Definition

PerplexityBot is the web crawler operated by Perplexity AI, identified by the user-agent 'PerplexityBot'. It indexes web pages so Perplexity's answer engine can surface and cite them in real-time responses. Site owners manage its access through robots.txt directives.

Perplexity positions itself as an answer engine that cites its sources inline, so PerplexityBot's crawling directly feeds which pages can appear as references beneath its answers. Allowing the bot keeps your content eligible to be quoted and linked when users ask related questions.

Perplexity also uses a separate agent for fetching pages on demand when a user's live query requires fresh retrieval. Because citation placement drives referral traffic, Acromatico treats PerplexityBot access and content extractability as levers for earning visible, linked mentions in Perplexity's source lists.

Questions people ask

Does allowing PerplexityBot help my visibility?

Yes. Perplexity cites sources directly in its answers, so letting PerplexityBot crawl your pages keeps them eligible to appear as linked references. Blocking it removes your content from Perplexity's citation pool, cutting both visibility and the referral traffic those source links generate.

How is PerplexityBot different from GPTBot?

PerplexityBot serves Perplexity's citation-focused answer engine, indexing pages so they can be referenced in responses. GPTBot belongs to OpenAI and primarily collects content for model training. They are separate crawlers with distinct user-agents, controlled independently in your robots.txt.
