      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.

                  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.

                  Sitemap error in Webmaster tools - 409 error (conflict)

                  Hey guys, I'm getting this weird error when I submit my sitemap to Google. It says I'm getting a 409 error in my post-sitemap.xml file (https://cleargear.com/post-sitemap.xml). But when I check it, it looks totally fine. I am using YoastSEO to generate the sitemap.xml file. Has anyone else experienced this? Is this a big deal? If so, Does anyone know how to fix? Thanks EwTswL4

                  Do I use /es/, /mx/ or /es-mx/ for my Spanish site for Mexico only

                  I currently have the Spanish version of my site under myurl.com/es/ When I was at Pubcon in Vegas last year a panel reviewed my site and said the Spanish version should be in /mx/ rather than /es/ since es is for Spain only and my site is for Mexico only. Today while trying to find information on the web I found /es-mx/ as a possibility. I am changing my site and was planning to change to /mx/ but want confirmation on the correct way to do this. Does anyone have a link to Google documentation that will tell me for sure what to use here? The documentation I read led me to the /es/ but I cannot find that now.

                  How to find all crawlable links on a particular page?

                  Hi! This might sound like a newbie question, but I'm trying to find all crawlable links (that google bot sees), on a particular page of my website. I'm trying to use screaming frog, but that gives me all the links on that particular page, AND all subsequent pages in the given sub-directory. What I want is ONLY the crawlable links pointing away from a particular page. What is the best way to go about this? Thanks in advance.

                  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

                  Increase 404 errors or 301 redirects?

                  Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

                  Can you have a /sitemap.xml and /sitemap.html on the same site?

                  Thanks in advance for any responses; we really appreciate the expertise of the SEOmoz community! My question: Since the file extensions are different, can a site have both a /sitemap.xml and /sitemap.html both siting at the root domain? For example, we've already put the html sitemap in place here: https://www.pioneermilitaryloans.com/sitemap Now, we're considering adding an XML sitemap. I know standard practice is to load it at the root (www.example.com/sitemap.xml), but am wondering if this will cause conflicts. I've been unable to find this topic addressed anywhere, or any real-life examples of sites currently doing this. What do you think?
