How to get cited — 5 rules (Auspia + BotRank 2026)
- Be in top 20 first: 94% of AIO cites come from top 20; 99.5% from top 10 (SeoClarity) — SEO is entry ticket.
- Make passages extractable: Comparison tables, 3–7 numbered steps, bold-list anchors, FAQ H2 = question, definition-first 2 sentences — Gemini extracts passages, not narrative.
- Cover fan-out subqueries: Pages ranking for head + 1 fan-out subquery drive 51% of citations; 161% more likely — build clusters (pillar + 5–8 subpages).
- Unlinked mentions > links: Brand mentions r=0.664 vs links r=0.18 — YouTube (r 0.74, most-cited), Reddit 21%, LinkedIn for B2B, G2 for software.
- Freshness: Content updated <3mo is 3x more likely; 40–60% citations churn monthly — add visible Last Updated + dateModified.
Bottom line
- 48% prevalence, 2B users, -61% CTR, +120% cited lift — per BrightEdge/Google/Seer Jun 2026.

FAQ
Do I need llms.txt or special schema for AIO?
No — Google Jun 2026: no special files needed; but FAQPage/Article helps rich results and extraction.
Does ranking #1 guarantee citation?
No — overlap 76% (mid-2025) → 17–54% (early 2026 post-Gemini 3) — ranking gets you into pool, extractability gets you cited.
How fast can I get cited?
14–30 days after crawl if passage is clean + top 20 + freshness — continuous 3mo refreshes sustain it.
