Attorney SEO for ChatGPT and Perplexity
By Mohammad Kashif, Chief Technology OfficerLast updated
Both read the live web and show their sources, so both reward pages that answer directly and can be verified. Perplexity weights recency and inline citation more heavily; ChatGPT weights how completely a passage answers the question. One body of work serves both.
Perplexity shows its citations on screen, which makes it the cheapest place to audit yourself. Run five client questions through it and you see immediately which domains own your market, without needing any tooling.
What the two have in common
Enough that treating them as one project is correct, even though the outputs differ.
- Both search the live web at query time rather than answering only from training data.
- Both display sources, which means being quotable is worth real referral traffic rather than just presence in an answer.
- Both favour pages whose claims can be corroborated elsewhere, which puts bar profiles, directories and press coverage on the critical path.
- Both read the raw HTML. Content that appears only after JavaScript runs is often invisible to them.
Where Perplexity differs
Perplexity behaves more like a research tool than a chat assistant, and its selection reflects that.
- Recency carries unusual weight. A page updated this quarter regularly outranks an older, more thorough one.
- It cites more sources per answer than ChatGPT typically does, which means the bar for inclusion is lower and a mid-authority firm page has a realistic chance.
- Its follow-up questions surface the adjacent queries clients actually ask next, which is a free content-planning input.
- PerplexityBot is a distinct user agent. Allow it explicitly rather than assuming a general crawler rule covers it.
Where ChatGPT differs
ChatGPT composes a fuller answer and cites more sparingly, so the selection bar per source is higher.
- It favours passages that answer the whole question rather than part of it. A page covering one narrow sub-point is less likely to be the quoted source.
- It runs its own query formulation, so the phrasing you rank for and the phrasing it searches may differ.
- It draws on training data as well as live search, which is why long-established firms sometimes surface without a current page supporting it.
- GPTBot, OAI-SearchBot and ChatGPT-User are three separate agents with different purposes. Allow all three.
What to actually do about it
The practical programme is short, because the overlap is large. Write the pages that answer your clients' real questions, lead every one with a direct answer, keep the firm's details identical across every profile a machine can read, refresh pages on a schedule so recency works for you rather than against you, and earn references from the sources these systems already quote in your market.
The differences above change emphasis, not direction. No firm needs a separate ChatGPT strategy and a separate Perplexity strategy; it needs one body of work and separate measurement.
Same work, different emphasis
| ChatGPT | Perplexity | |
|---|---|---|
| Sources cited per answer | Few | Many |
| Realistic bar for a mid-authority firm | Higher | Lower |
| Recency weighting | Moderate | High |
| Referral traffic potential | Low, often no click | Higher, citations are prominent |
| Crawlers to allow | GPTBot, OAI-SearchBot, ChatGPT-User | PerplexityBot |
| Easiest way to self-audit | Ask logged out, repeat | Read the citations on screen |
Common questions
- Is there a separate SEO strategy for ChatGPT and Perplexity?
- No, and firms that buy two are usually buying the same work twice. Both reward direct answers, verifiable claims, consistent entity data and authority. What differs is emphasis, Perplexity leaning harder on recency and ChatGPT on answer completeness. Run one programme and measure the two separately.
- Does Perplexity send real traffic to law firm websites?
- More than ChatGPT does, because it displays citations prominently and users click through to verify. The volumes are small compared with Google, but the visitors arrive having already read an answer that named you, which tends to make them better qualified than average organic traffic.
- How do I check whether Perplexity cites my firm?
- Ask it five questions a client would ask, in a logged-out window, and read the citation list on each answer. It takes a few minutes and requires no tooling. Record which domains appear instead of you, because that list is both your competitive picture and your outreach target list.
- Do I need to do anything different for Claude or Gemini?
- Not structurally. Claude reads the live web through its own crawler and rewards the same qualities; Gemini leans on Google's index and on Google's own business data, which raises the weight of an accurate Business Profile. Allow the crawlers, keep the details consistent, and the work carries across.
