What is the Perplexity-User user agent?

Requests from Perplexity-User carry "perplexity-user" in the User-Agent header (matching is case-insensitive). The full string includes a version number that changes over time; Perplexity's documentation lists the current one. In robots.txt, the token is Perplexity-User.

How do I verify Perplexity-User?

Perplexity publishes the IP ranges Perplexity-User uses. A request is real when its IP is inside that list. Paste an IP into HadoSEO's free bot verifier to check it against the published data.

How do I block Perplexity-User in robots.txt?

Add "User-agent: Perplexity-User" followed by "Disallow: /" to your robots.txt. Blocking Perplexity-User does not block PerplexityBot: each has its own token and its own rule. robots.txt is a request, not a lock: a scraper using Perplexity-User's name ignores it, which is why verification matters.

Can I see when Perplexity-User visits my site?

Yes. HadoSEO logs every Perplexity-User request by page, checks it against Perplexity's published data, and flags requests that use the name from IPs Perplexity doesn't own. For a one-off look, the free log file analyzer reads a week of your server logs in the browser.

How to verify a real Perplexity-User request.

Perplexity publishes the IP ranges Perplexity-User uses. A request is real when its IP is inside that list.

01Check the User-Agent header contains "perplexity-user" (case-insensitive). That is only a claim: anyone can send it.
02Download Perplexity's published list (https://www.perplexity.ai/perplexity-user.json) and check the request IP falls inside one of its ranges.
03Inside the list: the real Perplexity-User. Outside it: a request using Perplexity-User's name from someone else's server.

Skip the lookups: the free bot verifier checks one IP against the same registry, and the log file analyzer checks every Perplexity-User request in a week of access logs. Requests that fail are flagged as spoofed, not hidden.

[ robots.txt ]

Block or allow Perplexity-User in robots.txt.

Add one of these groups to the robots.txt at your domain root. The token matches case-insensitively. Perplexity runs other crawlers with their own tokens, so a rule for Perplexity-User leaves PerplexityBot (search index) untouched.

block Perplexity-User

User-agent: Perplexity-User
Disallow: /

allow Perplexity-User

User-agent: Perplexity-User
Allow: /

robots.txt only binds crawlers that choose to follow it. A scraper sending Perplexity-User's user agent from its own servers won't, which is why HadoSEO checks the IP behind every request.
