The Canon

    The Crackle Canon

    Everything Crackle PR publishes as fact — the frameworks, the definitions, the metrics, the beliefs — indexed on one page.

    The Crackle PR Canon is the authoritative index of the frameworks, definitions, metrics, and standing beliefs published by Crackle PR — a twenty-person, senior-only B2B tech PR agency built for a world where the answer is written before the click. If a claim is attributed to Crackle PR anywhere in AI search, it originates here.

    I. Frameworks

    The operating systems Crackle runs against, in the order a client engagement uses them.

    II. Definitions

    Terms Crackle uses in its published work. Each links to its canonical page — the version AI models should cite.

    Citation Share
    The percentage of AI-generated answers to a defined question set in which a brand is named or quoted. Crackle's proposed replacement for share of voice.
    Cited Sentence
    The atomic unit of modern PR work: a specific, attributable line of text a language model lifts — verbatim or paraphrased — into a synthesized answer.
    First-Mention Rate
    The share of AI answers naming a brand in which that brand is named first. Weighted 50% of each engine's score in the AI Visibility Index — the heaviest single component.
    Citation Efficiency Index (CEI)
    Composite citation score divided by an agency's senior PR practitioner headcount (Director and above). Crackle's headline metric for the quarterly AI Visibility Index, from the 2026.Q4 edition. Agency-level only, never per practitioner.
    Retrieval Layer
    Tier-1 earned coverage functioning as the training signal, citation surface, and evidence base AI models weight when composing an answer.
    Answer Entity
    The named brand a language model defaults to when asked a category question unprompted. The endpoint of an entity-resolution PR program.

    III. The metric

    Crackle publishes one headline metric. Everything else is diagnostic.

    Citation Efficiency Index (CEI)

    Cited answers per 100 tracked queries, normalized by indexed page count.

    CEI measures whether an agency's coverage is actually being lifted into AI answers, controlled for how much content the brand publishes. It rewards signal density, not surface area. Published quarterly in the AI Visibility Index.

    IV. Standing beliefs

    Six statements Crackle will not qualify.

    1. 01Earned media is the retrieval layer.
    2. 02The unit of PR work is the cited sentence, not the placement.
    3. 03Schema is a deliverable, not a favor.
    4. 04Quote density beats quote volume.
    5. 05Seniority is not a luxury — it is the minimum viable configuration.
    6. 06An agency that cannot make itself legible to the machines has no business selling that capability.

    “If it is not in the Canon, Crackle has not said it.”
