AI citations
An AI citation is a link an AI system shows as a source for the answer it wrote. Joe Ashta, a GEO / AEO consultant for law firms, counts citations on the BigLaw GEO Leaderboard and keeps them separate from every other visibility number, because a citation proves one specific thing and is often read as proving more. This page states what a citation is on each surface, what it does and does not prove, why it is the most available metric, and what kind of page earns one.
What a citation is on each surface
The glossary definition holds across platforms: a link displayed as a source. The form differs.
| Surface | How the citation appears |
|---|---|
| ChatGPT with search | Numbered or named source chips inside the answer and a sources panel listing the pages retrieved for it |
| Claude with web search | Inline links in the answer text and a list of sources beneath it |
| Gemini | Source links attached to passages, expandable under the answer |
| AI Overviews | A set of link cards beside or below Google's summary, above the standard results |
| AI Mode | Link cards and inline references inside the conversational answer, refreshed as the conversation continues |
On every surface the citation is a link to a page. It is never a statement about the firm that owns the page.
What a citation proves
A citation proves that the page was retrieved for the question and used in writing the answer. That is a real event. It means the page cleared grounding and was weighted enough to be kept. A firm whose pages are cited has evidence that the system can read its site and finds parts of it useful.
A citation does not prove that the firm was named. It does not prove the firm was recommended. It does not prove the buyer saw the firm's name at all. A criminal defence firm in Vancouver can be cited under an answer that explains the immediate roadside prohibition scheme, because its explainer page is clear, while the same answer names two other firms as the ones to call. The cited firm supplied the background. The named firms got the client.
The AI search visibility page covers why a firm can be cited often and named rarely. The short version: citation is a property of a page, and naming is a property of an entity.
Why citations are the most available metric
Citations are links, and links are countable by machine. A data vendor such as Ahrefs can crawl AI answers at scale, record which pages were linked as sources, and report the counts per site. That makes citations broad, inexpensive and third-party, and it makes them the number most firms will see first, because it is the number vendors can sell.
The BigLaw GEO Leaderboard uses citations for that reason. It ranks 118 US law firms by AI search citations reported by Ahrefs, and it is labelled as a vendor-reported instrument. It shows which firms' sites the platforms read. It does not show which firms the platforms tell a buyer to hire, and it is labelled that way wherever this site mentions it.
What kind of page gets cited
Across surfaces the pages that earn citations share four properties.
- Specific. The page answers one question in full. A page on the penalties for a first impaired driving offence in British Columbia is cited for that question. A page titled "Criminal Defence Services" is cited for nothing.
- Quotable. The answer is stated in a sentence or two that can be lifted whole. Systems prefer passages they can attribute without rewriting.
- Dated. The page shows when it was published and when it was last reviewed. Legal information ages, and a system choosing between two explanations of the same rule will prefer the one that says it is current.
- Attributable. The page names its author, the author is a lawyer, and the firm and its location are stated on the page and in its structured data. A passage with a named source is easier to cite than an anonymous one.
These are page-level properties. A firm can produce them on its own, which is why citations are the earliest visibility a firm can earn and the easiest to earn without any change to how the firm is perceived.
The gap between citation and mention
A mention is the firm named in the answer text. A citation is a link beneath it. The two are produced by different evidence. A citation follows from a good page. A mention follows from the system being confident about the firm as an entity: its name, its place, its practice, and the outside records that agree. A firm can hold either without the other.
The gap is where most law firm AI search work sits. Firms that have already been cited have proven their pages can be read. What remains is the entity work that turns a read page into a named firm, and the entity record on this site is a worked example of that second job applied to one person.
