Ranking in Perplexity

How Perplexity retrieves and cites sources

It heavily favours content published or updated in the last 30 days and rewards pages with direct, extractable answers in the first paragraph. Unlike ChatGPT, Perplexity is more transparent about its citation sources and shows them prominently.
