We're a vertical SaaS in predictive maintenance with schema.org/HowTo markup on our top-ranking articles, and we've noticed Claude is citing our content in answers but linking to a cached or outdated version of the page—sometimes 6+ months old—instead of the current live URL. Our domain crawl logs show Claude visits 2–3x weekly. Is this a URL canonicalization parsing failure, or should we be adding schema.org/version + schema.org/dateModified signals to force re-attribution to the latest version?

Asked by Yuki T.
This is almost always a crawl-to-index lag, not a schema parsing issue. Claude's training data snapshot is older than its live crawl, so it's pulling answers from the newer crawl but attributing to whatever URL was in the training corpus. Add explicit schema.org/version markup + ensure dateModified is ISO 8601 on every update, but the real fix is submitting your updated URLs to Anthropic's crawl request form if one exists—otherwise, you're waiting for the next major model retrain.
