Term
Perplexity (search engine)
Perplexity is an AI-based answer engine that synthesizes web search results with a language model and delivers answers with inline source citations — an alternative to Google, focused on conversational research.
Perplexity — explained in more detail
Perplexity (founded 2022) combines its own web search pipeline with large language models (internal plus selectable GPT, Claude, Gemini). Unlike ChatGPT, Perplexity is web-grounded by default — every answer includes numbered inline citations to the sources used. For SEO practice, the relevant outcome is visibility as a cited source: appearing as a footnote in Perplexity answers brings qualified traffic outside classic SERPs.
A dedicated discipline has formed around it: GEO (Generative Engine Optimization) — structured content, clear definitions, and quality backlinks remain relevant, plus technical factors like accessible content (no hard paywall, clean markup, robots.txt allowing PerplexityBot).
Example / In practice
A specialist blog on AI pricing publishes a tabular comparison of token prices for major models and tags sources with clean dates and anchors. Within weeks the post gets cited in Perplexity answers when users ask “GPT vs Claude pricing” or similar — citation clicks generate measurable traffic, even though the Google position isn’t top 3.
Distinction from similar terms
ChatGPT Search and Google AI Overviews follow a similar principle (answer synthesis with sources) but differ in crawler, source selection, and delivery. Classic search engines return a list; Perplexity returns an answer. SearchGPT is OpenAI’s competing product, also retrieval-augmented.
