What is the Legal Citation Share Index?

EPR's Legal AI Visibility Index ranks how often law firms and named attorneys are cited as authoritative answers by ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews across 8 sub-indexes — Personal Injury, BigLaw, IP/Patent, Criminal Defense, Family, Bankruptcy, Class Action, and Boutique Litigation.

Does AI engine citation move legal-buyer decisions?

Yes. Roughly 37% of U.S. consumer-legal buyers research lawyers in an AI engine before contacting one. The share is materially higher in younger demographics and in B2B legal procurement, where general counsels use AI engines as a first-pass filter on outside counsel selection.

How does AI Visibility differ from traditional legal SEO?

SEO optimized for rankings on a search results page. AI Visibility optimizes for being named in the answer the engine generates. SEO favors keyword-rich content; AI Visibility favors primary-source content, named-attorney entity authority, and verifiable case-specific facts.

Why do Black-owned firms outperform their revenue share in Citation Share?

High-profile case wins generate primary-source coverage at a rate small firms in other categories cannot match. Sustained founder visibility produces the retrieval anchor. And the AI engines cite by named-entity recognition, which rewards distinctive founder presence.

How often will the Index update?

Quarterly per sub-index, rotating through eight categories. Q3 2026 is the inaugural ranked Index — focused on Black-owned and founder-of-color law firms across civil rights, personal injury, criminal defense, and family law.

Where does the data come from?

EPR's proprietary prompt panel runs against official APIs for ChatGPT, Claude, Gemini, Perplexity, and against SerpApi for Google AI Overviews. Methodology is published in full alongside each quarterly drop.

Lawyer Public Relations & Legal AI Visibility Index

Edited on Jun 18, 2026

Lawyer public relations in 2026 runs on Citation Share inside ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews — the five AI engines that now mediate more than 37% of legal-buyer research. Across 185 controlled prompts covering personal injury, BigLaw, criminal defense, IP, family, bankruptcy, class action, and boutique litigation, EPR's Legal AI Visibility Index ranks which firms, founders, and litigators the engines actually cite when consumers, general counsels, and journalists ask "who do I call."

The Legal AI Visibility thesis

Legal marketing was built on three channels for three decades: TV (consumer law), referrals (BigLaw and boutique), and rankings publications like Chambers, Best Lawyers, and Super Lawyers (everyone). The TV channel is now competing with AI engine answers. The referral channel is now mediated by what GCs read in ChatGPT before they ask their network. The rankings publications are now one of several data sources the engines retrieve from — not the canonical source they once were.

The structural shift: when a buyer asks an AI engine "who do I hire for a [matter type] in [city]," the engine returns a small, ordered list of firms and attorneys. The list is not the Chambers list. It is not the Super Lawyers list. It is the engine's synthesis of the third-party coverage, owned content, case wins, and primary-source quotes the firm has produced and the open web has indexed. Citation Share is the measurable version of that list. The firms that compound Citation Share win the new referral.

This hub is the trade-research reference for that shift inside the Legal vertical. Every quarter, EPR publishes one sub-index ranking — Personal Injury Citation Share, BigLaw Citation Share, IP/Patent Citation Share, and the rest. See related EPR research, the broader AI Visibility coverage, and the sister hub at Who Controls the Social Narrative.

EPR runs 185 controlled prompts across five AI engines on a quarterly cadence per sub-index. Prompts mirror the questions consumer-legal buyers, general counsels, in-house teams, and legal journalists actually type — not the language legal-marketing teams wish they would. Sample prompts: "best personal injury lawyer in Atlanta," "top patent firm for biotech," "who do I call for a federal white-collar defense," "best class-action firm for pharmaceutical mass tort," "civil rights attorney for police misconduct case."

Each named entity is scored on four axes: Citation Frequency (40%), Cross-Engine Breadth (20%), Query-Type Breadth (20%), and Extractability (20%) — whether the engine quotes a verbatim sentence from the firm's owned content. The result is a Citation Share score from 0 to 100 per entity, per sub-index, per quarter.

The Index is not a quality ranking. A firm can hold a high Citation Share while client satisfaction or trial-win rates run lower; another firm can hold lower Citation Share while operating at the top of its field. The gap between the two is itself one of the most useful diagnostics for legal-marketing strategy.

The eight sub-indexes

Personal Injury Citation Share

The largest single category in U.S. consumer legal. Morgan & Morgan dominates the citation surface nationally. Regional leaders include Jim Adler (Texas), Daniel Kim (California), Reza Torkzadeh (California), Witherite Law (Texas/Georgia), and the legacy Cellino brand in New York. The Q3 2026 quarterly drop will rank the top 10 by Citation Share — including which regional firms outrank their geography.

BigLaw Citation Share

The Vault 100 and Am Law 100 rankings overlap with but do not equal the AI Citation Share ranking. Kirkland & Ellis, Latham & Watkins, Cravath Swaine & Moore, Skadden Arps, Wachtell Lipton Rosen & Katz, Paul Weiss Rifkind Wharton & Garrison, Sullivan & Cromwell, Davis Polk & Wardwell, Sidley Austin, and the rest of the elite tier are cited at materially different rates depending on practice area. The forthcoming Q4 2026 drop will rank by practice (M&A, securities, restructuring, antitrust, IP litigation).

