Authoritative Statement Strength
Authoritative statement strength is widely recommended in SEO content as a citation lever. Aggarwal et al. 2023's GEO paper tested 'Authoritative' tone as one of nine content-modification methods and reported verbatim 'to the contrary we find no significant improvement', a null finding rather than a modest lift. The +11.8% relative gain in raw PAWC numbers (21.8 vs baseline 19.5) was not framed by the paper as statistically meaningful. The folk wisdom that authoritative tone is a primary AI-citation lever has no empirical support in the only public benchmark; it is paper-verbatim null.

Cite Sources Optimization
Cite Sources Optimization is one of the four top-performing source-content modification methods in Aggarwal et al. 2023's GEO paper. The method actively rewrites content to add inline source citations for claims made, scoring PAWC 24.9 vs baseline 19.5 (~28% relative gain). The practitioner discipline framing extends the paper's one-shot intervention into a habitual writing technique.

Hybrid retrieval
Hybrid retrieval combines lexical (keyword) search with semantic (vector embedding) search in a single ranking pipeline. It is a common production pattern in modern retrieval and RAG systems and is likely used in some form by many AI-search products, though individual vendors rarely disclose their full retrieval architecture.

Passage-level optimization
Passage-level optimization is the practice of structuring individual paragraphs and sections so they remain understandable when extracted independently. It is a content-design discipline derived from how retrieval-augmented and AI-search systems often operate over passages or chunks rather than whole documents.

Sub-document retrieval
Sub-document retrieval is the practice of indexing and retrieving passages or paragraphs rather than whole documents. It is a common retrieval pattern in RAG and AI-search systems, especially when long documents need to be matched against specific user queries.

Citation precision and recall
Citation precision is the fraction of citations in an AI engine's response that actually support the sentence they are attached to. Citation recall is the fraction of generated sentences that are fully supported by their citations. Both are model-behavior metrics, not publisher-visibility metrics: they measure how faithfully an AI engine uses the sources it cites, not how often a publisher's content appears as a source.

Sycophancy vs cite-able fact
Sycophancy is the LLM failure mode of producing agreeable, hedge-laden, or context-flattering responses at the expense of factual specificity. Cite-able fact production is a separate content-writing pattern that emphasizes specific, attributed, falsifiable claims. The two are not strict opposites, but understanding both is useful for AI-search content writers.
