I am a member of a writing website called HubPages. We are each given a subdomain on which to write articles and are also given access to Google Webmaster Tools for our subdomain.Upon checking out my stats in Webmaster Tools, I see that Google is running into some 404 errors for two reasons:I took down an articleGoogle (or someone) got the url totally wrong.I am essentially getting view-only access for webmaster tools (HubPages must have set it up to allow view only so that a user doesn't mess things up) so I can't submit a url removal request to Google.Could this be hurting the SEO for my subdomain? If not, are there other problems that could occur for me or for HubPages by leaving these URLs as is and not submitting a removal request? Should HubPages be submitting url removal requests to Google for dead or incorrect urls?
SEO (or other) problems with a 404?
seo;google search console;404
If the page no longer exists, or the URL is invalid, then returning a 404 is fine. In those cases, it's good to see the 404 listed as a crawl error in Webmaster Tools, since that's what it should be showing :-). We did a blog post about this in May with more information: Do 404s hurt my site?