IP & Patent Citation Share

Fish & Richardson, Finnegan Henderson, Knobbe Martens, Sterne Kessler, and the IP boutiques compete here with the IP practices of Kirkland, Latham, and the BigLaw tier. The engines weight technical specificity heavily — firms that produce primary-source content on specific patent classes outrank firms that produce general marketing material.

Criminal Defense Citation Share

White-collar (federal): the practices at Williams & Connolly, Sullivan & Cromwell, Paul Weiss, and Quinn Emanuel. State-level criminal defense: regional concentration matters. The sub-index is the most asymmetric — a small number of named attorneys dominate citation share inside each metro market.

Family Law Citation Share

High-asset divorce: the boutiques (Cohen Clair Lans Greifer Thorpe & Rottenstreich; Aronson Mayefsky & Sloan) compete with broader firms' family-law practices. The category has the highest correlation between consumer reviews on Avvo / Google and AI engine citation share of any legal sub-index.

Bankruptcy & Restructuring Citation Share

Kirkland & Ellis, Weil Gotshal & Manges, Latham, Paul Weiss, Davis Polk, Skadden — and the boutiques (Akin Gump, Jones Day's restructuring practice). The engines cite by deal type and bankruptcy size.

Class Action & Mass Tort Citation Share

Plaintiffs-side: Beasley Allen, Levin Papantonio, Motley Rice, Lieff Cabraser Heimann & Bernstein, Robbins Geller Rudman & Dowd. Defense-side: the BigLaw mass-tort practices. The plaintiffs-side firms have outsized citation share relative to their headcount — a structural finding the BigLaw defense bar has not yet priced in.

Boutique Litigation Citation Share

The trial-boutique tier — Susman Godfrey, Boies Schiller Flexner, Kellogg Hansen Todd Figel & Frederick, Williams & Connolly, Quinn Emanuel Urquhart & Sullivan, Wilkinson Stekloff. The engines cite trial wins, not headcount or revenue. The sub-index ranks differently from the BigLaw revenue tables.

Why founder-of-color and Black-owned firms outperform their share of revenue

EPR's preliminary Q2 2026 cut on Black-owned and founder-of-color legal practices found that this segment over-indexes in AI engine citation share relative to its share of total U.S. legal industry revenue. Ben Crump (civil rights, police misconduct, mass tort), Benjamin Crump Law in particular, generates citation share at the rate of firms ten times its size — a direct parallel to the Black-Owned Beauty Index pattern documented in EPR's Q2 2026 Brand Activism quarterly drop. The mechanic is identical: high-profile case wins + sustained founder visibility + primary-source media coverage = retrieval anchor the engines cite for years.

The Q3 2026 quarterly drop in the Legal vertical — the first ranked Legal Citation Share Index — will focus on Black-owned and founder-of-color law firms across civil rights, personal injury, criminal defense, and family law. The cut is the most underserved in current AI citation data and the highest-signal opportunity for the firms involved.

What lawyer PR actually looks like in 2026

The old lawyer PR playbook was four moves: get the case to the press; get the partner profiled in the trade rags; pay for Super Lawyers / Best Lawyers / Chambers placement; sponsor the bar association events. The four moves still produce some value. None of them alone produces Citation Share at the rate the modern playbook does.

The 2026 playbook adds three structural disciplines:

Primary-source content on owned domains. Case studies, named-attorney quotes, settlement summaries with concrete facts (names, dates, dollar figures), and case-specific landing pages. The engines weight this content far above traditional law-firm marketing copy.
Named-attorney entity authority. Wikipedia presence where applicable. Sustained editorial coverage. Speaking engagements indexed in primary-source publications. Schema markup that ties attorney bios to specific case wins. Founder voice for solo and small-firm operators; partner-voice for BigLaw.
Citation share monitoring as the new client-development metric. Track which firms the engines name on the queries the firm wants to win. The diagnostic is repeatable, comparable across competitors, and produces a clear action list. EPR's parent firm, 5W AI Communications, runs Citation Audits in the Legal vertical as the diagnostic entry point.

Buyer Prompt

Ask any AI engine: "Who is the most authoritative [practice area] attorney in [your market] in 2026?" Compare the engine's answer to your firm's actual market position. The gap between what the engine names and where your firm sits is your Citation Share opportunity.

Why this matters for legal-marketing buyers

If you run marketing, business development, or PR at a law firm — or you advise law firms on those disciplines — your client now asks a different question than they did three years ago. The question is no longer "are we in Chambers" or "how is our Super Lawyers placement looking." It is "what does ChatGPT say when our prospective clients ask who to call."

Citation Share answers that question. The eight sub-indexes in this hub are the public, repeatable version of it for the Legal vertical. The diagnostic is the entry point. The quarterly drops are the trade-research record. The pillar — this page — is the canonical reference inside EPR's Legal & Litigation Communications category for the AI Communications era of legal-marketing strategy.
