Header versions can change. Use the product token for robots.txt matching and consult the Perplexity crawler documentation before changing enforcement. Reference checked on 18 October 2026.

How do I allow PerplexityBot?

Merge this group into the robots.txt served from the page's origin. Keep any path exclusions that still apply. A named group may stop inheriting the wildcard group's exclusions.

Copy code

User-agent: PerplexityBot
Allow: /

Allow retrieval and block training

This example separates the operator's documented identities where possible. It changes crawl or data-use preferences; it does not grant server access. User-triggered agents may follow a different robots.txt policy.

Copy code

User-agent: PerplexityBot
Allow: /

User-agent: Perplexity-User
Allow: /

Use the interactive robots.txt builder for a per-bot policy. Test the final file against the exact page path before deploying it.

What if the CDN returns HTTP 403?

A robots.txt allow rule cannot override an HTTP 403, a login gate or a JavaScript challenge. Compare the returned body with the public page and locate the request in CDN security events. Grant an exception only after verifying the sender, scoped to the affected public routes.

The scanner uses its own network. A successful header probe does not verify Perplexity access, and a refused probe does not establish a vendor-wide block. See the WAF troubleshooting guide.
