    Hi All,

    We have recently discovered a site was linking to our site but it was linking to an incorrect url, resulting in a 404 error. We had only found this by pure chance and wondered if there was a tool out there that will tell us when a site is linking to an incorrect url on our site?

    Thanks 🙂

      If you dont have access to the logs that could be an issue - not really any automated tools out there as it would need to crawl every website and find 404 errors.

      I haven't tried this - so its just an idea. Go into GSC download all the links pointing to your site (and from places like Moz, Ahrefs, Majestic) and then chuck that list of urls into Screaming Frog or URL Profiler and look at external links and see if any are returning a 404. Not sure if this would work - its just an idea.

      Thanks

      Andy

        Great, will take a look. Maybe run a trial to see if it does exactly what I need 🙂

        Thanks for the info!

          Good idea!

          Although some of our clients that we do SEO for aren't hosting their websites on our server and we don't have access to their server logs etc.

          Was hoping for an automated dashboard like MOZ/Screaming Frog/ or A hrefs as mentioned above. Due to the amount of clients we have, opening up and running through all there Log files could be time consuming.

          Cheers for the info though, may come in use in the future, or to someone else reading this 🙂

            Hi

            The best way I have found is to look in your server logs, its the only true place to find out what Google is doing on your site.

            Download the logs and look at all the 404 errors - quite simple and depending on size of your logs can take you around 5 minutes worth a work - the longer time period you can analyse in your logs the better.

            Thanks

            Andy

              Hi David.

              Ahrefs.com offers that service: broken links.

              Another way to do that search could be this: Downloading the historic backlinks list and with a mass checker, check where do they point nowdays. I've used GScraper and its option to crawl outbound links.

              Best Luck.
              GR.

                Google Search Console Showing 404 errors for product pages not in sitemap?

                search console 404 error 404s

                We have some products with url changes over the past several months. Google is showing these as having 404 errors even though they are not in sitemap (sitemap shows the correct NEW url). Is this expected? Will these errors eventually go away/stop being monitored by Google?

                Does anyone know the linking of hashtags on Wix sites does it negatively or postively impact SEO. It is coming up as an error in site crawls 'Pages with 404 errors' Anyone got any experience please?

                Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO.  It is coming up as an error in site crawls 'Pages with 404 errors'  Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag.  Seems a bit of a strange approach to me.

                404 Error Pages being picked up as duplicate content

                Hi, I recently noticed an increase in duplicate content, but all of the pages are 404 error pages. For instance, Moz site crawl says this page: https://www.allconnect.com/sc-internet/internet.html has 43 duplicates and all the duplicates are also 404 pages (https://www.allconnect.com/Coxstatic.html for instance is a duplicate of this page). Looking for insight on how to fix this issue, do I add an rel=canonical tag to these 60 error pages that points to the original error page? 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?

                Google's "cache:" operator is returning a 404 error.

                I'm doing the "cache:" operator on one of my sites and Google is returning a 404 error. I've swapped out the domain with another and it works fine. Has anyone seen this before? I'm wondering if G is crawling the site now? Thx!

                404 errors on non-existent URLs

                Hey guys and gals, First Moz Q&A for me and really looking forward to being part of the community. I hope as my first question this isn't a stupid one but I was just struggling to find any resource that dealt with the issue and am just looking for some general advice. Basically a client has raised a problem with 404 error pages - or the lack thereof- on non-existent URLs on their site; let's say for example: 'greatbeachtowels.com/beach-towels/asdfas' Obviously content never existed on this page so its not like you're saying 'hey, sorry this isn't here anymore'; its more like- 'there was never anything here in the first place'. Currently in this fictitious example typing in 'greatbeachtowels.com/beach-towels/asdfas**'** returns the same content as the 'greatbeachtowels.com/beach-towels' page which I appreciate isn't ideal. What I was wondering is how far do you take this issue- I've seen examples here on the seomoz site where you can edit the URI in a similar manner and it returns the same content as the parent page but with the alternate address. Should 404's be added across all folders on a site in a similar way? How often would this scenario be and issue particularly for internal pages two or three clicks down? I suppose unless someone linked to a page with a misspelled URL... Also would it be worth placing 301 redirects on a small number of common mis-spellings or typos e.g. 'greatbeachtowels.com/beach-towles' to the correct URLs as opposed to just 404s? Many thanks in advance.
