How does AI search differ by practice area (PI, family, criminal)?
Personal injury queries trigger heavy disclaimers and directory-first answers because the engines are wary of liability. Family law queries surface mediation and legal aid before naming firms. Criminal defense queries lean on directories and bar association referrals because of urgency. The same AI engine behaves like a different product depending on the practice area, and your visibility strategy has to match.
Why practice area changes everything
ChatGPT, Perplexity, Gemini, Claude, and DeepSeek all run safety filters on legal advice. Those filters fire harder on some queries than others. A user asking "best estate planning attorney in Denver" gets a clean list of named firms. A user asking "who should I sue after a car accident" gets disclaimers, an instruction to call 911 if injured, and only then a list of personal injury directories. Same engine, same city, very different output.
We ran four prompts on the same day across all five engines, varying only the practice area. The patterns below held across every engine, with intensity differences but the same shape.
Personal injury: high commercial intent, heavy disclaimer wall
PI is the most-advertised category on Google by spend per click, and the AI engines know it. Queries like "car accident lawyer near me" return:
- A 2-3 sentence disclaimer about needing a licensed attorney for your jurisdiction.
- A push toward state bar referral services and Avvo's lawyer search before naming any specific firm.
- When firms are named, they are usually high-review-count Avvo profiles or Super Lawyers entries, not paid Google ads.
The implication for PI firms: AI search is not going to replace your Google Ads spend in 2026. Engines deliberately suppress aggressive commercial answers in PI. The win is being in the directory pool the engines pull from. Avvo profile depth, Super Lawyers selection, real case results pages, and substantive Google reviews matter more than blog content for PI specifically.
Family law: sensitive, mediation-first
Ask Perplexity "how do I file for divorce in Texas" and the answer leads with: consider mediation, contact the Texas Lawyer Referral Service, look at legal aid if income-qualifying. Firm names appear in a third or fourth paragraph, often as "some Texas family law firms include...".
Two things drive this. First, family law queries are often emotionally loaded and the engines are tuned to reduce harm. Second, the courts and bar associations explicitly promote mediation in many states, so the authoritative sources the engines lift from are pro-mediation.
What this means for family law firms:
- Content that competes with this framing wins. A page titled "Mediation vs litigation: which fits your case" outranks a page titled "Top divorce attorney in Houston" in AI answers.
- Bar association membership and certified family law specialist designation come up disproportionately in cited content.
- Local schema and Avvo profile depth still matter, but they are necessary not sufficient.
Criminal defense: urgency-driven, directory-heavy
Criminal queries are different. "DUI lawyer in Phoenix Saturday night" or "criminal defense attorney 24 hours" get short, action-oriented answers. The engines correctly read these as time-sensitive. Output looks like:
- Top of the answer: call the public defender, call the state bar referral hotline.
- Middle: 3-5 firms with 24/7 phone numbers prominently visible.
- Bottom: brief notes on what to say and not say after arrest.
Firms that show up consistently in criminal queries share three traits we have observed across roughly 25 firm scans: 24/7 phone listed in schema and on Google Business Profile, Avvo profile shows criminal defense as primary practice area not just secondary, and at least one substantive case result published on the firm site.
Estate planning: low-intensity, content-driven
One more for contrast. Estate planning queries ("do I need a will", "trust vs will") behave like B2B SaaS queries. Long answers, comparison content cited heavily, named firms only when the user explicitly asks for one. We have seen Nolo, FindLaw articles, and bar association explainers dominate the citation lists. Firms that publish substantive comparison content ("revocable vs irrevocable trust", "avoiding probate in [state]") get cited; firms with thin practice-area pages do not.
What to do with this
Three takeaways:
- Audit your AI visibility per practice area, not as a single firm number. A PI firm with strong family law side practice will show wildly different visibility scores in each.
- Match your content strategy to the engine behavior in your area. PI firms invest in directory hygiene and case results. Family law firms invest in mediation-aware content. Estate planning firms invest in long-form comparison guides.
- Track all five engines. ChatGPT and Gemini disclaim more on PI; Perplexity disclaims less but cites directories more; Claude is conservative across all areas; DeepSeek is the noisiest. The mix matters.
