How to Get Cited by AI Search: The Complete GEO/AEO Guide (2026)
(更新: )
An article that gets cited by AI search is one that is self-contained at the passage level, states specific facts with sources, and is made machine-readable with structured data. AI search engines ( Perplexity , ChatGPT Search, Google AI Overviews) don’t quote whole pages — they extract the one passage worth citing. This guide walks through how to write the passage that gets picked, from mechanics to measurement.
Bottom line (up front): Optimize for “extractability × authority × presence where AI looks,” not raw ranking. In the Princeton-led GEO study, adding sources lifted visibility by up to +40% and adding statistics by +37%, while keyword stuffing was −10% — actively harmful (source: Aggarwal et al., “GEO: Generative Engine Optimization,” KDD 2024).
Each AI search picks sources differently
Before optimizing, know that the play changes depending on which engine you target.
| Platform | How it works | Source-selection tendency |
|---|---|---|
| Google AI Overviews | Summarizes top-ranking pages | Strong correlation with classic rankings; SEO foundation matters |
| ChatGPT Search | Searches the web, cites sources | Pulls from beyond the top results; structure wins |
| Perplexity | Always shows source links | Favors authority, freshness, and structure |
| Gemini | Google index + Knowledge Graph | Entity recognition and structured data matter |
The key point: AI search competes on citation, not position. Even ranked on page 2–3 of traditional search, well-structured content can still get cited — it’s a different game.
The 3 principles of citable content
1. Structure (extractability)
AI extracts a passage, not a page. Lead each section with a direct answer, and write 40–60-word answer blocks that make sense without the surrounding context. Use tables for comparisons, numbered lists for steps, and headings that match how people phrase queries (“what is…”, “X vs Y”, “how to…“).
2. Authority (trust worth citing)
Sources, statistics, expert quotes, a named author, and an update date are the materials an engine uses to decide you’re citable. As the GEO study shows, sources +40%, statistics +37%, quotations +30%, with “readability × statistics” maximizing the effect. First-hand data (numbers you measured yourself) beats aggregated data.
3. Presence (be where AI looks)
AI cites third-party sources, not just your own site. One analysis found ~7.8% of ChatGPT citations come from Wikipedia and ~1.8% from Reddit. Build mentions on comparison articles, review sites, YouTube, and communities in parallel with your own site.
The 7 tactics, ranked by impact
Ordered by the visibility lift reported in the GEO study.
- Cite sources (+40%) — link claims to primary sources
- Add statistics (+37%) — “processes 10,000/sec,” not “fast.” With dates
- Add expert quotes (+30%) — named, with title; use “according to…” framing
- Authoritative tone (+25%) — assert from experience; avoid vague hearsay
- Improve clarity (+20%) — simplify hard concepts; one idea per paragraph
- Use technical terms (+18%) — the precise vocabulary of the field
- Don’t keyword-stuff (−10%) — the one clear negative. Don’t.
Technical setup: make it machine-readable
FAQPage structured data
“What is…?” and “How do I…?” Q&A is a format AI reuses directly in its answer template. This article defines its FAQ in frontmatter and emits FAQPage JSON-LD at build time (view the page source for application/ld+json).
Allow AI search crawlers in robots.txt
If you want to be cited, allow the crawl first. The middle ground is to block training-only crawlers (GPTBot, CCBot, Google-Extended) while allowing AI search crawlers (PerplexityBot, OAI-SearchBot, ClaudeBot) — avoid training use, keep citation.
llms.txt
Put an llms.txt at your site root with your site overview, author authority, and citation guidance. It works less as a ranking lever and more as a “how to cite us” guide.
Measure it: are you actually being cited?
You can only know if a tactic worked by tracking citations over time. Search your top 20 queries monthly across Perplexity, ChatGPT, and Google AI Overviews, and record whether you appear as a source — and which competitor pages get cited.
I track query-level citations continuously with my own AI-search measurement tool, AEO Console. The table below is a sample frame (※ plug in your own measured data here).

Common mistakes
- No date — undated content loses to dated content. Always show a last-updated date
- Gating content — AI can’t read gated pages, so it can’t cite them. Keep flagship content open
- No structured data — schema is reported to lift visibility 30–40%. No reason to skip it
- Only “we’re the best” — what gets cited is specifics like “customers saw a 3x improvement”
- Not measuring — you can’t improve what you don’t track. Monitor monthly
FAQ
What does it take to get cited by AI search?
Self-contained answer blocks (40–60 words), specific numbers with sources, FAQ-style Q&A, structured data (FAQPage/Article), and a robots.txt that allows AI search crawlers. These five move citation rates the most.
What is the difference between GEO, AEO, and LLMO?
They all mean optimizing to be cited by AI search and are essentially the same. GEO (Generative Engine Optimization) is the most established term; AEO and LLMO are synonyms.
Can traditional SEO and GEO coexist?
Yes. Solid traditional SEO is the foundation; GEO adds passage-level extractability and citation-worthy authority on top.
How do I check whether Perplexity is citing me?
Search your target keyword in Perplexity and check whether your site is in the Sources. Tracking your top 20 queries monthly surfaces where to improve.
