Perplexity
Perplexity is an AI answer engine that responds to questions with synthesized answers and prominent inline citations, making it one of the most source-transparent engines to optimize for.
Perplexity is an answer engine built around citing its sources. It treats every query as a search, retrieves relevant pages, and writes an answer with numbered inline citations — making it unusually transparent about which sources it used, and therefore a clear target for AEO.
Visibility in Perplexity depends first on being crawlable by PerplexityBot, then on being the passage its retrieval step selects — the extractability pillar — and on the authority signals that decide which of several good sources gets cited. Because its citations are so visible, Perplexity is a useful engine for measuring whether your AEO work is landing.
Example. Ask Perplexity a question and the answer carries small numbered references; hovering or clicking reveals the exact pages used. Tracking how often your domain appears in those references, across your prompt set, is a direct read on your Perplexity visibility.
