Do Statistics Really Improve AI Citations?

Yes. The foundational GEO research paper by Aggarwal et al. (KDD 2024) tested nine optimization methods across thousands of queries and found that adding statistics, quotations, and cited sources lifted a page's visibility in generative answers by 30-40%, while keyword stuffing produced no measurable gain. Numbers give retrieval systems concrete, matchable anchors and signal authoritativeness.

Why numbers outperform adjectives

Embedding models match meaning, and a specific figure carries far more distinguishing signal than a qualifier. "Deliverability of 82%" occupies a precise point in vector space; "high deliverability" is diffuse and matches almost nothing. Engines also weigh statistics as trust signals — a passage with a sourced number reads as researched, which matters in the E-E-A-T-adjacent scoring that answer engines apply before quoting a source. This is why statistics-heavy pages are among the most-cited content types across ChatGPT, Perplexity, and Google AI Overviews.

Three honest ways to raise evidence density

Original data is the strongest of the three because it's uniquely yours and can't be duplicated by competitors. If you lack a research budget, product telemetry, support-ticket counts, and customer surveys are cheap sources — see how to add original data.

The honesty rules that keep citations

Evidence density only helps if the evidence is real. Attach a named source and a year to every statistic. Never round a range into a false precision. When you don't have a number, describe the mechanism ("adding a benchmark makes the passage quotable") rather than manufacturing one. Engines increasingly cross-reference claims across sources, and a fabricated stat that can't be corroborated gets the whole page demoted.

Add three verifiable facts per page as a floor, front-load them near the answer, and route measurement of the payoff through your GEO tracking so you can see which evidence-rich pages actually start earning citations. Curated, sourced numbers also make a natural statistics page that becomes a citation magnet in its own right.
