- Advertiser and creative identifiers
- ATC first and last display dates
- Public YouTube video ID and view count
Data methodology
What Cero observes, calculates and leaves unknown.
Cero organizes public advertising records and YouTube metrics. Every public output must distinguish source observations, deterministic calculations, interpretive signals and AI-assisted judgments.
계산
Calculated
Deterministic transformations of observed fields. The formula and denominator must be reproducible.
- Deduplication by canonical YouTube video ID
- Display-period duration from ATC dates
- Counts and aggregates over a complete snapshot
추정
Inferred
Signals that can support research but cannot establish spend, performance or current campaign status.
- A 21-day display period is a long-running signal only
- Absence is unknown when collection is partial
- Public views include paid and organic uncertainty
AI 판단
AI-assisted
Creative observations generated from a versioned prompt and rubric. They require verification against the original video.
- Hook, retention and CTA rubric judgments
- Scene descriptions and timestamps
- Suggestions, not audited business outcomes
Cero does not know these values from public sources
- Exact advertising spend or cost per view
- Conversions, revenue, ROAS or profit
- Whether a campaign is live at this moment
- Targeting, bidding or attribution settings
- Why an advertiser kept or stopped a creative
- A causal relationship between duration and performance
