          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.

                      SEO advice on ecommerce url structure where categories contain "/c/"

                      Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:
                      https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a. 
                      https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
                      https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus

                      Trying to find all internal links to a specific page (without index)

                      Hi guys -- Still waiting on Moz to index a page of mine. We launched a new site over two months ago. In the meantime, I really just need a list of internal links to a specific page because I want to change its URL. Does anybody know how to find that list (of internal links to 1 of my pages) without the Moz index? I appreciate the help!

                      Yoast SEO. After set up 404 error pages

                      Hello all, Something strange happened with my blog site. I recently signed to MOZ tools. Initially everything was fine, but during my last crawl I got loads of 404
                      pages. Few days ago I was tweaking some settings in SEO plugin according to this post https://a-moz.groupbuyseo.org/blog/setup-wordpress-for-seo-success What I noticed was that 404 pages were coming from my blog posts, but for
                      some reason category was missing in those posts. For example this link is 404
                      https://a-fotografy.co.uk/inchcolm-island-wedding-photography-bailie The one with category is https://a-fotografy.co.uk/wedding-pictures/inchcolm-island-wedding-photography-bailie/ So basically for some reason category was missing. Please let me know how can I fix this instead of doing hundreds of
                      redirects now. Thank you,
                      Regards,
                      Armands

                      Why is Google Webmaster Tools showing 404 Page Not Found Errors for web pages that don't have anything to do with my site?

                      I am currently working on a small site with approx 50 web pages.  In the crawl error section in WMT Google has highlighted over 10,000 page not found errors for pages that have nothing to do with my site.  Anyone come across this before?

                      Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?

                      Dear all, starting with my .htaccess file: RewriteEngine On
                      RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
                      RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html 
                      RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
                      2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

                      Wordpress categories causing too many links/duplicate content?

                      I've just added categories to my wordpress site and some of the posts show in several of the categories. Will this cause me duplicate content problems as I want the category pages to be indexed? Also as I add more categories I'm creating more links on the page. They can't be seen to the user as I have a plugin that creates drop down categories. When I go to 'view source' though all the links are there so google will see lots of links. How can I fix the too many links problem? And should I worry about duplicate content issue?

                      404 error - but I can't find any broken links on the referrer pages

                      Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.

                      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!
