Perplexity-User is Perplexity's user-action fetcher. It retrieves a specific page in real time in response to a user query, rather than crawling your whole site for indexing. Its activity reflects genuine user intent, not scheduled indexing.
Blocking Perplexity-User prevents these user-initiated fetches, so Perplexity can't pull your live page into an answer even when a user explicitly asks about it.
How to check and control it
To check, look in your robots.txt for a rule targeting this user-agent. To allow or block it:
User-agent: Perplexity-User
Disallow: / # blocks it — remove or set "Allow: /" to permit

FAQ
How is Perplexity-User different from PerplexityBot?
Perplexity-User fetches a page in real time when a user's query requires it, while PerplexityBot crawls and indexes your site in the background. Blocking Perplexity-User stops on-demand fetches; blocking PerplexityBot removes you from Perplexity's index and citations.
Should I block Perplexity-User?
Usually not, since it acts on real user requests and blocking it mainly limits your reach when users ask about your content. If you want full control over which Perplexity agents can access your site, SEO AEO Specialist diagnoses and helps you fix each rule, not just monitor it.
