Groundbreaking 2.2 Million Prompt Study Reveals How Law Firms Can Achieve 90% AI Visibility Scores Across ChatGPT, Claude, and Perplexity Using Proven Content Depth and Authority Strategies
Exclusive Analysis: How Goodie’s AEO Periodic Table Data Shows Attorneys Can Leverage Content Quality (90/100), Trust Signals (88.2/100), and Citation Networks (86.8/100) to Dominate AI Generated Legal Recommendations
This analysis is based on data from Goodie’s 2025 AEO Periodic Table, a comprehensive study of over 2.2 million prompts across leading AI models.
In the rapidly evolving landscape of AI driven search, law firms face a critical challenge: how to ensure their expertise surfaces when potential clients query ChatGPT, Claude, Perplexity, or other AI models for legal guidance. Goodie’s newly released AEO (Answer Engine Optimization) Periodic Table provides unprecedented insights into what drives visibility across six major AI platforms. The implications for legal professionals are profound.
The Fundamental Shift: From Page Rankings to Answer Assembly
The traditional SEO playbook that law firms have relied upon for decades is becoming obsolete. As Goodie’s analysis of 2.2 million English prompts reveals, AI models don’t rank pages. They assemble answers by fetching, verifying, and synthesizing information from multiple sources. For attorneys, this means your firm either becomes a trusted piece in the AI’s knowledge assembly, or you risk complete invisibility in AI generated legal guidance.
“LLMs don’t ‘rank pages,’ they assemble answers. Your job is to be the easiest, most credible piece to fetch, verify, and synthesize.”
— Goodie, AEO Periodic Table (2025)
Key Findings That Matter for Legal Practices
1. Content Depth Trumps Volume Score: 90.0/100
Goodie’s research shows that content quality and depth scores 90.0 across all models, making it the second most critical factor. For law firms, this validates a fundamental shift in content strategy:
“What stood out to me most about Goodie’s research is that AI isn’t just rewarding keyword density, it’s rewarding genuine expertise. The firms that dive deep, connect ideas, and make their knowledge easy for AI to understand will own the future of legal visibility.”
— Jeff Howell, Founder of Lex Wire Journal
- What Works: Comprehensive practice area pages that thoroughly explain legal processes, potential outcomes, and case examples
- What Doesn’t: Thin location pages or keyword stuffed blog posts
Lex Wire Implementation: Our AI Visibility programs focus on creating authoritative, deep content assets that establish your firm as the definitive source on specific legal topics. We’re not creating more content. We’re creating content that AI systems trust and cite.
2. The Credibility and Trust Factor Score: 88.2/100
Claude leads with the highest trustworthiness requirements (95/100), while even the most lenient model, Grok, still demands significant credibility (82/100). For attorneys, this presents both a challenge and an opportunity.
Legal Industry Advantages:
- Bar admissions and professional credentials provide inherent trust signals
- Case results and peer recognitions offer verifiable performance metrics
- Attorney client testimonials (where ethically permitted) provide authentic social proof
Lex Wire Approach: We leverage your existing credibility markers such as bar memberships, case victories, and professional awards, and structure them in ways AI models can verify and reference. Our Lex Wire Journal placements create authoritative citations that boost your trust signals across all platforms.
3. Citations and Mentions: The New Digital Referral Network Score: 86.8/100
Perplexity shows the highest dependency on citations (92/100), but all models heavily weight authoritative mentions. For law firms, this mirrors the traditional referral network but in digital form.
Strategic Implications:
- Guest articles in legal publications carry exponential value
- Mentions in news coverage of cases become permanent authority markers
- Professional directory listings serve as trust anchors rather than lead generators. Today, platforms like Avvo, Justia, and FindLaw aren’t as effective at directly driving case inquiries, but maintaining accurate and consistent listings still provides crucial citation signals that reinforce your firm’s digital authority across AI and search ecosystems. See Lex Wire feature on Legal Directory Decline.
4. The Rise of Co-Occurrence Score: 76.5/100
This new factor in reveals that AI models cross reference multiple sources to validate information. When your firm appears consistently across various authoritative sources with aligned messaging, visibility multiplies.
