404 Errors
-
Hello Team,
I noticed that my site has 1,000s of 404 errors. Not sure how this happened, maybe when I updated our CMS.
My question is, should I worry about them. Should I delete them or just leave them alone.
Thank you for your feedback!

No worries,
Sorry - my mistake - I didn't mean Open Site Explorer. You can find the 404 report in your campaign settings in your SEOMoz dashboard. Click Errors and Download as CSV top right. You can sort the CSV in Excel to group all of your 404's and easily find the referral page.
If for some reason you can't access the Errors page in your dashboard (still waiting for your report to finish etc), you can do pretty mush the same with software called Xenu Link Sleuth.
Cheers,

Also, ask your hosting administrator, to help; they often can fix 404, & 301 server side.

Thank you very much!!!
How do I find the 404's on Open Site Explorer, would that be on the top pages tab?
I'll make sure to send out some love from one of my sites to your confetti

Hi there,
Yes - you should definitely worry about them. Get them fixed or add a 301 redirect to a relevant page.
In my experience, lots of 404's often stem from a small number of places such so it shouldn't be a case of having to manually fix every single link. If you fix the link in one place, you'll probably fix it in hundreds of others. Download a CSV of your broken links from Open Site Explorer. You'll easily be able to see the referring page and fix the links.
Hope that helps.

I have over 3000 4xx errors on my site for pages that don't exist! Please help!
Hello! I have a new blog that is only 1 month old and I already have over 3000 4xx errors which I've never had on my previous blogs. I ran a crawl on my site and it's showing as my social media links as being indexed as pages. For example, my blog post link is:
Technical SEO | | thebloggersi
https://www.thebloggersincentive.com/blogging/get-past-a-creative-block-in-blogging/
My site is then creating a link like the below:
https://www.thebloggersincentive.com/blogging/get-past-a-creative-block-in-blogging/twitter.com/aliciajthomps0n
But these are not real pages and I have no idea how they got created. I then paid someone to index the links because I was advised by Moz, but it's still not working. All the errors are the same, it's indexing my Twitter account and my Pinterest. Can someone please help, I'm really at a loss with it.

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? Screen-Shot-2016-02-29-at-9.35.18-AM.png

Are W3C Validators too strict? Do errors create SEO problems?
I ran a HTML markup validation tool (http://validator.w3.org) on a website. There were 140+ errors and 40+ warnings. IT says "W3C Validators are overly strict and would deny many modern constructs that browsers and search engines understand." What a browser can understand and display to visitors is one thing, but what search engines can read has everything to do with the code. I ask this: If the search engine crawler is reading thru the code and comes upon an error like this: …ext/javascript" src="javaScript/mainNavMenuTime-ios.js"> </script>');}

The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element
in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).
One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create
cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer
the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error). and this... <code class="input">…t("?");document.write('>');}</code> ✉ The element named above was found in a context where it is not allowed.

404 vs. 200?
Is it better to have an error page return a 404 or 200? If I change it to 200, will I still be able to see reports of 404's and/ or broken links? Is there a valid SEO reason that Google would have for not wanting error pages to return 200? In other words, is there any SEO reason to absolutely change it to return a 404? I would rather let it return 200 if no priority reason to change. [title edited by staff to provide clarity]
