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).

Are image pages considered 'thin' content pages?
I am currently doing a site audit. The total number of pages on the website are around 400... 187 of them are image pages and coming up as 'zero' word count in Screaming Frog report. I needed to know if they will be considered 'thin' content by search engines? Should I include them as an issue? An answer would be most appreciated.

Is the Authority of Individual Pages Diluted When You Add New Pages?
I was wondering if the authority of individual pages is diluted when you add new pages (in Google's view). Suppose your site had 100 pages and you added 100 new pages (without getting any new links). Would the average authority of the original pages significantly decrease and result in a drop in search traffic to the original pages? Do you worry that adding more pages will hurt pages that were previously published?

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!!

Splitting Page Authority with two URLs for the same page.
Hello guys, My website is currently holding two different URLs for the same page and I am under the impression such set up is dividing my Page Authority and Link Juice. We currently have the following page with both URLs below: www.wbresearch.com/soldiertechnologyusa/home.aspx
Technical SEO | | JoaoPdaCosta-WBR
www.wbresearch.com/soldiertechnologyusa/ Analysing the page authority and backlinks I identified that we are splitting the amount of backlinks (links from sites, social media and therefore authority). "/home.aspx"
PA: 67
Linking Root Domains: 52
Total Links: 272 "/"
PA: 64
Linking Root Domains: 29
Total Links: 128 I am under the impression that if the URLs were the same we would maximise our backlinks and therefore page authority. My Question: How can I fix this? Should I have a 301 redirect from the page "/" to the "/home.aspx" therefore passing the authority and link juice of “/” directly to “/homes.aspx”? Trying to gather thoughts and ideas on this, suggestions are much appreciated? Thanks!0 -
404 error - but I can't find any broken links on the referrer pages
Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.
