The Complete Guide to JSON-LD Schema for Law Firms
How law firms can use JSON-LD schema for SEO and AI search, including LegalService, attorney Person, FAQ, and Article markup with examples.
In today's digital landscape, making your content understandable to AI systems and search engines is crucial for visibility and engagement. JSON-LD (JavaScript Object Notation for Linked Data) schema markup provides explicit signals about your content's meaning and purpose, helping AI systems better understand context and relationships.
For law firms, schema is one of the clearest ways to tell Google exactly who you are: the firm's name, office locations, practice areas, and the attorneys behind them. That clarity supports local rankings, rich results, and how AI search tools describe your firm. This guide covers the core schema types, then shows how to apply them on a law firm website, including LegalService and attorney markup.
What is JSON-LD Schema?
JSON-LD schema is a method of structured data markup that uses a standardized vocabulary to describe content on web pages. Unlike other markup formats, JSON-LD is embedded as a script tag in your HTML, making it clean and separate from your visible content.
Why JSON-LD Schema Matters for AI and SEO
Search engines like Google use schema markup to better understand your content, which can lead to rich snippets, enhanced search results, and improved rankings.
AI System Optimization
Modern AI systems, including voice assistants and chatbots, rely on structured data to provide accurate responses and recommendations.
E-E-A-T Signals
Schema markup helps establish Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T) signals that search engines value.

Dynamic Schema Generation

Schema Markup for Law Firm Websites
Law firms have schema types built specifically for them. Used together, they describe the firm, its offices, its attorneys, and its content in a way search engines and AI systems can read directly.
LegalService for the Firm and Each Office
LegalService is a schema.org subtype of LocalBusiness meant for law firms and other legal providers. Add it to your homepage and to each office's location page, with details that match your Google Business Profile exactly.
{
"@context": "https://schema.org",
"@type": "LegalService",
"name": "Smith & Rivera Law",
"url": "https://example.com",
"telephone": "+1-407-555-0100",
"address": {
"@type": "PostalAddress",
"streetAddress": "100 Main Street, Suite 200",
"addressLocality": "Orlando",
"addressRegion": "FL",
"postalCode": "32801",
"addressCountry": "US"
},
"areaServed": "Orange County, Florida",
"knowsAbout": ["Personal Injury", "Car Accidents", "Wrongful Death"],
"openingHours": "Mo-Fr 08:30-17:30"
}
Attorney and Person Markup for Lawyers
Schema.org also includes an Attorney type, but schema.org itself notes that LegalService is more inclusive, so most firms use LegalService for the firm. For individual lawyers, use Person markup on each attorney bio page, with jobTitle, worksFor, and sameAs links to profiles such as your state bar listing or legal directory profiles. This strengthens the expertise signals that matter so much for legal content.
{
"@context": "https://schema.org",
"@type": "Person",
"name": "Maria Rivera",
"jobTitle": "Personal Injury Attorney",
"worksFor": {
"@type": "LegalService",
"name": "Smith & Rivera Law"
},
"url": "https://example.com/attorneys/maria-rivera"
}
Other Schema Types That Fit a Law Firm
- Article with an attorney author on blog posts, so each guide is tied to a named, credentialed lawyer
- FAQPage on practice-area pages that answer common client questions, written in line with your state's advertising rules
- BreadcrumbList to show how practice-area and case-type pages fit together
- Service for individual practice areas, such as DUI defense or estate planning, with the firm as the
provider
Only mark up what's actually visible on the page, and don't add review or rating markup for your own firm on your own site. Google doesn't show self-serving review stars for local businesses, and review content can also raise bar advertising questions. Validate everything with Google's Rich Results Test before publishing.
Schema works best as part of a well-built site. Our law firm website design and law firm SEO services include structured data from the start, and our generative engine optimization for law firms work builds on it to help firms appear in AI-generated answers. For the broader technical picture, see our guide to technical SEO and our article on how AI Overviews change legal search.
The Bottom Line
Implementing JSON-LD schema markup is no longer optional for websites serious about search visibility and AI optimization. By providing explicit signals about your content's meaning and context, you help both search engines and AI systems deliver better experiences to users.
Start with the schema types most relevant to your content, ensure accuracy and completeness, and monitor performance to refine your implementation. The investment in structured data markup will pay dividends in improved search visibility, enhanced user experience, and future-proofed content optimization.
Remember: the goal isn't just to implement schema markup, but to implement it thoughtfully in ways that genuinely help users and search systems understand your content better. If you'd like help adding schema to your firm's site, contact us.
