Now that we've
bid farewell to soft 404 errors,
in this post for 404 week
we'll answer your burning 404 questions.
How do you treat the response code 410 "Gone"?
Just like a 404.
Do you index content or follow links from a page with a 404 response code?
We aim to understand as much as possible about your site and its content. So while we wouldn't
want to show a hard 404 to users in search results, we may utilize a 404
error page's content or links if it's detected as a signal to help us better understand your site.
Keep in mind that if you want links crawled or content indexed, it's far more beneficial to
include them in a page that's not 404.
What about 404 errors with a 10-second meta refresh?
Yahoo! currently utilizes this method on their 404 errors. They
respond with a 404,
but the 404 content also shows:
<meta http-equiv="refresh" content="10;url=https://www.yahoo.com/?xxx" />. We feel
this technique is fine because it reduces confusion by giving users 10 seconds to make a new
selection, only offering the home page after 10 seconds without the user's input.
Should I 301 redirect misspelled 404 errors to the correct URL?
Redirecting with 301 status 404 errors is a good idea when it's helpful
to users (that is, not confusing like soft 404 errors). For instance, if you notice
that the
Crawl Errors
of Webmaster Tools shows a 404 for a misspelled version of your URL, you can
301 the misspelled version of the URL to the correct version.
For example, if we saw this 404 in Crawl Errors:
https://www.google.com/webmsters <-- typo for "webmasters"
we may first correct the typo if it exists on our own site, then 301 the URL to the
correct version (as the broken link may occur elsewhere on the web):
https://www.google.com/webmasters
Have you seen any good 404 errors?
Yes, we have! (Confession: no one asked us this question, but few things are as fun to discuss as
response codes. :) We've put together a list of some of our favorite
404 pages. If you have more 404 related questions, let us know, and
thanks for joining us for 404
week!
