventory landscape, formats, targeting, measurement, frequency, attribution.

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.
