Client Error (4xx)
Error response.4xx
What it means
The URL returned a 4xx status. Search engines drop these from the index and any link equity pointing at them is wasted.
How to fix it
Restore the page, or 301 it to the closest equivalent. Then update the internal links that still point here — a redirect is a patch, not a fix.
