We're a niche vertical publisher in supply chain tech with original deep-dive research that typically gets republished by mainstream outlets 3–4 weeks later. When Perplexity answers 'latest supply chain trends,' it pulls summaries from those republished articles but never attributes back to us directly—even though we're crawlable and have schema.org/Report + schema.org/NewsArticle + datePublished markup. Are we hitting a training data cutoff, or should we be adding schema.org/isBasedOn relationships to signal original research source?

Asked by Emma R.
Training data cutoff is the primary blocker—Perplexity's training set likely predates your domain's authority in this space. Schema.org/isBasedOn won't override that. Your move: build citations on Wikipedia's supply chain tech pages and industry association resources (not your own sites), then wait for Perplexity's next training cycle. Alternatively, pitch your research directly to Perplexity's editor network if one exists for your vertical.
