Google’s John Mueller responded to a thread in Reddit about finding and fixing inbound broken links, offering a nuanced insight that some broken links are worth finding and fixing and others are not.
Reddit Question About Inbound Broken Links
Someone asked on Reddit if there’s a way to find broken links for free.
This is the question:
“Is it possible to locate broken links in a similar manner to identifying expired domain names?”
The person asking the question clarified if this was a question about an inbound broken link from an external site.
John Mueller Explains How To Find 404 Errors To Fix
John Mueller responded:
“If you want to see which links to your website are broken & “relevant”, you can look at the analytics of your 404 page and check the referrers there, filtering out your domain.
This brings up those which actually get traffic, which is probably a good proxy.
If you have access to your server logs, you could get it in a bit more detail + see which ones search engine bots crawl.
It’s a bit of technical work, but no external tools needed, and likely a better estimation of what’s useful to fix/redirect.”
In his response, John Mueller answers the question on how to find 404 responses caused by broken inbound links and identify what’s “useful to fix” or to “redirect.”
Mueller Advises On When Not To “Fix” 404 Pages
John Mueller next offered advice on when it doesn’t make sense to not fix a 404 page.
Mueller explained:
“Keep in mind that you don’t have to fix 404 pages, having things go away is normal & fine.
The SEO ‘value’ of bringing a 404 back is probably less than the work you put into it.”
Some 404s Should Be Fixed And Some Don’t Need Fixing
John Mueller said that there are situations where a 404 error generated from an inbound link is easy to fix and suggested ways to find those errors and fix them.
Mueller also said that there are some cases where it’s basically a waste of time.
What wasn’t mentioned was what the difference was between the two and this may have caused some confusion.
Inbound Broken Links To Existing Webpages
There are times when another sites links into your site but uses the wrong URL. Traffic from the broken link on the outside site will generate a 404 response code on your site.
These kinds of links are easy to find and useful to fix.
There are other situations when an outside site will link to the correct webpage but the webpage URL changed and the 301 redirect is missing.
Those kinds of inbound broken links are also easy to find and useful to fix. If in doubt, read our guide on when to redirect URLs.
In both of those cases the inbound broken links to the existing webpages will generate a 404 response and this will show up in server logs, Google Search Console and in plugins like the Redirection WordPress plugin.
If the site is on WordPress and it’s using the Redirection plugin, identifying the problem is easy because the Redirection plugin offers a report of all 404 responses with all the necessary information for diagnosing and fixing the problem.
In the case where the Redirection plugin isn’t used one can also hand code an .htaccess rule for handling the redirect.
Lastly, one can contact the other website that’s generating the broken link and ask them to fix it. There’s always a small chance that the other site might decide to remove the link altogether. So it might be easier and faster to just fix it on your side.
Whichever approach is taken to fix the external inbound broken link, finding and fixing these issues is relatively simple.
Inbound Broken Links To Removed Pages
There are other situations where an old webpage was removed for a legitimate reason, like an event passed or a service is no longer offered.
In that case it makes sense to just show a 404 response code because that’s one of the reasons why a 404 response should be shown. It’s not a bad thing to show a 404 response.
Some people might want to get some value from the inbound link and create a new webpage to stand in for the missing page.
But that might not be useful because the link is for something that is irrelevant and of no use because the reason for the page no longer exists.
Even if you create a new reason, it’s possible that some of that link equity might flow to the page but it’s useless because the topic of that inbound link is totally irrelevant to anyting but the expired reason.
Redirecting the missing page to the home page is a strategy that some people use to benefit from the link to a page that no longer exists. But Google treats those links as Soft 404s, which then passes no benefit.
These are the cases that John Mueller was probably referring to when he said:
“…you don’t have to fix 404 pages, having things go away is normal & fine.
The SEO ‘value’ of bringing a 404 back is probably less than the work you put into it.”
Mueller is right, there are some pages that should be gone and totally removed from a website and the proper server response for those pages should be a 404 error response.
