The Mega Analyzer already had a Legal-Site Readiness section. It runs when a page looks like a law firm and checks the things a partner actually cares about: is the attorney-advertising notice inline, does the bio carry Person+Attorney schema, does the practice page carry LegalService, is there a prior-results disclaimer. Those are all good checks. They are also all single-page checks. They answer "is this one page marked up correctly," and for a solo practitioner or a ten-lawyer boutique that's the whole question.
It is not the whole question for a multinational firm. I learned that auditing a global Am Law firm — over a thousand lawyers, offices on three continents, one of the deepest content libraries in its peer set — and finding that the single-page checks all passed their detection logic and then had nothing useful to say about the actual problem. The actual problem was scale and consistency: the firm published 3,680 thought-leadership pieces and not one carried Article schema; it had 1,093 attorney bios and not one carried Person schema; it ran sixteen offices in five countries and shipped zero hreflang. A check that asks "does this bio have Attorney schema?" reports a single miss. It doesn't tell you the miss repeats 1,093 times, or that the firm's entire international footprint is invisible to non-US search.
So I added a BigLaw layer. It extends the legal-readiness section and only fires when the page is both a legal site and looks like a large, multi-office firm — at least two foreign-city offices named in the page, or "over N lawyers" language, or "global firm" / "Am Law" markers. On a small single-office firm it stays quiet, because none of this applies to them.
What the BigLaw layer catches
Ranking-directory sameAs. For most businesses, the strongest external entity anchor is Wikipedia or Wikidata. For law firms it isn't — it's the directories. AI answer engines reconcile a firm's identity by traversing sameAs links to Chambers, Legal 500, Best Lawyers, Martindale-Hubbell, Super Lawyers, and Lawdragon. A firm with 127 Chambers-ranked lawyers that doesn't link to its own Chambers profiles in schema is leaving its single best authority signal on the table. The check looks for any of those directory hosts inside the page's JSON-LD and flags their absence on a firm that's clearly big enough to be ranked. It's the legal equivalent of a physician failing to link to their board certification.
Corpus-scale Article schema with author binding. A global firm's thought-leadership library is its primary AI-citation surface — thousands of client alerts, each 2,000 to 8,000 words of exactly the kind of substantive analysis answer engines prefer to cite. The generic "does this article have Article schema?" check passes on one flagship post and misses that the whole corpus is unmarked. The BigLaw check fires on any thought-leadership path (/publications/, /insights/, /blogs/, /news/, /perspectives/, /alerts/) that carries no Article/NewsArticle/BlogPosting, and separately flags the absence of an author binding — because the byline has to resolve to the writer's Attorney node by @id. Named-author content gets cited materially more often than content attributed only to "the firm," and that author-to-entity link is what makes it work.
Event schema plus a registration-capture loop. Firm CLE programs and webinars are the highest-intent business-development content a firm publishes — a registrant is a warm lead who raised their hand. The check fires on event-calendar paths that carry no Event schema, and the recommendation pairs the markup (startDate, eventAttendanceMode, organizer, performer → speaker bio @ids) with wiring the RSVP form into the firm's marketing CRM. Most firms do neither, so the warmest leads they generate are neither discoverable nor captured.
Multimedia schema and a transcript layer. Firms produce a lot of podcasts and videos that sit in opaque embeds — no VideoObject, no PodcastEpisode, no transcript. That content is simultaneously non-citable (an AI engine can't quote a video it can't read) and inaccessible (a screen-reader user can't either). The check flags media pages missing the schema, and the fix is one of the highest-leverage in the whole audit because a single transcript-and-schema pass improves AEO citability, ADA accessibility, and modern UX at the same time.
BreadcrumbList for deep hierarchies. BigLaw content lives three and four levels deep — /people/partners/..., /capabilities/practices/antitrust/..., /perspectives/publications/2025/.... Breadcrumb markup distributes link equity down into those deep pages and earns the breadcrumb rich result. The check fires on any page three or more path-levels deep with no BreadcrumbList, and the fix is a single global-layout change that every page inherits.
hreflang versus the actual office footprint. This is the check I most wanted. A generic hreflang audit fires on any site, which makes it noise. The BigLaw version weights it: it reads the office cities named on the page, and when it sees a genuine multi-jurisdiction footprint (London, Brussels, Shanghai, Amsterdam, Seoul) on a site shipping no hreflang, it says so with the offices named. A firm that advertises a global office list and then serves a 100%-English, hreflang-free site reads as US-only to every non-US search and AI engine. The leaders in this set ship a dozen hreflang annotations; the laggards ship zero, and the gap is invisible until you measure it against the office list.
Two advisory signals. When the page fingerprints an accessibility-governance tool (Siteimprove, AudioEye, accessiBe, UserWay) the analyzer adds a pointed note: verify the headshot grid actually passes WCAG 1.1.1, because a firm that pays for an accessibility watchdog and still ships missing-alt attorney photos is demonstrably on notice in ADA web-accessibility litigation — and a law firm is the worst possible defendant in that suit. And when it fingerprints enterprise search (Coveo, Algolia, Elastic) it notes the opportunity: that infrastructure is usually already RAG-capable, so a cited, no-advice "ask our publications" concierge is a UI layer away rather than a new system.
Why it's a separate layer, not a rewrite
The single-page legal checks are still right for what they do. The BigLaw layer is additive — it runs after them, on the same detected-legal-site signal plus a size gate, and it pushes its findings into the same readiness card. The design lesson is that "law firm" isn't one vertical. A storefront immigration practice and a multinational corporate firm fail in completely different ways, and an audit that treats them identically is useful to neither. The size gate is what lets the same tool say the right thing to both.
One compliance note that applies to every recommendation here: under ABA Model Rule 7.1 a schema field is a communication about the lawyer's services, so it carries the same liability as visible body copy. Factual markup — real addresses, jurisdictions of admission, practice areas, named-author attribution, award data linked to the rater's methodology — is safe and is exactly what wins E-E-A-T for YMYL-legal content anyway. Anything touching testimonials, results figures, or "best/leading/specialist" claims should go through the firm's own ethics counsel before it ships in an extractable field.
