Search results can make a product appear easy to document. A publishable catalog record needs much more: a current manufacturer source for material facts, an explicit review date, a clear German-market status and commercially usable imagery or a neutral placeholder.
Availability is a separate claim
A current manufacturer page can establish that a product exists, but not necessarily that it is marketed or delivered in Germany. Only an exact retailer or provider page can establish that provider’s current availability.
Missing links are safer than weak links
The catalog accepts products without a purchase button. Generic searches, mismatched bundles, stale pages and redirects are not substituted merely to create a commercial path.
Records age
Manufacturer claims require revalidation after 180 days and retailer links after 30 days. Automation creates a review report; it cannot publish a changed fact or retire a product.
The complete rules are available in the source methodology.
