Perplexity SEO is optimizing your content to be cited among Perplexity's 4–6 sources per answer, the highest-value citation surface per visit in AI search. This hub collects GeoXylia's Perplexity cluster: the pipeline, the signals, the audit framework, and the tools.
How Perplexity selects sources
The best-documented pipeline of any AI engine [KB §2]: semantic relevance (custom embeddings, near-miss rejection) → freshness (70% of top citations within 12–18 months; 30-day content at 3.2x) → structural quality (90% of top-cited sources answer in the first 100 words) → topical authority (niche beats sitewide) → engagement → ML re-ranking (~0.7 threshold, discard-and-restart below it).
The translation: answer the exact query in the first 100 words, show real update dates, be the niche expert, corroborate claims across independent domains.
