Perplexity indexing + live retrieval with citation backlinks; blocking is costly
Almost never block
PerplexityBot builds and refreshes the index behind Perplexity's AI answers. Blocking it is the most expensive mistake in AI SEO: you disappear from Perplexity citations while your training decision stays completely separate.
If you need to protect specific sections (pricing, docs), use path-scoped rules instead of a blanket Disallow: /.
