Also known as: Perplexity, Perplexity.ai
Perplexity AI is an AI search engine launched in 2022 that presents LLM answers with clearly linked sources at the head of every answer. Perplexity uses a multi-model approach (its own models plus, optionally, GPT-4, Claude and Llama) and runs its own crawler, PerplexityBot. It is particularly interesting for GEO: the citation rate can be measured transparently, since every answer lists its sources visibly, and Perplexity users click through to sources markedly more often than ChatGPT users do.
Perplexity's answer logic favours four things. Fresh sources with a clearly visible publication or update date. Structured content with a clear question-and-answer logic in the H2 headings. Factually substantiated statements — sources that cite sources themselves are preferred. And domain authority, although less so than ChatGPT: Perplexity is less brand-driven, which gives smaller specialist domains a realistic chance of being cited. A well-structured guide with genuine evidence can be cited even at a domain rating of 25.
Perplexity has two modes. Quick Search handles straightforward answers; Pro Search produces deeper multi-step answers with targeted follow-up research. Pro Search cites considerably more sources per answer, often six to twelve instead of two to four — so a page ranking between fourth and tenth for a commercial keyword has far better citation chances in Pro Search than in Quick Search.
Perplexity runs two crawlers: PerplexityBot for ordinary web indexing and Perplexity-User for on-demand requests during a user session. Both should be allowed in robots.txt. Blocking Perplexity makes a site impossible to cite in Perplexity answers; blocking the user crawler removes it from live requests in which someone explicitly asks about a particular domain.
Example: A niche outdoor-equipment blog with a domain rating of 28 rewrites twelve core guides around a clear question-and-answer structure and adds Schema.org markup with author and datePublished. After ten weeks its citation rate in Perplexity Quick Search is above 30 per cent for seven of the twelve main topics — and after four months the direct referral traffic from Perplexity exceeds that from Bing and matches what a Google ranking around position 15 delivers.
