Perplexity is an AI answer engine that searches the web for every question and shows numbered citations next to its answer. To be cited, your pages must be reachable by PerplexityBot, rank well in the web results Perplexity retrieves, and contain a clear, specific passage that answers the question.
How Perplexity finds sources
For each question, Perplexity runs one or more web searches, reads the most relevant pages and writes an answer that cites them with numbered references. Two user agents matter:
- PerplexityBot indexes websites so they can be surfaced and linked in answers. Perplexity states it is not used to train foundation models.
- Perplexity-User fetches a page when a user asks a question that needs it.
If either is blocked in robots.txt, or by a firewall that challenges bots, your pages are much less likely to be cited. Test both with the AI crawler checker.
What gets a page cited
- Retrieval: the page must appear in the search results Perplexity reads for that question. Classic SEO strength still matters.
- A direct answer: passages that answer the question in one or two sentences are quoted most.
- Specifics: prices, dates, statistics, step counts and named products give the answer something concrete to cite.
- Freshness: for time-sensitive questions, recently updated pages with visible dates are preferred.
- Credibility: well-known publications, official documentation, review sites and community discussions are cited often. Being mentioned on them helps you indirectly.
Step-by-step Perplexity optimization
1. Allow the bots
Add explicit Allow rules for PerplexityBot and Perplexity-User, and make sure your CDN or firewall does not block them with challenges.
2. Answer one question per section
Use question headings and a 40 to 60 word answer directly underneath. Perplexity often quotes exactly that sentence.
3. Put the facts in text
Prices, specifications and comparisons should be in HTML text and tables, not only in images or PDFs.
4. Keep pages current
Show an updated date, refresh numbers regularly and add the year to time-sensitive headings where it helps the reader.
5. Be present where Perplexity looks
Run the AI visibility checker to see which domains win citations for your category, then earn listings, reviews or expert contributions on those sites.
Measuring Perplexity traffic

Frequently asked questions
Does Perplexity use Google results?
Perplexity runs its own web retrieval and maintains its own index built by PerplexityBot. Pages that rank well generally are also more likely to be retrieved.
Should I block PerplexityBot?
Only if you do not want to appear in Perplexity answers. Blocking it makes citations much less likely.
