Perplexity AI

Perplexity AI is a conversational answer engine that synthesizes answers from live web sources and attaches inline citations to every claim. It is one of the most important AI search surfaces in 2026, especially for B2B, technical, and research-oriented queries.

Unlike a traditional search engine, Perplexity does not return a list of links. It returns a written answer with sources numbered in line. The user can click any citation, ask a follow-up, or switch into “Pro Search” mode for deeper research.

Why it matters for SEO

• Perplexity is heavily used by knowledge workers and developers—your highest-value audience
• It surfaces sources from the open web, including blog posts, docs, and research
• Citations are the unit of visibility. Being in the answer is the win; being clicked is a bonus
• Its crawler (PerplexityBot) is separate from OpenAI’s and Google’s, and worth its own robots.txt treatment

How to optimize for Perplexity

• Write pages that answer specific technical questions completely
