Questions

What is Perplexity-User?

Fetches pages for Perplexity answers and the sources it cites, at a user's request. MetricRaven groups it under AI answers: assistants opening a page because a person asked about it.

How do I verify that a request really comes from Perplexity-User?

Check both the user agent and the IP. Requests from Perplexity-User contain "Perplexity-User" in the user agent and come from the IP ranges Perplexity publishes (https://www.perplexity.ai/perplexity-user.json). A request with the name but another IP is likely spoofed.

How do I block or allow Perplexity-User?

Add a robots.txt group for "Perplexity-User" with the paths to allow or disallow. Fetchers that act for a user may ignore robots.txt; block those at your server or firewall instead.

How can I see when Perplexity-User visits my website?

Most crawlers never run JavaScript, so browser analytics miss them. MetricRaven's @metricraven/ai-crawl package reports crawler requests from your server, verifies their IPs against published ranges, and shows which pages each crawler reads.
