      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.

            GMB Bulk Upload Error

            Hello! I am continuing to have issues with the bulk upload option.Currently, there are 12 non-verified locations in a location group in my GMB account. I have approximately 6-8 more that need to be added to this group via bulk upload. When uploading the spreadsheet, I receive an error reading "You've exceeded the limit for the about of locations you can upload to Google My Business in a single day. Try again later." It seems to happen specifically to the locations that aren't in my GMB account already. The others, the ones already in the account, are fine and simply read "No updates" when the bulk upload sheet is read. Everything else is marked as an error. Why is it marking some listings as nonviable when they come in via the bulk verification spreadsheet, which has been downloaded directly from the links Google has provided, and filled in with the help of the sample and amenities list?How do we finish uploading all of the remaining locations?I have another group, separate group (same company, groups split into US and International) under my name that may also need a bulk upload - what can I do to avoid this error in the future? Can they still be bulk uploaded to my account after I upload the first location group's listings?If you could provide any guidance, I'd be very grateful.Thanks in advance!

            Intermittent 404 - What causes them and how to fix?

            Hi! I'm working on a client site at the moment and I've discovered a couple of pages that are 404ing but producing a 200 OK response. However, I have checked these URLs again and some are now producing a 404 Error response. No changes have been made (that I'm aware of) so it appears that the URLs are returning both 200 OK and 404 Error responses intermittently. Any ideas what could cause this and the best solution? Thanks!

            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?

            Expired domain 404 crawl error

            I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

            Best Practice on 301 Redirect - Images

            We have two sites that sell the same products. We have decided to retire one of the sites as we'd like to focus on one property. I know best practice is to redirect apples to apples, which in our case is easily done since the sites sold the same thing. www.SiteABC.com/ProductA can be redirected to www.SiteXYZ.com/ProductA. My question is how far does that thinking go regarding images? Each product has a main product page, of course, and then up to 6 images in some cases. Is it necessary to redirect www.SiteABC.com/ProductA-Image1.jpg to www.SiteXYZ.com/ProductA-Image1.jpg? Or can they all be redirected to just the product page?

            Backlinks that we have if they are 404?

            Hi All, Backlinks that we have if they are 404? Open site explorer shows 1,000 of links and when I check many are 404 and those are spammy links which we had but now the sites are 404 I am doing a link profile check which is cleaning up all spammy links Should i take any action on them? As open site explorer or Google still shows these links on the searches. Should we mention these URL's in disallow in Google webmaster. Thanks