Practical Application for Law Firms:
- Consistent attorney bios across all platforms
- Unified practice area descriptions
- Standardized case result presentations
Model Specific Strategies for Legal Queries
| AI Model | Key Characteristics | Optimization Focus |
|---|---|---|
| ChatGPT | Most balanced approach. Favors comprehensive, practical legal information | Create detailed FAQ content addressing common legal questions with practical guidance |
| Claude | Highest trust requirements. Demands exceptional credibility and factual accuracy | Support all claims with case citations, statutory references, and verifiable outcomes |
| Perplexity | Citation dependent. Highest reliance on authoritative references (92/100) | Maintain current information, pursue Wikipedia notability, actively seek media mentions |
| Google AI Mode | Localization leader. Strongest geographic relevance (80/100) | Optimize Google Business Profiles, create city specific practice pages |
| Gemini | Content excellence focus. Highest content relevance (94/100) | Build semantically rich topic clusters with interlinked expertise |
| Grok | Real time focus. Values fresh content and social engagement | Maintain active social presence, update content frequently |
The Agent Experience (AX) Factor: Technical Excellence Matters
While AX scores decreased overall (from 94.8 to 74.2), they remain crucial for initial discoverability. For law firms, this means:
Critical Technical Requirements:
- Page Load Speed: Under 1.2 seconds (especially for Grok)
- Structured Data: FAQ and LegalService schema markup
- Mobile Performance: Full responsiveness and functionality
- Crawlability: Clean robots.txt and XML sitemaps

Measuring Success in the AI Era
Traditional SEO metrics no longer tell the full story. Based on Goodie’s research, law firms should track:
New KPIs for AI Visibility:
- Citations per 100 Prompts (CP100): How often your firm appears in AI responses
- Share of Answer: Percentage of relevant queries where you’re cited
- Cross Model Visibility: Presence across different AI platforms
- Co-Occurrence Coverage: Consistency of mentions across sources
The Bottom Line: Adapt or Disappear
Goodie’s AEO Periodic Table confirms what forward thinking law firms already suspect: the rules of digital visibility have fundamentally changed. AI models are becoming the primary interface between potential clients and legal information. Firms that adapt their digital presence for AI consumption will capture tomorrow’s clients. Those that don’t risk invisibility in an AI first world.
The data is clear: success in AI search requires more than traditional SEO. It demands deep expertise demonstration, verifiable credibility, consistent authority signals, and technical excellence. For law firms ready to lead rather than follow, the opportunity is unprecedented.

What is AEO (Answer Engine Optimization) and why does it matter for law firms?
Answer Engine Optimization (AEO) is the practice of optimizing content to appear in AI generated responses from platforms like ChatGPT, Claude, and Perplexity. For law firms, AEO matters because potential clients increasingly use AI assistants to find legal advice and attorney recommendations. According to Goodie’s 2025 AEO Periodic Table, content depth (90/100) and credibility (88.2/100) are the most critical factors for AI visibility.
How do AI models like ChatGPT and Claude select which law firms to recommend?
AI models select law firms based on multiple visibility factors. The top factors according to Goodie’s research are: content relevance (93/100), content quality and depth (90/100), credibility and trust (88.2/100), and citations from authoritative sources (86.8/100). Models verify information across multiple sources, prioritizing firms with consistent messaging, verifiable credentials, and comprehensive practice area content.
What technical requirements must law firm websites meet for AI visibility?
Law firm websites need: page load speeds under 1.2 seconds, LegalService and Attorney schema markup, clean robots.txt files, comprehensive XML sitemaps, mobile responsive design, and structured FAQ content. The Agent Experience (AX) factor scores 74.2/100 in importance, with Perplexity showing the highest dependency on structured data at 80/100.
Which AI platforms are most important for law firms to optimize for?
Law firms should prioritize optimization for ChatGPT (most balanced approach), Claude (highest trust requirements at 95/100), Perplexity (citation dependent at 92/100), and Google AI Mode (localization leader at 80/100). Each platform has different optimization requirements, with ChatGPT favoring comprehensive content, Claude demanding verifiable facts, and Perplexity requiring strong citation networks.
How can small law firms compete with larger firms in AI search results?
Small law firms can compete by focusing on content depth over volume, building local authority through Google Business Profile optimization (68.3/100 importance), creating comprehensive practice area guides, securing citations from legal publications, and maintaining consistent messaging across all platforms. The co-occurrence factor (76.5/100) rewards firms that appear consistently across multiple authoritative sources, regardless of firm size.
What content strategies work best for AI visibility in the legal industry?
The most effective content strategies include: creating comprehensive practice area pages with detailed legal process explanations, developing deep dive guides on specific legal topics, maintaining fresh content with regular updates (81.2/100 importance), building topical authority clusters with interlinked content, and incorporating verifiable case results and metrics (67/100 importance). Focus on depth and expertise rather than keyword density.
How long does it take to see results from AI optimization efforts?
AI optimization results typically follow this timeline: Immediate improvements (1 week) from technical fixes and schema implementation, short term gains (30 days) from content updates and citation building, and significant visibility increases (90 days) from comprehensive authority building and co-occurrence optimization. Models like Perplexity value content freshness highly (87/100), so recent updates can surface quickly.
What are the key differences between traditional SEO and AEO for law firms?
Unlike traditional SEO which focuses on ranking pages, AEO focuses on becoming a trusted source that AI models fetch and synthesize. Key differences include: AEO prioritizes content depth over keyword optimization, requires consistent messaging across multiple platforms (co-occurrence factor), values verifiable credentials and metrics more highly, depends less on traditional SERP rankings (61.8/100), and requires structured data for AI comprehension rather than just search engine indexing.
