What is AI citability?
AI citability is how likely an AI search engine is to quote your page when it answers a question. It is a new discipline because AI answers often resolve a query without a click, so being the source an engine names, not just a page it ranks, is what earns you visibility and trust. Rubric estimates that likelihood as a score from 0 to 100.
- →AI citability is the likelihood that an AI engine quotes your page when it answers a question, as distinct from where you rank in a list of links.
- →It matters because AI answers are often zero-click: the engine writes the answer and names a few sources, so being named is the win.
- →Rubric estimates citability with a 0 to 100 score built from 44 checks across three pillars: Known, Findable and Trusted.
What is AI citability?
AI citability is how ready a page is to be quoted by an AI search engine such as ChatGPT, Perplexity, Google AI Overviews, Gemini, Microsoft Copilot or Claude. When one of these engines answers a question, it retrieves a handful of candidate pages, lifts the passage that best answers the query, and names some of those pages as sources. A citable page is one that is easy to find, easy to lift from, and trustworthy enough to name.
Citability is a property of the individual page, not of your whole domain. Two pages on the same site can differ widely: one can be highly citable while the page next to it is answered around and never named.
How is AI citability different from ranking?
Ranking is about position in a list of links; AI citability is about being the source an engine repeats in its own answer. The two overlap, because a page an engine can crawl and understand tends to do well at both, but they reward different things and you measure them differently.
| Classic ranking (SEO) | AI citability | |
|---|---|---|
| The unit | A page's position in a list of links | Whether a page is quoted in a generated answer |
| The user action | The user scans results and clicks | The engine answers inline, often with no click |
| What wins | Relevance, authority and links | A liftable answer, a clear entity, sourced evidence |
| Where you appear | The results page | Inside the answer, as a named source |
| How you measure it | Rank position and clicks | Citations, with citability as a leading estimate |
Why does AI citability matter now?
AI citability matters now because a growing share of searches end without a click. When an engine writes the answer itself and names two or three sources, the pages it does not name are effectively invisible, even ones that would have ranked on the first page of results. AI Overviews answers run about 67 words at the median (Pew, 2026), which is enough to satisfy the user and short enough that only the most liftable sources get named. Being one of those named sources is the new front page.
What makes a page citable?
Three things make a page citable, and they map onto Rubric's three pillars. An engine has to know who you are, find a clean answer, and trust the page enough to name it.
- Known is discovery. Can an engine resolve who published the page and attribute a quote to you. This is entity clarity, schema and internal linking.
- Findable is retrieval. Can an engine locate a clean, liftable answer near the top of the page. This is answer-first openers, question-shaped headings and self-contained sections.
- Trusted is citation. Is the evidence strong enough for an engine to put its name next to yours. This is sourced statistics, named authors and freshness.

How Rubric measures citability
Rubric measures citability as an estimated score from 0 to 100, per page. The site score it shows is the median of your page scores, so one strong page cannot hide twenty weak ones. Seventy is the line: at or above 70 a page is treated as quotable, and below it a page tends to be answered around rather than named.
The score is an estimate from on-page, structural and technical signals. It does not count citations you have already earned; it predicts the citability that earns them. To learn how to read the number and decide what to fix first, start with reading-your-citability-score.
