Hundreds of 404 errors are showing up for pages that never existed
-
For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style, but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal?
-
There have been a few people at Moz with similar problems with GSC. People always throw a few ideas around: maybe Google is creating URLs to try to find pages that it can't find through crawling links alone? Maybe another site was trying to hack your site by creating URLs they were hoping would trigger certain content on your site (a laughable idea now, but I remember my college professor showing us a site that put cost parameters in the URL during check out)?
However they got there, though, Eric and Chris gave you some good ways to make sure that you're not still in trouble (if you ever were).
Hope this helps!

I agree with Eric here so I won't repeat what he has said, simply offer additional suggestions.
Firstly, you can click on each entry from that Crawl Errors window in your screenshot and from the window that pops up, check out the "Linked From" tab. It will show you all the pages this broken one has links from.
If you're having no joy finding them on the pages manually, you can try the Screaming Frog SEO Spider. Crawl the site and if the 404s show up here (if they don't they probably don't exist anymore and you can mark them as "fixed" in Search Console) then click them and check out the "Linked From" tab at the bottom. This tool shows you not only the pages it's linked from but also the anchor text so you can go to the linking pages and use ctrl+f to find the offening link(s).
Hope that helps!

The 404 errors and other crawl data is provided by a separate database in Google, so the timing of the links and the data you're seeing isn't exactly "in sync" so to speak. I would do a few things--look at the pages to see if there's something on your site that might be causing the errors.
Another option is to look at the link data to see if there are any links pointing to those pages. I would use another source, such as OSE or Majestic.com to see if there are links pointing to those pages that Google isn't reporting (which is often the case).

Increase 404 errors or 301 redirects?
Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

What is the best way to find missing alt tags on my site (site wide - not page by page)?
I am looking to find all the missing alt tags on my site at once. I have a FF extension that use to do it page by page, but my site is huge and that will take forever. Thanks!!

Google's "cache:" operator is returning a 404 error.
I'm doing the "cache:" operator on one of my sites and Google is returning a 404 error. I've swapped out the domain with another and it works fine. Has anyone seen this before? I'm wondering if G is crawling the site now? Thx!

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.

How to find links to 404 pages?
I know that I used to be able to do this, but I can't seem to remember. One of the sites I am working on has had a lot of pages moving around lately. I am sure some links got lost in the fray that I would like to recover, what is the easiest way to see links going to a domain that are pointing to 404 pages?
