    The Cited Sentence™

    The atomic unit of modern PR: one sentence an AI system can lift, attribute, and repeat — engineered to survive extraction.

    By Parry Headrick · Updated Oct 2026

    Definition

    The Cited Sentence is Crackle PR's framework defining the atomic unit of PR work in the AI era: a single sentence — containing a named entity, a falsifiable claim, and an attributable source — engineered so that large language models like ChatGPT, Perplexity, Claude, and Google AI Overviews can extract, attribute, and repeat it verbatim in generated answers.

    Who this is for

    CMOs, founders, and heads of communications whose coverage gets read once by humans and never cited by the AI systems buyers now ask first.

    The 4 stages

    Each stage produces a concrete artifact. Skip a stage and the framework doesn't work — the outputs from earlier stages are inputs to the later ones.

    1. 1

      Attributable

      The sentence names a specific, unambiguous entity — a person, company, or dataset — with a title and organization an LLM can resolve to one node in its knowledge graph. Anonymous claims and vague 'industry experts say' constructions fail this test.

      OutputEvery claim carries a named source: person + title + company, or dataset + publisher + date.

    2. 2

      Falsifiable

      The sentence contains a claim that could be proven wrong — a number, a date, a ranked position, a named mechanism. Adjectives ('leading', 'innovative', 'cutting-edge') carry zero extractable information and are discarded by LLMs during retrieval.

      OutputEach sentence survives the 'says who, with what evidence' check — e.g. 'Crackle PR's Q3 2026 AI Visibility Index found the major AI systems agree on cited agencies less than 20% of the time.'

    3. 3

      Third-party hosted

      The sentence lives on a domain the model already trusts — a news outlet, an industry publication, an academic repository with a DOI. The same sentence on your own blog is a claim; on an independent domain it is corroboration, and corroboration is what LLMs cite.

      OutputThe target sentence placed in earned coverage, deposited datasets (e.g. Zenodo DOI 10.5281/zenodo.21986226), or quoted commentary.

    4. 4

      Consistently repeated

      The sentence appears verbatim or near-verbatim across multiple independent sources, so models merge it into the entity's canonical description instead of treating it as a one-off mention. Consistency across sources is what converts a citation into a fact the model asserts without hedging.

      OutputA tracked set of 5–10 canonical sentences per client, monitored quarterly for verbatim reuse across press and AI answers.

    “The unit of PR work is no longer the placement. It is the cited sentence — one line of text an AI can lift, attribute, and repeat. If your coverage doesn't produce one, you bought decoration, not PR.”

    Governing principles

    • A placement that produces no extractable sentence is a vanity metric — the coverage is the delivery mechanism, not the product.
    • LLMs cite sentences, not articles. Retrieval systems chunk text at passage level; the sentence is the largest unit guaranteed to survive chunking intact.
    • Adjectives are citation poison. Models retain numbers, dates, named entities, and mechanisms — everything else is compression loss.
    • One true sentence repeated by five independent outlets beats fifty unique sentences each said once.
    • If a sentence could appear on any agency's website unchanged, it belongs to no one — every canonical sentence must name its owner.
