Perplexity answers questions with numbered links to the pages it used. This guide sets out what Perplexity says about how it finds and cites pages, what it leaves unsaid, and the steps that make your pages easy to use.

The short answer

How does Perplexity pick its sources?

Perplexity says it searches the web in real time and cites sources it describes as authoritative, but it does not publish how sources are ranked. Its documented crawler, PerplexityBot, surfaces and links sites. To be eligible, allow that crawler and publish clear, accurate, attributed pages.

Key takeaways
  • Perplexity documents two bots: PerplexityBot, which surfaces and links sites, and Perplexity-User, which acts on user requests.
  • Perplexity says PerplexityBot is not used to crawl content for AI foundation models.
  • Perplexity recommends allowing PerplexityBot in robots.txt, and permitting its published IP ranges.
  • How Perplexity ranks or chooses sources is not published, so any formula is a guess.
  • Clear answers, named authors, dated sources and fast pages help here and in every other engine.

Perplexity's two bots

Perplexity is an answer engine: you ask a question, it searches the web, writes a summary and lists numbered sources. Being one of those sources can send visitors, and it can also put your name in front of readers who never click.

Perplexity publishes two things we can rely on: how its bots behave, and a general description of how answers work. Everything about ranking is outside what it has said.

How does Perplexity find pages?

Perplexity's help page says it searches the internet in real time, gathers information from authoritative sources such as articles, websites and journals, and gives each answer numbered citations that link to the original sources. It does not explain how sources are ranked or selected, and it does not say how a publisher gets included.

Its bots guide describes two bots. PerplexityBot is designed to surface and link websites in Perplexity search results. Perplexity-User supports user actions: when a person asks a question, it may visit a page to help answer and may link to that page in the response.

What does Perplexity say about training and robots.txt?

Perplexity says PerplexityBot is not used to crawl content for AI foundation models, and that Perplexity-User is not used to collect content for training. It recommends allowing PerplexityBot in your robots.txt file so your site can appear in search results, and permitting requests from its published IP ranges. Perplexity-User is different: because a user triggers the visit, Perplexity says it generally ignores robots.txt rules. Changes to these settings may take up to 24 hours to apply. Both pages were read on 12 November 2026, and neither states a date.

What is not published?

How Perplexity ranks pages, which signals it weighs, how it decides between two pages that answer the same question, and how often a given site is cited. We found no Perplexity statement on these. Guides that list 'Perplexity ranking factors' are working from observation or guesswork. Observation can still be useful, as long as it is labeled and rechecked, because Perplexity can change how it works at any time.

How do you make your pages easy for Perplexity to use?

The steps follow from what Perplexity documents and from ordinary good practice.

  • Allow PerplexityBot. Check robots.txt, your CDN and any firewall or bot-protection rules, which sometimes block unfamiliar crawlers without you noticing.
  • Answer first. Put a direct answer to the page's question in the first two sentences, so a summary can use it and a reader can verify it.
  • Be a source worth citing. Give original information, name the author and why they know the subject, cite your own sources with dates, and keep facts current.
  • Keep pages plain and fast. Put the content in text, make the page quick on a phone, and give each page one clear topic.
  • Keep details consistent. Business name, prices, hours and service areas should match across your site and your profiles.

Is Perplexity different from Google here?

In outline, no. Google says its AI features follow the same SEO best practices and need no special markup or files, and the steps above also help there. The differences are practical: a different crawler to allow, a different set of citations to check, and a different, smaller audience. We have no verified figures for Perplexity's share of searches, so we give none.

How do you check if Perplexity cites you?

Ask Perplexity the questions your buyers ask, the same way each month, and record whether your page appears among the numbered sources. Check your server logs or your bot-protection reports for PerplexityBot visits to confirm it can reach you. Count visits from perplexity.ai in analytics as a partial floor. Our guide to tracking AI search visibility gives the method and its limits.

What should you avoid?

Avoid anyone who promises citations in Perplexity, who sells a secret formula for its ranking, or who recommends publishing many thin pages to cover every question. Avoid blocking the crawler by mistake and then wondering why you are absent. And avoid treating one engine as the whole picture: work that helps Perplexity usually helps every other search too.

Conclusion

Perplexity tells us how its bots behave and that it cites sources, and says nothing about how it ranks them. Allow the documented crawler, make clear and attributed pages, and measure what reaches the business.

Common questions

  • Allow PerplexityBot, publish clear pages that answer the question first, name the author, cite dated sources and keep facts current. Perplexity does not publish how it ranks sources, so no one can promise a citation. Check whether you appear by asking your buyers' questions.

  • If you want your site to appear in Perplexity search results, yes. Perplexity recommends allowing PerplexityBot and permitting its published IP ranges, and says PerplexityBot is not used to crawl content for AI foundation models. Check CDN and firewall rules too.

  • PerplexityBot surfaces and links websites in Perplexity search results. Perplexity-User supports user actions: when someone asks a question it may visit a page to help answer and link to it. Perplexity says Perplexity-User generally ignores robots.txt because a user triggered the visit.

  • Perplexity's bots guide says PerplexityBot is not used to crawl content for AI foundation models, and that Perplexity-User is not used to collect content for training (read 12 November 2026). Check the guide again for changes, since it shows no date.

  • The basics are the same: helpful, accurate, attributed pages that crawlers can reach. The differences are practical, such as allowing a different crawler and checking a different set of citations. Google says its AI features follow the same SEO best practices.

  • Look for visits from perplexity.ai in your analytics, and for PerplexityBot in your server logs. The count is partial, because some visits arrive without a referrer, so also ask new customers how they found you and sample answers to your buyers' questions.
