GEO finding: Quotation Addition is the top-performing tactic at +41% on Position-Adjusted Word Count
Claim: Among the 9 tactics tested in the Princeton GEO paper, Quotation Addition was the best-performing single method, lifting visibility by +41% on Position-Adjusted Word Count (Table 6). Statistics Addition was second at +31%, Cite Sources third at +28%, Fluency Optimization at +28%. Combined Fluency + Statistics reached +35.8%.
Quote (paper abstract / §1): "Including citations, quotations from relevant sources, and statistics can significantly boost source visibility, with an increase of over 40% across various queries."
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 read of paper v3).
Important attribution correction: Many SEO industry writeups credit Statistics Addition with the +41% number. The paper itself names Quotation Addition as the +41% method on PAWC. Brief 1 of the Candid research series flags this conflict explicitly. Brief 2 inherits the industry confusion. Use the paper, not the SEO blogs.
