GEO finding: Statistics Addition is the #2 tactic at +31%

Claim: Statistics Addition (inserting concrete numbers, percentages, dates into content) lifted AI-response visibility by +31% on Position-Adjusted Word Count in the Princeton GEO paper — second only to Quotation Addition (+41%).

Source: Aggarwal et al., arXiv:2311.09735 v3, Table 6. See Princeton GEO paper (Aggarwal et al., KDD '24) — the foundational generative engine optimization study.

Confidence: Verified (primary).

Practical implication for Candid content: Every claim that can carry a number (date, percentage, count, currency) should carry one. Vague "many businesses" / "most of the time" hedging is exactly what the paper measured as low-lift.
