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).

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

301 Redirect non existant pages
Hi I have 100's of URL's appearing in Search Console for example: ?p=1_1 These go to on to 5_200 etc.. I have tried to do htaccess and the mod rewrite is on as I can redirect directories to the root i.e RewriteRule ^web_example(.*)$ /$1 [R=301,N,L] However I have tried all kinds of variations to redirect ?p= and either it doesn't work at all or it crashes the website. Can anyone point me in the right direction to fix this.

Should I disavow links from pages that don't exist any more
Hi. Im doing a backlinks audit to two sites, one with 48k and the other with 2M backlinks. Both are very old sites and both have tons of backlinks from old pages and websites that don't exist any more, but these backlinks still exist in the Majestic Historic index. I cleaned up the obvious useless links and passed the rest through Screaming Frog to check if those old pages/sites even exist. There are tons of link sending pages that return a 0, 301, 302, 307, 404 etc errors. Should I consider all of these pages as being bad backlinks and add them to the disavow file? Just a clarification, Im not talking about l301-ing a backlink to a new target page. Im talking about the origin page generating an error at ping eg: originpage.com/page-gone sends me a link to mysite.com/product1. Screamingfrog pings originpage.com/page-gone, and returns a Status error. Do I add the originpage.com/page-gone in the disavow file or not? Hope Im making sense 🙂

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?

Product Pages Outranking Category Pages
Hi, We are noticing an issue where some product pages are outranking our relevant category pages for certain keywords. For a made up example, a "heavy duty widgets" product page might rank for the keyword phrase Heavy Duty Widgets, instead of our Heavy Duty Widgets category page appearing in the SERPs. We've noticed this happening primarily in cases where the name of the product page contains an at least partial match for the desired keyword phrase we want the category page to rank for. However, we've also found isolated cases where the specified keyword points to a completely irrelevent pages instead of the relevant category page. Has anyone encountered a similar issue before, or have any ideas as to what may cause this to happen? Let me know if more clarification of the question is needed. Thanks!

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?
