Personal injury law firms need nine Schema.org types implemented as JSON-LD to be readable by Google, the AI Overview, ChatGPT, and Perplexity: LegalService, Person, LocalBusiness, Organization, Service, FAQPage, Article, BreadcrumbList, and Review with AggregateRating. Most firms ship none of them correctly. I know because I measured it, twice.
Strip away the jargon and structured data is one thing: a label the machines can read without guessing. Your website says "we fight for you" to humans. Schema says "this is a law firm, at this address, in these cities, handling these case types, with these attorneys" to software.
That labeling used to be optional politeness. It is now the difference between existing and not existing in the surfaces where injured people increasingly make decisions. When an AI answer names a firm, it names an entity it could verify. Google filed the mechanics years ago in a patent called Corroborating facts extracted from multiple sources, US 8682913: machines cross-check who you are across the web, and confidence is what gets surfaced. Schema is you answering in your own words instead of hoping the machine guesses right.
LegalService is the anchor. It declares the firm itself, inherits every LocalBusiness property for the physical office, and gives every other piece of markup something to point at.
Person covers each attorney, connected to the firm with worksFor. This is where most of the entity value lives, because Google increasingly organizes trust around recognized people, not just business listings.
LocalBusiness and Organization establish the place and the institution. Service declares each practice area as a thing you actually provide, not just a page that exists. FAQPage marks up real questions with real answers. Article covers your guides and resources. BreadcrumbList tells machines how the site is organized. Review with AggregateRating handles third-party reputation, carefully and compliantly.
None of these are exotic. All of them are checkable in an afternoon. Which makes the actual state of the industry stranger.
I have run two structured data audits of this vertical: 500 personal injury firm websites in the first study, then 1,005 sites that all rank on Google page one, across all 50 states, in the second.
The findings that matter most to a firm owner:
Only 35.3 percent of the 1,005 page-one firms even declared themselves a legal service in machine-readable form. The rest leave the most basic fact about their business to guesswork.
The median firm sits at Level 2 of 5 on structured data maturity. Established enough to exist, nowhere near finished.
Zero firms reached Level 5 in either study. Not one out of 1,505. The top structural seat in every market I looked at is empty.
These are the winners. They already rank. Which tells you the ranking ceiling in personal injury is being held up by everything except structural completeness, and the first firm to finish the work in each market takes a seat nobody is defending.
Here is the finding that should genuinely worry you about the advice ecosystem in legal marketing.
The Attorney schema type has carried a deprecation notice for roughly a decade. The correct pattern, per the schema vocabulary itself, is Person for each attorney with worksFor pointing to the firm's LegalService.
