Google removed several structured data documentation pages from its Search Central site in September 2025. The retired URLs now redirect to the September 2025 Search Central updates page, following a June 2025 notice that these types are no longer supported.
What changed
Google lists the removals on its September 2025 documentation updates page. The updates entry includes links to the retired pages, which redirect back to the same updates entry.
- Course info
- Estimated salary
- Learning video
- Special announcement
- Vehicle listing
The Course info documentation URL now redirects to the updates log. See the September 2025 entry here: Search Central updates - September 2025.
Background
Google signaled these removals in its June 2025 blog post, stating the affected structured data types are no longer supported in Search.
Redirect behavior
The retired documentation URLs now redirect to the September 2025 updates page. Per Google's guidance, a 301 indicates a permanent redirect to a more accurate URL, while a 404 indicates a page was not found.
Why it matters
These removals confirm that the listed structured data types are no longer used for Search features. Site owners should review their markup and migrate to supported types as needed.
