When Google removes outdated documentation, most SEOs expect a simple 404 response or a redirect to updated resources. But in September 2025, Google took a different route—using 301 redirects that loop endlessly between missing pages and a changelog.
What Happened?
Google removed structured data documentation for items like:
- Course Info
- Estimated Salary
- Learning Video
- Special Announcement (404 as expected)
- Vehicle Listing
Instead of returning a 404 Page Not Found, Google set up 301 redirects pointing to a changelog. The catch? That changelog links back to the missing URLs—sending both users and crawlers into an infinite redirect loop.
Why It Matters
301 redirects usually signal that content has a permanent new home.
In this case, however, there’s no real replacement—just a loop. That creates:
A poor user experience (visitors trapped clicking back and forth).
Confusing signals for crawlers (infinite loops are not SEO-friendly).
An unusual precedent, since most site owners would issue a 404 or redirect to an explanatory post.
What SEOs Can Learn
While Google’s approach may be experimental, it’s not one to copy.
For most businesses and publishers, the best practices are:
- Use 404s or 410s when content is permanently gone.
- Redirect only when a relevant replacement exists.
- Provide context—if support for a feature or page ends, point users to a clear explanation rather than looping links.
This unusual redirect setup by Google is a reminder that even search giants don’t always follow the playbook SEOs recommend. For site owners, the safer route remains clear communication and clean redirects that actually help users.
