AI citability scoring and optimization. Analyzes web page content to determine how likely AI systems (ChatGPT, Claude, Perplexity, Gemini) are to cite or quote passages from the page. Provides a citability score (0-100) with specific rewrite suggestions.
AI language models cite passages that meet specific structural criteria. Research from Princeton, Georgia Tech, and IIT Delhi (2024) found that GEO-optimized content achieves 30-115% higher visibility in AI-generated responses. The key finding: AI systems preferentially extract and cite passages that are 134-167 words long, self-contained (understandable without surrounding context), fact-rich (containing specific statistics, dates, or named entities), and directly answer a question in the first 1-2 sentences.
This is fundamentally different from traditional SEO copywriting, which optimizes for keyword density and user engagement metrics. GEO citability optimizes for extractability -- the ease with which an AI system can pull a passage from your content and present it as a direct answer.
This measures whether content contains clear, quotable answer passages that AI systems can extract verbatim.
Scoring Criteria:
| Score | Criteria |
|---|---|
| 90-100 | Every major section opens with a 1-2 sentence direct answer. Uses "X is..." or "X refers to..." patterns. First 40-60 words of each section can stand alone as a complete answer. |
| 70-89 | Most sections have clear answer openings. Some definition patterns present. Answers are identifiable but may need minor context. |
| 50-69 | Some sections have answer-like openings but many bury the answer in the middle or end of paragraphs. Few explicit definition patterns. |
| 30-49 | Answers are generally buried in long paragraphs. No consistent definition patterns. Content is narrative-driven rather than answer-driven. |
| 0-29 | No identifiable answer blocks. Content is entirely narrative, conversational, or fragmented. AI would struggle to extract any quotable passage. |
What to look for:
High-citability example:
Content delivery networks (CDNs) are distributed server systems that cache and serve
web content from locations geographically close to end users. A CDN reduces latency
by 50-70% on average by serving assets from edge servers rather than a single origin
server. The three largest CDN providers as of 2025 are Cloudflare (serving approximately
20% of all websites), Amazon CloudFront, and Akamai Technologies.
Word count: 58. Self-contained: Yes. Facts: 3 specific data points. Definition pattern: Yes.
Low-citability example:
If you've ever wondered why some websites load faster than others, the answer might
surprise you. There's this amazing technology that has been around for a while now.
It's changed the way we think about web performance. Let me explain how it works and
why you should care about it for your business.
Word count: 52. Self-contained: No (no topic identified). Facts: 0. Definition pattern: No.
This measures whether individual passages can be extracted and understood without needing the surrounding content.
Scoring Criteria:
| Score | Criteria |
|---|---|
| 90-100 | 80%+ of content blocks are fully self-contained. Each passage names its subject explicitly. No reliance on pronouns referencing earlier content. Contains specific facts within the passage. |
| 70-89 | 60-79% of content blocks are self-contained. Most passages name their subject. Occasional pronoun references that require context. |
| 50-69 | 40-59% of content blocks are self-contained. Mixed use of explicit subjects and pronouns. Some passages require reading prior sections. |
| 30-49 | 20-39% of content blocks are self-contained. Heavy reliance on pronouns and contextual references. Most passages need surrounding text. |
| 0-29 | Under 20% self-contained. Content reads as a continuous narrative where extracting any paragraph loses meaning. |
Self-containment checklist for each passage:
This measures the structural formatting that helps AI systems parse and segment content.
Scoring Criteria:
| Score | Criteria |
|---|---|
| 90-100 | Clean H1 > H2 > H3 hierarchy. Question-based headings for informational content. Short paragraphs (2-4 sentences). Tables for comparisons. Ordered lists for processes. Unordered lists for features/options. |
| 70-89 | Good heading hierarchy with minor skips. Some question-based headings. Mostly short paragraphs. Some use of tables and lists. |
| 50-69 | Heading hierarchy present but inconsistent. Few question-based headings. Mix of short and long paragraphs. Limited tables/lists. |
| 30-49 | Minimal heading structure. No question-based headings. Long paragraphs dominate. Rare use of tables/lists. |
| 0-29 | No heading structure or severely broken hierarchy. Wall-of-text paragraphs. No tables or lists. |
Structural best practices for AI citability:
This measures the presence of specific, verifiable data points that AI systems prioritize when selecting citation sources.
Scoring Criteria:
| Score | Criteria |
|---|---|
| 90-100 | 5+ specific statistics per 500 words. All claims backed by named sources or dates. Uses exact numbers (not "many" or "several"). Includes percentages, dollar amounts, timeframes, and named studies. |
| 70-89 | 3-4 statistics per 500 words. Most claims have sources. Mostly specific numbers with occasional vague quantifiers. |
| 50-69 | 1-2 statistics per 500 words. Some claims sourced. Mix of specific and vague numbers. |
| 30-49 | Less than 1 statistic per 500 words. Few sourced claims. Predominantly vague quantifiers. |
| 0-29 | No statistics. No sourced claims. All quantifiers are vague ("many," "most," "a lot"). |
What counts as a statistic:
What does NOT count:
This measures whether the content provides information that AI systems cannot find elsewhere, making it a necessary citation source.
Scoring Criteria:
| Score | Criteria |
|---|---|
| 90-100 | Contains first-party research, proprietary data, original surveys, or unique datasets. Presents analysis or insights not found on any other page. Clear methodological descriptions. |
| 70-89 | Contains some original insights or unique analysis of existing data. Offers a distinct perspective with original examples. |
| 50-69 | Mostly synthesizes existing information but adds some unique commentary or examples. |
| 30-49 | Largely derivative content that restates common knowledge with minimal original contribution. |
| 0-29 | Entirely derivative. All information is available (often verbatim) on higher-authority sources. |
Signals of unique content:
For each content block, calculate:
Block Citability Score = (Answer * 0.30) + (SelfContain * 0.25) + (Structure * 0.20) + (Stats * 0.15) + (Unique * 0.10)
For each block scoring below 60, generate a specific rewrite suggestion:
