To get cited by Perplexity, let PerplexityBot crawl your site in robots.txt, make sure your pages are indexable, and publish pages that answer a specific question directly near the top. Perplexity searches the web live and links numbered citations, so a crawlable, clear, relevant page can be cited.
How does Perplexity choose its sources?
Perplexity's help center says it searches the internet in real time and that each answer includes numbered citations linking to the original sources. That means citation depends on two things you can influence: whether Perplexity can reach your page, and whether the page answers the question better than alternatives. Perplexity does not publish a ranking formula, so anything beyond those two is guesswork.
Which Perplexity bots should you allow?
Perplexity documents two user agents in its bot guide:
- PerplexityBot is the crawler that surfaces and links sites in Perplexity search results. Perplexity says it is not used to crawl content for AI foundation models.
- Perplexity-User fetches a page when a person asks a question that needs it. Perplexity says this fetcher generally ignores robots.txt because a user requested the visit.
To appear in search results, Perplexity recommends allowing PerplexityBot in robots.txt and allowing its published IP ranges. Changes can take up to 24 hours to apply.
Step 1: Check that you are not blocking it
Open yourdomain.com/robots.txt and look for a Disallow rule that applies to PerplexityBot or to all agents. A security tool or CDN rule can also block bots that robots.txt allows, so test with a request to a page and check your firewall logs. The robots.txt side is covered step by step in how to allow ChatGPT and Perplexity in robots.txt.
Step 2: Make the page indexable and clean
A page that cannot be fetched or that sends mixed signals is less likely to be used. Check that it returns a normal 200 status, is not set to noindex and declares one preferred URL. If you are unsure, use the canonical URL guide and the indexing check.
Step 3: Answer the question first
Write the question as a heading or title, then answer it in the first one or two sentences before any background. A model building an answer can lift a self-contained passage; it cannot lift one that needs three paragraphs of setup. Keep one topic per page, define terms where they first appear and name specifics instead of vague claims.
Step 4: Add what other pages lack
If ten pages say the same thing, a citation has little reason to pick yours. Add a decision framework, a worked example, a correction to outdated advice or first-hand detail. This is also the lever you control best, and it helps ordinary search too. The same reasoning applies to Google's AI features, covered in how to appear in Google AI Overviews.
Step 5: Check whether it worked
- Ask Perplexity the exact question your page targets, and a few variations.
- Look at the numbered citations to see whether your domain appears.
- Check your server logs for PerplexityBot requests to confirm it can fetch the page.
- Repeat after a few weeks, since answers change.
Nightcrop's audit includes a check that AI crawlers can reach your site, and its reports track whether AI answer engines cite your domain.
What does not work
There is no file or tag that forces a citation. If you are wondering about the llms.txt file, see what it does and does not do. Repeating a keyword or stuffing a page with FAQs for their own sake does not replace a clear, useful answer.
