What Is a Ghost Citation?
Short answer
A ghost citation is when an AI answer links your page as a source but never says your brand's name in the answer text. The term was coined by Kevin Indig, whose study with Semrush found 61.7% of AI citations work this way: your content used, your brand invisible.
Ghost Citation explained
Kevin Indig coined the term in his Growth Memo research and quantified it with Semrush in 2026: across 3,981 domain appearances spanning 115 prompts, 14 countries, and four AI engines, 61.7% of citations were ghost citations, a source link with zero brand mention in the answer text. Only 13.2% of appearances earned both the link and the name. The reader gets your information; the recognition goes nowhere.
The engines split sharply, which is why the metric matters per-platform. In the study, Gemini named brands in answer text far more readily than it linked them, while ChatGPT cited aggressively but mentioned sparingly, meaning a citation-count strategy can maximize exactly the engine least likely to say your name. Seer Interactive's analysis of hundreds of thousands of responses points at the mechanism: models often compose answers from learned brand knowledge first and attach retrieved sources after, so the mention depends on the model knowing your brand, beyond retrieving your page.
The fixes follow the diagnosis. Entity strength drives mentions, so the brand-building work throughout this glossary attacks the root. On-page, keeping your brand name adjacent to your citable facts and findings helps the name travel with the claim, and the study found comparative content earned 2.4 times more brand mentions than plain informational content. (Disambiguation: academia uses the same phrase for fabricated references in AI-written papers; this entry covers the AI-search meaning.)
In practice
Ghost citations are why I report mentions and citations as separate columns for every client, because a citation dashboard alone can show a thriving presence that no buyer ever associates with you. The pattern in the data matches what I see in audits: informational content gets used anonymously; content with a stance, a comparison, or a named finding gets attributed. It's one more argument for putting your name next to your numbers, and for building the entity so the model knows whose fact it borrowed.
Common misconception
People often assume being cited by AI means being seen by its users. Most citations never surface the brand's name in the answer, and the link-versus-mention gap is wide enough to require measuring both separately.
