What PerplexityBot is used for

Search indexing, AI training, AI answers, or retrieval impact

Allowing PerplexityBot may keep direct retrieval open, but it does not guarantee a Perplexity visit or citation. Blocking it can reduce direct retrieval opportunities.

Blocking may reduce direct retrieval opportunities, while allowing does not guarantee a visit or citation.

How to allow PerplexityBot

Add an allow rule when this crawler should be permitted to request public pages. Test the deployed robots.txt file on the exact URL path, because a homepage allow can coexist with deeper disallow rules.

User-agent: PerplexityBot
Allow: /

User-agent: *
Allow: /

How to block PerplexityBot

Add a block rule only when the policy intent is to restrict this crawler. Blocking is a public directive for compliant crawlers, not authentication and not a ranking control.

User-agent: PerplexityBot
Disallow: /

User-agent: *
Allow: /

Common verification notes

  • Test PerplexityBot on guide, docs, pricing, and support paths.
  • Confirm that answer-ready pages are not blocked while the homepage is allowed.
  • Use server logs and Search Console trends as follow-up evidence.

How to interpret a robots.txt checker result

An allow result means the matched robots.txt directive does not block this compliant crawler on the tested path. It does not guarantee a visit, indexing, inclusion, ranking, or citation. A block is a public crawler directive, not authentication or access control.

Recommended action: Allow it when Perplexity discovery matches your policy and verify behavior against current official documentation.
