The internet has at least 4.46 billion indexed pages currently active (this is most likely a gross underestimate). Millions of new pages are published every day, and millions of old pages are removed.
So what happens to the URL when a page is removed?
When a page is removed from a server, any links to that page usually become 404 errors (this is the default response for most servers).
There are many good reasons to make sure 404 errors are fixed, but what might surprise you is that there are also good reasons to let some remain.
We’re here to help you understand the best ways to handle a 404 error and whether you should fix it or forget it.
