{"title":"Google rankings and AI citations: what the research shows","url":"https://outwrite.ai/research/google-rankings-ai-citations","type":"Research review","modified":"2026-10-26T16:00:00Z","methodology":"We selected primary empirical work comparing organic visibility, AI source selection, brand naming and clicks, plus official measurement guidance. We checked the original write-ups and the preprint’s methods and limitations. The comparison separates platform, unit, denominator, sample and measurement period. We did not combine study estimates or collect a new answer dataset. The chart reproduces the cited organic-only percentages; the worked denominator example is hypothetical. This is a focused editorial review, not a systematic review or meta-analysis.","disclosure":"outwrite.ai sells content automation and AI visibility software. This report uses AI-assisted source discovery, drafting and editorial checks, with the cited findings checked against their original sources.
