How CASLINK updates links
We separate the destination change date from a separate manual check marker. This prevents a directory listing from being presented as a guarantee that a destination is reachable for every user.
Update date
The “Updated” date shows when the directory record changed. Replacing a destination URL updates that timestamp. It does not mean the destination is reachable for every user; availability can depend on country, ISP and the operator itself.
Manual check marker
An administrator can separately mark a listing as checked. If that marker exists, the brand page shows its date. Otherwise CASLINK explicitly says that no separate manual check is recorded.
Stable pages and redirects
Each indexable brand page keeps a stable SEO URL, while access buttons use a technical /link/ redirect. Technical redirects are excluded from indexing, and old aliases can be preserved after path changes so previously published links continue to work.
Change history
When a destination URL is changed manually, CASLINK can retain a limited history of domain changes. This is used as a factual update log rather than auto-generated keyword content.
