How to get cited by Perplexity
Perplexity is the most citation-aggressive of the four major AI search engines: every answer paragraph carries explicit source footnotes. This guide is the engineering protocol for getting a specialty business into those footnotes consistently.
Perplexity differs from ChatGPT in one operationally important way: every answer paragraph carries explicit source footnotes linking back to the cited sites. This makes Perplexity the most transparent of the four major AI search engines for measuring citation. If your business is cited, you can see it. If your competitor is cited and you are not, you can see exactly which of their pages was quoted and why.
The engineering work to get cited by Perplexity is similar to ChatGPT but with two specific differences: freshness weighting is higher, and Reddit corroboration is weighted disproportionately.
1. Allow PerplexityBot explicitly
Add these lines to robots.txt:
User-agent: PerplexityBot
Allow: /
User-agent: Perplexity-User
Allow: /PerplexityBot is the standard crawler used to maintain the retrieval index. Perplexity-User is the user-agent used when a Perplexity user actively asks a question and the system fetches a candidate source. Both should be allowed.
2. Ship server rendered HTML with extractable content
Same as ChatGPT and every other AI crawler. If the initial HTML response is a JavaScript shell, Perplexity indexes nothing. Test with curl -A PerplexityBot https://your-site.com and verify your services, pricing, and providers are readable.
3. Keep content fresh
Perplexity penalizes content older than six months more than other engines. Maintain quarterly updates to treatment pages, provider bios, pricing, and FAQs. Each update should bump the sitemap lastmod and schema dateModified fields. Stale content with old dates loses to newer competitor content even if the older content is technically more authoritative.
4. Seed authentic Reddit threads
Reddit is overweighted in Perplexity retrieval. Identify subreddits where your prospects ask questions (r/SemaglutideFreeSpeech, r/loseit, r/personalinjury, r/HomeImprovement). Provide substantive answers that name your business in context. Do not spam; one substantive thread is worth ten promotional comments.
5. Monitor citation state via Sonar API
The Perplexity Sonar API ($5 per million tokens as of 2026) lets you programmatically check whether your business is cited on a query set. KailxLabs uses Sonar as the primary engine in the citation tracking dashboard delivered with every build.
6. Submit your sitemap
Perplexity does not have a public sitemap submission interface, but submitting to Bing Webmaster Tools (via the Bing index that Perplexity falls back on) accomplishes the same goal. IndexNow auto-ping on every deploy is included in KailxLabs builds.
The complete engagement
All six requirements above are part of the KailxLabs AI Citation Foundation Build. The 45 day citation guarantee includes Perplexity as one of the four required engines. First Perplexity citations after launch typically appear day 14 to 21.
