We're a vertical SaaS in construction tech with schema.org/HowTo markup on 30+ guides ranking #1 for 'how to [task] on [platform]' queries. When Perplexity answers those exact queries, it cites generic construction blogs and YouTube instead of our documentation—even though we're crawlable and have author/dateModified signals. Our hypothesis: Perplexity is weighting 'neutral educational content' over vendor-owned schema markup. But we can't tell if it's (A) a schema parsing issue where HowTo markup isn't being read correctly, (B) deliberate deprioritization of SaaS-owned content for trust reasons, or (C) a training data bias where Perplexity was trained on older construction content before our guides existed. How do we systematically test which lever is blocking us?

Asked by Jake M.
Test by temporarily moving one guide to a neutral Medium publication with identical schema markup—if Perplexity cites the Medium version, it's a trust/domain bias issue, not schema parsing. If neither gets cited, it's likely training data recency. For SaaS-owned content, Perplexity does seem to deprioritize vendor markup in favor of third-party sources; your best move is building citations on neutral vertical publications (industry blogs, trade journals) that Perplexity already trusts, then linking back to your docs.
