    I have a client with a lot of 404 errors from Web Master Tools, and i have to go through and check each of the links because

    • Some redirect to the correct page
    • Some redirect to another url but its a 404 error
    • Some are just 404 errors

    Does anyone know of a tool where i can dump all of the urls and it will tell me

    • If the url is redirected, and to where
    • if the page is a 404 or other error

    Any tips or suggestions will be really appreciated!

    Thanks SEO Moz'rs

      Check out the free Xenu Link Sleuth and this post: http://www.seomoz.org/blog/xenu-link-sleuth-more-than-just-a-broken-links-finder

      I haven't used it myself (yet), but Screaming Frog could help as an alternative, though the full version is paid. This post compares the two: http://www.seomoz.org/blog/crawler-faceoff-xenu-vs-screaming-frog

        Have you tried the SEOmoz Crawl Diagnostics report? That will show the 404 errors and the pages on the site that have the links to those pages.

          520 Error from crawl report with Cloudflare

          crawler cloudflare rogerbot 520 server error

          I am getting a lot of 520 Server Error in crawl reports. I see this is related to Cloudflare. We know 520 is Cloudflare so maybe the Moz team can change this from "unknown" to "Cloudflare 520". Perhaps the Moz team can update the "how to fix" section in the reporting, if they have some possible suggestions on how to avoid seeing these in the report of if there is a real issue that needs to be addressed. At this point I don't know. There must be a solution that Moz can provide like a setting in Cloudflare that will permit the Rogerbot if Cloudflare is blocking it because it does not like its behavior or something. It could be that Rogerbot is crawling my site on a bad day or at a time when we were deploying a massive site change. If I know when my site will be down can I pause Rogerbot? I found this https://developers.cloudflare.com/support/troubleshooting/general-troubleshooting/troubleshooting-crawl-errors/

          How to get rid of bot verification errors

          crawl errors 4xx error

          I have a client who sells highly technical products and has lots and lots (a couple of hundred) pdf datasheets that can be downloaded from their website. But in order to download a datasheet, a user has to register on the site. Once they are registered, they can download whatever they want (I know this isn't a good idea but this wasn't set up by us and is historical). On doing a Moz crawl of the site, it came up with a couple of hundred 401 errors. When I investigated, they are all pages where there is a button to click through to get one of these downloads. The Moz error report calls the error "Bot verification". My questions are:
          Are these really errors?
          If so, what can I do to fix them?
          If not, can I just tell Moz to ignore them or will this cause bigger problems?

          Topic Cluster: URL Best Practices

          I'm trying to be mature and employ the Topic Cluster strategy to my content. In doing so I realized there are a few URL options. Some more difficult to execute than others. -Is it important to call out the Pillar Topic in your subtopic URL?
          -Does the Pillar Topic need to have its own landing page? (As opposed to just being part of the blog.) Here's an Example: My Pillar is: Inbound vs. Outbound
          My subtopic is: Marketing Platforms Here are the URL options I can think of... Option 1: https://pipelineinbound.com/blog/inbound-vs-outbound-marketing-platforms/ Option 2: https://pipelineinbound.com/blog/which-marketing-platforms/ Option 3: https://pipelineinbound.com/blog/marketing-platforms-inbound-vs-outbound/ Option 4 (Hardest): https://pipelineinbound.com/inbound-vs-outbound/marketing-platforms/ Are there some fundamental best practices for URL structure and Link Building as it pertains to Topic Clusters? Thanks!

          422 vs 404 Status Codes

          We work with an automotive industry platform provider and whenever a vehicle is removed from inventory, a 404 error is returned. Being that inventory moves so quickly, we have a host of 404 errors in search console. The fix that the platform provider proposed was to return a 422 status code vs a 404. I'm not familiar with how a 422 may impact our optimization efforts. Is this a good approach, since there is no scalable way to 301 redirect all of those dead inventory pages.

          Best strategy to handle over 100,000 404 errors.

          I recently been given a site that has over one-hundred thousand 404 error codes listed in Google Webmasters. It is really odd because according to Google Webmasters, the pages that are linking to these 404 pages are also pages that no longer exist (they are 404 pages themselves). These errors were a result of site migration that had occurred. Appreciate any input on how one might go about auditing and repairing large amounts of 404 errors. Thank you.

          Are 404 Errors a bad thing?

          Good Morning... I am trying to clean up my e-commerce site and i created a lot of new categories for my parts... I've made the old category pages (which have had their content removed) "hidden" to anyone who visits the site and starts browsing.  The only way you could get to those "hidden" pages is either by knowing the URLS that I used to use or if for some reason one of them is spidering in Google. Since I'm trying to clean up the site and get rid of any duplicate content issues, would i be better served by adding those "hidden" pages that don't have much or any content to the Robots.txt file or should i just De-activate them so now even if you type the old URL you will get a 404 page... In this case, are 404 pages bad?  You're typically not going to find those pages in the SERPS so the only way you'd land on these 404 pages is to know the old url i was using that has been disabled. Please let me know if you guys think i should be 404'ing them or adding them to Robots.txt Thanks
