What is PerplexityBot?
PerplexityBot indexes web content to power Perplexity AI's search engine. Unlike Perplexity-User, this bot crawls proactively to build a search index rather than fetching on-demand for a specific user query.
What PerplexityBot means for your site
PerplexityBot proactively indexes your site for an AI-powered search engine, operated by Perplexity AI. Unlike AI assistants that fetch on-demand, this bot discovers and catalogs your content so it can surface in AI search results. Being indexed means your content is eligible to appear when users search through AI platforms. Not being indexed means you are invisible in this channel.
What should you do?
- Allow PerplexityBot to crawl your site
- Ensure your most important pages are accessible and well-structured
- Monitor which pages are being indexed through crawl activity
- Review robots.txt to ensure you are not accidentally blocking PerplexityBot

BotSights tracks every PerplexityBot visit in real time, including which pages it crawls, how often, and from where.
How to identify PerplexityBot
PerplexityBot uses the user-agent "perplexitybot" and respects robots.txt. It crawls systematically, similar to traditional search engine bots.
perplexitybotPerplexityBotHow to block PerplexityBot
Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known PerplexityBot user-agent pattern so the rules apply regardless of which one the bot announces.
Edit robots.txt with care
A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just PerplexityBot, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to PerplexityBot's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.
Option 1: Block all access
Tells PerplexityBot not to crawl any URL on your site. Use this when you want the bot completely off your content.
User-agent: perplexitybot
User-agent: PerplexityBot
Disallow: /Option 2: Block specific paths only
Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.
User-agent: perplexitybot
User-agent: PerplexityBot
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/Option 3: Slow down with a crawl delay
Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when PerplexityBot is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

Crawl-delay: 10Frequently Asked Questions
What is the User-Agent for PerplexityBot?
PerplexityBot identifies itself with the User-Agent string "perplexitybot" (alternate forms: PerplexityBot). Use this in robots.txt rules or server-side filters to control its access.
Should I block PerplexityBot?
Blocking PerplexityBot removes your content from Perplexity AI's AI search index. If you want visibility in AI-powered search results, allow it. The trade-off is similar to deciding whether to allow Bingbot or Googlebot.
Will blocking PerplexityBot affect my regular search rankings?
No. PerplexityBot indexes for AI-powered search, separate from traditional search engine rankings. Blocking it does not affect Googlebot, Bingbot, or your organic SEO position.
How do I verify a request is really from PerplexityBot?
User-Agent strings can be spoofed. Verify by checking the request's source IP. Check the operator's documentation for published IP ranges or reverse-DNS verification. BotSights does this automatically per visit.
Does PerplexityBot respect llms.txt?
llms.txt is an emerging proposal for AI-specific crawl guidance. PerplexityBot currently respects robots.txt, which is the reliable control mechanism. llms.txt support is operator-dependent and still evolving.
Is PerplexityBot different from Googlebot?
Yes. Googlebot indexes for traditional Google Search. PerplexityBot indexes for AI-powered search, which presents results as conversational answers with citations rather than blue link lists.
Will PerplexityBot affect my site speed?
Like any crawler, PerplexityBot consumes server resources. If crawl rate is excessive, set a Crawl-delay directive in robots.txt for this user-agent. Most AI search crawlers respect Crawl-delay.
