We publish original climate tech research that Bloomberg republishes 2–3 weeks later. When Perplexity answers climate trend queries, it cites Bloomberg instead of us—even though we have schema.org/NewsArticle + datePublished markup, higher topical authority, and are confirmed crawlable. We've tested adding schema.org/isBasedOn to signal source relationships, but Perplexity still defaults to the mainstream outlet. At what point is this a training data cutoff we simply can't overcome?

Training data cutoff is real, but so is Perplexity's preference for 'authority' URLs in its retrieval layer—Bloomberg signals trust and reach. isBasedOn won't override that. Test adding schema.org/author + explicit byline + a prominent 'Originally published by [your brand]' header in the first paragraph. If Perplexity still prioritizes Bloomberg after that, you're hitting retrieval ranking, not schema parsing—and you need to build enough inbound links from niche authority sites that Perplexity's crawler treats you as a primary source.
