Definition

Full definition
Perplexity combines retrieval and generation: it searches or browses sources, then produces a concise answer with inline citations. Users often treat it as a research tool for product comparisons, definitions, and current-events style questions.
Because citations are central to the product UX, brands and publishers care about being selected as a source—not only being mentioned in prose. Crawl access for Perplexity’s bots, clear extractable content, and authoritative pages improve the chance of appearing in those citations.
GEO and AEO tactics—entity clarity, answer-first sections, and trustworthy third-party coverage—map closely to how citation-oriented answer engines behave. See Answer Engine, Citation, and AI Referral Traffic.
Example
A documentation site sees referral sessions from perplexity.ai after its API reference is cited in answers about integrating a payment SDK.
