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.

Fluency Optimization
Fluency 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 for better readability, clarity, and flow, scoring PAWC 25.1 vs baseline 19.5 (~29% relative gain). The paper also found that combining Fluency Optimization with Statistics Addition outperforms any single GEO method by more than 5.5%, the strongest of the pairwise combinations measured in its top-4 combination experiment.

Quotation Addition
Quotation Addition is the Aggarwal et al. 2023 GEO paper's top-performing source-content modification method (PAWC 27.8 vs baseline 19.5, ~43% relative gain): actively rewriting content to include sourced direct quotations from authorities. The practitioner discipline framing extends the paper's one-shot intervention into a habitual writing technique.

Statistical Density
Statistical density is a practitioner-coined shorthand for the content property that the Aggarwal et al. 2023 GEO paper's 'Statistics Addition' method tries to increase: presence of verifiable statistics, dates, and numerical claims. The term itself and any specific ratio definition are practitioner-derived, not paper measurements.
